Abstract

Program Pengabdian kepada Masyarakat (PkM) ini dilaksanakan untuk mendukung guru dalam mengimplementasikan pembelajaran matematika yang menyenangkan pada materi pecahan melalui penggunaan media Built-in Definition of Fraction (BDF). BDF merupakan media manipulatif yang dirancang untuk membantu pembelajaran pecahan melalui representasi visual dan aktivitas eksploratif. Kegiatan dilaksanakan di SDN 149 Palembang dengan melibatkan 17 guru peserta. Tahapan kegiatan meliputi persiapan, sosialisasi, pelatihan, pendampingan, implementasi, dan evaluasi. Data dikumpulkan melalui angket kebutuhan awal (needs assessment) serta instrumen evaluasi yang terdiri atas penilaian diri guru (self- assessment) dan angket persepsi manfaat pelatihan. Data penilaian diri dianalisis secara deskriptif menggunakan skor rata-rata dan kategori penilaian. Hasil evaluasi menunjukkan bahwa guru memiliki tingkat pemahaman dan keterampilan yang sangat baik dalam menggunakan media BDF pada pembelajaran pecahan dengan rata-rata skor sebesar 4,38 yang berada pada kategori Sangat Baik. Selain itu, guru juga memberikan persepsi positif terhadap manfaat pelatihan dalam mendukung penggunaan media pembelajaran pada materi pecahan. Hasil kegiatan menunjukkan bahwa media BDF dapat dijadikan alternatif media pembelajaran untuk mengimplementasikan pembelajaran matematika yang lebih konkret, interaktif, dan menyenangkan di sekolah dasar.

Abstract

This study addresses the challenge of students limited conceptual understanding of fractions by developing a physical manipulative called the Built-in Definition of Fraction (BDF). Using design research developmental studies, data were collected through written tests, questionnaires, and interviews. A total of 41 fifth-grade students participated in the study. The BDF and its accompanying student worksheet integrate dual visual-symbolic representations, that link each concrete action to its corresponding fraction notation and scaffold students in constructing their own understanding of fractions, offering a new approach to using fraction manipulatives. Validation results show that the manipulative is valid, practical, and effective in supporting student understanding of basic fraction concepts, equivalent fractions, and same-denominator addition, even with minimal teacher guidance. Student performance was high across visual-concrete tasks. However, a noticeable gap emerged in unlike-denominator addition between visual concrete performance (88%) and formal-symbolic procedures (77%). This finding highlights the need for additional scaffolding to help students transition more smoothly from concrete representations to abstract symbolic reasoning.

Abstract

Procedural fluency is a crucial component of mathematical proficiency, enabling students to solve problems accurately and efficiently. This study aimed to describe the procedural fluency of tenth-grade students in solving Three-Variable Linear Equation Systems (SPLTV) through Discovery Learning assisted by  Photomath. This study employed a descriptive qualitative approach, involving 39 tenth-grade students from a senior high school in Palembang. Three participants were selected as main participants based on their ability levels: high, moderate, and low. Data were collected through procedural fluency tests and interviews. The use of these two techniques provided a more comprehensive picture of students' procedural fluency. The results showed variation in students' procedural fluency levels. Students with high abilities were able to choose and utilise the appropriate solution procedures, apply the steps systematically, and modify or correct the procedures when they found inconsistencies in the results. Students in the moderate category can choose the correct method and attempt to recheck the solution results, but are not yet fully able to correct the errors found. Meanwhile, students with low abilities are not yet able to apply solution procedures, nor modify or correct procedures, even when errors occur in the solution.
