A possible explanation for students' perception of improvement, whether real or imagined, especially in fluency, is that the blog's speaking environment, where freedom and safety were paramount, encourage students to take risks with the target language and to emphasize content over form, which resulted in a sense of improved fluency. In addition, the task-based nature of blogging promotes authentic and purposeful language use, with the form playing a secondary role (Skehan, 1996; Willis & Willis, 2001). This also aids students' fluency development.
In the current study, some participants recorded their blogs all at once rather than spacing them out evenly throughout the semester. One consequence of a last-minute rush could be a significant diminution of the quality and quantity of the blogs. Students would either make shorter entries near the end of the semester just to get enough entries done or they would spend less time on rehearsal and practice before making actual recordings.
CONCLUSION
The results of this study reveal that students went through a series of blogging stages, including conceptualizing, brainstorming, articulation, monitoring, and evaluating, and used a wide variety of strategies to cope with blogging-related difficulties. In addition, students perceived blogging not only as a means of learning, but also as a means of self-presentation, information exchange, and social networking. Furthermore, the findings suggest that blogs constitute a dynamic forum that fosters extensive practice, learning motivation, authorship, and development of learning strategies.
Pedagogical relevance is an important driving force that can both motivate students to undertake an activity and maintain their interest in it (Barr, 2004). Students in language courses would be more likely to engage in blogging if they felt that maintaining a regular target language blog could enhance their language proficiency or that improved blog-based performance could improve their course grade. Whatever the case, educators should make informed decisions regarding the extent of integration of blogs with course content, for instance, should the blogs be central or a peripheral component of the course? Course design should take into account many blog-related issues. One such issue concerns whether teachers should assign specific topics to be addressed on blogs. Further research in this regard would be of interest to researchers and classroom teachers.
Finding a balance between meaning and form is another important issue in integrating blogs more fully into course content. The need to focus on form may vary depending on course objectives and task design. If the main purpose of blogging is to enhance self-confidence (that is, to reduce speaking anxiety), then educators should provide students with opportunities for free language exchanges. On the other hand, if the main purpose of blogging is to enhance awareness of form, teachers should encourage students to observe and to reflect on language use in their own and in others' blogs.
One of the limitations of the current study is that classroom-based blogging tends to have a limited audience. Participants in the study expressed their interest in having not only a greater number but also a greater variety of visitors to their blogs, not just classmates. They also expressed interest in interacting with native speakers of English. Future research could compare classroom-based blogging and 'real-world' blogging and examine its effect on language learning, learner attitudes, and interaction among bloggers.
Research on the possible contributions of blogs to language learning is still in its infancy. More research can help determine whether other factors such as gender, age, field of study, computer literacy, and learner personality have a significant effect on the blogging process. Moreover, studies comparing blog entries with classroom discourse could shed light on communication patterns in the blogosphere. Other questions that are not addressed in this study merit attention: Is speaking on a voice blog as anxiety-provoking as speaking to an audience face-to-face? Can students who are speaking on a voice blog develop similar sense of audience as they would when speaking to a group face-to-face? Finally, it would be useful to compare the advantages and disadvantages of educational blogs with other CMC and face-to-face communication. More research on different task types of blogging could clarify aspects of student blogging and help create better pedagogical approaches for various instructional purposes. Combining mobile devices with blogs might serve as another strategy that, by fostering "anywhere, anytime" learning, could render blogging more time-efficient (Geddes, 2004).
