A study surveyed 972 college students for their preferences in classroom arrangement (tradition straight-row, horseshoe, and modular) and their seating preferences within each style. Results indicated that students' arrangement preferences are influenced by both attractiveness of the course and the individual student's communication apprehension level. The conclusion developed from the data is that manipulation of either the type or the amount of communication in a classroom may be more difficult than previously believed, since such manipulation could hinder learning by engendering negative affective behavior in students.
