Digital Flipbook-Based Mathematics Teaching Materials using RME Approach to Improve Mathematical Problem-Solving Ability

Abstract

Abstract: Digital Flipbook-Based Mathematics Teaching Materials using RME Approach to Improve Mathematical Problem-Solving Ability. This research aims to determine the validity, practicality, and effectiveness of flipbook-based statistics teaching materials using realistic mathematics education (RME) approach in improving the mathematical problem-solving abilities of class XI AKL students at SMK N 1 Karanganyar. This research and development uses a 4D model. The assessment of the development of teaching materials is based on the validity and practicality aspects, while the assessment of mathematical problem-solving abilities is based on the effectiveness aspect. Data were collected through material expert and media expert validation sheets for validity aspects, teacher and student response questionnaires for practical elements, and experimental class and control class student answer sheets for effectiveness aspects. Material and media experts assessed the validity aspect, and experimental class students and teachers evaluated the practicality aspect. The effectiveness aspect was by looking at the average post-test score for the experimental and control classes via the t-test. The assessment results show that the teaching materials developed are valid, practical, and effective.

Keywords: teaching materials, realistic mathematics education, research and development

Abstrak: Bahan Ajar Matematika Berbasis Flipbook Digital Menggunakan Pendekatan RME untuk Meningkatkan Kemampuan Pemecahan Masalah Matematika. Tujuan penelitian ini untuk mengetahui kevalidan, kepraktisan, dan keefektifan bahan ajar statistika berbasis flipbook menggunakan pendekatan realistic mathematics education (RME) untuk meningkatkan kemampuan pemecahan masalah matematis siswa kelas XI AKL SMK N 1 Karanganyar. Penelitian dan pengembangan ini menggunakan model 4D. Penilaian pengembangan bahan ajar berdasarkan aspek kevalidan dan aspek kepraktisan, sedangkan penilaian kemampuan pemecahan masalah matematis dengan aspek keefektifan. Pengambilan data melalui lembar validasi ahli materi dan ahli media untuk aspek kevalidan, angket respon guru dan siswa untuk aspek kepraktisan, sedangkan lembar jawab siswa kelas eksperimen dan kelas kontrol untuk aspek keefektifan. Aspek kevalidan dinilai oleh  ahli materi dan ahli media, aspek kepraktisan dinilai siswa kelas eksperimen dan guru, lalu aspek keefektifan dengan melihat rerata nilai posttest kelas eksperimen dan kelas kontrol melalui uji t. Hasil penilaian menunjukkan bahan ajar yang dikembangkan valid,  praktis, dan efektif.

Kata kunci: Bahan ajar, pendidikan matematika realistik, penelitian dan pengembangan.
