The questionnaire has three parts, which consists of demographic items, level of computer use items, and Attitude toward Computer Supported Teaching items. The data gathered were analyzed by SPSS 14 software. Cronbach’s Alpha value was 0.93. Mean, standard deviation, and Pearson correlation analyses were used. Results indicated that science teachers’ level of computer use was high and their attitudes toward CST were positive. There was a moderate positive correlation between teachers’ computer use level and their attitudes toward CST. Findings were discussed in the framework of the related literature, and some suggestions were made.
