Development of stem-based lkpd on the theme of my house's electric circuits to improve explanation, inference and evaluation skills

One comprehensive and integrative learning approach is the STEM approach. This approach can improve students' explanatory, inference, and evaluation skills by combining the four disciplines: science, technology, engineering, and mathematics. Implementing STEM in teaching and learning activities can use teaching materials, including LKPD. This study aims to produce a valid, practical, and effective STEM-based LKPD product to improve students' explanatory, inference, and evaluation skills. The method used in this study is the research and development method. A validity test has been carried out consisting of a product validity test that is declared valid and suitable for use with a percentage of 80.9%. The effectiveness test is carried out with n-gain and effect size tests. Each obtained a result of 0.68 with the medium category and 2.7 with the high category. Practicality tests conducted by teachers obtained an average result of 83% and students of 87%. So, STEM-based LKPD can effectively improve students' explanatory, inference, and evaluation skills.
