Design and Prototype Testing of the Video Tracker Analysis-Based Uniformly Varied Rectilinear Motion Tool for Uniformly Accelerated Rectilinear Motion and Uniformly Decelerated Rectilinear Motion Experiments

Physics practicum activities have an important role in the learning process because they can provide convenience for students in proving theories. This research aims to develop a prototype uniformly varied rectilinear motion teaching aid based on a video analysis tracker in physics practicum. This study uses research and development with an ADDIE model. The research results show that when an object moves up, the object experiences slowed down, uniformly varied rectilinear motion. Meanwhile, when the object moves down, the object experiences uniformly varied rectilinear motion accelerated. The survey results show that 60% choose the option resulting from the uniformly varied rectilinear motion teaching aids provided adequately, 73.30% agree that the developed tool is easy to operate, and 73.30% experience an increase in understanding after using the tool. Thus, the design and testing of existing prototypes have been successful. The implications of this research can be used to improve students' understanding of concepts through practicum activities. However, this study has limitations, namely, the results of data from Tracker Video Analysis are relatively inaccurate, both in terms of the ability of students to operate it and the inability of the device to operate it. Therefore, developing this research to obtain more accurate data is suggested.
