Pengembangan Perangkat Pembelajaran Matematika Menggunakan Model Problem Based Learning Untuk Memfasilitasi Kemampuan Pemecahan Masalah Matematis Pada Materi Segiempat Dan Segitiga Kelas VII SMP/Mts
This research aims to produce valid and practical learning tools, namely Syllabus, RPP, and LKPD on the material of Quadrilateral and Triangle for class VII SMP. This research is motivated by the importance of learning tools that can facilitate students' mathematical problem solving abilities. This research use 4D model which consists of 4 stages were definition, design, development, and dissemination. The learning tools have been validated by 3 validators and revised according to the validator's suggestions. The average results of the validation of the syllabus, RPP, and LKPD is 3.55; 3.63 ; and 3.62 with a very valid category. Small group trials were conducted on 6 students with heterogeneous abilities. The average small group trial result for student worksheet is 3.68 with a very practical category covering aspects of appearance, content and ease of use with a sequential score 3.64; 3.61; and 3.66. Learning devices using Problem Based Learning on the material of Quadrilateral and Triangle for class VII SMP have met the valid and practical criteria.
