Methodological issues are illuminated by reference to analyses of environment data. Analyses include clustering techniques applied at the item level instead of the conventional scale level. Clusters derived using different units of analysis (namely, between and pooled within) are compared and contrasted. (RL)

An analytical, integrating perspective on much of the classroom environment research conducted in the 1970s is provided. The initial development of the Learning Environment Inventory and original research programs are described. (RL)

Course difficulty, interpersonal tension, and course speed were related to negative attitudes. (CP)
