This study aimed at investigate the effect of vlogging on EFL student teachers' teaching self-efficacy. A pretest-posttest control group design was adopted, consisting of a control group and an experimental group, each consisting of 12 4th-year EFL student teachers at Faculty of Education, Suez University. A teaching self-efficacy scale was prepared and administered to both groups before the experiment. Participants in the experimental group were trained in vlogging and created a group vlog. For a whole term, they videotaped themselves during Teaching Practice and uploaded the videos to the vlog. They reflected on their teaching performance in the video clips and commented on each others' performance as well. The teaching self-efficacy scale was administered to both groups after the experiment. Statistical analysis revealed a significant improvement in teaching self-efficacy between pretest and posttest for the experimental group while the control group showed no significant improvement. It was recommended that vlogs be used as a method for enhancing EFL teaching self-efficacy.
