The Effect of Cooperative Learning Models and Logical Thinking Ability to The Result of Learning Mathematics of Grade Eight Students

摘要

This study was aimed at finding out the effect of cooperative learning models and logical thinking ability to the result of learning mathematics. This study used a quasi-experimental research design. The populations consisted of 144 grade eight students in Trisakti 1 Junior High School Medan. The sample consisted of 72 students that were divided into two groups. The instruments used were mathematic test and logical thinking ability questionnaire. The data which analyzed in this research was the value of mathematics learning outcomes from cognitive domain. The data was analyzed using Two-Way technique: analysis of variance (ANOVA). The result of the research are as follow: (1) The difference in the results of learning mathematics between student who are taught by Jigsaw cooperative learning model and the results of learning mathematics students who are taught by STAD cooperative learning model, (2) The difference in the results of learning mathematics between students who have high logical ability (HL) and low logical thinking ability (LL), (3) the interaction between cooperative learning models and the logical thinking ability on mathematics learning outcomes.
