Reportorial Activities with PowerPoint Presentation: their Impacts to Retention Level of the Learners

Abstract

This study investigated the impact of incorporating PowerPoint presentations into reportorial activities on student knowledge retention. Using both pretests and posttests, the researchers carefully compared a control group with an experimental group. Results showed significantly improved posttest scores in the experimental group, clearly indicating enhanced knowledge retention through the use of PowerPoint presentations as an educational tool. While students in both groups demonstrated measurable improvement, the experimental group exhibited a noticeably higher proportion of very good scores compared to the control group. This study also utilized a survey questionnaire on student perceptions, focusing on aspects such as clarity, visual appeal, and ease of use. Responses were strongly positive across these areas, although the relationship between these perceptions and posttest scores varied between the two groups. Notably, only visual appeal showed a statistically significant relationship with posttest scores in the experimental group, suggesting that students may retain information better when presentations are visually engaging. The findings suggest that well-designed PowerPoint presentations can be a valuable and effective tool for enhancing learning outcomes, particularly when they are aligned with sound pedagogical principles. Further research is strongly recommended to explore the impact of interactive features and to examine the long-term retention effects of such multimedia instructional methods.
