Today I created a document/lesson plan to help me as I am introducing blogging to my upper level spanish students. I had them create a blog and then they must write a post at least once a week...in Spanish of course.
I also like the fact that you can create presentations on google docs. It offers a solution for those that do not have microsoft programs on their home computers. I assign a lot of presentation projects for my spanish 4 & 5 classes and I plan to have them use google docs this time so that they can collaborate together.
