“…Typically, the structure of the relevance ratings has not been of interest. One notable exception is in the work of Greenwood et al (1974) who factor analyzed both faculty and student ratings of item relevance. While in the present study, oblique rotation was performed on a pooled within-group correlation matrix among lecture/discussion items, in the Greenwood et al study, orthogonal rotation was performed on a total group correlation matrix among items designed to cover a broad spectrum of course settings.…”
