Abstract

This study aims to determine the effect of problem-based learning models on students' critical thinking skills and problem solving in science concepts at SMP Negeri 7 Palu. The research design was a nonequivalent control group design. Quasi-experimental research method. The population is class VII students. The selected class was Class VII A (n=32) as the experimental class and Class VII B (n=27) as the control class. Data collection used essay test instruments and problem solving essay test questions. Qualitative data, the average teacher observation result is 95.71 with a very active category and the average student observation result is 93.45 with an active category. Quantitative data obtained from the results of data analysis with the t test. The results of the t-test for critical thinking skills are the same as. Asymp.Sig (2-tailed) 0.000 < 0.005) then H1 is accepted. The results of the t test of Asymp.Sig problem solving ability (2-tailed) 0.000 <0.05 H1 are accepted. The results showed that there was a significant effect of the problem-based learning model on students' critical thinking skills and problem solving. concept of science at SMP Negeri 7 Palu.
