Being a first time blogger this is all making my head spin but I can see great ways I can use this.
Delicious could be used as a way of listing sites that students could go to (I think). For example maybe you have a list of maths websites you want them to go to.
My students are reluctant to express how they are feeling about their work and learning but I am sure they would love to do a blog.
Now all I need is a few extra hours in the day to learn all this.
