STUDENT TEAM TYPE COOPERATIVE LEARNING APPROACH ACHIEVEMENT DIVISION TO IMPROVE REASONING ABILITY MATHEMATICAL
Abstract
This research aims to find out whether the improvement in mathematical
reasoning abilities of students who use Student Team Achievement Division (STAD) type
cooperative learning is better than students who use conventional learning. The research
method used was quasi-experimental with the Nonequivalent Pretest-Posttest Control
Group Design type. The population in this study were all students at SMP Negeri 3
Subang, with a sample of class VIII I as the experimental class of 33 students and class
VIII G as the control class of 34 students. The instruments used consisted of a pretestposttest test and a Likert scale to measure student learning motivation. Data were
analyzed using IBM SPSS Statistics 26.0 For Windows software. The results of the
analysis with a significance level of 5% using the t-test show that the increase in
mathematical reasoning abilities of students who receive STAD type cooperative learning
is significantly better than students who receive conventional learning (sig. 2-tailed 0.002 <
0.05) meaning H0 = rejected H1 = accepted. This indicates that students have a positive
influence on STAD type cooperative learning, thus can be used as an alternative in
mathematics learning to improve students' mathematical reasoning abilities.
