This cross-sectional study examines students' and faculty members' perceptions on their use of active learning classrooms in a university in Singapore. The study targets students (398) and faculty (6) who use active learning classrooms -- Applied and Collaborative learning Environment (ACE) rooms. It investigated whether novelty to the learning environment plays a part in the perceptions and experiences of the rooms, through the Active Learning Classroom (ALC) Survey. Results reveal that effective utilisation, room/course fit, student- centred activities in the ACE room all play major roles in increasing student engagement and learning; yet no difference in the first-time or repeated student-users' experience.
