Development of a 2-D Motion Tracker Application Project Assisted By Computer Vision to Enhance Student’s Laboratory Skills

Abstract

The lecture method that is often applied by the teacher in class can also cause the learning experience of students to not be optimal; as a result, students only understand the theory and concept of projectile motion. One method that can be used to learn physics is the experimental method. This study aims to produce a projectile motion tracker application project and describe the effect of applying this application project in the physics learning process, especially related to students' laboratory skills. The research method used is research and development (RD), using the 4-D development model (Define, Design, Develop, and Disseminate). Pre- and post-test results were obtained from 74 high school students to assess their laboratory skills before and after treatment. The instruments used were questionnaires and tests. The results show that the projectile motion tracker application project can be employed as a tool for physics education, based on expert test results with very good categories in language, visual appearance, and software engineering. In addition, based on the results of the practicality test for teachers and students, the test results were in the very practical category, respectively, from the aspects of ease of use, attractiveness, efficiency, and usefulness. The results of students' pre- and post-test on their laboratory skills show that the projectile motion tracker application project can enhance students' laboratory skills. The projectile motion tracker application project can be used as an alternative by teachers, lecturers, or education practitioners to support teaching and learning activities.
