This research which consists of two stages, namely the preliminary study (the preparation stage, the e-Module prototype development stage) and the formative study stage (the evaluation and revision stages). Data collection techniques used in the form of questionnaires and tests, and was analyzed descriptively.


INTRODUCTION
The students were given a sufficient understanding of statistics learning as the statistics are a core course at X to XII in senior high school, especially for the science majors. The research statistics provide good provisions for students to be able to think and do activities carefully, precisely, correctly, using general and clear systematics. The presentation of the research is not subjective, emotional, express conjecture, prejudice and is without facts.
According to Satori and Komariah [5] the research conducted with the scientific method is based on rational, empirical, and systematic scientific characteristics. The research that requires a hypothesis on the problems raised by students is expected to be tested to obtain answers, whether the hypothesis is based on theoretical studies is true or false. Hypothesis testing can be completed if there is sample data which is a representation of the population data. The data obtained from respondents is closely related to sampling techniques. In order to understand this material deeply, the statistics are required.
Winarno Surakhmad [9] states that statistical knowledge cannot be ruled out for a particular discussion for research investigation. Therefore, to support the students' understanding of statistics, they are also required to study the fundamental of statistics courses from junior high school to the first year of senior high school level. Statistics have a role as a tool for analysis and interpretation of quantitative scientific data as the conclusion is drawn from the data. According to Tiro [8] statistics is a scientific way to collect, organize, present and analyze data, and draw valid conclusions to make proper decisions based on its analysis. Thus, it can be said that statistics are used as a means of developing a way of thinking logically. Sigit Nugroho [6] states that the statistics are concerned with the scientific method to collect, organize, summarize, present, analyze data including drawing valid conclusions, and making reasoned decisions based on certain analyzes.
Panen [3] explains that in meaningful teaching theory suggests that the meaning of presentation and the importance of regulating learning progress and advance organizer where teaching materials must be designed properly to be attractive to students. To overcome this problem, the researcher wants to provide alternative solutions to problems, namely by developing independent learning resources in the form of modules that will direct students not to experience difficulties in learning statistics, as well as making learning that is liked by them so that they are more creative and take advantage of the internet/wifi on campus for the process learning. The learning module is one of the independent learning resources for students which is used to facilitate the distribution of learning messages to be conveyed to students and to enable students to study independently. According to Purwanto, et al [4], the purpose of compiling the module is to support to master the competencies taught in learning activities using an electronic module (e-Module).
The researchers want to develop e-modules due to the student's capability to operate electronic devices that can read electronic modules (e-modules) such laptops and smartphones that enable students to study anywhere. With the existence of teaching materials in the form of e-Modules that are integrated directly with the student learning needs, specifically derivative materials that will directly train the teaching and learning system. There are some studies on eModule development by Nurmawati et al [2] that e-module media using the Guided Note Taking model in Mathematics II course is valid and can be used in the learning process. Their research result shows that learning using e-module media using the Guided Note Taking model is better than conventional learning.
The research question for this study is "How is the development of Edmodo e-module statistics teaching materials that have been tested for validity and practicality for 4th-semester students?"

The development of Teaching Materials
The development of teaching materials derived from two words "development" and "teaching materials". According to Sugiono [7] the term development refers to an activity to produce a new tool or method, during which the assessment and improvement of the tool or method are continuously carried out during the activity.
Based on the scope of the teaching material content above, the teaching materials developed are structured and systematic, so that the content of the teaching materials can direct the development of valid, practical teaching materials and have potential effects on students.

E-Modul
According to Azis and Jayanti [1] that emodule is a learning tool that consists of material, methods, limitations and the ways of evaluating which are designed systematically and attractively to achieve the expected competencies in accordance with the level of complexity electronically that is a part of elearning. The objectives of e-module development according to the UT e-Library are: 1. Clarify and facilitate the message presentation to minimize the verbal learning. 2. Overcoming the limitations of time, space and sensory power both students and teachers or instructors. 3. Can be used appropriately and varies, such as to increase the motivation and passion for student learning, to deevelop the student's ability to interact directly with the environment and other learning resources, to develop the independent learning according to their abilities and interests, and to develop the measurement or evaluation of their own learning outcomes.

Research Desain
Referring to the research objectives that have been stated in the introductory section, the research type is development research or Development Research [1]. The e-module development is carried out in two stages, namely the preliminary study stage consists of the preparation and model development stage and the formative study stage consists of the evaluation and revision stages.

Result
This research is a development research or Development Research. The e-module development is carried out in two phases. The first phase is the preliminary study stage consists of the preparation and model development phase and the second phase is the formative study stage consists of the evaluation and revision Material design (prototyping); This stage includes designing the e-module of the statistical material that is assisted by Edmodo and the semester learning plan tools. In this phase, the researcher designed the edmodo e-module tool for research statistics teaching materials, including designing the edmodo e-module in the form of teaching materials, RPP and the student activity student. The process of designing Edmodo e-modules as an assessment instrument was carried out by prototyping that has three characteristics include content, construct, and language. Those characteristics are the focus of the assessment of each prototyping.

Formative Study
This evaluation is using formative that includes these three evaluations below.
(1) Self Evaluation. In this stage, a selfassessment is carried out on the e-module prototype of statistical material assisted by Edmodo. (2) Expert Reviews. In this stage, the e-modile is tested by material, statistical, and IT experts. Meanwhile, the material validation through questionnaires in terms of content, contruction and language is in accordance with the principles and characteristics of online learning. It focusses on clarity, image definition and context suitability though the questionaires. Furthermore, the validation results are revised.
(3) One to one, small group dan field test.

Discussion

The results of the student response questionnaire assessment
The second draft of the learning emodule is practicality will be assessed through limited trials. The practical assessment of the Edmodo e-module in the developed statistics subject was carried out by 5 students in the class of XII at Public Senior High School Number 1 in SP Padang. The assessment is completed by filling out a student response questionnaire consisting of 16 questions. After those students were allowed to study using the second module of emodule Edmodo learning, at the end of the meeting students were given a response questionnaire to see the student's response to the e-module developed.
Based on the table, it shows that the Edmodo e-module for the courses developed meets the minimum practical criteria in all aspects. So, it can be concluded that the Edmodo e-module for statistical learning developed has practical criteria in its use with an average of 72%. Even so, there are comments and suggestions given by students on the second draft of the Edmodo e-module in statistics lectures that students have used. The following are some of the comments given by students, it can be seen from the use of Edmodo online which is very well used, can be uploaded and opened on smartphones and laptop applications. However, it is constrained by students who have the limitation of accessing smartphones or laptops. After obtaining the second draft, a revision was made of the students' practical results in the small group sample test on the small group. The review was carried out to produce the third prototype or the third draft which would be tested in a larger group of students which consisted of one large class.

Field Test
After obtaining a valid and practical third prototype or the third draft, a field test was conducted on the research subject of the school.
This stage is carried out to determine the extent to which the level of success and does not affect student learning that has been taking place using the Edmodo e-module in statistics.
The lectures are conducted for more than two months consisting of face-to-face lectures in class and questions that can be opened through an android application in the form of smartphones and computers which makes it easier for students to study anywhere. After learning several times meetings, the students were given a final test on statistical questions to find out the extent to which students' understanding of learning in statistics for which learning is used the Edmodo e-module application. The research results discover that the average test of all students in one statistical question was good enough in their ability to absorb and work on statistical questions.
From these results, it can be categorized as lecture learning assisted by the Edmodo emodule in this statistical subject which has a good potential effect on student learning outcomes.
