Abstract

Augmented Reality (AR)-based learning media have demonstrated potential in enhancing the understanding of abstract chemical concepts, such as chemical equilibrium. This study aims to evaluate the practicality and effectiveness of AR-integrated learning media previously validated in an earlier study. A pre-experimental method with a one-group pretest–posttest design was employed. Practicality testing involved 9 students and 2 chemistry teachers at SMA Negeri 1 Tiumang, while effectiveness was assessed based on the improvement of student learning outcomes using N-Gain analysis and t-test. The sample was selected through purposive sampling, and data collection was conducted at SMA Negeri 1 Koto Baru. The results indicate that the media were rated as highly practical by both teachers (86%) and students (81%), with an N-Gain score of 0.49, classified as moderate. The t-test revealed a significant difference between pretest and posttest scores. Thus, the AR learning media are considered practical and effective, contributing positively to chemistry instruction, particularly in the topic of equilibrium shift.

Abstract

In improving the quality of learning, it is necessary to develop a learning design that can facilitate the characteristics of students. The didactical design can facilitate the characteristics of students through sharing and jumping tasks. Sharing task is used to facilitate slow learner while jumping task is used to facilitate fast learner. Jumping task is not only beneficial for students with high academic ability, but also provides benefits for students with low academic ability. The purpose of this study is to develop the didactical design based on sharing and jumping tasks to enhance learning quality on the topic of reaction rate low. The research method used is didactical design research (DDR). Didactical design consisted of three steps i.e. (a) analysis of didactical situation before learning (prospective), (b) analysis of didactical situation during learning (metapedadidactical), and (c) analysis of didactical situation after learning (retrospective). The data was collected by test, observation, interview, documentation and recording (audio and video). The result showed that the didactical design on the topic of reaction was valid

Abstract

Penerapan pembelajaran berkelompok berbantuan LKPD dengan model pembelajaran tertentu belum mampu memaksimalkan keterlibatan dan keaktifan peserta didik selama belajar karena cenderung hanya mengandalkan teman kelompoknya. Penelitian ini dilakukan sebagai upaya memperbaiki kualitas pembelajaran kimia dari segi keaktifan peserta didik melalui penggunaan pembelajaran kooperatif tipe Teams Game Tournament (TGT) berbantuan permainan Choose Take Answer (CTA). Penelitian dilakukan terhadap 33 peserta didik kelas X SMA pada bulan Mei selama dua siklus. Setiap siklus meliputi beberapa tahapan yaitu perencanaan, pelaksanaan, observasi, dan refleksi. Setiap rangkaian kegiatan penelitian dilakukan secara kolaboratif bersama dosen pembimbing, guru kimia, dan rekan sejawat. Lembar observasi digunakan untuk mencatat aktivitas belajar peserta didik yang meliputi aktivitas belajar dasar (mengamati, menanya/mencoba, dan mencari) dan aktivitas belajar lanjut (berdialog, mengkomunikasikan, dan berkolaborasi) sebagai indikator keaktifan peserta didik selama tindakan. Data yang diperoleh dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan keaktifan peserta didik pada pembelajaran kimia pada siklus I sebesar 50,5% (kategori sedang) dan siklus II sebesar 72,1% (kategori sedang). Peningkatan keaktifan terjadi secara signifikan mulai dari sebelum tindakan, tindakan siklus I, hingga tindakan siklus II dengan besar kenaikan dari keadaan awal sebesar 31,8%. Hasil ini menunjukkan keaktifan belajar peserta didik pada pembelajaran kimia dapat ditingkatkan melalui penerapan pembelajaran kooperatif TGT berbantuan permainan CTA, sehingga dapat diterapkan pada pembelajaran di sekolah sebagai alternatif solusi untuk meningkatkan aktivitas peserta didik.
