Abstract

Understanding mathematical concepts is an important key in learning mathematics. However, students often have difficulty understanding mathematical concepts, especially social arithmetic material. Based on this, this research aims to develop information technology-based interactive learning media that can help improve understanding of mathematics concepts for class VII middle school students in social arithmetic material. This research was conducted at SMP Negeri 1 Kalinyamatan involving 34 class VII junior high school students. The research method used is Research and Development (R&D) using the ADDIE Model design. The results of data analysis show that interactive learning media is proven to be valid because it has a significant level of 0.00 < 0.05, feasible because all variables (statements) have a calculated r value > r table and is effective because it meets the individual due diligence and classical due diligence, so it can It is said that the development of interactive learning media based on information technology which was developed is effective in increasing understanding of mathematics concepts for class VII middle school students in social arithmetic material. The evaluation results show that students' understanding of mathematical concepts has increased significantly after using interactive learning media.

Abstract

This study aims to develop a similarity learning module based on ethnomathematics by raising the Troso Jepara fabric motif as a relevant local cultural context, and to examine the validity and practicality of the module in improving students' numeracy literacy. The ethnomathematics approach is used to integrate cultural values ​​in mathematics learning, so that students not only understand the concept of similarity abstractly but are also able to relate it to everyday life. The research method used is the 4D development model (Define, Design, Develop, Disseminate), with a focus on the development and validation stages. For the Disseminate stage, this stage was not carried out. The instruments used include expert validation sheets and teacher and student response questionnaires. The results of the validation by experts obtained an average final score of 3.62, indicating that the module is in the very valid category with several suggestions for product revision, while the results of teacher and student responses obtained an average score of 3.36 indicating that the module is practical to use. Thus, this module can be an alternative contextual and meaningful teaching material in mathematics learning at junior high school level. The results of this study indicate that the developed learning module has met the criteria of being valid and practical for use. Through this study, teachers can integrate local cultural values ​​into mathematics learning, which not only enriches the ethnomathematics approach but also supports the improvement of students' numeracy literacy. This module has a positive impact on students' ability to understand the concept of similarity and apply it relevantly in the context of local culture, so that learning becomes more meaningful and applicable.
