Abstract: The invisible flow of electric current in the automotive electrical system circuit becomes a major problem for students to learn how electrical systems work. To overcome these problems, visualisation of flow of electric current in automotive electrical circuit is necessary. In this study, short duration video was developed to visualise the flow of electric current and the video was applied during the learning process of automotive electrical system. The video was developed using DDD-E models and validated by some experts to assure that the video qualifies as a learning medium. The field trial was conducted through quasi-experimental design with single group pre-test-post-test design. This experiment was conducted to test the effectiveness of LdesV during learning process. The results showed that the students' mastery of the starting system increased and varied significantly compared with before using LdesV. Therefore, the use of LdesV in learning was proven effective.

Keywords: LdesV; learning by video; automotive electrical system; starting system; vocational education.
