Abstract

This quantitative study aims to analyze the effectiveness of STEM-integrated Project-Based Learning (PjBL) E-Worksheets on the cognitive learning outcomes of fifth-grade students at SD Negeri 76 Bengkulu City. The research is driven by the dominance of conventional teaching methods and low technology integration, resulting in students^ failure to meet minimum mastery criteria. Using the Research and Development (R&D) method with the ADDIE model, this study specifically focuses on the Evaluation phase to measure the media^s impact. A One-Group Pretest-Posttest experimental design was employed, with data collected through cognitive tests on the perimeter of squares and rectangles and analyzed using the N-Gain formula. The results in the evaluation stage demonstrate that the STEM-PjBL E-Worksheet is highly effective in improving cognitive achievement, evidenced by an N-Gain score of 0.72, categorized as ^High.^ The integration of science, technology, engineering, and mathematics through a photo frame project successfully concretizes abstract concepts for students. In conclusion, the STEM-PjBL E-Worksheet is an effective and feasible innovative tool to support the implementation of the Merdeka Curriculum in elementary schools.
