PENGEMBANGAN LKPD (LEMBAR KERJA PESERTA DIDIK) BERBASIS STEM UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KREATIF PADA MATERI SISTEM EKSKRESI MANUSIA DI SMP

Abstract

This study aims to determine the feasibility level of the STEM-based LKPD to improve students' creative thinking skills on the human excretory system material, to find out the students' responses to the STEM-based LKPD to improve students' creative thinking skills on the human excretory system material, and to know the effectiveness of STEM-based worksheets to improve students' creative thinking skills on the material of the human excretory system. This type of research is development research (R&D) with the ADDIE model. Product trials include small group trials with a sample of 10 people and large group trials consisting of 30 students. The instrument used in this study was a validation sheet by material, learning, and design experts, as well as a test in the form of a description of 10 questions to measure creative thinking skills on the material of the human excretory system. The results of this study indicate that the developed worksheets are very feasible to use to improve students' creative thinking skills based on the assessments of two material experts, two learning experts, and two design experts with consecutive average scores: 91.1%, 91.54%, and 90.62% with very decent criteria. The developed LKPD also received a decent response from students with the results obtained in small groups with an average of 81.6% and large groups of 96.5% and effective for improving students' creative thinking skills, with average results pretest is 44.33 and the average posttest result is 84.25 with an average N-Gain of 0.71 with a high interpretation.
