The Comparison of Student Learning Outcomes Using Make a Match and Snowball Throwing Model Learning on Ecosystem Materials in Class X SMA Yayasan Perguruan Keluarga Pematangsiantar Academic Year 2019/2020

In the teaching and learning process there are interactions or reciprocal relationships between students and teachers, where students receive lessons taught by the teacher. According to Slameto (2003: 2) "Learning is essentially a business process undertaken by someone to obtain changes in new behavior in a way overall, as a result of his own experience in his interactions with the environment". The teacher teaches by stimulating, guiding students and directing students to learn lesson material according to the objectives to be achieved. Biology is one of the subjects contained in a series of learning activities. In studying Biology many students are found to be bored and fed up with subject matter taught because biology is memorized. Many ways that teachers do to teach students, ranging from using several learning models. According to Skinner in Isriani and Dewi (2017: 4) states that learning is a process of adaptation or behavior adjustment that takes place progressively. Abstract

The teacher's goal is to do a lot of models in learning in order to achieve the desired competencies. Specifically in biology subjects that have a lot of memorization or information that is memorized in the minds of students. In the 2013 curriculum as it has been implemented in SMA Yayasan Perguruan Keluarga Pematangsiantar, teachers are no longer only teach with conventional methods but teachers are required to be able to apply various learning models so that students can easily and not get bored in learning biology.
Biology teacher in SMA Yayasan Perguruan Keluarga Pematangsiantar has implemented several learning models such as discussion, memorization, and lecture models. So that students do not play an active role in learning, the learning model results in a 65% student score fulfilling the Minimum Mastery Criteria where the Minimum Mastery Criteria is 65. In addition, it is also known that the average score of From the results of observations made by the writer with biology teacher of SMA Yayasan Perguruan Keluarga Pematangsiantar, every year students who excel in biology take a City and Provincial Science Olympiad but never win a champion. Therefore it is necessary to develop learning that can increase student learning activities. One effort to improve student learning activities is to choose the right teaching method.
One of the learning models that can be expected to achieve the above objectives is that interesting learning needs to be tried to apply a learning model that can arouse student learning motivation, so as to improve student learning outcomes. The learning model that will be used is the Make A Match and Snowball Throwing learning model.
According to Istarani (2011) Make A Match is an alternative that can be applied to students. The application of this model starts from the technique that students are told to look for pairs of cards which are answers / questions before the deadline, students who can match the cards are given points. One of the advantages of this technique is that students look for partners while learning about a concept or topic in a pleasant atmosphere.
According Istarani (2011) Snowball Throwing is a series of presentation of teaching material that begins with the delivery of material, then forms groups and group leaders who then each group leader returns to their respective groups, then explains the material delivered by the teacher to his friend and students are given one sheet of paper, to write down any questions regarding the material that has been explained by the group leader.
From the observations, the writer found that the teacher had never done the Make A Match and Snowball Throwing models. The Make A Match and Snowball Throwing learning model is very different from the conventional learning model conducted by teachers in schools. This difference can be seen from the syntax and methods used in the learning process.
Based on the description above, the authors conducted a study with the title: " The Comparison of Student Learning Outcomes Using Make a Match and Snowball Throwing Model Learning on Ecosystem Materials in Class X SMA Yayasan Perguruan Keluarga Pematangsiantar Academic Year 2019/2020".

Location and Time
This research was conducted in class X in SMA Yayasan Perguruan Keluarga Pematangsiantar Seram Street No.15, Pematangsiantar in March 2019/2020 Academic Year.

Population and Samples
a. The population taken in this study were all students of class X MS in SMA Yayasan Perguruan Keluarga Pematangsiantar consisting of 3 classes with a total of 103 people. b. The sample taken in the study is by Cluser Random Sampling, which is random sampling. So that the chosen class X MS 1 and X MS 2 where both classes as the Experiment class (treated), each class totaling 34 students.

Research Design
This type of research is an experimental study using quasi-experiments, namely Quasi Experiments. The sample in this study was grouped into two classes namely X MS 1 (experimental class I) was to use the Make a Match learning model and class X MS 2 (experimental class II) was a Snowball Throwing learning model. Before learning began, both sample classes were given Pre-test to determine the initial abilities of students.
Then the experimental class I was taught using the Make a Match learning model and in experimental class II was taught using the Snowball Throwing learning model, then after the lesson was given a Post-test to find out the learning outcomes of each sample class.

Research Instruments
The data needed in this study is the data from the written test results which are student learning outcomes in the Ecosystem material in Experiment I class namely X class 1 MS and Experiment II class X class MS 2, the instrument used in collecting the data is the learning achievement test in the form of Pre-Test and Post-Test as follows: a. Measuring instruments in the form of items in the form of multiple choice with 4 kinds of answer choices (a, b, c, and d) with a total of 20 questions. b. Each correct score is given a score of 1 and a wrong score is given 0. With the following formula: N = true number x 100 Number of questions

Research Procedure
The research procedure consisted of three stages: a. Preparation phase -Arrange research schedules. c. Final Stage -Analyze data.
-Draw a conclusion -Make a research report.

Data Analysis Techniques a. Normality Test
Normality test is calculated using SPSS 21, used to determine whether the research data is normally distributed or not. According to Sudjana (2016: 249) can be calculated using the formula Chi squared (X 2 ):

b. Homogeneity Test
Homogeneity test is used to see whether the two classes tested have the same variance or not. According to Sudjana (2016: 250), homogeneity can be calculated using the formula: With the decision making criteria that is sig>.05, it can be said that the variance is the same and if sig<0.05, it can be said that the variance is not the same.

c. Calculating Averages
To calculate the average (͞ x) using SPSS 21. According to Sudjana (2016: 67) to calculate the average value, the formula can be used: Information :

e. Test the Research Hypothesis
To test the hypothesis whether the truth can be accepted or rejected, a t-test with a significant level of α = 0.05 is used. According to Sudjana (2016: 239), hypothesis testing can be calculated using the formula: Where S 2 is the combined variance calculated by the formula: Information : t = coefficient sought X͞ 1 = The average value of Experiment I class X͞ 2 = Average grade of Experiment II class S = Standard deviation S 2 = Standard deviation combined S1 2 = Standard deviation of Experiment I class S2 2 = Standard deviation of Experiment II class n1 = Number of sample for Experiment I class n2 = Number of sample for Experiment II class With testing criteria: a. If tcount <ttable, at a significant level α = 0.05 and degrees of freedom (dk) = (n1 + n2) -2, then H0 is accepted and Ha is rejected, meaning there is no difference in student learning outcomes using the Make a Match and Snowball learning model.
