Abstract
This study aims to: (1) produce appropriate POE-based LKPD to improve learning activities and critical thinking skills of students at SMPN 38 Medan; (2) knowing the magnitude of the increase in student learning activities using POE-based LKPD; and (3) This study aims to determine the increase in students' critical thinking skills by using POE-based worksheets. This research is a research based on development (R&D) with a 4D Model design consisting of four stages, namely Define, Design, Develop, and Disseminate.The results showed that: (1) POE-based LKPD had been produced with a very good category and suitable to be used to improve learning activities and critical thinking skills of high school students; (2) the increase in students' learning activities using POE-based LKPD is indicated by the standard gain value of 0.726 in the high category; and (3) From the results of this study there was an increase in students' critical thinking skills using POE-based worksheets indicated by a standard gain value of 0.445 in the medium category.
