Eksplorasi Pembelajaran IPA Berbasis Socio Scientific Issue Menggunakan Media PhET: Dampaknya terhadap Kemampuan Berpikir Kritis dan Respon Siswa SMP

Abstract

This study aims to determine the effect of Socio Scientific Issue (SSI) based science learning using PhET Simulation media on students' critical thinking skills on energy material. This study uses a quantitative method with a One Group Pretest-Posttest Design. The subjects were 20 students of class VIII B of SMP Labschool UNESA 3. Data collection techniques used critical thinking ability tests, learning implementation observation sheets, and student response questionnaires. Data were analyzed using normality tests, paired sample t-tests, and N-Gain. The results showed that the data were normally distributed so the analysis was continued using paired sample t-tests. The test results showed a significance value of p <0.001 which indicated an increase in students' critical thinking skills after learning. The results of the N-Gain analysis showed that 16% of students were in the high category, 63% in the medium category, and 21% in the low category. The implementation of learning obtained a mode of 4 with a very good category, while student responses obtained a percentage of 88% with a very good category. Based on the research results, it can be concluded that Socio Scientific Issue (SSI)-based science learning using PhET Simulation media can improve students' critical thinking skills in energy topics.
