I did a project last year on threaded discussion groups. I read an article about it in The Journal of Adolescent Literacy. It sounded like it would be very motivating for students, but I had no idea how to actually implement it. At the end of this last school year my students were participating in lit. circles. I thought it would have been great if they could have discussed the books they were reading with their friends in other classes. Next year I'd like to set up a blog for all of my students to participate in, I don't know how to set up the list of participants though. I think it was in the settings menu, I'll have to play with it some more.
I agree with the IKids article. Our students are so use to having all kinds of technology at their disposal, they have a hard time funcitoning without it. I went to several workshops for special ed. this past year and they all recommended letting LD and ADD students use alpha smarts or a computer to do their writing. I saw a big difference in the content of my students' writing when I finally started giving them the option of using the alpha smarts. I think blooging would be even better because they would have a bigger audience for their repsonses and they would be more motivated to make sure their writing made sense.
