The Development of Learning Device of Lesson Study for Learning Community Using Google Classroom and Quizizz Media and Their Effect on Students' Creative Thinking Skills

Abstract

Google classroom and quizizz are ways to optimize learning in virtual classes in the online era. The process and results of developing LSLC-based mathematics learning device using google classroom and quizizz media and their effect on students' creative thinking skills on the material for the system of linear equations with three-variables in class X of Mathematics and Natural Sciences. The method used in this research was a combination research method or a mixed method between development research (research and development) using 4-D models (four-D models) and experimental research. Results of LSLC-based learning device using google classroom and quizizz media In improving students' creative thinking skills, they met the criteria for the quality and feasibility of developing learning device that have been determined, namely meeting the criteria for validity, effectiveness and practicality. The validity of the lesson plans, worksheets and learning outcomes tests were categorized as very valid and the learning outcomes tests were tested for validity and reliability statistically and showed valid and reliable data. Practicality met the good criteria. The effectiveness was in good criteria, for the completeness analysis, there were 86% of students completed the development class and the results of student response questionnaires which reached 84% of students who gave positive responses. Creative thinking skills of students who were taught using LSLC-based learning device using google classroom and quizizz media were better when compared to the creative thinking skills of students who were taught using google classroom and quizizz media
