Abstract

This research aims to determine students' mathematical problem solving abilities in learning using a generative learning model (Generative Learning) with puzzle props using Pythagorean theorem material in class VIII MTsN 11 Tabalong. This type of field research with experimental methods and a quantitative descriptive research approach is used to collect data using tests, namely problem-solving ability tests which have been tested for validity by expert validators. The sampling technique is purposive sampling, namely classes VIII B and VIII C. Data collection techniques include: test methods, documentation and interviews. The research results show: (1) The mathematical problem solving abilities of students in the experimental class with a class average score of 73.38 are in the good category. (2) The students' mathematical problem solving abilities in the control class with a class average score of 63.19 are in the sufficient category (3) There is a significant difference between students' mathematical problem solving abilities in learning with and without using generative learning models. ) with puzzle teaching aids on Pythagorean theorem material in class VIII MTsN 11 Tabalong.

Abstract

Pembelajaran matematika pada siswa tunagrahita seringkali terkendala oleh kesenjangan antara materi abstrak dan kebutuhan visualisasi konkret, khususnya pada operasi penjumlahan. Penelitian ini bertujuan mengembangkan media video animasi bergerak sebagai intervensi visual untuk menjembatani pemahaman konsep tersebut, sekaligus menguji kelayakannya. Menggunakan model pengembangan Research and Development (R&D) 4D (Define, Design, Develop, Disseminate), penelitian melibatkan validasi ahli serta uji coba terbatas pada siswa kelas XII di SLB Negeri Kota Banjarbaru. Hasil penelitian menunjukkan media memenuhi kriteria kelayakan unggul. Uji validitas ahli materi memperoleh indeks 0,91 (Sangat Valid) dan ahli media sebesar 0,75 (Valid). Tingkat kepraktisan dinilai sangat tinggi dengan persentase respon guru 86% dan siswa 83,33%. Selain itu, media terbukti efektif meningkatkan pemahaman konsep, ditunjukkan oleh capaian hasil belajar rata-rata siswa sebesar 90 yang melampaui KKM sekolah (75). Penelitian ini menawarkan kebaruan dalam penyediaan media berbasis teknologi yang adaptif dan solutif bagi hambatan belajar siswa disabilitas intelektual.
