Development of Mathematics Module Based on M-APOS Learning Model to Improve Students’ Mathematical Problem Solving Ability

Abstract This research aimed to develop mathematics module based on M-APOS learning model to improving students mathematical problem-solving abilities grade VII. This research used the Research and Development (RnD) method. The development model used is Analysis, Design, Development, Implementation, Evaluation (ADDIE). Data collection techniques include observation techniques, questionnaires, and math problem-solving skills tests. The result of the research that the development of a mathematical module is based on the M-APOS learning model to improve mathematical problem-solving abilities in the quadrilateral material of class VII of Junior High School by fulfilling valid, practical and effective criteria.
