Pengembangan Bahan Ajar Berbasis PMRI Materi Perbandingan Senilai dan Berbalik Nilai Melalui Liveworksheets untuk Meningkatkan Kemampuan Literasi Numerasi dan SRL

Abstract

The cognitive and affective abilities needed in this modern era are numeracy literacy and self-regulated learning (SRL). Based on the results of preliminary research conducted at a public junior high school in the Cijantung area on the material of comparison of value and reciprocal value, the three indicators of numeracy literacy were still below 50% and the average percentage of SRL success only reached 45.75%. Students' numeracy literacy and SRL abilities are influenced by the learning resources, media, and learning approaches used. Therefore, it is necessary to develop PMRI-based teaching materials through liveworksheets. The purpose of this study is to produce a product in the form of teaching materials using PMRI-based liveworksheets on the material of comparison of value and reciprocal value. This study was conducted in the even semester of the 2024/2025 academic year. The sample used consisted of 36 seventh grade students. The type of research used was R&D with the ADDIE model. Data analysis used the pre-test post-test control group method which was used to test the effectiveness of the product. The results of the study showed that the developed product was categorized as very valid (93,79%) based on expert assessments consisting of material aspects (89,93%), media (96,44%), and language (95,00%). The developed product was very practical (88,985) based on teacher responses (89,58%) and students (88,68%). Through n-gain calculations, this teaching material was effective in improving numeracy literacy skills to the high category (0,8) but could only improve SRL to the moderate level (0,46).
