Abstract
This study utilized a quasi-experimental research design with pretest and posttest assessments to evaluate the effectiveness of enhanced video tutorials on Grade 9 studentsunderstanding of biodiversity and extinction. A total of 36 participants from Section Agapito Flores were purposively selected and stratified into control and experimental groups, facilitating a balanced comparison of outcomes. The instructional approach was grounded in the 5Es lesson plan framework, which emphasized active participation and inquiry-based learning. Research instruments included a 20-item multiple-choice pretest and posttest questionnaire to assess content knowledge, as well as a 20-item adapted survey measuring retention, comprehension, motivation, and engagement. Data collection involved obtaining permission from the school principal and securing consent from participants, followed by the administration of the pretest, implementation of the instructional intervention, and subsequent post-intervention survey. Statistical analysis involved calculating means and standard deviations, alongside employing ANOVA and Pearson r correlation to identify significant differences and relationships between the use of video tutorials and learning outcomes. Results demonstrated that while both instructional methods proved effective, the video tutorials significantly enhanced studentsperformance and engagement compared to traditional lecture-based methods. Consequently, the adoption of the developed video tutorials and the creation of similar instructional materials are highly recommended for improved educational outcomes.
