Compares the impact of two different computer-mediated communication (CMC) systems, with different prescribed guidelines for use, on the per-person volume of online interchanges in two graduate classes. Hypothesies a relationship between system characteristics, guidelines for use, and the perpetuation of verbal interaction in settings where CMC is…

Tests the hypothesis that two general developmentally-based levels of hypothesis-testing skills exist.
