The aim of this study was to examine the predictors of pre-service teachers' use of Web 2.0 tools during a teaching internship, after a course that emphasized the use of the tools for instructional activities. Results revealed that integrating Web 2.0 tools during their teaching internship was strongly predicted by participants' perceived enjoyment in using the tools in the communication technology course. The results of this study indicate the importance of active engagement and enjoyment in the integration and implementation of Web 2.0 technologies in teaching environments by pre-service teachers. As the comfort level and enjoyment increases by virtue of the employment of Web 2.0 tools by the pre-service teachers, teacher educators can expect from their students increased motivation, effectiveness, and competence in integrating technology into their curriculum.
