The purpose of this study was to investigate the effect of integrating blogging into the English as a Foreign Language (EFL) curriculum on students' performance in expressive writing. Previous studies have shown that integrating blogging into EFL learning raises students' motivation and develops their linguistic and social skills as a result of the interaction between the blogger and his/her readers. In the present study, 22 high school Israeli-Arab students were asked to post guided essays to personal blogs and comment on each other's posts. The blogs were analyzed and the students' errors categorized, counted, and recorded over a four-month period. In addition, the students filled out a questionnaire at the end of the study period aimed at understanding their attitudes towards the process and the blogging experience. The results of the study showed a significant improvement in writing quality and a decrease in the amount of student errors. Moreover, the students expressed a positive attitude towards using blogs as a platform for developing writing skills. [For the complete volume, see ED578177.]
