Abstract:

This research aims to describe the effectiveness of guided inquiry model student worksheet to improve critical thinking skill on heat material in terms of learning outcomes. The research used Control Group Pretest-Posttest Quasi-Experimental Design. The subjects of this research were VII grade of U1 and U2 students of Junior High School 1 with a total of 60 students. The research subjects were determined by using purposive sampling technique. Data collection was conducted by performing test. The results of data analysis with Independent Samples t-Test showed sig. value of 0,022. Because sig. value ≤ 0,05,H_0was rejected orH_1was accepted. Product effectiveness level based on the mean of normalized gain from pretest and posttest value of experimental and control groups demonstrated that N-gain of experimental group was 0,48 and N-gain of control group was 0,38. Therefore, it can be stated that the improvement of students’ critical thinking skill of experimental group or group which used development product student worksheet was higher than the improvement of students’ critical thinking skill of control group which used conventional student worksheet. It can be concluded that the learning which uses guided inquiry model student worksheet is more effective in improving critical thinking skill than the learning which uses conventional student worksheet.
