sets based science teaching materials with guided inquiry learning model to improve learning outcomes in optical geometry materials

this study aims to analyze the effectiveness of sets based science teaching materials with guided inquiry learning model to improve the students cognitive learning outcomes. this research was conducted by using learning cycles. the teaching materials developed were tested in class viii mts bilingual muslimat nu pucang sidoarjo semester even 2018/2019 academic year with the design of one group pretest-posttest design. teaching materials developed include: (a) syllabus (b) lesson plan, (c) student books, (d) worksheet, and (e) learning outcomes assessment sheet. the research parameters measured were the effectiveness of learning materials. the research data was obtained through validation, observation and test methods. the results of the study were analyzed descriptively quantitatively and qualitatively. science literacy abilities of students are analyzed by n-gain. the results showed that (a) the learning devices developed were categorized as very valid, (b) the learning activities were carried out very well, (c) moderate scientific literacy skills. based on the results of the analysis and discussion, it was concluded that the science learning device guided inquiry model that was developed valid, practical, and effective was used to increasing students cognitive learning outcomes.
