Cooperative Learning Models Of Learning Effectiveness Tai And Stad Type In Improving Student's Critical Thinking

Abstract

This study aims to determine the level of effectiveness of the cooperative learning model type TAI "Team Assisted Individulization" and type STAD "Student Teams Achievement Divisions" as a learning model in improving the critical thinking of elementary school students of class V in science subjects. This experimental research was in the form of a Quasi Experimental Design. The research design used is a quasi-experimental research using the nonequivalent control group design pattern. This research is an experimental research conducted at SD Negeri Polobogo 03 and SD Negeri Polobogo 02 which are located in Polobogo Village. The research was conducted from February to March in the second semester of the academic year 2021/2022 which was carried out in class V. The samples in this study were obtained through probability sampling techniques with purposive random sampling type. Based on the research results, the effectiveness of the cooperative learning model type TAI "Team Assisted Individulization" showed an average increase of 28.57% greater than the cooperative learning model type STAD "Student Teams Achievement Divisions" which was 26.75%. Based on the results of the research hypothesis test using the mean difference test on the independent sample t-test, it shows that there is a significant difference between the cooperative learning model of the TAI type "Team Assisted Individulization" and the cooperative learning model of the STAD type "Student Teams Achievement Divisions" in terms of ability results. critical thinking of students in science subjects.
