Abstract

This research focuses on the utilization of teaching materials in mathematics concerning fractions that are less engaging and fail to connect mathematical concepts with concrete and beneficial situations in students' lives. The aim of this study is to create a teaching product on Fractional Material using the PMRI approach and linking it with the Musi Rawas Tourism Context, which is not only scientifically valid but also easily applicable in practice. The research was conducted in Grade V at Elementary School 58 Lubuklinggau. This study is a developmental research that utilizes a development model adapted from the Four-D model. This model consists of four stages, namely: 1) the definition stage, 2) the design stage, 3) the development stage, and 4) the dissemination stage. Data were collected through interviews and questionnaires. Evaluation by experts yielded validation scores of 0.82 for language experts, 0.84 for media experts, and 0.73 for subject matter experts, with an average score of 0.80. Meanwhile, the analysis of teacher practicality showed an average score of 0.90, and for student practicality, the average score was 0.87. Therefore, it can be concluded that the Teaching Material on Fractions Based on PMRI and Utilizing the Musi Rawas Tourism Context has met the standards of validity and practicality, making it suitable for implementation in the learning process regarding fractions.

Abstract

This research aims to develop a teaching material design based on PMRI (Indonesian Realistic Mathematics Education). It involves testing the validity, practicality, and effectiveness of PMRI-based teaching materials on statistical subjects at SD Negeri 2 Bangun Jaya. This type of research is Research and Development (R&D) with a 4-D development model. The subjects of this study are the fifth-grade students of SD Negeri 2 Bangun Jaya. Data collection techniques include interviews, observations, questionnaires, and tests. Based on validation results from experts, the PMRI-based teaching materials meet the validity criteria with average scores of 0.82 from language experts, 0.93 from content experts, and 0.88 from media experts. The analysis of the practicality assessment sheets from teachers' responses and small group responses indicates that PMRI-based teaching materials meet the practicality criteria, with small group scores averaging 98% (very practical) and teachers' responses averaging 96,87% (very practical). The effectiveness test resulted in an N-gain (g) of 0.77 with a high classification, indicating that the PMRI-based teaching materials have high effectiveness. Based on the research results, it can be concluded that the PMRI-based teaching materials for statistical subjects using the Musi Rawas tourism context are proven to be valid, practical, and effective, making them suitable for use.
