Abstract

This study aimed to develop a web-based electronic jobsheet system for the periodic motorcycle service subject at SMK Negeri 4 Palembang using the ADDIE model. The development was motivated by the continued use of paper-based practical assessment, which limits documentation and digital integration in vocational learning. The system integrates learning materials, digital jobsheets, procedural checklists, evidence uploads, and assessment features within a platform. The study employed the ADDIE stages of Analysis, Design, Development, Implementation, and Evaluation. Effectiveness testing was conducted during the implementation phase involving 66 Grade XI Motorcycle Engineering students, consisting of 32 students in the experimental class and 34 students in the control class. Data were collected through validation sheets, practicality questionnaires, and pre-test/post-test instruments. The developed system achieved an average validity score of 94.44% and a practicality score of 84.21%, categorized as Very Valid and Very Practical. Learning outcomes in the experimental class improved based on the Paired Sample t-test, with mean scores increasing from 80.28 to 90.16. The N-Gain score was 0.42, categorized as moderate, and slightly higher than the control class score of 0.39. Practical performance was higher, with mean scores of 89.23 and 78.41 respectively. These findings indicate that the developed system is effective.

Abstract

This study was motivated by the limited integration of Android-based mobile devices into learning activities and the low learning achievement of vocational students in Temperature and Heat and Thermodynamics. This study aimed to develop an online Physics module for the Technology and Engineering specialization and examine its validity, practicality, and effectiveness. The study employed a research and development approach using the Instructional Development Institute (IDI) model, consisting of define, develop, and evaluate stages. Product validation involved six experts, comprising three content validators and three design validators. The practicality evaluation involved four Physics teachers and 40 students, while the effectiveness test involved 80 students divided equally into an experimental group (n = 40) and a control group (n = 40). Data were collected using validation and practicality questionnaires and a learning-outcome test. The test instrument was piloted outside the research sample, yielding 27 valid items with a Cronbach’s alpha of 0.92; 20 items were selected for the final test. The results showed valid content (Aiken’s V = 0.730) and design (Aiken’s V = 0.705). The module was rated very practical by teachers (83.33%) and practical by students (68.25%). The experimental group achieved an N-Gain of 0.71 (high), compared with 0.29 (moderate) in the control group. These findings indicate that the developed Android-based online Physics module is valid, practical, and potentially effective for supporting Physics learning in vocational Technology and Engineering education.
