Learning by doing

The best way to learn is by doing. This is my second attempt at setting up a blog. I hope to learn more by doing, as well as reading other blogs. I'd like to use this as an instructional blog. I've read and seen how other educators are using blogs with their students. Not sure how to go about allowing student access from school. Need to decide on how to manage this with students, especially since I work with all the students at my school, not just one classroom.
