Abstract

The research on the development of independent curriculum modules based on geoboards and geogebra applications aims to overcome the difficulties faced by students in learning geometry, precisely in recognizing the shape of flat buildings in grade 1. This study uses a development research method with a 4D development model (Define, Design, Develop, and Disseminate). The development process of this teaching module is carried out in 4 stages starting from the definition stage (Define), then the design stage (Design), then the development stage (Develop) and finally the dissemination stage (Disseminate). With these stages, researchers can create and develop independent curriculum teaching modules based on geoboard media and geogebra applications. The effectiveness of the teaching modules designed and developed can be seen through the results of validation and the results of dissemination in SDIT schools. Based on the results of the validation, it can be found that the teaching module that is designed still needs improvement and after improvement, the teaching module is effective and suitable for use in mathematics learning about recognizing the shape of flat building in the first grade and based on the results of the test the teaching module is not only able to overcome students' difficulties in learning mathematics but also increases student activity in learning, This can be seen from the response of students who received a positive response from students after conducting a trial of the independent curriculum module based on geoboard media and geogebra applications.

Abstract

Rendahnya kemampuan numerasi pada materi KPK menunjukkan perlunya bahan ajar yang lebih bermakna. Penelitian ini bertujuan mengembangkan dan menguji efektivitas modul ajar dan LKPD KPK berbasis guided discovery learning dengan media papan bilangan 1–100 untuk siswa kelas V SD. Penelitian menggunakan metode R&D model 4D (Define, Design, Develop, Disseminate) di SDN 02 Koto Tuo dengan subjek 22 siswa. Data diperoleh melalui lembar validasi ahli dan tes hasil belajar (pretest–posttest) yang dianalisis secara deskriptif, uji normalitas Shapiro–Wilk, uji t berpasangan, dan N-Gain. Hasil validasi menunjukkan modul dan LKPD berada pada kategori valid–sangat valid. Nilai rata-rata belajar meningkat signifikan, N-Gain berada pada kategori sedang mendekati tinggi, dan sebagian besar siswa mencapai KKM. Dengan demikian, modul ajar dan LKPD berbasis guided discovery learning dengan media papan bilangan 1–100 dinyatakan layak dan cukup efektif sebagai alternatif bahan ajar numerasi pada Kurikulum Merdeka. Penelitian lanjutan disarankan melibatkan sampel lebih luas serta mengkaji kepraktisan secara kuantitatif.

Abstract

This study aims to develop and evaluate a Problem Based Learning (PBL)-based teaching module and student worksheet (LKPD) to improve second-grade students’ understanding of addition without regrouping. The study is motivated by conceptual difficulties often faced by lower-grade students, who tend to memorize procedures without understanding the relationships among numerical values, concrete representations, and symbolic forms. This research employed a Research and Development (R&D) approach using a simplified Plomp model through preliminary research, development, and evaluation stages. The learning design refers to Arends’ five-phase PBL syntax: problem orientation, organizing learning, guiding inquiry, developing and presenting results, and evaluating the problem-solving process. The findings show that the implementation reached a 96% completion rate in PBL syntax, categorized as “very good.” Student engagement reached 92%, demonstrated through group discussions, manipulation of concrete objects, and presentations. In the individual evaluation, 23 out of 25 students (92%) achieved mastery, while two required remedial support due to errors in counting tens. Additionally, 88% of students successfully transitioned from concrete representation to symbolic notation. Challenges encountered included classroom noise, uneven participation among several students, and limited investigation time; however, these were resolved through simplified teacher instructions and structured guidance. Overall, the PBL-based module and LKPD proved practical, effective, and feasible, and show potential for wider implementation in early-grade mathematics learning to enhance conceptual understanding and collaborative skills.

Abstract

This study aims to develop and validate a teaching module for Mathematics in grade VI elementary school on ratio material using the Merdeka Curriculum with Problem-Based Learning (PBL) approach. The research employed a development model involving expert validation on content, language, and media aspects. Data analysis used Likert scale instruments, showing post-revision validity scores of 90.10% (content), 87% (language), and 91.6% (media), all categorized as highly valid. The module supports meaningful learning, contextual examples, and differentiated assessments, enhancing students' proportional reasoning and numeracy skills for real-life applications
