Teachers’ evaluation of MotionAR: An augmented reality-based motion graphing application

Abstract

This research presents the results of the initial evaluation of MotionAR: an augmented reality (AR) based motion graphing application for physics classes. MotionAR uses AR trackers to measure relative motion between objects, hence producing a motion graph. The subject of the evaluation is an improved version of our application that addresses recommendations from the first prototype. Among these recommendations were: the use of words instead of arrows to identify targets, the use of the Cartesian coordinate system, and previews of the displacement vs. time, velocity vs. time and acceleration vs. time graphs. In-service teachers used a 10-item questionnaire for evaluation. The teacher-evaluators come from diverse educational backgrounds (rural and urban schools, 0 to 24 years in teaching, no e-learning model in school vs 1:1 student-to-tablet PC ratio, science vs. non-science majors) which makes the initial evaluation a good baseline data. This ongoing research will present the lessons learned from the evaluation, including insights in developing AR applications for physics classes, and recommendations for teaching motion graphs utilizing AR.
