Validity and Practicality of Flipped Classroom Based on Structured Inquiry Using LMS Moodle on the Material of Chemical Equilibrium for Phase F High School

Chemical equilibrium is one of the abstract materials with concrete examples. This material is considered difficult by students. This study aims to determine the validity and practicality of a structured inquiry-based flipped classroom learning system using LMS Moodle on chemical equilibrium material high school phase F. The type of research is EDR (Education Design Research) research with the Plomp development model. The flipped classroom learning system was validated by three chemistry lecturers FMIPA UNP and two chemistry teachers in SMA Negeri 12 Padang obtained the average Aiken's V of 0.87 with valid category. Practicality conducted by two chemistry teachers in SMA Negeri 12 Padang obtained an average result of 94% with a convenient category. Practicality conducted by nine students of SMA Negeri 12 Padang obtained an average result of 94% with a convenient category. The results showed that the structured inquiry-based flipped classroom learning system using LMS Moodle on high school phase F chemical equilibrium material proved to be valid and practical
