This study investigated the relationship between English language teachers' motives to use online teaching resources and three types of Internet practices: teachers' practices in using the Internet to collaborate with others, teachers' practices for classroom teaching, and the Internet's contribution to the overall professional development of teachers. Gender was also used to assess differences in the proposed model. In this study, one hundred and seventy-four English language teachers completed an online survey. SmartPLS was used to assess the measurement and the structural models. The results indicated that participation was a significant determinant of both English language teachers' Internet-related practices at classroom level and the Internet's contribution to the overall professional development. Considering gender differences, the results demonstrated that participation in online professional development was significantly related to the English language teachers' practices at classroom level for males but not for females.
