Abstract

Abstract: Background: This study aimed to develop an Interactive Teaching Module based on Differentiated Instruction in geometry material to accommodate the diversity of mathematical problem-solving abilities of seventh-grade students at MTs Mujahidin Pontianak. The study employed a Research and Development (R&D) method using the 4D development model modified into 3D, consisting of the define, design, and develop stages. The research subjects consisted of four expert validators, namely two Mathematics Education lecturers, one Information Technology Education lecturer, one mathematics teacher, and 30 seventh-grade students as the trial subjects. Data were collected through validation sheets, teacher and student response questionnaires, and tests of mathematical problem-solving abilities. The results showed that the module met the criteria of being highly valid with an average validation score of 94.7%, highly practical based on teacher responses of 93.33% and student responses of 85.58%, and effective with an average posttest score of 71.67 and a learning mastery percentage of 66.67%. The module also improved students’ activeness, enthusiasm, and ability to solve problems using Polya’s problem-solving stages according to their respective abilities. Therefore, the module is feasible to be used in mathematics learning to support the diversity of students’ abilities.

Abstract

Mathematics learning in schools still faces obstacles in the form of diversity in students' mathematical problem-solving abilities that have not been optimally accommodated in the learning process. This study aims to develop an Interactive Teaching Module based on Differentiated Instruction for geometry material for seventh-grade students at MTs Mujahidin Pontianak and to determine its level of validity, practicality, and effectiveness. The study used the Research and Development method with a 4D development model modified into 3D, including the define, design, and develop stages. The research subjects consisted of four expert validators and 30 seventh-grade students as trial subjects. Data were collected through validation sheets, teacher and student response questionnaires, and mathematical problem-solving ability tests. The results showed that the module obtained a very valid category with an average of 94.7%; very practical, based on teacher responses of 93.33% and students of 85.58%; and effective, with an average posttest of 71.67 and learning completeness of 66.67%. The research findings show that the Interactive Teaching Module based on Differentiated Instruction is suitable for supporting adaptive, interactive mathematics learning and is oriented towards developing students' mathematical problem-solving abilities in line with diverse learning abilities.
