Abstract

Learning mathematics at the junior high school level is often considered difficult and uninteresting because the material rarely relates to everyday life. This study explores the concept of ethnomathematics in traditional apem cakes as a source of contextualised teaching materials in mathematics. A descriptive, qualitative method was employed, utilizing observation, documentation, and interviews with two informants who were knowledgeable about the history and preparation of apem cakes to collect data. The results showed that apem cakes have geometric shapes, such as circles and cones, which can be used to teach geometric concepts, including area, circumference, and volume, as well as calculations and ingredient comparisons. Additionally, the cultural significance of apem cakes can enrich the learning experience and boost student engagement. The study concludes that apem cakes have the potential to serve as a meaningful and contextual learning medium. Practically, teachers can design lesson plans utilising apem cake-based calculation examples to make learning more active and relevant for students. However, this study is limited to two informants and has not yet been tested in the classroom, so the results remain descriptive. Further research is recommended to develop student worksheets based on apem cakes and test their effectiveness with junior high school students.

Abstract

The aim of this study is to produce realistic mathematics education (RME)-based learner worksheets (LKPD) on exponent material to improve critical thinking skills of grade X students that are valid, practical and effective. The method used is Research and Development (R&D) with the ADDIE model, which includes the stages of analysis, design, development, implementation and evaluation. The results showed that the realistic based LKPD on exponent material was very valid based on the results of expert validation with a score of 87.5%, the practicality of realistic-based LKPD learning media was considered practical based on teacher and student responses with a score of 79.7%. In addition, its effectiveness can be seen from the increase in student learning outcomes with an average post-test score of 85.38%. The statistical test results show a significance value of 0.001 (two-tailed), indicating a significant difference between the pre-test and post-test results. Therefore, it can be concluded that the development of realistic-based worksheets improves students' critical thinking skills. The Realistic Mathematics Education approach links mathematical concepts to real-life situations, motivating students and helping them to understand exponential material more deeply. This study makes a valuable contribution to mathematics education by improving students' analytical and reasoning skills and facilitating a more meaningful, contextualised learning of exponents.
