As you all know, the concept ideas get better with feedback. Most of the time we do it in class and it is not documented and maybe sometimes forgotten.
In order to avoid this, Everybody will post his/her presentation to the blog (either as video or pdf in slideshare) so then other’s will write their ideas/comments about your presentation. In order to make this happen, during the your peer’s presentations in class you will take some notes of your feedback so then you can make use of your notes to write post your comment.
Same is true for small and final projects :)
And this is a significant part of your learning process.
