Pengembangan Bahan Ajar Berbasis RME Berbantuan Macromedia Flash untuk Meningkatkan Kemampuan Pemecahan Masalah Matematisdan Self-Efficacy Siswa

Abstract

The use of macromedia flash as a learning medium is useful for teachers as an aid in preparing teaching materials and organizing learning. It is hoped that through research on the development of RME-based teaching materials assisted by Macromedia Flash this can be an alternative to realizing a quality learning process and is also expected to improve students' problem-solving skills and self-efficacy. This research has several objectives: (1) To produce RME-based teaching materials assisted by Macromedia Flash to improve students' mathematical problem-solving skills and Self-Efficacy which are valid, practical and effective; and (2) to determine the increase in students' mathematical problem-solving abilities and self-efficacy by using the developed Macromedia Flash-assisted RME-based teaching materials. The type of research conducted is development research. This study used the Thiagarajan 4-D development model and researchers developed teaching materials based on a realistic mathematical approach. The subjects in this study were grade 7th students of East Halongonan One Roof Public Middle School 4 for the 2020/2021 academic year. In the first trial, there were 30 students in grades 7-3 and in the second trial, there were 30 students in grades 7-2.The results showed that: (1) There was an increase in students' mathematical problem solving ability and self-efficacy by using developed Macromedia Flash assisted RME-based teaching materials; and (2) RME-based teaching materials assisted by macromedia flash to improve students' mathematical problem-solving skills and self-efficacy developed in this study already meet valid, practical and effective criteria.

“…Fenomena ini terbukti melalui observasi empiris yang dilakukan oleh peneliti pendahuluan, serta hasil wawancara yang dilakukan dengan para pendidik. Hal ini sesuai dengan penelitian yang menunjukkan bahwa siswa SMP 4 Satu Atap Halongonan Timur memiliki keyakinan yang berada di bawah rata-rata terhadap kemampuan dirinya (Siregar et al, 2023). Observasi dan wawancara mengungkapkan dua kecenderungan utama di kalangan siswa: (1) mereka pasif, menunggu orang lain menanggapi pertanyaan mereka, dan (2) mereka kurang percaya diri ketika mengungkapkan pendapat, biasanya hanya merespons pertanyaan ketika guru menyuruh mereka melakukannya.…”

Pembelajaran Segitiga dan Segiempat Berbasis Pendidikan Matematika Ralistik Indonesia (PMRI) dengan Konteks Kertas Origami

“…Selain itu juga dalam kegiatan pembelajaran masih banyak terdapat penyampaian materi secara langsung oleh guru (Siregar et al, 2023). Pada proses pembelajaran matematika dengan berbagai kegiatan sangat penting untuk memahami konsep sebab dalam pembelajaran matematika harus terstruktur sehingga tidak ada tahapan atau langkah-langkah yang terlewati.…”
