(from Carnegie Mellon University Eberly Center). Classroom Climate: Creating a Supportive Classroom Environment. Why is classroom climate Important? The teaching-learning process is an inherently social act, and as instructors we need to be mindful of the quality of the social and emotional dynamics in our course, because they impact learning and performance. In fact, a well-established body of research has documented the effects of a “chilly classroom climate” on some students or groups of students, in particular women and other minorities (Hall, 1982). For example, climate regulates the circulation and construction of knowledge and engenders emotions that impact learning, among other areas.
