Development of Contextualized Learning Activity Packets in Biodiversity for Grade 10 Learners

The study aimed to develop Contextualized Learning Activity Packets (CLAPs) in teaching biodiversity. Biodiversity is a difficult subject in high school as it requires a deep understanding of ecological concepts and complex issues (Suryanda et al., 2020). There are no existing studies that used the mangrove ecosystem as a main input to teach biodiversity. The developed CLAPs would help students gain a conceptual understanding of biodiversity within the context of the mangrove ecosystem. It would also help them understand the topic better since the lesson is localized. This clap contains various activities that involve reading, solving, species identification, poster making for invasive species, drawing, teamwork, and decision-making. The two (2) least mastered competencies from the study of Santos et al. (2021) in the K-12 science curriculum guide, specifically biodiversity, served as a foundation of this lesson. Based on the results of the needs assessment, it was evident that there is a need to develop CLAPs for the participating school. The CLAPs were rated as very satisfactory with an average mean of 3.87 in terms of content, format, presentation, accuracy, and up-to-dateness information. Therefore, based on the findings and analysis, it is considered valid and acceptable supplementary material for classroom use.
