INTRODUCTION
Mathematics is a core subject in secondary schools and covers many aspects. The content of the syllabus of Mathematics Secondary School Integrated Curriculum (KSSM, 2016) covers the knowledge and skills of three interrelated areas namely, Number, Shape & Space and Relationship & Statistics. According to Owens and Outhred (2006) one of the most important topics in the mathematics curriculum is Geometry because it is a rich source of visualization for arithmetical, algebraic and also statistical concepts. It is imperative for educators to look at ways to enhance the teaching and learning of circle, which is fundamental at the secondary level. Thus, mastery of geometry knowledge should be enhanced from time to time in order to provide the societies to meet the needs of development and establish a developed country (Ojose, 2011).
Geometry is connected to every component in the mathematics curriculum and to a multitude of situations in real life; hence students require better understanding in geometry (Erdogan, Akkaya, & Celebi Akkaya, 2009;Yegambaram & Naidoo, 2010). Many teachers have observed that students have numerous misconceptions about geometry when a teacher discusses a geometry proof problem in class such as lack of background knowledge, reasoning and basic operation mistakes (Lavy & Leron, 2004;Özerem, 2012). Because of the misconceptions, students had difficulties to manipulate and understand circle properties (Prescott, Mitchelmore, & White, 2002). Zanzali and Nam (2000) & Heong (2005) stated that along with these difficulties, Malaysian students' mastery of problem-solving is still low and there is a need for teachers to examine their practices that consists of their choice of teaching methods and instructional activities. A number of researchers have experimented different ways of teaching and found serious shortcomings in www.mojet.net geometry learners: these include incomplete comprehension of the problem and mathematical symbols, and lack of ability in producing proofs based on direct visual elements (Adolphus, 2011;Chazan, 1993;Healy & Hoyles, 2000).
Teaching and learning mathematics traditionally were only taught using the chalk-and-talk method which focused on a concept that did not enable students to obtain a deep understanding of the concepts, gave little involvement in classroom discussions and created difficulties in visualizing the diagram (Brahier, 2016). This supported by Tay and Wonkyi (2018) stating that traditional teaching approach made students difficult to construct, visualize and justify geometrical concepts especially circle theorems. Moreover, this teaching approach focus on students memorizing the computations and lack of importance are given on students thinking and reasoning skills. Hence, teacher dominate the classroom and students be the listener (Mereku, 2010). Lack of praticipations and communication leads to failure in problem-solving skills and performance. Therefore, computer-based teaching and learning process needed to improve student proficiency in math learning, facilitate and accelerate students' understanding of circle concepts and supply more information and knowledge through the inquiry findings. Computer software used in the teaching and learning process will help students understand and develop concepts and principles of math easily and effectively (Dimakos & Zaranis, 2010). Using appropriate technology can help to improve student's performance and achievement in learning (Jackiw, 2001;Sinclair, 2003). This situation invariably results in students due to experiencing learning of circle as dull, dry and boring instead of fun, enjoyable and valuable. In contrast, students' positive attitude and beliefs toward learning mathematics can be fostered if students find learning circle useful and enjoyable. This will result in greater improvements in their mathematics performance (Ignacio, Nieto, & Barona, 2006).
The National Council of Teachers of Mathematics (NCTM) identified technology as one of the principles for teaching and learning mathematics. Moreover, NCTM recommended technology as a teaching and learning instrument in geometry lessons (NCTM, 2002). According to Meng and Sam (2013) and Guven and Kosa (2008), teachers viewed Geometry's Sketchpad (GSP) as a useful tool in geometry as it provides an environment in which students can explore geometric relationships and make and test conjectures. The features offer opportunities to the student to explore, develop and learn three-dimensional geometry because some measurements such as angle, length and surface area obtained on the screen via the software (Guven & Kosa, 2008). Geometer's Sketchpad enables students to build exact figures and control them intuitively (Oldknow, Taylor, & Tetlow, 2010). GSP helps students to create mental models for contemplating geometric shapes and their properties. Satterfield (2001) recommended that Geometer's Sketchpad is perfect for agreeable adapting additionally serves educators well as a show apparatus so that if the teacher has a restricted measure of computers, students can still comprehend the visual parts of Geometry.
Though it is encouraging to see that several previous studies have demonstrated positive effects of technology based instructional approach lessons on students' achievement. Therefore, it is the aim of this study focused on the effectiveness of using Geometer's Sketchpad (GSP) among form two circles topics involving subtopic namely in understanding and using the features circle involving symmetry, chords, and arcs. This software, GSP is suitable for this topic because, through this software, students can explore activities such as drawing, measuring angles and length of a circle. This can stimulate their interest to try it; indirectly GSP helps increase students' interest as well as deepen their understanding on the concepts of circle. Moreover, will enable students visualize geometric images in GSP interface and discover properties about circle.

OBJECTIVES AND RESEARCH QUESTIONS
The purpose of this study is identifying effectiveness of using Geometer's Sketchpad for teaching and learning Circle topic among Form Two students. This study aimed at addressing the following research questions: 1. Ho 1: What is the effectiveness of using GSP on students' understanding of circle as compared to the traditional approach.
2. Ho 2: What are the students' perceptions about using the Geometers' Sketchpad in the learning of circle?

Research Design
A quasi-experimental non-equivalent pretest and posttest design study was carried out using geometer activities based on GSP software to improve Form Two student's performance in circle topic.

Participants
Participants for this study were Form Two students selected from a school in Klang. Two intact classes consisting of 82 students in total were selected for this study. One of the classes was assigned as an experimental group while the other became the control. The experimental group consisted of 40 students while the control group consisted of 42 students. The researcher taught both the groups.

Data Collection Tool
Pre and post-test was used to obtain data. Pre and post-test consists of multiple-choice questions covering the topics and structure form two circles by topics taught according to the appropriate level with students (easy, medium and hard). Question test consists of 20 questions divided into subtopics identify and draw parts of circle, understand and solve concepts of circumference, arc, area and sector of circle. The time allotted was 45 minutes. All respondents had been given the same test paper. The design of the pre-test and post using two measurements (measurements of the same) to the independent variables (learning circle) that before and after the independent variable (Software Geometer's Sketchpad) manipulated. With this instrument, the researcher can identify and make comparisons between the two groups thus determining whether there is any impact in learning mathematics using GSP.
The researchers utilized the instrument from Christensen and Stephens (2003) and Noraini Idris et al. (2003) about students' perceptions towards the usage of Geometer's Sketchpad software. The instruments were adopted into this research and distributed among students in the experimental group. The questionnaire consists of 4 sections, namely: i. students' perceptions on the usage of Geometer's Sketchpad, ii. students' perceptions on how Geometer's Sketchpad helps understanding, iii. students' perception on their abilities to communicate when using Geometer's Sketchpad iv. students' perception on their attitudes towards geometry, when using Geometer's Sketchpad.
As for the scale used, the questionnaire adopted a five-point Likert scale format to assess students' responses for each related section. (1-Strongly Disagree, 2-Disagree, 3-Neutral, 4-Agree, 5-Strongly Agree).

This design consists of two groups of respondents, one as a treatment group and the other as the control group. Meanwhile, a pretest provides a measure on some attribute or characteristic assessed for students in both groups before they receive an intervention. A posttest is a measure on some attribute or characteristic that is assessed for students after an intervention. The comparison of pretest and posttests determined the effectiveness of the GSP. This design was chosen because it is suitable for assessing changes in knowledge, awareness, skills, attitudes, beliefs and behavior of respondents (Davis, 2002). The study showed that the selection of the design of "pre-post" brings advantages such as it takes less time, is less intrusive and for self change report, avoids protest sensitivity and response shift bias protest that result from overestimation or underestimation (Creswell, 2002;Klatt & Taylor-Powell, 2005). In addition, the experimental group has to answer a set of questionnaires to gauge their perceptions towards the usage of Geometer's Sketchpad software. Figure 2 shows the flow chart of the research process. The collected data consists of data from pre and post-test performance of students. SPSS software has been used to analyze this data. Analyzing data involves Descriptive Statistics and Statistical Inference. Descriptive statistics were used to show the marks mean, variance, standard deviation and minimum and maximum marks. Next, Statistical Inference used to test hypotheses about the differences in student achievement in accordance with the methods used to analyze the distribution of the t-test. Geometer's Sketchpad effectiveness was tested by comparing the difference in the mean values for the pre test and posttest for both groups (control and experimental). Next, the differences between the mean values of these tests were analyzed using paired t-test analysis. This method is suitable for finding the difference of two mean values for the same group. The effectiveness of GSP in improving student achievement was supported where there is a significant improvement from pre-test to post-test of the experimental group but not in the control groups.

Validity and Credibility
The instrument used to assess effectiveness of GSP based instruction in enhancing students' statistical reasoning had undergoes pilot study before it can be administered. A pilot study was intended to examine any weakness in the research design. The pilot study was conducted under the same condition using similar ability respondents and the same instrument planned for the real study. There were 30 students participated, the pre-post test instrument obtained Cronbach Alpha of .74 hence the coefficient indicated that the instrument was reliable. Questionnaire items required responses on a five-point Likert scale with scores ranging from "strongly disagree" to "strongly agree". A reliability test was conducted on the Students' Perception Questionnaire obtained a Cronbach alpha of 0.91, indicating internal consistency of the scale. In addition, two experienced teachers validated the test and questionnaire on the concepts, skills, difficulty level and clarity of the questions as well as the language. Their comments and recommendations were used to improve the questionnaire.

FINDINGS
The analysis and findings mentioned in the research methodology is presented in this chapter.

Ho1: What is the effectiveness of using GSP on students' understanding of circle as compared to the traditional approach?
To answer the first research question, an independent samples t-test was conducted to determine whether the mean score of the pre-test differed between the control and experimental group. Review of the Shapiro-Wilk test of normality (S-W = .98, df = 82, p = .51) indicated that normality assumption was not violated.  Table 1 shows that the experimental group obtained pre-test mean score of 59.98 (M=59.98, SD=15.03) meanwhile the control group obtained a mean score of 56.64 (M=56.64, SD=13.91). The mean score difference between the groups was 3.34 with a t(80)= -1.043, p> .05. Therefore, we fail to reject the null hypothesis indicating that the difference in the mean score of the two groups was not significant. This result showed that both the students in the control and experiment group were similar in abilities before the treatment was administered.
Meanwhile the control group's mean score between pretest (M=56.64) and posttest (M=59.10) showed that the students had scored better after taught in traditional group. This is because the pretest was done before the lesson begins whereby the students are with lack of knowledge in the particular topic. After conduct the lessons, the students gained understanding on the statistical reasoning, this is the main reason why their score is improved. However, this study intend to examine effectivenss of two different teaching method. Hence there is a need to compare between traditional method and GSP method.
In the post-test the experimental group has a mean score (M=71.60, SD=13.47) while the control group has a mean (M=59.10, SD=13.50). The mean score difference between the groups was 12.5. The computed t-value between the post-tests of the experimental and control groups is t(80)=−4.197, p<0.05. This indicates that there is a significant difference between the post test of both groups. Based on Cohen's (1988) criteria, the effect size of 0.89 is large. These results indicate that learning Circle using GSP do differs in students' achievement. This finding illustrated that the experimental group students performed better using Geometer's Sketchpad than the control group using the traditional learning method. A paired sample t-test was conducted to compare the pre-test and post-test for experimental group with the mean and standard deviation score score (M=6.93, SD=9.99). The results as illustrated in Table 2 www.mojet.net shows that the mean score difference between the post-test and pre-test was 6.93 with a t-value obtained was, t(40)=6.28, p<0.05. The null hypothesis was rejected indicating that the differences between the pre and post test score was significant. This result showed that learning using GSP improves students' achievement in Circle.  Table 3 showed the respond of the students' perception on the use of GSP in teaching and learning in Circle. It showed that the GSP able to illustrate diagrams clearly M = 4.20) and the students acquired a good experiences with the use of GSP (M = 3.83). On the other hand, most of students also agreed that they had enjoyed the lesson with the use of GSP (M = 4.15), which make them confident in solving problem involving Circle (M = 3.20). Another important aspect is the communication with both teacher and friends (M = 4.25). Thus, most students agreed this helped the discussions in classroom (M= 4.25).

Ho 2: What are the students' perceptions about using the Geometers' Sketchpad in the learning of Circle?
For more detail, students' responses were again computed and divided into four categories. The selected categories of the responses considered as: i. students' perceptions on the usage of Geometer's Sketchpad, (Item 1, 11 and 14) ii. students' perceptions on how Geometer's Sketchpad helps understanding, (Item 2, 5, 6, 8, 10 and13) iii. students' perception on their abilities to communicate when using Geometer's Sketchpad. (Item 3 and 9) iv. students' perception on their attitudes towards geometry, when using Geometer's Sketchpad.
(Item 4, 7 and 12) The results were tabulated according to the categories and summarized in frequencies and percentages. Table 4 showed the students' perception on the usage of GSP.   Table 4, the first category that is usage of GSP, the results showed that 65% of students agreed that GSP is easy to use. A small percentage (12.5%) was not sure; meanwhile remaining 22.5% of students did not agree that it was easy. As whether GSP guided students to solve the difficult sums, only 40% agreed and most of students (47.5%) were not sure. Five out of forty disagreed. The high percentage of not sure for item number 1 and 11 might be due to the seldom use of the computer in classroom. However, the majority of students agreed (72.5%) that they acquired a good experience with the use of GSP, while only three out of forty disagreed. Remaining 20% of students were uncertain.

The next category inquired on whether using GSP could help the students in their understanding of mathematics specifically in topic circle. As in the following Table 5, almost all the students (90%) agreed that the GSP able to illustrate diagrams clearly.  Only 5% was neutral or uncertain. Two out of forty disagreed. For the next item, number 5, 65% of students agreed that they learn the topic circle in greater depth. The remaining students 35% were uncertain while no students disagreed. The percentage 55% of students agreed that they able to draw and solve problem with GSP whereas 30% of students disagreed. 10 out of forty students were uncertain. Most of students agreed (77.5%) that they understand the lesson well when using GSP compared to textbooks. Only 5 students (12.5%) disagreed and the balance of 4 students (10%) were unsure. The next item number 10 showed majority of students were neutral (45%) on being confident at solving problem in the topic circle and only 37.5% agreed that they are confident in problem solving. Meanwhile rest of students (12.5%) disagreed. Since students are not highly exposed to learning with technologies hence they still had uncertainty in utilizing technology in learning mathematics. Lastly, item number 13 which stated that using GSP is a good way for students to learn circle and majority of students had agreed (60%). There are only 5 students (12.5%) www.mojet.net disagreed and 25% of the students were uncertain.  The third category is on the abilities to communicate when using GSP. Table 6 showed that majority of the students agreed (95%) that GSP had helped them in their classroom discussion and only 5% were uncertain. Under classroom interaction with both teachers and peers, again the majority of students agreed (82.5%) that GSP encourages them to interact. Only a small percentage disagreed (2.5%) and the remaining 15% were not sure.  Table 7 showed the students' attitudes towards mathematics. A total of 85% of the students agreed that learning mathematics is more fun with GSP while 15% were uncertain. In fact none of the students disagreed. About 65% of the students agreed that learning mathematics is easier with GSP while 30% of students were uncertain. Only 2 out of forty (5%) disagreed. The high percentage of not sure responses might be due to student unfamiliarity with GSP. However, majority of students agreed (87.5%) that they enjoy learning mathematics with GSP. Least percentage of students had disagreed (2.5%) and only four students were not sure.
In summary, the results concluded that most of the students who use GSP enjoyed mathematics and found the lesson more interesting. The GSP had the ability to construct and solve problem involving circle and other geometer topics. Plenty of students also testified that they are able to communicate with teacher and friends and help in classroom discussions.

DISCUSSION AND CONCLUSION
In this study, Geometer's Sketchpad was used as a tool in teaching and learning Circle. The results showed that the mean score of post-test result for the treatment group and the control group have a significant differences. Therefore, the use of computer-aided teaching aids which is GSP had make an impact on teaching and learning Circle topic. Students performed better after the using the GSP. The results of this study are consistent with several studies that discovered the use of interactive multimedia is necessary to www.mojet.net encourage and improve students' understanding in mathematics that can enable student to achievement better in Mathematics (Bakar, Ayub, Luan, & Tarmizi, 2010;Dimakos & Zaranis, 2010;Marzita & Rohaidah, 2004;Tezer & Kanbul, 2009;Young, Gorumek, & Hamilton, 2018). Students can obtain better understanding from well-structured instructional activities together with teacher's guidance and suitable facilities (McKnight et al., 2016;Meng & Sam, 2013).
The result obtained from students' perception questionnaire from the experimental group shows positive feedback from the students, which implied that the learning circle with Geometer's Sketchpad had been beneficial and useful for the students. Students feel it is exciting when the learning style is different from the conventional method. Besides that, technology in education especially in mathematics helps to create a less stressful environment for both teachers and students. Ecspecially when the students are able to communicate and involve in classroom discussions with teachers and friends, the classroom environment in will be more enjoyable and fun (Oldknow & Taylor, 2002). Indirectly, students will be more capable in solving mathematical problems (Zakaria, Daud, & Nordin, 2007).

IMPLICATIONS AND LIMITATIONS
The findings of this study have raised implications for teachers and students as well. Teachers could save their time preparing teaching tools by using ICT as the teaching tool. Use of mathematical software could create more meaningful classroom teaching. GSP is a great platform for the students to learn independently by exploring, analyzing and collaborating. However, the students should be given more time to experience learning with GSP.
It is recommended that more study on the application of GSP should be carried out in future to promote better learning style among students and enhance higher order thinking skills. Moreover, teachers are catalysts in assisting students in effective use of technology while learning mathematics. Therefore, study on other dynamic and interactive learning environments for mathematics, such as Cabri, GeoGebra, Geometer Sketchpad and Fathom can be of great help for the teachers in improving student knowledge and understanding of mathematics, especially in dynamic and complicated subject matters. By means of the materials prepared by using these types of software, students can configure mathematical concepts with their own generalizations with the teacher's guidance. For this reason, it is very important to conduct research so that can provide training to the implementers or teachers on how to carry out lesson using technology and what kind of materials they can create by software for use in such instruction.

The Local Wisdom-Based STEM Worksheet to Enhance the Conceptual Understanding of Pre-service Physics Teacher

The STEM (Science, Technology, Engineering, Mathematics) approach plays an important role in developing students’ abilities. The ability to combine science, technology, technical expertise, and mathematics is a tool that can help human life can be created. Of course, the application of STEM needs to be assisted by teaching materials in the form of Worksheets. With the STEM implementation worksheet, it can be more easily implemented without the lecturer having to explain each material fully. Because it must be students who develop their abilities. Following constructivist learning theory, by constructing one’s knowledge, the knowledge will be stored longer in memory. The ability in STEM is also very important in the current era of globalization. With the rapid advancement of technology, each individual is required to continue to innovate in developing a technology product. The basic ability that students need to have in learning basic physics is to understand a concept. A good understanding of the concept will be very supportive when prospective teachers later teach. It is expected that through the application of STEM, students are directly involved actively in designing and making products, and understanding concepts can be better. Products made by students must be really needed so that they can be used every day. It is better if the product utilizes local wisdom that is around the student environment. The product to be made is to convert the abundant solar thermal energy in Serang into a heater that can be used for cooking. It is a renewable energy because the heat in Serang is sweltering up to 32° C, so it can be used more than just drying. Based on these needs, mak a worksheet STEM based on local wisdom needs to be applied in learning. The results of this study stated that the local wisdom-based STEM worksheet on temperature and heat material for Physics teacher candidates was developed as a learning medium to increase students’ interest and understanding through independent learning.

INTRODUCTION
Learning is an individual process in constructing knowledge to achieve a goal. So learning must be done with a process that is meaningful for each student. Meaningful learning can increase the understanding of each student's concepts. Understanding the concept is very dependent on the conceptions students have about their ideas about the content and meaning of a concept obtained from various information (Wang et al. 2017) (Gunawan et al. 2018). The learning process can provide valuable information for students if the teacher provides a meaningful process for exploring a concept. A good understanding of concepts can be a foundation for students to practice other abilities needed for an individual.
Meaningful learning to be able to improve students' understanding of concepts must make students as the center of learning. In addition to meaningful learning, learning should be done effectively and fun. Effective and fun learning can be supported by teaching materials used in learning (Afifah & Ellianawati 2019). Teachers must plan the learning process well, in order to achieve the goal of understanding students with the material to be conveyed (Afifah & Ellianawati 2019).
Teaching materials that are able to guide students to find their knowledge without continuing to ask the instructor are worksheets (Yulkifli et al. 2019). Stages in the worksheet students must follow the flow. It is used to find their concepts. Worksheets make the learning process interesting and can guide students to construct their knowledge following the expected competencies (Asmawati 2015) (Astusi & Setiawan 2013). Proper steps in the worksheet will be able to guide students to achieve the competencies that teachers expect. So worksheets must be arranged based on teaching material, expected competencies, and conditions of students.
Currently, learning innovations are widely used for the realization of increasing students' abilities towards 21st-century abilities. One that is in the spotlight is STEM (Science, Technology, Engineering, and Mathematics). The STEM learning is learning that is more connected and relevant, able to develop ideas that are constructive and reflective so that it is not just memorizing concepts, but rather on understanding the concepts of science and relationships in life to realize better the importance of protecting the environment (Sthohlmann, Moore, & Roehrig 2012; Afriana, Permanasari, & Fitriani 2016;Pertiwi, Abdurrahman, & Rosidin 2017;Dewi 2017). The development of technology requires the current generation of more literate technology to make it not only as a user. With STEM learning, students can understand the concept of the material to apply it in the manufacture of technology products. Then the physics teacher candidates should consider mastery technology as a means to provide better physics teaching (Muliyati et al. 2019) and need to be equipped with the application of STEM learning so that students who are taught are able to implement the knowledge they can participate in class to solve problems in life.
Improving the quality of teaching and learning outcomes in STEM learning can be done by choosing the right learning approach. It offers a way to help students achieve the required mastery by maximizing class time dedicated to problem-solving and deep conceptual understanding (Bazelais & Doleck 2018). The conceptual knowledge is the understand the core principles and relating them. There are two critical aspects of instructional practices that help students develop conceptual understanding: allowing students to struggle with problems, and discussing conceptual relationships explicitly (O'Dwyer et al. 2015).
Mastery of concepts and technological knowledge possessed by someone is needed by each region, especially the area where he lives. The wealth of an area can be developed if the young generation is willing to preserve and introduce it outside the region. For this reason, in learning, it is necessary to link regional local wisdom to be raised so that it is better known. Local wisdom is the knowledge that comes from experience and local wisdom. Local wisdom is found in the community (Nurdiansah et al. 2018). Local wisdom is the knowledge that has been proven valid in context and locally accumulated by local communities community (Nurdiansah et al. 2018). Linking wisdom by raising the problem of local wisdom can make students able to think openly to explore local wisdom in their area. Introducing local wisdom to students can also increase student awareness in understanding more about the area where they live. The local wisdom values integration in learning strategies enhance the students' positive character (Parwati et al. 2017). Based on the observations of Jufrida et al., students have an interest if the learning material is integrated with the local wisdom of the area (Jufrida et al. 2019).
Local wisdom of an area wrapped with technology can increase students' understanding of the concept of a concept or material. A good understanding of concepts can require students to create a work of technology that can answer problems around their lives so that the formation of students' knowledge of a concept must be started and arranged themselves. So that understanding is stored long in their memory to be developed into more in-depth knowledge.
Material temperature and heat are closely related to daily life, so students must master well to be able to solve problems in their lives related to the material. Much potential can be developed from temperature and heat to become a technology product. So that the need for motivation and good guidance to shape the conception of students to fit the conceptions of the experts.
Based on these backgrounds, a local wisdom-based STEM Worksheet is needed to be used as an alternative in increasing the understanding of the concept of prospective physics teachers on temperature and heat.

METHODS
This study use research and development methods, which are generally known as Research and Development (R&D). This study uses the ADDIE development model (Analyze, Design, Development, Implementation, Evaluation) (Branch 2009). The steps of development research undertaken to develop this local wisdom-based STEM worksheet are as follows.

Analysis Phase ( Analyze )
At this stage, an analysis of the needs of the STEM worksheet based on local wisdom is needed to obtain data about the needs of this worksheet. The number of core respondents is 60 students. Obtained results 87% of students need this worksheet. Then a literature analysis was conducted on the development of worksheets, such as the results of this study.

Stage Design ( Design )
At this stage, the worksheet design is done through literature study, material analysis, media analysis, and guidance with experts. So that from this stage, the stages produced in the worksheet and local wisdom presented in the worksheet.

Development Phase (Development)
At this stage of development, the worksheets were developed following the STEM approach and then linked to the local wisdom of the inner Baduy community in Banten. Then the development that has been done is guided and validated by experts. Validation is done by media experts, material experts, and learning experts. The completion of worksheets was carried out in accordance with expert input.

Implementation Phase (Implementation)
At this stage, a trial was conducted on students regarding this local wisdom-based STEM worksheet. From implementation, the increase of students' understanding of the concept seen.

Stage Evaluation (Evaluation)
At this stage, the worksheet is improved based on the results of the implementation that has been done. This is done to improve worksheets in order to achieve the expected goals and motivate students to learn.

RESULT AND DISCUSSION
The first meeting was given a pretest question to see the level of understanding of students' concepts before learning. After that, the second meeting of the students was given a worksheet that presented problems to motivate them to learn to find solutions to the problems by integrating STEM. After introductory learning is given, students try to solve problems with the guidance of worksheets. The lecturer becomes their facilitator if there is filling out a worksheet that is not well understood. Then at the next meeting, students test and make the tools they have designed to solve the problem at the previous meeting. Here students do practical work to test the success of the tools they make. The fourth meeting of each group presented the results of the tools they made and how they worked together with their development plans. In this meeting, the lecturer confirmed the concepts that had been expressed by the students. Here the conception of students is equated with the conception of physicists. So that if there is a misconception, it can be corrected. The fifth meeting is a posttest activity to test students' understanding of concepts after learning. By using the pretest, evaluation questions can be seen changes in the understanding of student concepts. Worksheets are created to guide students in exploring concepts. So the lecturer or instructor does not do much lecture method. By figuring out their knowledge, it is hoped that the knowledge obtained by students can last longer. Discussion with a group of friends is also expected to improve the socialization of new students for the better.
Worksheets that are made present a narrative story that illustrates the circumstances surrounding students who can introduce local wisdom. The local wisdom is brought to be explored by the potential students after the story is presented, several questions that can explore the problems that can be fixed in the area. Through several questions, students are expected to find the best solution in exploring the natural potential in their area and solving problems through STEM integration expected by the lecturer or instructor. Through the questions, students are also asked to mention and formulate what technology they can make to solve the problem.

FIGURE 1. Presentation of Problems in a Worksheet
Through open-ended questions, students can explore their knowledge, which at the same time also trains high-level thinking skills. As stated by Miliken and Adams in Halim (2012), the STEM approach can train students to apply and integrate the concepts of science, technology, engineering, and mathematics to solve problems creatively and innovatively. Ejiwale (2012) also stated that the application of STEM was able to increase the mastery of knowledge and also apply it in problemsolving. e-Jurnal: http://doi.org/10.21009/1 After leading students' opinions to solve problems with STEM integration, students are led to make mini proposals in worksheets. The purpose of the mini proposal is a proposed plan that will be developed by students.
The second worksheet is a tool testing worksheet. Worksheets only contain questions about how students design experiments to test the tools they make so that they can think more openly without the details of the stages of activities that are usually present in practical instructions.
Observation tables are also students themselves who make with short instructions from worksheets. These brief instructions conclude the steps of product testing, observation tables, graphs obtained to the conclusions of the experiment. After that, in the worksheet, ask students to make a report on the technology tools they made and present them at the next meeting. This worksheet testing is carried out during basic physics lecture hours. This study was conducted four times, each with two credits (2 x 50 minutes). Pretests are given at the first meeting to measure students' initial conceptual understanding. H acyl pretest can be used as a reference to see the level of understanding of the concept of beginning students on the topic of temperature and heat for pretest running well and smoothly.
In the second meeting, the participants were given a presentation on the material temperature and heat as a provision for students to make products that apply this material. Explanation of temperature and heat material starts from the notion of temperature, thermometric properties, how to make and calibrate thermometers, expansion, heat, to heat transfersubmission of material using PowerPoint media, whiteboards, and markers.
At the second meeting, the students were given a STEM-based worksheet to guide students discussing with a group of friends about the application of temperature and heat material to be better understood. The worksheet starts from the presentation of natural phenomena that become local wisdom in Banten, then presents data on natural resources that are not yet utilized by humans. From there, they find their problems by connecting problems in the Baduy area of Banten with natural resources that are still rarely utilized. From these problems, each group discusses to produce a product that can be a solution to the problem that they revealed previously connected with the material temperature and heat. Each group plans to make a different product as a solution to solve the problem. After that, students are asked to work on making their products outside of class hours for one week.  The third meeting of each group presented the results of the products they made. They explained the difficulties in making products, how the products work, to the advantages and disadvantages of the product. Then in the question and answer session, the other groups of students asked questions to enter how the product should be repaired. After the process of preparing all the components on the worksheet STEM local wisdom based on the material's temperature and heat for student-teacher candidates, Physics completely developed, then validated products. The development of local wisdom-based STEM worksheets has been verified in terms of material and media.
Subject matter experts provide ratings on MFIs STEM based on local wisdom is already meet the criteria are eligible with a percentage of 86.4 % with a very decent interpretation on aspects of the e-Jurnal: http://doi.org/10.21009/1 suitability of content and language aspects. In contrast, the interpretation deserves to aspects of the presentation of the material order.
The results validate the feasibility of MFI STEM based on local wisdom by media experts shows the average percentage of 87 % with inter achievement feasible.

CONCLUSION
Based on the results, it can be concluded that the worksheet STEM local wisdom based on the material temperature and cal or for student candidates Physics teacher-developed earn a percentage Sebes ar 86% by subject matter experts and 87% on a media expert. With the popularity scale feasibility stated that the worksheet STEM local wisdom based on the material temperature and cal or for student candidates Physics teacher developed a decent into learning media to increase interest and understanding of students through independent study. We recommend that products created by students be evaluated and improved to get the maximum product.


Brief Discussion on the Influence of Value Guidance on the Construction of Learning Atmosphere in Higher Vocational Colleges

Values are the endogenous power which affects one's development, only from the student's ideology, value pursuit Etc., can really let the student truly be willing to learn, and even love learning and study diligently. This paper attempts to guide students to understand college life correctly from the university spirit, to guide students to understand their own major correctly from the craftsman spirit, and then to form professional identity, to guide students to understand the importance of being a man, doing things and cultivating one's moral character from ideological and moral education. "The prosperity and strength of a country and a nation is not determined by the temporary economic prosperity, but by the values of a country and a nation, that is, the value orientation." [1] General Secretary Xi Jinping said, "when the youth prosper, the country prosper; when the youth flourishes, the country flourishes. If the younger generation has ideals, skills and responsibilities, the country will have a future and the nation will have hope." Contemporary college students shoulder the historical mission of the great rejuvenation of the Chinese nation, whose value orientation is related to the future and destiny of the country and the nation. Universities are not meant to produce sophisticated egoists with a single skill , but the talented person with feelings and warmth who can illustrate illustrious virtue, renovate the people and rest in the highest excellence. [2] Our universities should not only "Spread the truth, teach learning, answer difficult questions", but also build values and cultivate personalities. Values is one of the development of endogenous power, leading the contemporary college students to form correct values and value pursuit is the advance work of doing all school work well, only from endogenous factors such as student's thought concept, value pursuit, can really let the student truly be willing to learn, and even love learning and study diligently. As a whole, there is a gap between the Learning Atmosphere of higher vocational colleges and that in undergraduate colleges. It is related to the enrollment expansion of Chinese colleges and universities and the admission methods of colleges and universities, as well as the quality of our students. At present, students in higher vocational colleges have weak consciousness of self-development, lack of self-management ability and muddling through their lives, it is usually manifested as being late for class or absent from class, or playing mobile phones, sleeping and chatting in class, cheating in exams also happens from time to time, for the majority of vocational students, online games, dating, part-time jobs outside school, etc. occupy most of the time, learning this main business has almost become a sideline. [3] Without a clear sense of self, there is no clear goal and planning, it is also difficult to be positive in learning. "Why come to college?""Why did you choose this major?""What kind of work do you want to do after graduation?" When students are asked such questions, most of them give unsatisfactory answers, "Parents want me to get a diploma.""If you don't study, you can't go out into the society now.""Parents asked me to choose.""My parents have arranged my future job.""Let's wait until after graduation. It's too early to think." It is obvious that most students do not take the time to seriously think about and plan their personal growth, whether it is a short-term or long-term career plan, or even think about what college means to them. Therefore, it is worth thinking about the influence on students' ideological values from the perspective of value guidance in order to change students' learning from internal causes.

Guide Students to Have a Correct Cognition of College Life with University Spirit
"I feel like I've been to a 'fake' university," the student said. "College life is not as free and easy as I thought." The relaxed freedom of not studying and doing nothing has never been the value of the existence and significance of The Times of university. Universities and colleges are responsible for the five functions of knowledge transmission, scientific research, social service, cultural inheritance and international exchange and cooperation. There is no university or college that does not shoulder the mission of cultivating talents, inheriting culture and providing valuable scientific knowledge for society. Universities and colleges in China should train qualified builders and successors for the cause of socialism with Chinese characteristics, this idea should be the internal psychological elements of every college student, in particular, our higher vocational students should find the right position, establish the goal under the guidance of university spirit, understand the responsibility on their shoulders, and understand the era responsibility of Chinese college students in the new era.
As we all know, famous universities at home and abroad have their own university spirit to guide the development of the University, such as "pursuing truth" and "making you a better self" in the spirit of Harvard University, such as "building our country" and "seeking truth and innovation" in the spirit of Zhejiang University. [4] Learning is to pursue truth, to strive for self-improvement, to forge ahead for national rejuvenation, which is a mission education as well as a responsibility education. From the macro level, learning is for the country, the nation and the society; from the micro level, learning is for the family, the family and themselves; from the external power, learning is the need of the national social development; from the internal power, learning is the need of personal self-improvement and self survival. People should be responsible, have motivation, and understand why they learn. Learning is the pursuit of the truth, and it is an effort to make progress for the self, and it is to make progress for the national rejuvenation of the nation. It is a mission education, also a responsibility education. From the macro level, learning is for the country, nation and society. From the micro level, learning is for the family, relatives and themselves. From the perspective of external motivation, learning is the need of national social development, while from the perspective of internal motivation, learning is the need of individual self-improvement and self-survival. People should be responsible, but also have motivation, and understand why they learn.

Cultivating Students' Professional Identity with the Spirit of Craftsman
Many of my students are saying, "I don't think it's useful to study e-commerce. I don't know what I can do in the future." In reality, students in higher vocational colleges do not have a strong sense of personal identity for their major Especially the higher vocational students of liberal arts are more obviously not interested in their own major. Students usually feel that their professional skills are not strong. Operational is not strong. It is difficult to have a skill. Whether students choose their major passively or actively, most students' enthusiasm and motivation for learning in school are easily influenced by external environment, such as professional employment prospects, teacher teaching level, school rankings, personal reasons and so on. For example, the school of our business kind basically give priority to with the major such as electronic commerce, logistics management, market sale, the student feels in actual operation is few, and even have a student to say: "teacher, I learned now later stem sale, I go out now also stem sale, that I study still have what use?" The talents cultivated by higher vocational education are high-quality professionals who can engage in compound skills at the frontline grassroots level. Therefore, our specialization and professionalization are strong, especially in the personal professional field, we need to be more in-depth, meticulous and constantly pursue. Just as "craftsman spirit" is the spirit of pursuit of perfection, its core connotation lies in not only taking work as a tool to earn money and make a living, but also in establishing an attitude of reverence for career, dedication to work, and responsibility for products, paying great attention to details, and constantly pursuing perfection . [5] It can be seen that to cultivate students' professional identity, we have to start from a deep understanding of this major and the industry it belongs to. As the saying goes, "do one job, love one job", we have to start from "drill", so that we can work hard in "research" and have the effect of "essence".

Guide Students' Moral Cultivation by Ideological and Moral Education
General Secretary Xi Jinping said, "we should continue to strengthen moral education and cultivate peoples the central link, carry out ideological and political work throughout the whole process of education and teaching, realize whole-process and all-round education, and strive to open up a new situation in the development of higher education in China." The fundamental task of education and the responsibility of The Times is to cultivate people with morality, and the fundamental task of our students is to cultivate themselves with morality. "Virtue is the overall arrangement of talent, and talent is the capital of virtue."Mozi said, "A man of good moral accomplishment and ability is bound to achieve great things. On the contrary, even achievements are small."Strengthen moral education and cultivate people is to guide young students to understand the big morality, keep public morality, strict private morality.
Patriotism, dedication, integrity and friendship are the requirements of socialist core values on the individual level. They are also the summary of the basic moral norms of socialist citizens, such as "patriotism and law-abiding, honesty and sincerity, unity and friendship, diligence and frugality, civility, integrity, unity and friendship, diligence, frugality, self-improvement, dedication and devotion", they are also the yardstick of our behavior for each of us to live in the world. The basic qualities of young students, such as family and country feelings, fighting spirit and integrity, are shaped and cultivated in the process of learning. Under the background of information age, the influence of multi-culture and the emergence of negative information on the Internet lead to the dislocation of values and ideals and beliefs of many students. A common phenomenon is that students play mobile phones in class, after class, during meals, and before sleep. They spend most of their time playing mobile phones. In such a case, it is only the guidance of teachers in the ideological and political theory course and the educational preaching of counselors that can hardly guarantee the educational effect of students in terms of breadth and depth. Therefore, it is necessary for all staff in universities and colleges to participate in the ideological and political education of students and realize it in the whole process.
As adults, College students have the ability to think and judge independently, and they must have a clear understanding and discrimination of the factors that affect their development, especially in the case of various external circumstances that have a greater impact, so external Guidance and shaping becomes even more important. Value guidance is to help students to have a correct understanding and attitude to themselves, to study and life in the university through the efforts of external means such as teachers, teaching assistants and school atmosphere, this creates an endogenous drive to change and progress.

INTRODUCTION
The educational institution is regarded as an institution creating a developed and advanced youth generation where they can survive in the real-life through education. With the assistance of education, every individual wants to move forward and finishes the education, the individual may earn a decent job and comfortable life. The definition of education itself is explained completely in the constitution number 20 of 2003 on National Education which states that "Education is a conscious and planned effort to create a learning atmosphere and learning process in order the student can develop . THE EFFECT OF ONLINE LEARNING SYSTEM DURING THE COVID-19 PANDEMIC ON STUDENTS' LEARNING MOTIVATION AND INTEREST IN LEARNING.

This corresponds to Allah's command in the chapter of Al-Baqara verse 45, it says: It means: "And seek help through patience and prayer, and indeed, it is difficult except for the humbly submissive (to Allah)".
Therefore, in dealing with the education field, it is required to strive and earnestly to achieve a purpose where the education objective is more like humanizing humans through various strategies, creativities, or innovations to achieve the expected education. In the education process itself, there is a very noble objective whereby the teacher instills values to the pupil to achieve the educational objectives. Allah the Almighty will ease the way to the heaven for the servant who always seeks knowledge. As the following hadith narrated by Abu Abu Hurairah Ra, the Messenger of Allah says: It means: "Whoever takes the path to seek knowledge, Allah will ease the way to heaven for him". (HR. Muslim) Through the knowledge possessed, Allah will ease them to conduct the good deeds. Meanwhile, good deeds are instrument or medium for a servant of Allah to enter the heaven. "Education is an essential aspect in life, it is an asset to traverse the times successively. Becoming a developed nation is naturally every nation's expectation, it is influenced by education. Education is so much important, thus, the development of education influences the country's progress. And by education, it will crease the good and qualified human resources" Gm Jamaludin, A Rosidah, E Nurbaiti, (2020:132).
The rapid development of information technology in today's globalization era is inevitable in its influence on education. The Global demands that education must always and constantly adjust to technological development on the effort of improving education quality, especially in adjusting its usage for education, particularly in the learning process, the development of industrial revolution 4.0 era has given significant influence on learning that must adjust and utilize technology in the era Ghiffar, et.al. (2018). The changes in the demand make education needs innovation and creativity in its learning process. At the beginning of 2020, the world was shocked by the outbreak of the coronavirus from China Budiyanti, (2020).
Indonesia is affected and it becomes a severe problem in the current learning process. Because of the outbreak of coronavirus , there is a policy to dismiss all the educational institution as the effort to contain coronavirus infection Arifudin, (2020). In the Circular of Ministry of Education and Culture Republic Indonesia Number 4 in 2020 on Educational Policy Implementation of Corona Virus Disease (Covid-19) Emergency Period in item 2a, it was mentioned that the learning process from the home through online learning/distance learning is conducted to give a meaningful experience for the student Pusdiklat Kemendikbud RI, (2020).
One of the solutions that can be conducted in the learning process is that distance learning utilizes the existing technology. Currently in Indonesia, the educational institution has applied online learning activity. Online learning is indirect learning without having face to face using internet technology, so that, it is connected from a distance. According to Michael, (2013:27) "Elearning is an arranger learning with the purpose to use an electronic system or also computer, so it can support a learning process". From the explanation, according to Kemenristekdikti team, (2017), it says that online learning is the learning "within a network" as the translation of 'online' term which means connected into the computer network.
The success of an educational process is really influenced by the continuing learning because it is the core of the educational process; in learning, student's motivation to participate learning is a very important aspect. Student's learning interests and motivation are very needed to achieve the learning objective because it is as the influencing factor to the success in learning. According to Djalil, (2013) said that factors influences student's in learning is the existence of internal and external factors. Internal factors such as health, intelligence, interest, motivation, and their way of study. While external factors such as family, school, society, and also the environment.
The first factor is the low motivation to study, giving motivation means the effort to provide situation and condition, so the children will, want to do it. Children with high intelligence, maybe fail in the lesson because of the lack of motivation. The best outcome is achieved with strong motivation. The failing kid is not necessarily to be blamed. It is probably the teacher has not succeeded in evoking motivation to the pupil's activity S. Nasution, (2000).
Hence, the pupil will be motivated in studying if the environment can give the stimulus, so that, the pupil are interested to study. The comprehending and utilizing the class atmosphere well by the pupil is expected can support its success in learning Elida Prayino, (1989). In this case, it is clear that learning also very affecting the student's learning motivation; and the teacher's role is very important to evoke and give motivation to the pupil. Thus, there is a difference in the learning system at the school changes to the family environment. As for the student's characteristics who are motivated, i.e. diligent, resilient in facing hardship, showing interest in various kinds of problems, prefer to work alone, easily to be bored with an assignment, able to defend the argument, fondness to seek and solve problems.
The second factor influencing the low rate of success in studying is learning interest. The learning interest is something from within the student itself influenced by the intention to study. According to Sardiman, (2008: 76) "intention can be interpreted as a condition occurred if a person sees temporary characteristics or meanings that are related to their intentions or needs. The intention existed in a person will describe the activity to achieve the purpose". Learning interest can be said as important in learning activity because it has a great influence on the passion to study. A student who has an interest in a certain subject surely will study the subject earnestly such as diligent in learning, enjoy to follow the subject even though they find difficulties in the study. Conversely, if the student did not have an interest in a certain subject, thus it will be difficult for the student to learn well.
Naturally, this will influence the student's interest in the study.
Based on the data obtained from the headmaster of SMP Plus Hafadata Yusuf Argapura sub-district on 06 July 2020, the learning-teaching activity has not been entirely yet implementing online learning, the medium used still uses photocopy sheet material, the brief explanation makes the student difficult to understand the lesson, and also online learning devices have not been prepared yet. Many students do not have an android mobile phone or smartphone, the unpleasant environment makes the student cannot concentrate on learning, so it makes the student's learning motivation and interest become low. Starting in July, there is a plan to apply online learning, starting on august, it has been implemented online learning in the school.

Online Learning System
Online learning is "within a network" learning as an interpretation of an online term which means it is connected into the computer network Kemenristekdikti Team (2017). "Online learning is the online learning strategy or is conducted within the network" Mustofa, et.al. (2019:11). Online learning is the strategy in learning that is pleasant for the participants because they can listen to it through an android handphone, laptop, or computer, not just from books Sobron A. N, et.al. (2019). Nurhayati, (2020) states that E-learning for the first time was introduced by Illinois University in Urbana-Champaign using a computer-assisted instruction system and a computer named PLATO.
Benny A. Pribadi, (2017:203) said that "learning activity through Elearning can help students to achieve ability or competence required in effective and efficient way. The E-learning user can save time and perform the learning process with more time duration". According to Michael, (2013:27) says that "E-learning is the learning arranged for the purpose to use an electronic system or also computer, so that, it is able to support a learning process". According to Ardiansyah, (2013) in Setiawan, (2020) Elearning is a learning system used as a teaching-learning process carried out without face to face directly between the teacher and the students.

Learning Motivation
According to Sardiman, (2014:75) explained that "learning motivation is the psychic factor that is non-intellectual. The unique role is in growing the passion, enjoying and being enthusiasm to study. Later on, Hamzah B. Uno, (2010:23) mentioned that "the essence of learning motivation is internal and external encouragement to the students who are studying to make changes in behavior, commonly with some indicators or supporting elements. Based on the explanation above, it can be concluded that learning motivation is the encouragement inside a person that can be influenced by an internal or external factor, that will encourage a person to conduct a learning activity to achieve a certain objective. This learning motivation will direct the person during studying activities.

Learning Interest
Interest is one of the main factors to achieve success in every field, either in the study, work, hobby, or any other activities. This is because there is increasing interest within a person that will create attention to perform something diligently and in the long term, more concentrating, easy to remember, and not easily to get bored. Interest is a psychological factor that everybody has. Thus, interest in something/certain activity that can be owned by everybody. If a person is interested in something, an interest will emerge.
According to Sardiman, (2014:76) interest can be defined as a condition occurred if a person sees the temporary characteristics or meanings that are associated with his intentions or needs. The interest in a person will describe the activity to achieve the purpose. Crow and Crow in Djaali, (2013) say that interest is related to the force of motion to deal with or try with someone, object, activity, experience that is stimulated by its activity. Learning intention is one of the forms of one's activeness that is encouraged to perform a set of physical or mental activity to obtain a change in behavior as the result of individual experience in the environment related to cognitive, affective, and psychomotor.
The covid-19 pandemic condition requires all students to study at home using an online learning medium prepared by the school. The learning benefit during the current Covid-19 pandemic is that the student has much spare time at home, save transportation costs, and decrease in traffic jams (Purwanto et al. 2020). Some shortcomings in online learning or at home is the students often feel bored, this condition is caused by the student is alone or doing a monotone activity at home, besides boring on online learning also decreasing student's learning motivation, increasing electricity and internet cost (Nurhasanah, 2016). The result is caused by learning at home or online decreases the student's learning interest and motivation as an impact of the continuing bored student condition at home (Siagian, 2015).
During the pandemic period, the learning process is expected to continue as planned, for the learning to keep on going, so it makes policy to study at home. The students have problems when the teacher gave the assignment. During making the assignment, they seem to play a lot. The game and such kind of it mostly disrupts the student, so that, the many assignments were completed or they did it (Setyorini, 2020). One of the schools that is succeeded in online learning is Integrated Islamic Elementary School (SD IT) Rabi Radhiyya Curup. The evaluation result conducted shows the learning process run as planned and the target. Some of the learning activities on building characters are tahfidz, tahsin, memorizing hadith and prayer, and other activities also run well, so does the assignment given by the teacher to be done at home as planned (Sutarto et al. 2020). The researchers have already conducted a study on learning strategy. Most of the researchers are studying on face to face or offline learning strategies in normal conditions.
The result of their research shows that there is an influence on student's learning outcomes with learning strategy (Hattie, 2016;Nasution, 2018;Solihatin & Syahrial, 2019).

METHOD
The research method used in this study is the quantitative approach.
According to Sugiyono, (2019:16) he says that the quantitative research method is because the data research is in the form of numbers and the analysis uses statistics. The design of the study uses Quasi-Experimental Design, the research design used is Nonequivalent Control Group Design.
Whereas the experiment or control group is not selected randomly. The experiment and control group are conducted with the initial test. The two groups get different treatment, whereas the experiment group uses online learning, and the control group uses offline learning and ends with a final test for each group. The population in this research are class VII students in SMP Hafadata Yusuf Argapura sub-district consisted of 29 students. The sample used in the study is a saturated sample, whereas all of the populations were used as a sample. The sample used in the study is the entire students in class VII which are divided into two groups, those are experiment class group, and control class group.

RESULT DAN DISCUSSION
T-test aims to find out whether there is a significant difference between the result of the experiment class and the control class. Thus, the research uses the independent samples T-test model, with the following criteria: If the Prob value/Significance/P-value < α so H0 is rejected If the Prob value/Significance/P-value ≥ α so H0 is received Table 2 Independent Sampel Test Based on the test result on the above table, it is obtained F value, assumes that the both same variants are 0.545 with t value = 9.464 with independent degree (df) of = n1 + n2 -2 = (14 + 15 -2 = 27). α = 0.05 it is  learning motivation between students in the experiment class, which was given online learning treatment and the control class which did not use online learning. This shows that using an online learning system can influence the student's learning motivation compared to the class which did not use online learning.
