Bringing about positive teacher change in physical education is often a slow process not supported by traditional professional development practices. The purpose of this study was (a) to assess the usage and satisfaction with the online site PE Central and (b) to ascertain whether PE Central constitutes a valid source of professional development leading to changes in teaching practices and student learning outcomes. Participants (45 pre-service and 288 in-service teachers) completed an online survey assessing the effects of using PE Central on their perceptions of usage, satisfaction, professional development, teacher change, and student engagement. Results indicated no significant differences between pre- and in-service teachers in usage and satisfaction of PE Central, but that on average the sample population uses it monthly and are more satisfied than not with the site. Results further indicated that PE Central is positively related to provisional and permanent teacher change and increased student engagement. However, the researcher recommends changes in order for the site to become a viable professional development option for teachers.
