DIFFERENCES IN MATHEMATICS PROBLEMS SOLVING STUDENTS WITH IMPLEMENTING LEARNING MODEL THINK PAIR SQUARE AND GROUP INVESTIGATION IN JUNIOR HIGH SCHOOL

Think Pair Square and Group Investigation are models cooperative learning to used teach students to active in learning. Cooperative learning model gives students the chance to work together with other students to improve problems solving skills. The purpose of this study is to test difference in mathematical problem solving ability of students taught by cooperative learning and the interaction between models learning towards problem solving abilities. This study is a quasi-experimental research using two classes experiment. The research subject is determined based on random sampling class and measurement instruments using essay test. The results of measurements of problem solving ability in the form of data and analysis varians two path. Base on the data analysis, average varians the differen problem solving ability students with Fcount=13.105, and the interaction between learning model towards problem solving ability with Fcount=5.774. The results of analysis varians shows that the values problem solving ability and the interaction learning models between toward problem solving ability more than 4.001. this means that H0 refused and H1 accepted so that there is the differen problem solving ability and interaction between learning models toword problem solving ability taught cooperatives learning think pair square and group investigation.
