Abstract

The purpose of this study was to develop interactive videos to facilitate numeracy and produce quality interactive video-based learning media products in terms of validity, practicality, and effectiveness. This research is a research and development study using the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The subjects of this research were 31 students of class VIII F Junior High School 1 Depok Yogyakarta. Data collection techniques using validity questionnaires, numeracy tests, and teacher and student practicality questionnaires. Data from validation questionnaires, tests, and practicality questionnaires were analyzed quantitatively by calculating the average value. The results of this study are 1) The development of interactive videos using the ADDIE model. In the analysis stage, based on teacher interviews, students have difficulty understanding numeracy questions, the Pythagorean theorem material is a difficult topic, and teachers never used interactive videos in learning. At the design stage, researchers designed three videos using the Edpuzzle application. At the development stage, the learning product results were validated by three experts and revised according to the expert's suggestions. At the implementation stage, researchers conducted a trial of four meetings using the guided discovery model. In the evaluation stage, the product was valid, practical, and effective. 2) The product gets very valid results, in terms of media getting 91.25% and material getting 93%. Products get effective results from the numeracy test results as many as 29 students (93.5%) completed the minimum criteria (75). The practical product is seen from the results of the student response questionnaire to the media getting 85.8% and the teacher response questionnaire to the product getting 80%.

Abstract

Hasil PISA menunjukkan bahwa skor literasi matematika siswa Indonesia secara konsisten berada di bawah rata-rata negara peserta OECD, sehingga perlu perhatian lebih dari guru dan siswa. Tujuan dari penelitian ini untuk mendeskripsikan persepsi guru terhadap literasi matematika. Penelitian ini menggunakan metode survei dengan melibatkan 181 guru matematika SMP di Yogyakarta, dengan teknik voluntary sampling. Instrumen angket digunakan untuk mengetahui pemahaman guru dan pentingnya literasi matematika, serta kualitas literasi matematika siswa. Kesimpulan penelitian ini yaitu 1) sebanyak 71% guru telah mengenal konsep literasi matematika, namun 39% guru masih merasa ragu-ragu atau belum mengenal; 95% guru setuju bahwa literasi matematika penting dikembangkan di sekolah; hanya 38% guru yang mengetahui kualitas literasi matematika siswa. 2) Tantangan dalam pengembangan literasi matematika dari faktor guru adalah pemahaman dan pentingnya pengembangan literasi matematika, serta banyak guru belum mengetahui kualitas literasi matematika siswa, kesulitan dalam mengklasifikasikan konten literasi matematika. Peluang untuk mengatasinya melalui upaya pemberian contoh pembelajaran literasi dari pemerintah, penggunaan soal diagnostik seperti AKM, integrasi literasi matematika dalam berbagai mata pelajaran, penerapan pembelajaran berbasis masalah dan proyek, lingkungan belajar yang mendukung, pemodelan pemecahan masalah, pembelajaran kontekstual, inkuiri, soal berbasis budaya, dan pemanfaatan media pembelajaran interaktif.
