Le résumé fourni par la source

Abstract This study was conducted to produce teaching materials (lesson plans and student worksheets) based on the Engineering Design Process through PjBL-STEM to improve students’ scientific literacy in a valid, effective, and practical manner. The type of research used was R&D with the ADDIE model. Teaching materials validation sheets, scientific literacy tests, and questionnaires on learning implementation were used as research instruments. Thirty-three students in grade X at MAN 3 Banda Aceh were involved in the implementation of the teaching materials. The research findings show that the validity of the teaching materials is very valid, with an overall average score of 88.40. The increase in scientific literacy skills shows a high category, as evidenced by the N-Gain score of 0.736, and the practicality is in the very practical category. Based on these findings, it is confirmed that the teaching materials produced have a high level of validity, effectiveness, and practicality in supporting the improvement of students’ scientific literacy.
