Abstract

Creativity ini mathematics learning is one of goal recommended by Ministry of Education Indonesia. Creativity in mathematics useful for solving mathematics problems which can enhance with project-based learning (PjBL) and problem-based learning (PBL). The purpose of this study is to determine the effect of project-based learning (PjBL) and problem-based learning (PBL) on students' creative thinking ability. The method used was quasi-experimental with a pretest-posttest-only control design. The populations of this study were the senior high school students from senior high school Menggala 1. The sample obtained through the random sampling technique which three classes as the sample of this study. Data were collected using essay test to measure student's creativity. Hypotheses were tested using one-way ANOVA test techniques with unequal cells. Based on the results of the study, it is obtained that the comparative data, so it can be concluded that there are differences in the students' average creative thinking ability based on the PjBL model, PBL model, and direct learning model. This research recommend that teachers must develop their learning strategy instead only using directed learning in teaching mathematics.
