In recent years, organisations and institutions of higher learning have adopted group/team structures to facilitate learning and goal completion. A number of methods have been used to better understand and facilitate group learning. In this paper, I explore one such method: collaborative critical thinking, heretofore, a relatively unknown construct. Considering the nascent nature of this construct, the primary goal of this research is to conceptualize and define collaborative critical thinking using the known constructs cooperative and collaborative learning, and critical thinking. As part of this process, cooperative and collaborative learning will be differentiated, and directions for future research proposed. (Contains 1 table and 1 footnote.)
