PENGEMBANGAN LKPD BERBASIS PROBLEM BASED LEARNING TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIS PESERTA DIDIK KELAS VII SMP PADA MATERI PERBANDINGAN

Karmelia Yuanda - Universitas Negeri Padang )

Abstract


This research is development research which aims to produce the LKPD based on problem-based learning that are valid, practical and effective in comparative material for class VII SMP. It is Plomp's development model that is utilised. This process consists of three steps: research, prototype, and testing. The data for this study was gathered from both students and teachers through questionnaires, practice and observation charts, test scores, and validity and reliability statements. These tools were used to evaluate the ability to solve mathematical problems. With a total validity score of 87.50%, the validation results demonstrated that the LKPD created was deemed quite valid. With a particularly practical category, the LKPD's practicality experiment obtained an impressive success percentage of 93.50%. The mathematical problem-solving ability exam is considered to be of extremely high quality, with a completeness rating of 83.33%. With LKPD's valid and practical problem-based learning approach, students' problem-solving skills in mathematics have been enhanced.

Keywords: LKPD,  Problem Based Learning, Mathematics Problem Solving ability
