PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE THINK TALK WRITE TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA

Abstract

This research aims to (1) know the difference in student’s mathematical problem solving abilities between classes  using cooperative learning model Think Talk Write type with classes using conventional learning model and (2)  know the contribution/influence of cooperative learning model Think Talk Write type on the mathematical problem solving abilities. Type of research used was research of quasi experimental with research design used posttest only control design. The subject was taken used Purposive Sampling, was obtained class VIII G as the experimental class and VIII F as the control class. The Instrument used in this study was posttest in term of questions on the subject matter of number pattern and number sequence, observation sheet on the learning process, and the plan of implementation of learning. The data analysis used was two independent sample t test and effect size to found out the influence of cooperative learning model Think Talk Write type on the mathematical problem solving abilities on the subject matter number pattern and number sequence VIII grade students of SMP Negeri 8 Mataram. The results showed that there were differences in student’s mathematical problem solving abilities between classes  using cooperative learning model Think Talk Write type with classes using conventional learning model. The contribution of cooperative learning model Think Talk Write type to student’s mathematical problem solving abilities was in the medium category. It means that cooperative learning model Think Talk Write type has a positive influence on the mathematical problem solving abilities on the subject matter number pattern and number sequence VIII grade students of SMP Negeri 8 Mataram
