THE EFFECT OF IMPLEMENTATION REASONING AND PROBLEM SOLVING (MP3M) APPLICATION MODEL THROUGH GEOGEBRA TOWARD MATEMATICS PROBLEM SOLVING AND LEARNING MOTIVATION OF VIII STUDENT SMP NEGERI 3 GIANYAR

This study aimed to (1) to investigate whether MP3M through Geogebra had positive effect toward students’s problem-solving and motivation to learn mathematics (2) to investigate whether MP3M through Geogebra had positive effect toward students’s mathematics problem solving (3) to investigate whether MP3M through Geogebra had positive effect on students motivation to learn mathematics. This research was experimental research who implemented post-test only control group design that the population was consisted of 10 classess and chose 2 classess radomly as sample. The experimental research was the implementation of MP3M toward Geogbra which was done for 8 meetings. The data were the mathematical problem solving that was collected with the description test and the student mathematics learning motivation that was collected in the form of a questionnaire. The data were analyzed using Manova test with a significance level of 5%. The experimental result showed that, (1) the ability of students’ problem solving and mathematics learning motivation who was taught by MP3M through Geogebra significantly better rather than the ability of students’ problem-solving and mathematics learning motivation, the ability of  students’ mathematics problem solving, and the students mathematics learning motivation who was taught by the conventional learning
