Abstract

In the application of the STAD learning model, it consists of five steps, namely class presentation, group learning activities, individual tests, determining individual score increases, and group rewards. This study aims to improve the learning outcomes of flat shapes for fourth grade students of SDN 193/V Dusun Mudo in the even semester of 2020/2021. The approach used in this research is a qualitative approach and the type of research is classroom action research. The results of research conducted on 30 students are as follows: in cycle 1 of meeting 1, the learning outcomes of students are 6.8. Actions in the first cycle of the second meeting obtained an average learning outcome of 7.5. In general, the implementation of the first cycle of the second meeting compared to the first cycle of the first meeting was better. The action in the second cycle is to prove that the learning outcomes obtained by students continue to increase and the learning outcomes obtained are 8.3. From the results of the study, it is evident that the use of the STAD model can improve student learning outcomes.

Abstract

This article explains the effectiveness of ethnomathematics-based mathematics modules on students’ critical thinking skills. The research method used is a quantitative method with the type of post-test only control design with a cluster random sampling technique. Data were collected through documentation, observation, and test methods. The instrument used the validity test, the level of difficulty test, the test of discriminating power, and a reliability test. The data analysis technique used an analytical prerequisite and hypothesis tests (t-test). Based on the t-test result between the experimental and the control classes, it was obtained the value of 1.872 while ttable was 1.67. Above it, tcount > ttable, which means that the experimental class average is higher than the control class average. Hence, it can be concluded that the use of ethnomathematics-based mathematics modules on students’ critical thinking skills is better than learning that does not use ethnomathematics-based mathematics modules.
