Pengembangan Perangkat Pembelajaran Matematika Berbasis Problem Based Learning Untuk Memfasilitasi Kemampuan Pemecahan Masalah Matematis Siswa Kelas XII SMA Pada Materi Jarak Dalam Ruang
This research is a development research (R&D) that produces a
product in the form of a Problem Based Learning-based learning device that
meets valid and practical requirements to facilitate the mathematical problem
solving ability of class XII SMA students on the material of Indoor Distance. The
development model used is a 4D model, which consists of four stages, namely: (1)
Define; (2) Design; (3) Develop; and (4) Disseminate. The data collection
instruments in this study were observation sheets, interview sheets, validation
sheets and student response questionnaires. The data analysis technique used is
validity analysis and practicality analysis. The learning tools in this study were
syllabus, lesson plans and LAS which had been validated by three validators and
small group trials were conducted on six students of SMA N 12 Pekanbaru to see
the practicality of the developed LAS. The results showed that the learning tools
developed in the very valid category with an average value for the syllabus of
3.95, the average value for lesson plans of 3.91, the average value for LAS 3.83
and the very practical category with the average value is 3.49.
