This research paper describes an investigation into the impacts of a flipped pedagogy on student-perceived classroom climate. Flipped classrooms have gained considerable attention lately. It has been shown that delivering technical content via online modules frees up class time for active learning and increases both peer interaction and student-faculty interaction. Here we ask the question: Does the flipped model also increase the supportive nature of the learning environment. Classroom climate, as well as self-efficacy and value, have been shown to improve students motivation for learning. We used the College and University Classroom Environment Inventory (CUCEI) to assess the classroom climate in both the flipped class and various control classes that were not flipped. This inventory includes seven psychosocial dimensions of classroom climate: personalization, involvement, student cohesiveness, satisfaction, task orientation, innovation, and individualization. Our specific research questions were: 1. Do students perceive a more positive classroom climate in a flipped classroom vs. a traditional lecture-based course when controlled for course content and instructor? 2. What psychosocial dimensions were most impacted by the flipped pedagogy? One group of students (Group “A”) had just completed the flipped course. The second group (Group “B”) consisted of students who had just completed the same course, but taught in a traditional format. This was to control for the effect of the course material on students’ motivation and interest. The third group (Group “C”) consisted of students who had just completed a different engineering course taught by the same instructor in a traditional format. This was to control for a different instructor. The groups were analyzed using a one-way ANOVA. The responses were analyzed based on each of the seven subscales within the CUCEI, as well as on an overall score combining all seven subscales. Our results show significant difference between the three groups based on overall score ...
