Development of Strategic Intervention Material (SIM) to Improve the Least Mastered Skill in Central Dogma among the Grade 10 Learners
Main Article Content
Abstract
The study focused on the development of a Strategic Intervention Material (SIM) and its effectiveness in improving students' performance in the topic of Central Dogma of Molecular Biology. The study was conducted at Cabalantian National High School, to selected thirty-two (32) Grade 10 learners. Topics include DNA Replication, Transcription and Translation which was identified as the least mastered learning competency based on the test results. The study used quasi- experimental research method. The developed SIM was evaluated by master teacher and science teachers in terms of Sub tasking, Congruence, Usability and Replicability. The results of the study showed a significant difference between the pre-test and post-test scores, indicating that the SIM positively impacted student outcomes. The activities provided in the SIM played a substantial role in this improvement. Students had a positive view of the SIM, finding it enjoyable and interesting, and it contributed to a positive attitude towards learning science concepts. Overall, the study suggests that using intervention materials is recommended as an effective strategy for improving students' performance in science education.
