Pengembangan E-LKS Model Guided Discovery Materi Bangun Ruang Sisi Datar Untuk Memfasilitasi Kemampuan Pemecahan Masalah Matematis Siswa Kelas VIII SMP/Mts
The purpose of this study is to produce Electronic-based Student Worksheets (LKS-E) using a Guided Discovery approach on Polyhedron Material Based that are valid, practical, and have a potential effect on the Mathematical Problem Solving Ability (KPMM) of junior high school students/MTs. The research method used in this research is Research and Development using a 4-D development model consisting of four stages, namely Define, Design, Development, and Disseminate. Data collection techniques used include validation questionnaires, student response questionnaires, and documentation. This research involved students of class VIII MTs YASMI and IX MTs YASMI. The results showed that LKS-E has been valid from the quality of presentation, technical requirements, didactic requirements and construction requirements as well as KPMM aspects with very valid criteria, based on expert comments at the Expert Review and One-to-One stages. Next, the implementation of LKS-E at the Small Group and Field Test stage shows the practicality of LKS-E with very practical criteria. This can be seen from LKS-E which is easy to read, and easy to use and LKS-E can add enthusiasm to learning. The conclusion is that LKS-E uses a Guided Discovery approach to Polyhedron Material Based to facilitate KPMM for junior high school students and has been valid and practically used in the learning process.
