The document summarizes research on measuring students' sense of community in blended learning courses using the Classroom Community Scale (CCS). The study administered the CCS survey and interviews to students in blended English courses at three Japanese universities. Results showed the CCS is a valid way to measure student satisfaction and perceived learning. Female students and those with more online interaction reported higher CCS scores. While instructors' perceptions of community did not always match students' CCS responses, the scale provides a way to evaluate online learning experiences across contexts.
