ComPADRE Digital Library Abstract:

This paper describes an Easy Java Simulation (EJS) model for students to visualize Newtons 1st and 3rd laws, using frictionless motion and a spring collision during impact. Using Physics by Inquiry instructional (PbI) strategy, the simulation and its problem based inquiry worksheet aim to enhance learning of these two Newtonian concepts. We report results from Experimental (N=62 students) and Control (N=67) Groups in 11 multiple choice questions pre and post tests, conducted by three teachers in the school. Results suggest, at 95 percent confidence level, significant improvement for concept of Newtons 1st Law while not so for Newtons 3rd Law. A Focus Group Discussion revealed students confirming the usefulness of the EJS model in visualizing the 1st Law while not so much for the 3rd Law. We speculate the design ideas for constant velocity motion in the computer model coupled with the PbI worksheet did allow for making sense and experiencing of the 1st Law, where traditional pen-paper representations could not.
