Abstract

This research is an ADDIE-based research and development. Data on the development process were collected using tools validated by materiel experts, design experts, student response questionnaires and teacher responses. The results of the implementation of the use of textbooks are seen from the student activity sheets and student learning outcomes, in this study using participants from class VIII students of MTs YPI Kuala Enok totaling 28 students with a random sampling technique. The results of this development research are: (1) SMP / MTs mathematics textbooks based on the APOS theory on straight line equation material are declared suitable for use in learning activities based on the validation results of material experts and design experts. Based on the results of student and teacher responses to textbooks, they are ranked very well. (2) The effectiveness of using SMP/MTs mathematics textbooks based on the APOS (Action, Process, Object, Schema) theory of straight line equation material seen from the student activity sheet can be concluded that in the process of learning student activities. In addition, on the basis of the results of all students, the criteria for completeness were achieved, an average score of 85. Thus, from the results of this analysis, it can be concluded that textbooks based on the APOS theory are effective in constructing an understanding of the concept of straight line equations.

Abstract

Kemampuan spasial berperan penting dalam pembelajaran geometri khususnya bangun ruang. Namun, kemampuan spasial siswa masih tergolong rendah. Kemampuan spasial dapat ditingkatkan dengan inovasi bahan ajar yang adaptif teknologi melalui augmented reality. Augmented reality dapat menampilkan bentuk 2D maupun 3D. Penelitian ini bertujuan menghasilkan dan menguji kualitas buku saku berbasis augmented reality pada materi bangun ruang sisi lengkung untuk meningkatkan kemampuan spasial siswa. Penelitian ini merupakan penelitian pengembangan menggunakan model Plomp yang terdiri dari fase investigasi awal, desain, realisasi/konstruksi, tes, evaluasi, revisi, dan implementasi. Satu orang guru matematika SMP Negeri 17 Kota Jambi dan siswa kelas IX G SMP Negeri 17 Kota Jambi berjumlah 38 siswa sebagai subjek penelitian. Hasil penelitian diperoleh: 1) rata-rata kevalidan  buku saku 85,78 % (sangat valid), 2) rata-rata kepraktisan buku saku 85,74% (sangat praktis), 3) keefektifan buku saku dari rata-rata lembar observasi aktivitas siswa pada uji lapangan 82,21%, dari ketuntasan tes hasil belajar 81,57% (sangat efektif) dan tes kemampuan spasial diperoleh 12 siswa berkemampuan spasial sedang dan 26 siswa berkemampuan spasial tinggi. N-Gain diperoleh 62,6% (cukup efektif). Berdasarkan hasil penelitian disimpulkan bahwa buku saku berbasis augmented reality pada materi bangun ruang sisi lengkung memenuhi kriteria valid, praktis, dan efektif sehingga layak digunakan sebagai media pembelajaran.Spatial ability plays an important role in learning geometry, especially spatial figures. However, students' spatial abilities are still relatively low. Spatial abilities can be improved by innovation in technology-adaptive teaching materials through augmented reality. Augmented reality can display 2D or 3D shapes. This research aims to produce and test the quality of an augmented reality-based pocket book on curved-sided geometric material to improve students' spatial abilities. This research is development research using the Plomp model which consists of initial investigation, design, realization/construction, test, evaluation, revision, and implementation phases. One mathematics teacher at SMP Negeri 17 Jambi City and 38 students in class IX G of SMP Negeri 17 Jambi City were the research subjects. The research results obtained: 1) the average validity of the pocketbook was 85.78% (very valid), 2) the average practicality of the pocketbook was 85.74% (very practical), 3) the effectiveness of the pocketbook was based on the average activity observation sheet students in the field test were 82.21%, from the completion of the learning result test was 81.57% (very effective) and in the spatial ability test, 12 students had moderate spatial ability and 26 students had high spatial ability. N-Gain was obtained at 62.6% (quite effective). Based on the research results, it was concluded that the pocketbook based on augmented reality on curved-sided spatial material meets the criteria of being valid, practical, and effective so it is suitable for use as a learning medium.

Abstract

Augmented Reality merupakan teknologi yang mampu menggabungkan dunia nyata dan virtual dengan menampilkan objek tiga dimensi (3D) pada media kamera gawai sehingga pada layar gawai terlihat objek 3D yang seperti terlihat ada pada dunia nyata. Penelitian ini bertujuan untuk mengembangkan dan menguji kelayakan modul berbasis Augmented Reality yang dapat meningkatkan kemampuan spasial siswa. Penelitian ini adalah penelitian pengembangan dengan model pengembangan Plomp yang terdiri dari: Investigasi Awal; Desain; Realisasi; Tes, Evaluasi, dan Revisi. Instrumen yang digunakan yaitu lembar validasi ahli, lembar observasi, pedoman wawancara, angket respon guru dan siswa, tes hasil belajar, pretest dan posttest kemampuan spasial siswa. Jenis data yaitu data kualitatif dan data kuantitatif. Analisis data yang dilakukan yakni analisis data validasi tim ahli, analisis data kepraktisan, dan analisis data keefektifan. Adapun hasil penelitian menunjukkan skor ahli materi sebesar 91, 53% dan skor ahli desain sebesar 90,53% tergolong kategori sangat valid. Modul juga telah dinyatakan praktis dilihat dari skor angket respon guru sebesar 80,00% tergolong kategori praktis, dan skor angket pada uji coba kelompok kecil sebesar 84,26% serta pada uji lapangan sebesar 84,38% tergolong kategori sangat praktis. Keefektifan ditunjukan dengan 83,33% siswa tuntas pada tes hasil belajar, dan hasil perhitungan N-Gain terdapat 11 orang siswa mengalami peningkatan kemampuan spasial sedang dan 13 orang siswa mengalami peningkatan kemampuan spasial tinggi. Berdasarkan hasil penelitian dapat disimpulkan bahwa modul berbasis Augmented Reality untuk materi bangun ruang sisi datar yang telah dikembangkan layak digunakan sebagai bahan ajar pembelajaran.
