Pengaruh Model Pembelajaran Kooperatif Tipe Two Stay Two Stray Terhadap Pemahaman Konsep Matematis Siswa Kelas V SDN Cijambe

Abstract

This research is motivated by the low understanding of students' mathematical concepts, seen from the data on student learning outcomes, most of the student scores are still below KKM. The purpose of this study was to determine the effect of using the Two Stay Two Stray cooperative learning model on students' ability to understand mathematical concepts. The research method used in this research is a quasi-experimental design nonequivalent control group. The samples taken were 29 VA class students as the experimental class and 29 VB class students as the control class. Before being given treatment, the experimental class obtained an average pretest value of 40.52 and the control class obtained an average value of 41.38. In the final stage, the researcher gave a posttest to students in the form of test sheets for students' ability to understand mathematical concepts. In the experimental class, the average value of the posttest was 82.42 and that of the control class was 71.14. Then a hypothesis test was carried out which obtained a significance value of 0.000 <0.05, which means H₀ rejected and H₁ accepted. This shows that there is an influence from the use of the Two Stay Two Stray cooperative learning model on students' ability to understand mathematical concepts by 77.97%. Based on these data, it can be concluded that there is an influence from the use of the Two Stay Two Stray cooperative learning model on students' ability to understand mathematical concepts
