This study examined whether there was a difference in the attitudes toward computer use of preservice and inservice teachers. The Computer Literacy Attitude Survey, a survey which reflected attitudes toward computer use, was administered to 50 preservice teachers enrolled in a 10-week instructional technology course and 30 inservice teachers enrolled in two 10-week instructional technology courses. The courses were systematically planned to teach the use and understanding of computer technologies in an educational setting. The courses included background information about computers and hands-on experience. Participants completed the Computer Literacy Attitude Survey before the course began and again at the end of the course to determine whether a systematically designed computer course might influence their attitudes. Data analysis indicated that the course did influence the attitudes of preservice and inservice teachers. There were differences in the attitudes of the preservice and inservice teachers as they entered the classes. Preservice teachers were influenced more positively than were inservice teachers.
