Pengembangan Bahan Ajar Matematika untuk Meningkatkan Minat Belajar dan Kemampuan Pemecahan Masalah Matematis Siswa SMA

The study is set against background by the importance of the materials that could facilitate students to study wherever and whenever. The study developed a product of a mathematical pocketbook intended to increase the interest in learning and increases the capability of mathematical problem solving. This research’s type is Research and Development (R&D) with the Borg & Gall development model to the 7 stages. Product assessments are made by experts and students. Experts who assess the product are mathematicians, educationists and media experts. As for the subject of this research are the 24 students of XI grades from SHS 8 Tangerang, SHS 2 Banjar, and SHS 1 Merawang. Product assessments and learning interest assessment use non-test instruments in the form of angkets, and assessments of mathematical problem solving using test instruments by giving pretests and posttests. Based on data analysis and study, it could be concluded: 1) Designing and building a mathematical pocketbook that includes both a desire for learning and a ability for mathematical problem solving; 2) Products made ready to be used for math or redeveloped on further research; 3) There is an increase in students’ interest in learning by means of high interpreting; 4) There is an increased mathematical problem solving capability with a moderate interpretation.
