ABSTRACT
Development of the STEM science module for light materials and optical instruments for class VIII SMPN 2 Kalianget. This study has the aim of determining the validity of independent teaching materials, namely the STEM Science module, (2) obtaining teacher responses and student responses. The subjects used class VIII SMPN 2 Kalianget students. This research refers to research and development of 4-D (four D). The validity data used Content Validity Index (CVI) analysis. Respondent data from the elements of teachers and students using questionnaire analysis. The results showed that the validity of the STEM science module on light material and optical instruments for class VIII was declared valid, as indicated by a CVI score of 1.00 (appropriate validity) in terms of material, language and media aspects. The results of teacher and student responses are in the positive category. The teacher's response is 100%, while the student's response is 98.48% with the "achieved" category.
