The improvement of critical thinking skills through problem based learning models assisted by trackers video on parabolic movements

Abstract

This study aims to improve critical thinking skills using a problem-based learning model assisted by video tracker on parabolic movements. This research was conducted in class X Senior High School Pandeglang. This study uses one group pretest-posttest design with paired sample t-test analysis technique. Learning is done by conducting demonstration activities of parabolic movement based on problem based learning. The results of the video footage of the parabolic motion demonstration were then analyzed using a video tracker application. Based on the results of the study obtained the average score of critical thinking skills increased by 53.936% with a moderate N-Gain average (0.536) at a confidence level of 95%. These results show that learning using a tracker can improve critical thinking skills well. Based on the test results obtained signification of 0.00, it can be concluded that there are significant differences in critical thinking skills before and after learning using the tracker.
