PENGEMBANGAN MODUL AJAR MATEMATIKA PADA MATERI KPK DAN FPB BERBASIS MODEL PBL MENGGUNAKAN MODEL ADDIE UNTUK MENINGKATKAN PEMAHAMAN PESERTA DIDIK

Abstract

The limited supply of teaching modules by The Kurikulum Merdeka, and the content of learning resources that are not enough to encourage active involvement of students are challenges in the learning process. Therefore, this study aims to develop teaching modules based on PBL models that are valid, practical, and effective to improve the understanding of fourth-grade learners. This type of research is research and development using the ADDIE model. Samples were taken using a simple random sampling technique involving fourth-grade elementary school students at SDI Cunca Lawir. Data collection instruments in the form of teaching module product validation sheets, learning implementation observation sheets, teaching module readability instruments, learner knowledge test instruments, and student response questionnaire sheets. The data were analyzed qualitatively and quantitatively through several stages, namely vaidity analysis of teaching modules, practical analysis of teaching modules, and effectiveness analysis of teaching modules. Based on the data analysis, it is known that this teaching module is valid with a percentage of 84% in terms of material, language, and appearance. This teaching module is also practical both from the implementation of learning (79%) with very good category, and the readability of teaching modules (by teachers with a percentage of 97% while by students with a percentage of 90%) with good categories. Teaching modules developed are also effective as seen from the acquisition of N-gain value with an average of 0.46 and the category of “medium”. Thus, developing a mathematics teaching module for the material on Least Common Multiples and Greatest Common Divisor based on PBL is suitable for students to use in the learning process and can improve student learning outcomes.
