The goal of this study was to find out if the difference between boys and girls in computer literacy can be leveled out in a laptop program where each student has his/her own mobile computer to work with at home and at school. Ninth grade students (n=113) from laptop and non-laptop classes in a German high school were tested for their computer knowledge and computer confidence. A computer literacy test was developed that included the following scales: (1) confidence in using computers; (2) confidence in using the Internet; (3) computers as a tool or toy; (4) knowledge in hardware and operating system; (5) knowledge in common office applications and presentation software; (6) knowledge in using the World Wide Web for search tasks and in using e-mail; and (7) knowledge in basic security issues. Students from laptop classes outperformed students from non-laptop classes in computer knowledge, while there was no difference in computer confidence. In comparison to the non-laptop classes, the gender gap in computer knowledge was much smaller in the laptop classes. In computer confidence, no harmonizing effect of the laptops was found.
