Development of mathematics learning modules with PBL models on the metacognitive skills of students

The teaching materials used do not facilitate students' metacognitive skills, causing students' metacognitive skills to be low. The research aims to produce products in the form of valid, practical, and effective learning modules on the metacognitive skills of grade V students. Teaching materials are developed using the ADDIE development model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. This research developed Mathematics teaching materials with PBL models for grade V elementary school students. The subjects of this study were grade V students of SD Negeri 060874 Medan, which consisted of 27 students. Teaching materials that have been developed meet the validity criteria shown by using validation sheets on aspects of material, language, and design, with each aspect with very valid categories. The teaching materials developed also meet the practical criteria indicated by the questionnaire response given to students after the application of teaching materials with the criteria obtained is very practical. Furthermore, the teaching materials developed also meet the effective criteria, this is shown from the results of the comparison of Pre-test and Post-test tested with N-Gain with the acquisition of N-Gain scores, metacognitive skill questionnaires, and student learning outcomes with moderate categories with effective criteria.
