Pengembangan LKPD Berbasis Project Based Leraning Terintegrasi STEM Untuk Meningkatkan Keterampilan Berpikir Kritis Siswa SMP

Abstract

Critical thinking skills are one of the essential 21st-century skills that students need to have. However, students' critical thinking skills in Indonesia are still relatively low, one of which is caused by the limited teaching materials that can facilitate the development of these skills. This study aims to develop teaching materials in the form of Student Worksheets (LKPD) based on Project Based Learning integrated with STEM to improve students' critical thinking skills, as well as to determine the level of validity, practicality, and effectiveness of the developed teaching materials. The type of research used is Research and Development (R&D) with the ADDIE development model, which includes the stages of analyze, design, develop, implement, and evaluate. The results show that the LKPD based on Project Based Learning integrated with STEM obtained a validity value with an average percentage of 90% and is included in the very valid category. The level of practicality of the LKPD based on the results of observations of learning implementation obtained a percentage of 89% with a very practical category. The effectiveness of LKPD is shown by the increase in students' critical thinking skills with an N-gain value of 0.59 in the moderate category, and is supported by the results of the student response questionnaire which obtained a percentage of 83.7% in the very good category. So it can be concluded that the LKPD based on Project Based Learning integrated with STEM that has been developed is declared valid, practical, and effective for use as teaching materials in science learning.
