Pengembangan Perangkat Pembelajaran Berbasis Model Problem Based Learning Pada Materi Sistem Persamaan Linear Dua Variabel Untuk Memfasilitasi Kemampuan Pemecahan Masalah Matematis Peserta Didik Kelas VIII SMP/MTS
One of the main focuses of mathematics learning objectives is that students master mathematical problem solving skills (KPMM), but it is known that KPMM of students is still quite low and teacher learning tools cannot be said to facilitate this ability. This research is intended to produce learning tools consisting of syllabus, lesson plans and LKPD based on Problem Based Learning to facilitate student’s mathematical problem solving abilities on valid and practical two-variable linear equation system material. The development model used is a 4-D model (Define, Design, Develop and Disseminate). The learning device was validated by three validators and evaluated one by one to see the legibility of the student worksheets. The overall results of the validation analysis show that the product developed meets the valid criteria with an average percentage of syllabus 88.43%, RPP 90.90% and LKPD 90.58%. The valid LKPD was then tested in small groups of 10 students. The test results obtained an average of 3.57 with a very practical category. The results of data analysis show that the developed learning tools can facilitate students' mathematical problem solving abilities and can be used during the learning process.
