This study aims to 1) analyze the effect of the problem based learning model in terms of motivation to learn physics, 2) analyze the effect of the problem based learning model in terms of students' science process skills, 3) analyze the effect of the problem based learning model on students' learning motivation and science process skills in terms of from the grade level, and 4) analyzing the effect of the problem based learning model on students' learning motivation and science process skills in terms of learning materials. The type of research applied in this study is a meta-analysis. The results of this study are: 1) the problem based learning model has an influence on the motivation to learn physics for high school students with an average effect size of 0.73 in the medium category, 2) the problem based learning model has an effect on students' science process skills with an effect size 0.62 medium category, 3) problem based learning learning model has an influence on learning motivation and physics science process skills at the level of class X, XI and XII with an effect size of 0.86 high category, 0.47 medium category and 0.28 category medium, and 4) the problem based learning model has an influence on learning motivation and science process skills on dynamic electrical material with an effect size of 2.02 in the high category.
