PENGEMBANGAN LKPD BERBASIS KEMAMPUAN PEMECAHAN MASALAH PADA MATERI PECAHAN MI/SD

Abstract

This research was carried out to develop LKPD products based on problem-solving abilities on MI/SD fractional materials. The LKPD products produced aim to find out their feasibility through feasibility tests, practicality and effectiveness as well as a learning medium to help improve problem-solving skills in students' fractional materials. The researcher uses a research and development (R&D) method with a 4D model consisting of four stages, namely the definition stage, the design stage, the development stage, and the deployment stage. The subject of this research is the LKPD product to be developed, two validators consisting of material experts and design experts, a teacher as a responder and 40 students of class V MIN 7 Medan City. The research instruments used include expert validation sheets, interviews with subject teachers, teacher response questionnaires and student certificates and tests. The research instruments used include expert validation sheets, interviews with subject teachers, teacher response questionnaires and student certificates and tests. The results of the feasibility test obtained a score of 80% for material experts, and design experts obtained a score of 92%. The average score of the two experts was 86% with a very decent category. The results of the practicality test by teachers were 97.3% and students were 98.5% in the very practical category. The results of the student test trial obtained an average score of 30.46 for the pretest, an average score of 85.78.The N-Gain obtained was 0.79, meaning that the N-Gain > 0.7 with the effective category.
