Conceptual Understanding Through Differentiated Interest-Based Learning and Instruction (DIBLI) in Teaching Exogenic Processes in Earth and Life Science

This research affirmed that Differentiated Instruction (DI) using the Interest-based Learning (IBL) or Differentiated Interest-Based Learning and Instruction (DIBLI) strategy at Canduman National High School at H. Abellana St., Canduman, Mandaue City, Cebu, showed efficacy in dealing with mixed-ability learners having diverse learning styles and interests during the first quarter of S.Y. 2024-2025, as the basis for the Enhanced Detailed Lesson Plan in teaching exogenic processes in Earth and Life Science. A mixed-methods design was applied in the study with 47 respondents. The pre-test and post-test scores were gathered using the adapted questionnaires. The respondents were also asked about the challenges they encountered. Based on the findings, the learners’ performance on the pre-test and post-test reveals a significant increase in scores for competencies of describing how rocks undergo weathering and explaining how the products of weathering are carried away by erosion and deposited elsewhere, while a non-significant improvement was observed for making a report on how rocks and soil move downslope due to the direct action of gravity. The non-significant outcome regarding the competency of making a report on how rocks and soil move downslope due to the direct action of gravity does not necessarily indicate that the learning material is ineffective; rather, it highlights areas needing improvement. Moreover, the respondents’ feedback to challenges they encounter about the implementation of the Differentiated Interest-Based Learning and Instruction (DIBLI) strategy reveals four main themes:(A) Struggles in Managing Time, (B) Limitations in Resources and Accessibility Issues, (C) Difficulties in Sustaining Engagement and Aligning Interests, and (D) Issues with Visual Learning and Interpretation. There is a need for additional time to plan and implement differentiated instruction effectively. In addition, develop an upgraded, detailed lesson plan to guarantee the effective use of the lesson in order to enhance learners’ scores in the lesson.
