Development of Multimedia Based on Advanced Powerpoint and a Problem-Based Learning Model for Reading Workmanship Signs

Abstract

This research aims to develop Advanced PowerPoint-based multimedia using the Problem-Based Learning (PBL) model and the ADDIE method. The material used in this research is workmanship signs. The objectives of this study are to: (1) test the feasibility of the developed multimedia based on Advanced PowerPoint and the Problem-Based Learning model, (2) evaluate the differences in learning outcomes between public and private vocational schools, and (3) Analyze the extent of improvement in learning outcomes among students who receive instruction using Advanced PowerPoint-based multimedia with the PBL model, compared to those who receive conventional instruction. Data were analyzed using one-way ANOVA, and the results showed a statistically significant difference between the tested groups. Furthermore, the LSD post hoc test revealed significant differences between pairs of groups, indicating that classes using Advanced PowerPoint-based multimedia with the PBL model achieved the highest learning outcomes. In contrast, private vocational school classes showed moderate N-Gain values. In conclusion, Advanced PowerPoint-based multimedia combined with the PBL model is effective in improving student learning outcomes in the topic of workmanship signs.
