PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) MATEMATIKA BERBASIS MASALAH

This research aims to develop problem-based Mathematics Worksheets for Class V Elementary School Fractions Material. The development of problem-based Mathematics LKPD is needed to apply a problem-solving-based learning model that can improve students' ability to solve non-routine math problems. Research and development (R&D) have applied in this research which Research and Development consists of 4 main stages, namely 1) Exploring potentials and problems in using LKPD; (2) Conducting literature studies and collecting information to develop problem-solving-based worksheets; (3) Developing  designs of LKPD with problem-based; (4) Validating experts and practitioners regarding problem-based LKPD designs; (5) LKPD design based on tested problems. Determination of research objects selected by purposive sampling. The object of research is the fifth grades teacher at SD Negeri 100 Kendari. Data collection techniques using observation sheets and validation sheets. The data analysis technique in this research used a qualitative descriptive analysis technique. Based on the results of the research and discussion, it can be concluded that the development of Problem-Based Mathematics Worksheets in SD Negeri 100 Kendari is appropriate for use in teaching and learning. This is based on the validation results of design experts of 3.73 including the appropriate category, the validation results of material experts of 3.87 including the feasible category and practitioner validation by teachers of 3.93 including the feasible category
