PENGARUH MODEL GUIDED INQUIRY BERBANTUAN MULTIMEDIA INTERAKTIF TERHADAP KETERAMPILAN BERPIKIR KRITIS SISWA SEKOLAH DASAR

Abstract

This research is motivated by the low critical thinking skills of elementary school students in science learning, particularly on economic activity material. This is caused by the learning process which is still dominated by lecture methods and the minimal use of interactive learning media. This study aims to examine the effect of the Guided Inquiry model assisted by interactive multimedia on students' critical thinking skills. The research method used is quasi-experimental with a Nonequivalent Control Group Design. The research sample involved 56 fifth-grade students of SDN Cisarua, Sukabumi City, divided into experimental class (28 students) and control class (28 students). Data were collected through critical thinking skills test instruments in the form of pretest and posttest. Data analysis techniques include normality tests, homogeneity tests, Independent Sample t-Test, and N-Gain tests. The results showed an increase in the average score in the experimental class from 40.93 (pretest) to 87.86 (posttest), while the control class increased from 40.96 to 62.14. Based on the hypothesis test, a significance value (Sig. 2-tailed) of 0.000 < 0.05 was obtained, meaning H0 is rejected and H1 is accepted. Furthermore, the N-Gain test results showed the experimental class achieved 0.798 (79.76%) in the high category, while the control class only achieved 0.353 (35.32%) in the medium category. In conclusion, the application of the Guided Inquiry model assisted by interactive multimedia has proven to have a significant and effective effect in improving the critical thinking skills of elementary school students.
