Design, Development, and Validation of a Strategic Intervention Material in Chemical Reaction

Intervention in education as an additional support resources is important to assist and support struggling learners. This study aimed to design, develop, and validate a Strategic Intervention Material in Chemical Reaction for STEM 11 learners. Chemical reaction, which is a basic subject in Chemistry, is an essential topic that needs to be comprehend by STEM 11 learners. This study used the instructional design of the Analysis, Design, Development, Implementation, and Evaluation (ADDIE). Based on the need analysis identified as one of the top priorities of the proponent’s affiliated school, developing instructional material (IM) that could be used for instruction and better equipped learner learning is highly encouraged. Thus, a SIM-CR resource was designed through Taba’s Grassroot Approach and guided by five cards. This IM was developed and implemented for assessment by potential users and experts. Based on the evaluation phase, the DepEd Learning Resource Evaluation Tool used as a research instrument. The documented responses from all evaluators for the criteria of content, format, presentation and organization and accuracy, and up-to-datedness showed an excellent rating. Qualitative feedback from potential users and experts supported the qualitative and quantitative result through their comments on the IM. Hence, the developed SIM-CR has an excellent face and content validity and is recommended for approval to be used in public schools of the division.
