The Effectiveness of Learning Materials of Inquiry Models to Practice Science Process Skills in Simple Harmonic Motion’s Matter

Abstract

This research aims to know the effectiveness of learning materials of inquiry learning models to practicing science process skills in simple harmonic motion’s matter. This research was conducted on 60 tenth grade students at Muhammadiyah 1 Gresik Senior High School. The effectiveness of this research is seen from science process skills tests, learning achievement, and student response. Science process skills data were obtained from pre-test and post-test. Learning outcomes data were obtained from affective and psychomotor assessment through observation methods and cognitive assessment through the post-test method. While student response data were obtained from the questionnaire method. N-Gain values were obtained from average to high range for each class from the results of pre-test and post-test, this showed the increase in process skills of students. The data analysis of learning achievement indicated that all students have final results that meet the minimum completeness criteria (>75). The data analysis of student responses showed positive results, the highest positive response was the use of student worksheets (LKS) that eases students in learning. Thus, based on the results obtained it can be concluded that this research learning instrument is effective for practice the science process skills in simple harmonic motion’s matter.
