Developing instructional materials on mathematics logical thinking through the Indonesian realistic mathematics education approach

Abstract

Instructional materials are one of the essential parts to support the learning process becomes more exciting and meaningful. However, teachers do not yet give more attention to these parts, so that the learning process becomes uninteresting and boring. Therefore, this research aims to produce the instructional materials for the logical thinking of mathematics ability based on Indonesian Realistic Mathematics Education for junior high school students for Grade 8, which is valid and practical. This research used a design research method with the type of development study conducted in two stages, namely preliminary design and formative evaluation, including self-evaluation, prototyping (expert reviews, one-to-one, and small groups) field tests the research conducted at junior high school. For research subjects, students of class VIII B of junior high school are 29 students. The techniques of data collection used are documentation, walkthrough, interviews, and test. The research data are quantitatively and qualitatively analyzed. The results of data analysis known that this research produces the logical thinking of mathematics for instructional materials based on Indonesian Realistic Mathematics Education on the content of linear equations of two variables that are valid, practical, and have potential effects. In this case, mathematics instructional materials in students' worksheets based on Indonesian Realistic Mathematics Education have been content valid, constructive, and language from expert validation at the expert review stage. In contrast, the mathematics student worksheets based on Indonesian Realistic Mathematics Education have been practically obtained from revisions results of one-to-one and small group. Furthermore, the prototype of instructional materials in the form of student worksheets has potential effects to improve the logical thinking of mathematics ability for students.

Upaya Meningkatkan Belajar Matematika Melalui E-LKPD Interaktif Muatan Matematika Materi Simetri Lipat dan Simetri Putar

“…E-LKPD Interaktif Muatan Matematika dikembangkan dengan inovasi dan valuasi menarik sehingga dapat merangsang peran aktif peserta didik dalam pembelajaran. Pengemasan E-LKPD yang inovatif dapat membantu belajar mandiri (Agitsna et al, 2019;Purwitaningrum & Prahmana, 2021). E-LKPD Interaktif merupakan sebuah media pembelajaran yang telah dirancang yang akan memuat materi pembelajaran, video penjelasan materi dan beberapa soal-soal interaktif.…”

Lembar Kerja Elektronik Berbasis Project Based Learning Pada Muatan Pelajaran IPA

“…LKPD yang disajikan dalam bentuk digital akan mempermudah proses belajar siswa, kususnya dalam proses pembelajaran daring di masa pandemi. E-LKPD berisikan rangkaian kegiatan yang dapat digunakan untuk penyelidikan dan penyelesaian sebuah masalah (Purwitaningrum & Prahmana, 2021;Yustina & Kapsin, 2017). Penggunaan akan memberikan dampak aktifitas belajar yang menyenangkan bagi siswa.…”

Developing interactive e-module based on realistic mathematics education approach and mathematical literacy ability

“…In addition, mathematics learning will be more meaningful and justified using the RME approach (Heriyadi & Prahmana, 2020). This is because RME always presents and connects all mathematical problems in a real context so that students' learning processes are related to their experiences in everyday life (Hough et al, 2019;Purwitaningrum & Prahmana, 2021). Previous studies show that RME has a positive impact on improving students' mathematical literacy skills (Hilaliyah et al, 2019;Heriyadi & Prahmana, 2020;Putri et al, 2020).…”
