In this study, the effects of presentation graphics on Preservice Science Teachers' (PST) attitudes towards physics were investigated. The research was performed on two groups. While one group was an experimental group, another was a control group. The research was conducted in the context of an undergraduate-level physics course, and this course was taught to two groups. While the experimental group consisted of forty PST and was taught with presentation graphics as well as traditional lecturing method, the control group consisted of forty PST and was only taught with traditional lecturing method. The data were collected by means of a scale of attitudes towards physics. In light of the findings of the present research, it was concluded that the attitudes of the experimental group towards physics were much more improved positively than the control groups' attitude toward physics after the treatment involving presentation graphics.
