Polymer is topic of chemistry which full of the concept and the application polymer is often found in everyday life. But based on the results of a survey with Chemistry teachers from different provinces, student’s mastery of concepts polymer is low level of concept mastery. Most of the teachers ignored the development student’s mastery of concepts polymer. This study aims to obtain a polymer learning design using the RADEC model based on google classroom to develop student’s mastery of concepts. The researcher used the Greivemeijer & Cobb Design-Based Research (DBR) research method consisting of 3 stages: Preliminary Design, Design Experiment and Retrospective Analysis. Participants in this study were senior high school students, Chemistry teachers and 3 observers who understood the RADEC model. Data collected by interviewing, testing (pre-teaching questions) and observing the activities of teachers and students. The results of the study indicate that the learning design developed by the researcher is valid, accessible and teachable. This is indicated by the results of expert validation and RADEC based on google classroom can develop student’s mastery of concepts.
