A few ideas regarding the final project

I have a few ideas regarding the final project:

1) the use of dialogue journals in teaching writing in ESL classes

2) using technology to teach writing (exploring various methods within the scope of "technology")

3) how to avoid plagiarism in L2 writing

Of the above, I am leaning toward the first idea. I came across this idea a couple of years ago when researching a topic for a writing pedagogy course, and I have been waiting for an opportunity to explore this subject further.

I would like to find out how much this method has actually been used in ESL classes, whether many teachers have employed "email" as the mode of journaling, and if any measurable results regarding improvement in student writing ability have been noted. (I'm interested in the students' perceptions of their ability, their motivation to write, and the teacher's analysis of their improvement over the time period in which they were involved in the journaling.)
