Validity of teaching materials for environmentally friendly technology products using STEM-based guided inquiry to improve students’ scientific literacy competence

Abstract

Students’ scientific literacy skills need to be improved because students in the 5.0 society era must have various skills. The availability of relevant student books has limitations in presenting the material. In overcoming this problem, science teaching materials that contain the scientific literacy referred to the 21st-century situation are needed. Therefore, research was conducted on developing integrated science teaching materials with STEM-based Guided Inquiry (STEM-based GI) to improve students’ scientific literacy competence. This study aims to determine the validity of teaching materials (integrated science modules, lesson plans, and learning outcomes tests) for STEM-based GI on the topic of Environmentally Friendly Technology (EFT) products to improve students’ scientific literacy competence. The research and development procedure used was the formative evaluation model. This research procedure was divided into three stages: self-evaluation, prototyping, and evaluation of field tests. However, this research only reached the stage of expert validation (prototyping). The results showed that the average value of the three validators was 94.33% which was included in the very valid category. The coefficient of agreement between validators was (R) 87.10%, included in the high category. Therefore, the resulting teaching material was valid and improved scientific literacy in junior high school science learning.
