Abstract

Comparative Analysis of Elementary Mathematics Textbooks on Geometry in Indonesia and the United States. Objectives: This study aims to describe a comparison between elementary mathematics textbooks from Indonesia and the United States, focusing on geometry content. The analysis covers mathematical content based on Van Hiele’s levels of geometric thinking and Gracins’ framework, including mathematical activities, task complexity levels, response formats, and contextual features. Methods: A qualitative approach was employed, using coding and content recording techniques on Indonesian mathematics textbooks (Matematika SD/MI) and the Go Math! series from the United States across all elementary grade levels. Horizontal and vertical analyses were conducted. Inter-rater reliability was tested using Fleiss’ Kappa via JASP software, yielding high agreement levels ranging from "almost perfect" to "substantial" across all dimensions. Findings: The results indicate that Go Math! has a greater number of pages, emphasizes reasoning and conceptual connections, and is dominated by closed-ended tasks. Indonesian textbooks tend to focus more on geometric shapes and properties, with a stronger presence of realistic contextual applications. Notably, there is no geometry content in Go Math! Grade 6 (2023 edition). Conclusion: This study contributes to the international discourse on textbook design and curriculum policy. The comparison reveals differing instructional approaches to geometry between developing and developed countries. The applicability of the Van Hiele and Gracins’ frameworks across educational contexts is affirmed. Differences in contextual features also highlight the influence of local culture on mathematical content presentation. The absence of geometry in the final elementary grade in the U.S. curriculum points to a potential learning gap. This study recommends the development of more progressive mathematics textbooks that include varied activities, open-ended tasks, and meaningful contexts. It also encourages further comparative research across different content domains as a foundation for global mathematics education reform. Keywords: textbook research, mathematics, geometry, indonesia, united states.

Abstract

Fractions serve as a critical foundation in mathematics education, preparing students for more advanced topics such as algebra and probability. Despite their importance, fractions are often difficult for elementary school students to grasp due to their abstract nature, especially when not taught within meaningful contexts. This study investigates the learning obstacles faced by fifth-grade students in understanding the multiplication and division of fractions. Utilizing a qualitative case study approach, data were collected through tests, interviews, classroom observations, and documentation at Lempuyangwangi Elementary School in Yogyakarta. The analysis revealed three primary categories of learning obstacles: (1) Ontogenic obstacles, including students’ inability to simplify fractions correctly, frequent computational errors, and low motivation in learning mathematics; (2) Didactical obstacles, such as difficulties in interpreting word problems and applying appropriate procedures; and (3) Epistemological obstacles, particularly in understanding and applying the inverse concept required for dividing fractions. These findings highlight the need for more contextually relevant and cognitively aligned instructional strategies. Addressing these obstacles can support the development of more effective teaching approaches to enhance students’ conceptual understanding of fraction operations.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efektivitas pendekatan Realistic Mathematics Education (RME) dibandingkan dengan metode pembelajaran tradisional dalam meningkatkan kemampuan siswa sekolah dasar dalam menyelesaikan soal matematika, dengan mempertimbangkan perbedaan gaya belajar (Visual, auditori, dan kinestetik). Penelitian ini menggunakan metode eksperimen semu dengan rancangan posttest-only control group design. Subjek terdiri atas dua kelompok siswa kelas VI yang masing-masing menerima perlakuan berbeda, yaitu pembelajaran dengan pendekatan RME dan pembelajaran konvensional. Data dianalisis menggunakan ANOVA dua arah untuk mengidentifikasi pengaruh masing-masing variabel, yaitu jenis pendekatan pembelajaran, tipe gaya belajar, serta interaksi di antara keduanya terhadap hasil belajar matematika. Hasil analisis menunjukkan bahwa pendekatan RME secara signifikan lebih unggul dalam meningkatkan kemampuan pemecahan matematika siswa dibandingkan dengan pendekatan konvensional. Selain itu, ditemukan pengaruh signifikan dari gaya belajar, di mana siswa dengan gaya belajar visual dan kinestetik menunjukkan pencapaian yang lebih tinggi dibandingkan siswa dengan gaya belajar auditori. Interaksi antara pendekatan pembelajaran dan gaya belajar juga terbukti signifikan terhadap kemampuan pemecahan soal matematika. Temuan ini menggarisbawahi pentingnya penerapan pendekatan pembelajaran kontekstual yang selaras dengan karakteristik belajar siswa untuk meningkatkan kualitas pembelajaran matematika di tingkat sekolah dasar.

Abstract

This study aims to analyze the ability to think reflectively in problem solving from a gender perspective. The approach used in this study was qualitative descriptive with the aim of describing in depth the differences in reflective thinking patterns between men and women. Data were collected through in-depth interviews and participatory observations involving Yogyakarta State Elementary School students as participants. The data obtained from the tests and interviews analyzed using qualitative descriptive analysis. The results show that women tend to use a more holistic reflective thinking approach that involves evaluating social and emotional impacts and considering long-term solutions. In contrast, men tend to use a more pragmatic approach, focusing on quick and efficient solutions and relying on personal experience in problem solving. These findings showed that there were significant differences between men and women in how they think reflectively, which can affect how they solve problems. Therefore, this study suggests that a more inclusive learning approach be designed to accommodate these differences, in order to improve reflective thinking skills in both genders.

Abstract

During the COVID-19 pandemic, Moodle (Modular Object-Oriented Dynamic Learning Environment) emerged as a leading online learning platform, providing essential support for educational institutions transitioning to remote learning. However, its role as a supplementary tool alongside traditional teaching methods in non-pandemic contexts remains underexplored in academic research. This study aims to investigate the attitudes of higher education student-teachers toward Moodle as an asynchronous online learning platform that enhances traditional classroom learning. The research employed a descriptive-quantitative method, focusing on students from the Teacher Training and Education Faculty, specifically those in the Elementary School Teacher Education Department at Universitas Tanjungpura, Indonesia. Participants were selected through purposive sampling, targeting individuals with experience using Moodle in online and offline learning environments. Data were collected using a structured questionnaire to assess student-teacher attitudes toward Moodle. It underwent a rigorous validation process to ensure the instrument's validity, including expert reviews. The reliability of the questionnaire was assessed through a pilot test conducted with 25 elementary school student-teachers from a state university. The results indicate that most student-teachers have positive attitudes toward Moodle, particularly valuing its effectiveness in enhancing their traditional learning experiences. Despite these favorable views, further research is necessary to develop a more comprehensive understanding of Moodle as a learning management system. Future studies should explore a broader range of educational contexts and levels to better understand the diverse challenges and benefits of applying Moodle in different teaching environments.

Abstract

Abstrak: Kemampuan numerasi siswa Sekolah Dasar di Kabupaten Bantul masih rendah, sebagaimana ditunjukkan data Asesmen Nasional yang mencatat hanya 46,67% siswa di atas batas minimum, serta hanya 20,5% dari 78 guru yang memiliki tingkat numerasi tinggi. Rendahnya kemampuan ini disebabkan oleh pembelajaran yang belum berbasis riset. Temuan ini menunjukkan bahwa kemampuan numerasi siswa dan guru masih di bawah rata-rata dan belum optimal sehingga diperlukan pendampingan untuk guru dalam penyusunan milieu praktik mengajar guna meningkatkan kualitas pembelajaran dan numerasi siswa. Kegiatan ini bertujuan untuk meningkatkan hardskill guru dalam merancang milieu praktik mengajar berbasis riset dan softskill guru dalam menerapkan strategi pengajaran dalam meningkatkan kemampuan numerasi ssiwa. Metode kegiatan meliputi praktik langsung dan FGD penyusunan milieu dengan melibatkan 25 guru SD serta kolaborasi bersama Dinas Pendidikan Pemuda dan Olahrag Kabupaten Bantul Yogyakarta. Evaluasi dilakukan melalui angket untuk menilai pemahaman konsep, observasi praktik penyusunan milieu, serta umpan balik terkait penerapan strategi. Kegiatan ini berhasil meningkatkan kompetensi guru dalam merancang pembelajaran efektif hingga 90%.Abstract: Elementary school students' numeracy skills in Bantul Regency still need to improve, as shown by National Assessment data, which recorded only 46.67% of students above the minimum limit and only 20.5% of 78 teachers had a high level of numeracy. This low ability is caused by learning that still needs to be research-based. This finding shows that the numeracy skills of students and teachers are still below average and not optimal, so mentoring is needed for teachers in compiling teaching practice milieu in order to improve the quality of student learning and numeracy. This activity aims to improve teachers' hard skills in designing research-based teaching practice milieu and teachers' soft skills in implementing teaching strategies to improve students' numeracy skills. The activity methods include direct practice and FGD on compiling a milieu involving 25 elementary school teachers and collaboration with the Bantul Regency Youth and Sports Education Office, Yogyakarta. Evaluation is carried out through questionnaires to assess understanding of concepts, observation of milieu compilation practices, and feedback related to strategy implementation. This activity has succeeded in increasing teacher competence in designing effective learning by up to 90%.
