The purpose of the study is to investigate the changes in computer anxiety, attitudes towards computers, and feelings related to computers among students due to participation in the basic course of computer science. The theoretical background is based on theories of human-computer interaction, test anxiety, and resistance to change. The subjects were 29 education majors in the basic computer science course. They answered a three-part questionnaire both at the beginning and at the end of the course. The main result of the study indicated that the basic course in computer science reduced anxiety. The experience with computer equipment and the use of computers reduced anxiety most of all. The course also had positive effects on the following attitudes toward new technology: the impression of human-computer interaction and the impression of computers in the future. At the end of the course the students' estimation of their own knowledge was much higher that at the beginning of the course. The course also had a strong effect on negative feelings in that it reduced the fear of failure and the desire to escape. (Contains 9 references.) (Author/ALF)
