AbstractThe purpose of this study was to describe the validity of learning tools in fostering students' motivation, self-efficacy and mathematics learning outcomes through jigsaw cooperative learning. Learning tools consist of syllabus, lesson plans, student activity sheet, learning motivation questionnaire, self-efficacy questionnaire and learning outcomes tests which include pretest and posttest. This type of research is descriptive. The research instrument is a learning device validation sheet. The research subject is a learning device. The object of research is the level of validity of the learning device. The results showed that the validated learning tools obtained a validity index in the valid category where the syllabus was 0.78, lesson plan was 0.80, student activity sheet was 0.79, Learning Motivation Questionnaire was 0.85, Learning self-efficacy questionnaire was 0.84. , test (Pre-test) learning outcomes of 0.80, test (post-test) Learning Outcomes of 0.84, the total average value of learning devices is 0.81. Based on the results of the study, it was concluded that the Jigsaw type cooperative learning tool in fostering motivation, self-efficacy and student learning outcomes was valid.
