{"abstract":"This study developed a digital interactive supplementary material in Biotechnology for 27 Grade 8 Special Science Class learners at Angono National High School during the 2023-2024 School Year. The material was designed to align with third-quarter Biotechnology competencies, aiming to improve learners' performance. A quasi-experimental design was employed to assess the level of performance before and after exposure to the material. The material's validity was confirmed by master teachers, science instructors, and professors. Pretest and posttest results were analyzed using mean, standard deviation, and dependent t-test. Data showed an improvement in learner performance, moving from “Average” to \"High\" verbal interpretations after exposure to the material. The t-test revealed a significant difference in the level of performance of Grade 8 learners before and after using the digital interactive supplementary material. The study concluded that the supplementary material significantly improved learners' performance across all competencies where it was utilized.","abstract_source":"gemini_shortened","authors":["Bettina Joy Cristo"],"date":"2024-09-20","doi":"10.5281/zenodo.13789992","id":3647,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"85ecb54458495b14f8486121fc2ffe57acdce89c2cbcfab20d0eff886452f46e","schema":"scimatic-article/1","title":"Digital Interactive Supplementary Material in Biotechnology for Grade 8 Learners","volume":25}
