In order to investigate how attitudes among preservice teachers are influenced by participation in a computer literacy course and to test the utility of an attitude questionnaire, a study was conducted with 75 college preservice teachers (56 females and 19 males). The course was developed to teach the use and understanding of computer technologies in an educational setting. Seventy-three students completed the Computer Literacy Attitude Survey, developed for this study, at the beginning of the course, and 65 completed it at the end of the course. Participation in the course appeared to improve student attitudes toward computers and their use. After completing the course, students had less anxiety and more confidence, and they generally valued computers more. Students also evaluated the course favorably, commenting on its clarity and utility. Three tables present study findings. (Contains 26 references.) (SLD)
