Abstract:

The students’ engagement and learning vary depending on the materials used in the respective classes. This study designed, developed, and validated a science 8 learning packet in biodiversity for Grade 8 students at one of the public schools in the Schools Division of Talisay City, Cebu, during the school year 2024-2025, as the basis for the proposed learning packet enhancement. This study employed a quantitative research design engaged in descriptive-evaluative research in determining the students’ conceptual understanding and the extent of experts’ satisfaction. Anchored in the Analyze, Design, Develop, Implement, and Evaluate (ADDIE) Model. A rating sheet for learning materials from the Department of Education and a conceptual inventory test in science 8 were adopted. The study’s empirical findings revealed a significant difference in students’ initial and final conceptual understanding of biodiversity concepts. The extent of satisfaction of the experts upon validating the learning packets revealed the extent of very satisfied, with some comments and suggestions. Based on the findings, the researchers concluded that the students’ initial and final conceptual understanding of biodiversity concepts before and after utilizing the learning packets significantly differed. Thus, the use of the Learning Packet in Science 8-Biodiversity in the following school years is recommended to provide students with a variety of learning engagements and to develop their conceptual understanding in Science 8.
