Pengembangan Lkpd Berbasis Rme Materi Bangun Ruang Sisi Datar Untuk Memfasilitasi Kemampuan Pemecahan Masalah Matematis Peserta Didik Kelas VIII SMP/MTs
Students mathematical problem solving abilities (KPMM) show that they are still low. One of the contributing factors is that the learning process is not yet optimal, which is indicated by the lack of learning support facilities in the form of student worksheets (LKPD). This research aims to produce LKPD with the RME approach on flat-sided building material that is valid and practical to facilitate students' KPMM. The development model used is the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The prepared LKPD was validated by 3 validators and revised according to the validators' suggestions. The small group trial subjects were six heterogeneous class IX students of SMP N 2 Pekanbaru and 38 IX students of SMP N 2 Pekanbaru as large group trial subjects. The instruments used include: (1) LKPD validation sheet and (2) student response questionnaire to the LKPD. The validation results from three validators show that the LKPD is very valid with an average score of 3,65. The practicality of LKPD shows an average percentage in small group trials of 85,88% with very practical criteria and in large group trials 89,61% with very practical criteria. LKPD with the RME approach on flat-sided geometric material is very valid and practical for facilitating students' mathematical problem solving abilities.
