Development of ethnomathematics-based curved three-dimensional shape learning media using augmented reality

Abstract

Geometry is very important to study in Mathematics, one of which is in the material of curved three-dimensional forms. However, many students still have difficulty learning the material, which affects their creative thinking ability, which is still not optimal. Therefore, we need innovative media development using the right context, one of which is using Augmented Reality-based Ethnomathematics. This study aims to develop ethnomathematical-based media using Augmented Reality, which is oriented toward the ability to think creatively. This research is a type of development research with the ADDIE model. This article will discuss the results of the analysis, design, and development stages. The subjects in this study were ninth-grade students in one of the junior high schools in Semarang. Data collection in this study used the questionnaire method by analyzing Augmented Reality learning media based on Ethnomathematics. The validation data from experts were analyzed using the mean formula to determine the average media validity score. The analysis results showed that the average score of Ethnomathematics-based media validation using Augmented Reality oriented toward creative thinking skills was 87% with excellent qualifications and material validation with 90% with excellent qualifications. Thus, ethnomathematics-based media using Augmented Reality, which is oriented towards creative thinking skills, can be declared valid and have excellent qualifications. This media development can then be implemented in the classroom to find out the potential effect on students' creative thinking ability and is expected to inspire educators to develop media by involving cultural exploration.
