Guided inquiry-based on practicum to improve critical thinking skills on the subject of Newton's law

Abstract

This study aims to determine the effectiveness of guided inquiry-based on practicum to improve critical thinking skills on Newton's law concept. The method used in this study is a quasi-experimental method through a non-equivalent control group design. This research was conducted by applying guided inquiry-based on practicum in the experimental class and conventional practicum in the control class. The type of approach used is a quantitative approach. The population in this study were all students of grade ten Senior High School 1 Bireuen, in which two classes of each class consisting of 30 students were used as research samples selected using a purposive sampling technique. Data collection was obtained using a test instrument of critical thinking skills in the form of description questions given at the initial and final tests. The results of data analysis with the t-test show the use of guided inquiry-based on practicum on Newton's law concepts can significantly improve students' critical thinking skills compared to the use of verification-based practicum. This can be seen from N-gain critical thinking skills for the experimental class which is equal to 0.71, higher than the control class with N-gain of 0.53.
