  1. PAPER • OPEN ACCESS Using Tracker to understand 'toss up' and free fall motion: a case study  and Published 19 June 2015 • © 2015 IOP Publishing Ltd   


    This paper reports the use of Tracker as a computer-based learning tool to support effective learning and teaching of 'toss up' and free fall motion for beginning secondary three (15 year-old) students. The case study involved (N = 123) students from express pure physics classes at a mainstream school in Singapore. We used eight multiple-choice questions pre- and post-test to gauge the impact on learning. The experimental group showed learning gains of d = 0.79  ±  0.23 (large effect) for Cohen's d effect size analysis, and gains with a gradient of <g> total = 0.42  ±  0.08 (medium gain) above the traditional baseline value of <g> non interactive = 0.23 for Hake's normalized gain regression analysis. This applied to all of the teachers and students who participated in this study. Our initial research findings suggest that allowing learners to relate abstract physics concepts to real life through coupling traditional video analysis with video modelling might be an innovative and effective method for teaching and learning about free fall motion.
