integrating blogging to classes-my experiences

Merhaba
Last week was a very busy week for me because of my new class and my attempts to integrate blogging to my class. Almost 50% of my ss have blogs now but I have to admit that it took a lot of time to make them to get used to blogging. My intention of using blogging in my class is to make my ss produce sth in other words;to create them an opportunity t o use the new language they learn.I assigned them two writing tasks and many of them managed to complete them. However I'm not sure about how to correct them since they have serious mistakes.I don't want to discourage them but at the same time some mistakes have to be corrected. I sometimes post a general comment to my ss' blogs and write they need to revise their paragraphs again.I 'm thinking of some other solutions and checking B4B mails a lot to overcome that difficulty.I also think that I should involve my ss more in the class blog since it is easier to control what's going on.Videos,some reading texts , even voice messages can be useful in involving my ss in the class blog.I hope it works.
