Development of Student Worksheets with Discovery Learning Models Based on Augmented Reality in Chemical Bonding Materials to Increase Learning Motivation and Learning Outcomes

Abstract

This research aims to: (1) produce student worksheets with an augmented reality-based discovery learning model on chemical bond material that is appropriate for increasing student motivation and learning outcomes; (2) determine the effectiveness of Student Worksheets with augmented reality-based discovery learning models on chemical bond material in increasing student motivation and learning outcomes. This development research uses a 4D development model including the Define, Design, Development and Disseminate stages. The trial was carried out on Grade X Science students at SMA Sejahtera 1 Depok with a quasi-experimental design, nonequivalent control group design model. The research instruments used were validation sheets, learning motivation questionnaires and learning outcomes questions. The research results show that: (1) student worksheets with augmented reality based discovery learning model on chemical bonding material that has been developed has very decent quality, which can be proven by the results of the average validation value by material experts of 3.926, media experts of 3.969 and student responses of 3.93; (2) student worksheets with a discovery learning model based on augmented reality is effective in increasing student motivation and learning outcomes with the MANOVA test which obtained a significance value of 0.000 and had an effective contribution of 23.3%.Penelitian ini bertujuan untuk: (1) menghasilkan lembar kerja siswa dengan model pembelajaran penemuan berbasis augmented reality pada materi ikatan kimia yang sesuai untuk meningkatkan motivasi dan hasil belajar siswa; (2) mengetahui efektivitas Lembar Kerja Siswa dengan model Discovery Learning berbasis augmented reality pada materi ikatan kimia dalam meningkatkan motivasi dan hasil belajar siswa. Penelitian pengembangan ini menggunakan model pengembangan 4D meliputi tahap Define, Design, Development dan Disseminate. Uji coba dilakukan pada siswa kelas X IPA SMA Sejahtera 1 Depok dengan desain quasi eksperimen model nonequivalent control group design. Instrumen penelitian yang digunakan adalah lembar validasi, angket motivasi belajar dan soal hasil belajar. Hasil penelitian menunjukkan bahwa: (1) Lembar kerja siswa dengan model pembelajaran penemuan berbasis augmented reality pada materi ikatan kimia yang dikembangkan mempunyai kualitas sangat baik, dibuktikan dengan hasil rata-rata nilai validasi ahli materi sebesar 3,926, media ahli sebesar 3,969 dan respon siswa sebesar 3,93; (2) lembar kerja siswa dengan model Discovery Learning berbasis augmented reality efektif meningkatkan motivasi dan hasil belajar siswa dengan uji MANOVA memperoleh nilai signifikansi sebesar 0,000 dan mempunyai sumbangan efektif sebesar 23,3%.
