Abundant research supports the benefits of the flipped classroom approach on learning outcomes. Yet how students evaluate the flipped learning environment remains largely unknown. The present study aims to investigate 1) the students' perceptions of their flipped learning and 2) whether disciplinary differences can be observed in students' perceptions. Drawing upon the theoretical framework outlined in Brame (2013), our findings illustrated that students (N = 407) from different disciplines do vary their evaluation of the flipped learning environment. Those whose academic disciplines related to the application of knowledge evaluated the four components -- exposure, incentive, assessment, and activities -- more positively than those whose academic disciplines focus more on theoretical exploration. It is noteworthy that how subject knowledge is developed does not influence perception of the flipped learning environment. Such findings can supplement the traditional outcome-based approach of flipped classroom research by understanding the learning environment. All in all, the findings can point to practical and theoretical implications for designing a flipped classroom environment, highlighting the needs in designing the learning environment.
