Abstract

Pembelajaran matematika di perguruan tinggi masih didominasi oleh penggunaan lembar kerja siswa konvensional yang kurang interaktif dan belum secara optimal memperkuat pemahaman siswa tentang operasi bilangan. Penelitian ini bertujuan untuk mengembangkan lembar kerja siswa berbasis permainan edukatif Cross Math yang terintegrasi dengan pendekatan Realistic Mathematics Education (RME) dan untuk menguji validitas, kepraktisan, dan efektivitasnya dalam meningkatkan pemahaman konseptual siswa tentang operasi bilangan. Penelitian ini menggunakan metode Penelitian dan Pengembangan dengan model 4D, yang terdiri dari tahap mendefinisikan, merancang, mengembangkan, dan menyebarluaskan. Subjek penelitian adalah mahasiswa Program Studi Pendidikan Matematika di Universitas Muhammadiyah Bangka Belitung. Instrumen penelitian meliputi lembar validasi ahli, kuesioner respons siswa, dan tes pemahaman konseptual dalam bentuk pretest dan posttest. Data dianalisis menggunakan teknik deskriptif kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa lembar kerja yang dikembangkan memenuhi kriteria validitas tinggi dan kepraktisan tinggi. Lebih lanjut, tes efektivitas menunjukkan peningkatan pemahaman konseptual siswa tentang operasi bilangan, dengan penguasaan klasik mencapai 83,33% dan peningkatan yang diamati di semua indikator pemahaman konseptual. Temuan ini menunjukkan bahwa lembar kerja berbasis permainan edukatif Cross Math yang terintegrasi dengan pendekatan RME efektif sebagai bahan pembelajaran alternatif untuk meningkatkan keterlibatan siswa dan pemahaman konseptual dalam pembelajaran matematika.

Abstract

This study aims to explore the potential use of student worksheets (LKM) based on Cross Math with the Realistic Mathematics Education (RME) approach to improve students’ understanding of number operations through set theory. The research employed a preliminary study with a mixed-method approach. Data were collected through questionnaires distributed to 75 mathematics education students at Universitas Muhammadiyah Bangka Belitung who had taken Basic Mathematics courses, as well as interviews with course lecturers. The questionnaire results revealed that the majority of students considered arithmetic operations as an essential topic to master, with a tendency to better understand concepts when linked to real-life experiences. Most students also perceived that learning media, particularly worksheets, are highly supportive in the learning process. Lecturer interviews further indicated that students often face difficulties in understanding algebra, sets, and geometry, which highlights the need for innovative, interactive, and contextual learning media. Based on these findings, Cross Math-based worksheets with the RME approach have the potential to become an alternative learning medium that can increase motivation, strengthen conceptual understanding, and provide a more meaningful learning experience. This study serves as a preliminary foundation for subsequent development stages, namely the production of Cross Math-based worksheets that are valid, practical, and effective for use in mathematics learning at the higher education level.
