Effect of Discovery Learning Implementation Model on Buffer Solution Material on Critical Thinking Ability and Metacognition Awareness of Senior High School Students

Abstract

This study aims to determine the effect of applying the discovery learning model on critical thinking skills and metacognitive awareness of class XI IPA students at SMA Negeri 3 Palu. The research method used is a quasi-experimental design with a pretest-posttest control group design. The results of the statistical test for critical thinking skills obtained sig = 0.001 and metacognitive awareness sig = 0.031 with the criteria of accepting H0 if Sig. > 0.05 and reject H0 if Sig. <0.05. sig. value < 0.05, then H0 is rejected. While the correlation test obtained sig. = 0.966 so that H0 is accepted. The results showed that: (1) the application of the discovery learning model had a positive effect on students' critical thinking skills in the buffer solution material, (2) the application of the discovery learning model had a positive effect on students' metacognitive awareness in the buffer solution material, (3) there was no relationship between the ability critical thinking and metacognitive awareness of students on buffer solution material.
