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

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

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%.

Abstract

This study explores fifth-grade students' mathematical thinking processes, specifically how they interpret and solve addition and subtraction problems in story-based contexts. Using a qualitative case study approach, five students from an elementary school in Yogyakarta were examined through interviews, observations, and mathematics problem-solving tasks. The data were analyzed using inductive thematic coding to uncover patterns in computational strategy and conceptual understanding. Results showed that students employed diverse techniques such as horizontal and vertical stacking, semantic and computational sentence transformation, and even-number decomposition. These strategies reflected varying levels of comprehension regarding commutative and associative mathematical properties. Moreover, students who had difficulty translating story problems into mathematical expressions typically showed weak understanding of operational meaning and structure. The study found that most students shifted from semantic to computational forms for ease in calculation. This suggests the need for instructional support to enhance students’ conceptual grasp of operations. Overall, this study provides insights into how mathematical thinking can be developed through contextual learning and supports integrating meaningful problem-solving practices into mathematics education.

Abstract

This study aims to determine the differences between PjBL-based GDL and TCL learning models on students' mathematical communication abilities, examine differences in FI and FD cognitive styles on students' mathematical communication abilities, and investigate the interaction between PjBL-based GDL and TCL learning models and cognitive styles on students' mathematical communication abilities. This study employed a quantitative approach with a quasi-experimental design. The research subjects consisted of fourth-grade students from two elementary schools in Cluster III, Depok District, Sleman, Yogyakarta. Data analysis was conducted through an independent samples t-test and two-way ANCOVA. The results revealed that the PjBL–GDL model had a significant effect on students’ mathematical communication skills (F = 116.75; p < 0.05; η² = 0.522). Significant differences were also found between FI and FD students (F = 46.29; p < 0.05; η² = 0.302). However, no significant interaction was observed between learning models and cognitive styles (p > 0.05), indicating independent effects. These findings imply that the PjBL–GDL model can be implemented inclusively without the need to differentiate instruction based on students’ cognitive styles, making it a practical approach for heterogeneous classrooms. The novelty of this study lies in integrating PjBL and GDL to enhance mathematical communication across diverse learners. It is concluded that PjBL–GDL is effective regardless of cognitive style. Teachers are recommended to apply this model flexibly, while future studies should examine its impact on other skills such as motivation and critical thinking.
