Evaluation of the physical classroom by students and professors: a lens model approach

A method for linking classroom evaluations to specific physical properties and for comparing the evaluations of different groups is described and illustrated. Thirty-five college classrooms were photographed and shown to 20 professors and 51 undergraduate students, each of whom evaluated the friendliness of and their overall preference for all the classrooms. Seven physical properties of the classrooms were reliably assessed by independent observers. Using a modified Brunswik lens model, the relations between the physical properties and the evaluations by the two groups were established and compared. Between 40 and 57 per cent of the variance in the evaluations could be explained from only three classroom properties: view to outdoors, seating comfort and seating arrangement. Evaluations by the students and professors were surprisingly similar, an encouraging sign for classroom designers.     

Replication and Pedagogy in the History of Psychology VI: Egon Brunswik on Perception and Explicit Reasoning

Egon Brunswik (1903–1955) first made an interesting distinction between perception and explicit reasoning, arguing that perception included quick estimates of an object’s size, nearly always resulting in good approximations in uncertain environments, whereas explicit reasoning, while better at achieving exact estimates, could often fail by wide margins. An experiment conducted by Brunswik to investigate these ideas was never published and the only available information is a figure of the results presented in a posthumous book in 1956. We replicated and extended his study to gain insight into the procedures Brunswik used in obtaining his results. Explicit reasoning resulted in fewer errors, yet more extreme ones than perception. Brunswik’s graphical analysis of the results led to different conclusions, however, than did a modern statistically-based analysis.
