Abstract

Abstract: This study aimed to evaluate the effectiveness of localized video tutorials in improving Grade 9 studentsunderstanding of biodiversity and extinction. Utilizing a quasi-experimental research design, the study compared pretest and posttest assessments to measure the impact of the instructional intervention. A total of 36 participants from Section Agapito Flores were purposively divided into control and experimental groups to facilitate a balanced comparison of outcomes. The instructional approach was based on the 5Es lesson plan framework, which emphasizes active participation and inquiry-based learning. Research instruments included a 20-item multiple-choice questionnaire to assess content knowledge and an adapted 20-item survey to measure retention, comprehension, motivation, and engagement. Data collection involved obtaining school principal approval and participant consent, administering the pretest, implementing the intervention, and conducting a post-intervention survey. Statistical analysis, including means, standard deviations, ANOVA, and Pearson r correlation, revealed that while both instructional methods were effective, the video tutorials significantly enhanced studentsperformance and engagement compared to traditional lecture-based methods. The findings suggest that adopting video tutorials and developing similar instructional materials can lead to improved educational outcomes.
