Abstrak. Salah satu faktor penyebab pembelajaran matematika di SMPLB berjalan kurang maksimal adalah pengunaan bahan ajar. Bahan ajar yang digunakan oleh guru dalam pembelajaran pada anak-anak tunarungu di SMPLB di Kota Kupang masih menggunakan bahan ajar yang sama dengan siswa normal. maka perlu adanya bahan ajar yang sesuai dengan kebutuhan dan karakteristik mereka. Penelitian ini bertujuan untuk menghasilkan sebuah buku matematika khusus untuk anak-anak tunarungu, yang berbasis pada visualisasi dan realistik. Metode yang digunakan adalah metode pengembangan dengan model 4D rancangan Thaiagaradjan dimana terdiri dari empat tahap yaitu, pendefinisian (define), perancangan (design), pengembangan (develop), dan penyebaran.Instrumen yang dikembangkan dalam penelitian ini terdiri atas enam macam, yakni (1) lembar validasi bahan ajar, (2) lembar keterbacaan bahan ajar, (3) lembar observasi aktivitas guru, (4) lembar observasi aktivitas anak-anak tunarungu, (5) angket respon anak-anak tunarungu dan (6) lembar tes tulis. Indicator penilaian dari penelitian pengembangan ini meliputi valid, praktis dan efektif. Hasil analisis menunjukkan bahan ajar yang dikembangkan memenuhi kriteria valid, praktis dan efektif, sehingga bahan ajar tersebut berkulaitas baik dan dapat digunakan dalam pembelajaran matematika bagi siswa SMPLB Kelas VII.
This Community Service aims to train teachers in conducting Classroom Action Research and assist them in writing scientific articles resulting from CAR. The implementation of this training and mentoring activity was carried out in a blended (online and offline) manner which was attended by 55 teachers with details: 11 Kindergarten teachers, 21 teachers at the elementary school level, 12 teachers at the junior high school level, and 11 teachers at the elementary school level. High School level. Based on the results of observations and discussions with partners, the Community Service Team carried out assistance activities in two stages, namely: 1) strengthening the concept of CAR and Scientific Work; and 2) assistance in writing CAR scientific papers. The output of this activity is an increase in the knowledge and skills of teachers in doing CAR. Based on the results of the evaluation carried out, the teachers felt very helpful with this training and mentoring activity. In addition to increasing teachers' knowledge of CAR concepts, this activity also improves the skills of teachers in designing and implementing CAR through useful activities, setting goals and benefits, making theoretical frameworks, selecting methods, compiling instruments, collecting and analyzing data, and writing articles
How to Build Mathematical Abilities in Deaf Students? A Grounded Theory. Objective: This study aims to produce a conceptual model as a strategy for building mathematical abilities in deaf students. Methods: This is qualitative research with a grounded theory design involving 45 deaf students from four middle schools in Indonesia. Findings: The results of the data analysis at the open coding stage obtained five categories of visual, feeling, understanding, learning experience, and habits in learning mathematics. At the axial coding stage, mathematical understanding was used as the core category. While at the selective coding stage, a conceptual model was built where each category contributes to building mathematical abilities. Conclusion: That efforts are crucial to develop the mathematical abilities of deaf students comprehensively. This can be done by visualizing the problems, connecting the problems with the student environment, providing learning experiences with various questions, giving motivation, and increasing self-confidence using praise and more attention from parents or teachers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
