Electronic mail (e-mail) is an extremely important medium for Internet-based education. Due to its unique characteristics, there is reason to be concerned that students do not put appropriate care into writing messages that are sent via e-mail. This has significant implications for the effectiveness of online learning environments. This paper describes an empirical research project to investigate the amount of thought students put into e-mail communication versus traditional face-to-face communication. A survey was administered to 596 undergraduates. The results of this survey indicate that students put significantly more thought into e-mail communication with the instructor and groups of peers than they do for equivalent face-to-face communication. At the same time, students tend to put about the same amount of thought into e-mail compared to verbal communication with individual peers. Finally, the research uncovered some interesting patterns concerning student gender and technology comfort as predictors of thought put into e-mail communication. (Contains 1 table and 3 figures.)
