Abstract

ABSTRAK Penelitian ini bertujuan untuk mengembangkan bahan ajar. Produk yang dihasilkan adalah bahan ajar kontekstual berorientasi kemampuan representasi matematis pada materi bangun datar untuk peserta didik kelas VII sebagai inovasi dan solusi permasalahan pemahaman peserta didik terhadap materi bangun datar serta dapat menambah pengetahuan dan wawasan keterkaitan materi dengan kemampuan representasi matematis peserta didik. Penelitian ini menggunakan metode Reserech and Development (R&D) dengan model ADDIE yang lima tahapan pengembangan, yaitu Implementation, and Analysis, Evaluation. Design, Subjek Development, penelitian dan pengembangan ini adalah peserta didik kelas VII di SMPN 1 Gunung Pelindung. Teknik pengumpulan data yang digunakan adalah wawancara, angket validasi, dan angket kemenarikan. Hasil uji kelayakan oleh validator ahli materi 3,71, dan hasil uji validator ahli media 3,73 dengan kriteria “layak”. Uji respon kemenarikan oleh peserta didik pada uji kelompok kecil 3,39 dan pada uji kelompok besar 3,31 dengan kriteria “sangat menarik”. Pada uji efektivitas kemampuan representasi matematis diperoleh skor uji effect size sebesar 0,82 dengan kategori “tinggi”. Oleh karena itu, dapat disimpulkan bahwa bahan ajar kontekstual berorientasi kemampuan representasi matematis materi bangun datar menarik dan dapat digunakan dalam pembelajaran. Kata Kunci: Bahan ajar, Kontekstual, Kemampuan Representasi Matematis. iii ABSTRACT This research aims to develop teaching materials. The product produced is contextual teaching materials oriented towards mathematical representation skills in flat building materials for grade VII students as an innovation and solution to students' understanding of flat building materials and can increase knowledge and insight into the relationship of materials with students' mathematical representation skills. This research uses the Reserech and Development (R&D) method with the ADDIE model which has five stages of development, namely Analysis, Design, Development, Implementation, and Evaluation. The subject of this research and development is grade VII students at SMPN 1 Gunung Pelindung. The data collection techniques used were interviews, validation questionnaires, and attractiveness questionnaires. The results of the feasibility test by the material expert validator were 3.71, and the results of the media expert validator test were 3.73 with the "feasible" criteria. The attractiveness response test by students in the small group test was 3.39 and in the large group test was 3.31 with the criterion of "very interesting". In the effectiveness test of mathematical representation ability, an effect size test score of 0.82 was obtained with the category of "high". Therefore, it can be concluded that contextual teaching materials are oriented towards the mathematical representation of flat building materials that are interesting and can be used in learning. Keywords: Teaching materials, contextual, mathematical representation.
