PENGEMBANGAN LKPD BERBASIS CONNECTING, ORGANIZING, REFLECTING AND EXTENDING (CORE) UNTUK MEMFASILITASI KEMAMPUAN PEMECAHAN MASALAH MATEMATIS PADA MATERI BANGUN DATAR (SEGITIGA DAN SEGI EMPAT) SISWA KELAS VII UPT SMP NEGERI 32 BANDAR LAMPUNG
Keywords:
LKPD, CORE, ability to solve math problemsAbstract
This research was conducted to develop LKPD based on Connecting, Organizing, Reflecting and Extending (CORE) to facilitate mathematical problem solving abilities on flat shapes (triangles and rectangles) for class VII students of SMP Negeri 32 Bandar Lampung. Research and Development (R&D) is the category of development research used, and the development model used is Analysis, Design, Development, Implementation and Evaluation. Based on validation data, media experts obtain an average score of 4.38, linguists obtain an average score of 4.71, and material experts obtain an average score of 4.69 using the "Valid" criterion. The subject instructor's responses to LKPD got an average score of 4.67 with the "Practical" criteria, while student comments got an average score of 4.30 with the "Interesting" category. The results of the LKPD test show that the average student score is 76.41, exceeding the KKM, which is 70, and the student's completeness achievement is 82.35% in the "Effective" category. As a result, the teaching materials are in the form of Connecting, Organizing, Reflecting and Expanding (INTI)-based worksheets to facilitate the ability to solve mathematical problems on solid material (triangles and rectangles), so that they are declared valid, useful and interesting.
