Abstract

This research is significant in answering the challenges of increasingly sophisticated technology in creating worksheets using Geogebra software. This research aims to produce digital worksheet products using GeoGebra online based on students' geometric thinking levels that are valid and practical to use in teaching and learning processes in the classroom, both online and offline. The research method used in this study is research and development (Research and Development) with the ADDIE model. The ADDIE model has five stages: analysis, design, development, implementation, and eval__uation). The subjects of this research were students of the mathematics education study program for the 2021/2022 academic year. The instruments used were material and media expert validation sheets and student response sheets. The results of this study are digital worksheet products using GeoGebra Online based on students' geometric thinking levels that are valid and practical to use. Digital worksheets using GeoGebra online is an innovative use of technology that integrates student activity sheets.

Abstract

This study aimed to develop a reasoning-oriented history of mathematics e-module for second-semester students of the Tadris Mathematics Study Program at Universitas Islam Sarolangun and to determine its validity, practicality, and effectiveness. This study employed a Research and Development (R&D) method using the ADDIE development model, which consists of analysis, design, development, implementation, and evaluation stages. The research subjects consisted of expert validators and second-semester students of the Tadris Mathematics Study Program at Universitas Islam Sarolangun. Data were collected through observations, interviews, questionnaires, mathematical reasoning tests, and documentation. The data were analyzed descriptively using quantitative and qualitative approaches with a Likert scale. The results showed that the developed e-module obtained an average validity score of 88.25% categorized as very valid and an average practicality score of 91% categorized as very practical. The effectiveness test indicated that the e-module was effective in learning activities with a classical completeness percentage of 82.35%. The reasoning-oriented history of mathematics e-module developed in this study is feasible to be used as an innovative digital teaching material to facilitate students’ mathematical reasoning abilities in History of Mathematics learning.
