Abstract

Penelitian ini bertujuan mengembangkan aktivitas pembelajaran berbasis PMR dengan MathCityMap untuk mendukung kemampuan pemecahan masalah matematis siswa SMP. Menggunakan model ADDIE (Analyze, Design, Development, Implementation, Evaluation), penelitian melibatkan 16 siswa kelas VIII MTs Negeri 10 Sleman. Data dikumpulkan melalui wawancara guru, validasi media pembelajaran, tes, dan kuesioner siswa. Hasil penelitian menunjukkan aktivitas pembelajaran dengan MathCityMap yang dikembangkan menggunakan ADDIE. Pada tahap Analyze, dilakukan analisis kebutuhan belajar. Pada tahap Design, dipilih media pembelajaran dan disusun tes kriteria. Pada tahap Development, dilakukan pengembangan, validasi ahli, dan revisi. Pada tahap Implementation, dilakukan uji coba. Pada tahap Evaluation, ditinjau kualitas produk. MathCityMap valid (82,3%), praktis (77,7%), dan cukup efektif (62,25%) mendukung pembelajaran bangun ruang sisi datar.

Abstract

Numeracy is important to develop because it is related to students' ability to solve mathematical problems in everyday life. This research aims to improve students' numeracy and self-confidence through the application of the Problem Based Learning (PBL) learning model. The type of research is classroom action research (CAR) with an adaptation of the Kemmis and Mc Taggart model. The subjects of this research were 30 class VII students at SMP Negeri 1 Depok. The data collection instruments used included a self-confidence questionnaire and numeracy test. Data analysis techniques for self-confidence questionnaires and numeracy test results are averaged, categorized and the gain score value analyzed. The results of this research show that students' numeracy and self-confidence increase after PBL learning. The increase in students' numeracy can be seen from the gain-score of students’ numeracy test from Cycle 1 to Cycle 2. The Problem Based Learning model also increases students' self-confidence based on the increase in categories achieved by students from Cycle 1 to Cycle 2. Therefore, the researcher Others can use the PBL model to increase students' self-confidence and numeracy in other materials.
