Abstract
The aim of this research is to develop teaching materials (lesson plan and student worksheet) based on Engineering Design Process through PjBL-STEM to improve students^ scientific literacy that is valid, effective and practical. The type of research used is R&D with the ADDIE model. The validation sheet of teaching materials, scientific literacy test, and response questionnaire to the implementation of learning were used as instruments in this study. The subjects in this research were 33 tenth-grade students of MAN 3 Banda Aceh. The results showed that the validity of the teaching materials developed obtained a score of 3.5 and was in the valid category, The effectiveness of improving scientific literacy skills analyzed using the N-Gain test obtained a score of 0.736 with a high category, and practicality was in the very practical category. Based on these results, it can be concluded that the teaching materials developed are feasible to use to improve students^ scientific literacy skills.
