Two studies were conducted of students in grades 1-12 in Washington state to determine how children at various grade levels perceived males' and females' interest in using computers. A 46-item instrument was field tested using 124 students from three small school districts whose administrators had volunteered to participate. Four sections of an undergraduate educational psychology class also responded to the questionnaire. The interest questionnaire was then administered to 375 students in grades 1, 3, 5, 7, 9, and 11. Results indicated that, although children in the lower grades perceived computers as of interest to both sexes, this pattern underwent a reversal among seventh and ninth grade subjects. To follow up this observation, a second study was done and a revised instrument was administered to a minimum of two classrooms each in grades 1, 3, 5, 7, 9, and 11 in a medium-sized school district. Those results indicated that first graders rated interest in computers significantly higher than students at all other grade levels, and the majority of both boys and girls see boys as having a higher degree of computer interest than girls. Data tables and graphs illustrate the findings. (JB)
