The Effectiveness Of Using Cooperative Learning Model From Broken Triangle, Square, Heart Type Towards The Students’ Cognitive Learning Outcome

Abstract

This research aims to know the effectiveness of using cooperative learning model from broken triangel/square/heart type to the students’ cognitive learning outcomes. The research used quasy eksperimental design particularly nonequivalent control group design. The population was 40 students from Class III SDN 5 Tengadak. Nonprobability sampling was used as the sampling technique covering the design of saturated sampling. The data were collected through direct observation (observation sheets), measurement (test sheets) and indirect communication (questionnaire). The result of observations obtained 100% fulfillment for teachers and students’ participation. From the analysis, it was found that cooperative learning used had high effectiveness on students’ cognitive learning outcome or scored 0,87 as could be seen from the effect size which stated that if ES>0.8 then the category was high. In addition, the result of hypothesis testing on the posttest from experimental class and control class were 2.988 for tcount and 2.024 for ttable at a significant level 0.05 which meant that tcount>ttabel (2,988>,024).The questionnaire result showed 100% fulfillment from teacher and students’ participation. In conclusion, there were significant differences of students’ cognitive learning outcome between the experimental class and the control
