Improvement in learning coordinate systems topic for Electrical Engineering students using Interactive Multimedia

Coordinate system is a basic topic in engineering students in our department. Some advance subjects use this topic as the basic knowledge for analysis both electrical and information technology study programs, such as electromagnetism and computer vision. Main function of them is to represent such a position of a matter in space. In delivering this topic, some problems came up when it was presented by conventional method of teaching, such as by explaining it on a whiteboard or using presentation slides. Text font was limited related to the size of classroom. Steps of drawing the coordinate systems were not clear when it was only explained in one slide without any animations. By developing this topic in interactive multimedia, the teaching method can be improved using one of existing e-learning system in our university, called eLisa, which is not limited by time, distance, and also can overcome those mentioned problems due to this simple and clear visualization of Cartesian, Cylindrical, and Spherical Coordinate Systems. This research is conducted to investigate the benefit of the developed multimedia to improve knowledge of students about the topic. This investigation used t-test to find the significance improvement of learning the topics using this interactive multimedia by doing a hands on quiz and walkthru method to find the multimedia in eLisa. The result showed that by learning it in 15 minutes, the knowledge of students was improved based on data scores of quiz as a measurement instruments.
