Development of Learning Materials Based on Guided Inquiry to Train Scientific Literacy in Primary School

This research is development of science learning materials based on guided inquiry. It modified 4D models on Human Digestive System material to train students' literacy. It used One Group Pretest-Posttest Design. The result showed that learning device consisting of learning plan, student activity sheet, and test scientific literacy deserves to be applied based on three criteria of expedience. First, valid assessment by experts reached average score 5. Second, the practical enforceability was 95.83% done, the result of scientific literacy ability was 94%, students' response was positive, and students' activities indicate ongoing activities. The students' learning outcomes increased on pretest and posttest in high category based on N gain analysis, i.e. 0.83. The research concluded that material was valid, practical, and effective in increasing students' scientific literacy ability.
