This study aims to determine: (1) differences in the improvement of mathematical problem solving abilities between students given learning Problem Based Learning (PBL) and guided discovery learning, (2) differences in the increase in student motivation given learning Problem Based Learning (PBL) and guided discovery learning, (3) the process of answering students given learning Problem Based Learning (PBL) and guided discovery learning. This research is a quasi-experimental study. The population of this study was all students of class VII of SMP Negeri 1 Pujud and the sample of this study was students of class VII 2 and VII4, each of which is 30 students. The instruments used consisted of: (1) Tests of mathematical problem solving abilities and (2) Questionnaire of student learning motivation. Data analysis was carried out by analysis of covariance (ANCOVA). The results showed that (1) There were differences in the improvement of mathematical problem solving abilities between students given learning Problem Based Learning (PBL) and students who were given guided discovery learning, (2) There were differences in learning motivation between students who were given learning Problem Based Learning (PBL) with students who were given Guided Discovery learning, and (3) the answer resolution process of students with mathematical problem solving abilities given learning Problem Based Learning (PBL) was better because almost all students could solve the problem by fulfilling the scoring rubric of mathematical problem solving abilities compared to Guided Discovery learning.
