Abstract

The selection of Student Activity Sheets (LKPD) is carried out to direct students' independent learning to help them understand the learning material. With local wisdom RME-based LKPD, students have a relatively firm understanding of mathematical problems. The purpose of this study is to develop LKPD products based on Realistic Mathematical Education (RME) with local wisdom of DAM Raman and Capit Urang Metro tourism objects on KPK and FPB materials that are suitable for use and are effective in mathematical problem-solving abilities. This type of research is research and development research and development (RnD) Borg and Gall. The population of this study was fourth-grade elementary/MI students in the Madrasah Working Group (KKM) 2 Metro City. The sampling technique used the class IV purposive sample technique at MINU Metro. The results of this study indicate that the development of RME-based LKPD products with local wisdom is declared feasible based on the results of validation from experts and is practical to use in terms of attractiveness, convenience, and usefulness. RME-based worksheets are effectively used in students' mathematical problem-solving abilities.

Abstract

The development of this product aims to facilitate teachers and students in learning statistics to be more efficient so as to achieve completeness in terms of understanding students' mathematical concepts. The product developed was validated by experts and the results showed that the product was in the valid and feasible category to be applied in learning. Furthermore, limited trials were carried out on several students and teachers to see the practicality of the product, getting the results that the product developed was classified as very practical. The research was continued by testing this product in learning. The sample for this product trial was selected by purposive sampling. This research design uses a pretest-posttest control group design with 2 classes consisting of an experimental class using excel-based media and a control class using conventional learning. Hypothesis testing using the t-test showed that at the time of the pretest there was no difference in average between the two classes, while at the posttest there was an average difference between the two classes. Followed by the N-Gain test to see the average increase between the pretest and posttest results from the two classes showing the results that the average increase in understanding mathematical concepts in the experimental class is higher than the average increase in understanding mathematical concepts in the control class. So it can be concluded that the product developed is valid, practical, and effective in increasing students' understanding of mathematical concepts.
