Development of a Contextualized Strategic Intervention Materials (CSIMs) on Marine Ecosystem

The aim of this study is to address the gaps highlighted in the results of the performance of Filipino students in PISA and TIMSS namely, misalignment between the curriculum and international standards, lack of teaching resources, and low student engagement specifically in science education. Developing a Contextualized Strategic Intervention Materials (CSIMs) on Marine Ecosystem improves conceptual understanding of science concepts specifically on Ecosystem and assist teachers through the creation of the CSIMS which can be utilized as a supplemental material. This study employs a Quantitative with Qualitative support research design with one group pretest/posttest composed of 46 learners to have a better understanding of the study. The study was anchored on the 4D model developed by S. Thiagarajan, Semmel, and Semmel in 1974, the 4D steps are: (1) Define, (2) Design, (3) Develop, (4) Disseminate. Teaching Ecosystem also aligns with international initiatives like the SDGs, the ones that address life on land (SDG 15) and below water (SDG 14) UN, 2021). The materials are suitable for the learner’s level, based from the panel of evaluator’s ratings with a mean rating of 3.845 interpreted as Very Satisfactory with high marks for Accuracy and up-to-datedness of information, with no significant conceptual, factual, grammatical, or computational errors, confirming the quality and effectiveness of the materials. The Content was rated 3.71, Format with 3.86, and Presentation and Organization with 3.88, all interpreted as Very Satisfactory. The developed CSIMs can be recommended as a basis for developing more Contextualized SIMs for other topics in Biology.
