UNPLAG STEM Approach: The Development of Optical Instruments Module to Foster Scientific Literacy Skill

STEM is an approach that seemly considered helpful in online learning because it can facilitate students to learn about 21st-century skills. This study aimed to develop module-based STEM in improving scientific literacy skills in distance learning through e-learning. Because this research developed module-based STEM, this study was named developmental research. The research procedure follows the stages of the R & D method developed by Barg and Gall, including preliminary, product planning, development, validation (validation by experts), revision, and field testing. Modules that have been declared valid by experts are field-tested using one group pretest-posttest design in an experimental class. The results show that the feasibility of module-based STEM in the distance learning model to increase students' skills within scientific literacy was valid with an average score of 4.28 by two experts. In addition, the application of integrated STEM teaching materials through e-learning has a moderate effect on students' scientific literacy skills since the N-gain score was 0.
