The effects of math anxiety and sex on computer anxiety, computer confidence, and computer liking were investigated with 161 junior high and high school language arts students; 119 community college mathematics students; and 76 college students residing in dormitories. The Computer Attitude Scale (Loyd and Gressard, 1984) was used to measure attitudes toward learning about and using computers. Each of its three subscales consists of 10 items and presents positively and negatively worded statements such as, "Computers do not scare me at all," with a four-point response scale. Math anxiety was measured with a modified version of the Mathematics Anxiety Scale (Fennema and Sherman, 1976). Results indicate that, after controlling for experience, math anxiety explained a significant addition of variance for computer anxiety, computer confidence, and computer liking. Sex differences were not significant. These findings suggest that schools may need to decentralize their computer activities in order to help counter the association of computers with mathematics; studies of math anxiety may provide insight into computer anxiety; and successful math anxiety treatments may also help to relieve computer anxiety. Six references and six tables are included. (Author/LMM)
