I guess there is something wrong with my laptop. I tried to add something on Wiki, but it didnt work. I had to keep refreshing it…
I think Wiki is more formal than blog. Blog is like a medium where students could communicate their ideas and what they thought. Wiki could be more formal that teachers could post the whole curriculum and brief lesson plans on it. Moreover, students could involve in the construction of learning. That is to say, Wiki is not only resource of language learning, but also a medium that students could share their understanding about language.
