Abstract: A meta-analytical study of empirical research on gender-based differences in Information and Communication Technology (ICT) perception and use for educational purposes is based on data from 363 primary studies and encompasses four major outcome categories: (1) ICT general attitudes and satisfaction; (2) ICT confidence; (3) ICT interest and motivation; and (4) actual use of ICT tools and applications. The respective weighted average effect sizes (random effects model) were: (1) g+=0.066 (k=153, N=77,977); (2) g+=0.228 (k=163, N=65,501); (3) g+=0.079 (k=121, N=65,501); and (4) g+=0.048 (k=117, N=74,743), all in favour of male students, though the usage effect was not statistically significant. The follow-up moderator variable analyses explored systematic variations in effect sizes and described patterns of results within and across outcome categories.
