IMPLEMENTATION OF THE COOPERATIVE LEARNING MODEL TYPE TWO STAY TWO STRAY TO UPGRADE SCIENCE LEARNING OUTCOMES

Science lessons are subjects that make us think and reason and be able to solve existing problems. The low scores of students in science subjects are due to the fact that the learning process is still conventional and does not involve students. The solution provided by researchers to overcome this problem is to provide action on the learning process in the form of classroom action research with the Two Stay Two Stray Cooperative Learning Model. This research consisted of two cycles where each cycle started from planning, implementing, observing and reflecting. The Two Stay Two Stray cooperative learning model is a learning that prioritizes student activity and cooperation in finding, answer and report information to small groups cooperatively with the aim of being the first group to complete a set of questions. The purpose of this study is to describe student learning outcomes by applying the Two Stay Two Stray Learning model and to describe the learning process by applying the Two Stay Two Stray Cooperative learning model. This research was conducted from August to September 2022 in class VII-A of SMP Negeri 1 Hiliduho, with 20 students, 6 boys and 14 girls. The results of this study were that student learning outcomes in science lessons increased with the application of the Two Stay Two Stray Cooperative learning model, where at the end of the cycle the average student learning outcomes reached 80, 6 with a learning completeness percentage of 90% and the learning process in science subjects is improved by applying the Type Two Stay Two Stray Cooperative learning model where at the end of the cycle the average result of the observation sheet reaches 84% and has reached the target set at 75%. Thus it can be concluded that student learning outcomes in science lessons increased with the application of the Two Stay Two Stray Cooperative learning model and the learning process in science subjects was improved by the application of the Two Stay Two Stray Cooperative learning model.

One of the objectives of learning mathematics is that students have a good understanding of mathematical concepts. However, students' conceptual understanding is still relatively low. One of the efforts that can be done to improve students' understanding of mathematical concepts is to apply the Two Stay Two Stray type of Cooperative learning model. students who study with conventional learning and describe the development of students' understanding of mathematical concepts during the implementation of the Two Stay Two Stray Cooperative learning model in class XI MIPA SMA Negeri 1 Gunung Tuleh. This type of research is a quasi-experimental with the nonequivalent posttest-only control group design. The population of the study was students of class XI MIPA SMA Negeri 1 Gunung TulehT for the academic year 2022/2023 with class XI MIPA 1 as the experimental class and XI MIPA 2 as the control class. Research data were collected through quizzes and tests of students' mathematical concept understanding abilities. Quiz score data were analyzed based on the average score, as well as the percentage of students' scores per indicator. The test data were analyzed using t-test. Based on the results of data analysis, it can be concluded that in general the development of students' understanding of mathematical concepts has increased while using the TSTS model. Then, based on the results of hypothesis testing, it can be seen that the understanding of mathematical concepts of students who use the TSTS learning model is better than the understanding of mathematical concepts of students who study with conventional learning models. So it can be concluded that there is an influence of the TSTS learning model on the understanding of students' mathematical concepts.
