This study explored the levels of anxiety over computer use of high school students based on sex, grade level, and prior computer experience. Subjects were 67 high school students, 38 males and 29 females. The instrument used was a computer anxiety subscale of 10 items from an instrument designed by Loyd and Gressard (1984). The items presented positively and negatively worded statements about reactions to computer use, and students were asked to respond using a four-category scale ranging from strongly agree to strongly disagree. The data showed that both gender and computer experience, but not grade level, produced a significant difference in computer anxiety. Male students had higher mean scores, indicating less anxiety, than female students, and students with more computer experience received higher mean scores than students who had less computer experience.
