Validity and practicality of educational videos on the use of oscilloscopes in FI motorcycles

Abstract

This research developed a rigorously validated and highly practical instructional video that illustrated the operation of an Oscilloscope on fuel-injected (FI) motorcycles for incorporation into vehicle testing curricula. The production followed the Multimedia Development Life Cycle (MDLC) framework, advancing systematically through six stages: concept, design, material acquisition, production, trial, and distribution. The final video consisted of eight sequential modules that covered all essential procedures ignition, autoset, sensor measurement, data interpretation. Validation by three subject matter experts yielded a content validity index (CVI) of 0.93 and a media validity index (MVI) of 0.92, both indicating “highly valid.” Practicality assessments involving three lecturers and forty-seventh students produced scores of 91.56 % and 86.07 %, respectively, surpassing the 80 % adequacy threshold. These results confirmed that the video was accurate, well structured, and readily deployable in authentic instructional settings. Moreover, the findings corroborated existing literature that well-designed, interactive video-based media enhanced learner engagement, comprehension, and performance. By addressing a previously unmet need for a dedicated oscilloscope instructional resource in FI motorcycle contexts, this study contributed a novel, evidence-based multimedia tool poised to improve automotive education across both academic and vocational training environments.
