D. P. Thompson (1987) pointed out that the e-mail network can help students work collaboratively, solve problems, and experience writing as communication in the real situation. This study examined the impact of e-mail debate on intercultural sensitivity, writing apprehension, and computer anxiety. Fifty-four students in two sections of a junior-level intercultural communication class participated in the 12-week project. Divided into groups, they were required to participate in debates (following the rules of debate) that included the following assertions: (1) intercultural marriage is acceptable; (2) intercultural communication should be part of any college curriculum; (3) people from different cultures cause problems in the United States. Several measurement tests were given. The 22-item Intercultural Communication Attitudes Scale (1993) was used to test participants' intercultural sensitivity. The 26-item Daly-Miller Test (1975) was used for the measurement of writing apprehension. The 20-item Computer Anxiety Scale (1990) was used to measure the degree of participants' computer anxiety. Results showed significant changes between pretest and posttest in intercultural sensitivity and computer anxiety, but no significant changes in writing apprehension.
