Developing An Assure-Based Mathematics Teaching Module To Enhance Learning Effectiveness

This study aims to develop a Merdeka Curriculum-based teaching module employing the ASSURE model in the subject of mathematics, specifically on the topic of function composition applications, to enhance learning effectiveness as assessed by its validity, practicality, and effectiveness. The study employed the ADDIE development model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The instruments used include validation sheets, teacher observation sheets, student response questionnaires, and pretest-posttest assessments.Based on the validation data analysis, the teaching module received a validity score of 3.83, categorized as highly valid. The practicality analysis, based on teacher observations, yielded a score of 92.8%, which falls under the “very good” category, while the student response questionnaire obtained a score of 89.9%, indicating that the module was applicable without revision. The effectiveness analysis, based on the comparison between pretest and posttest scores, showed an N-Gain value of 0.7442, categorized as high. Therefore, the developed teaching module meets the criteria of being valid, practical, and effective for use in the learning process.
