The Development of Digital Teaching Materials Based on Microlearning Integrated with Flipbook to Help Students Improve Mathematical Communication Skills on the Topic of Linear Equations in Class VIII at SMP Negeri 17 Medan.

Abstract

This study aims to: (1) obtain Microlearning-based digital teaching materials that are valid, practical and effective so as to improve students’ mathematical communication abilities; (2) describe the improvement of students’ mathematical communication skills through Microlearning-based digital teaching materials.

The subjects in this study were class VIII-5 students of SMP Negeri 17 Medan for the academic year 2022/2023, while the objects in this study were Microlearning-based digital teaching materials on Straight Line Equations. This research is a Research & Development (R&D) research using a 4D development model namely Define, Design, Develop and Disseminate. The results of this study indicate that: (1a) Microlearning-based digital teaching materials based on the validator’s  are in the valid category with an average score for material is 3.64 and an average score for media is 3.46; (1b) Microlearning-based digital teaching materials are included in the very practical category with a teacher response score of 90.63% and an overall student response of 80.09%; (1c) Microlearning-based digital teaching materials have met the effective criteria in terms of classical learning completeness with a percentage of 85.71%, the achievement of indicators/learning objectives for each indicator has been achieved; and (2) the students’ mathematical communication  abilities increased, judging by the mathematical communication abilities of each indicator that had increased and the N-Gain value increase from the pretest and posttest obtained was 0.47 in the medium category.
