Blogs are alright to use in the classroom. I say this because teachers can have class with someone else in another country. Teachers can also post assignments and students and parents can communicate with the teacher very easy.
Technology is good for the classroom. Because the whole world is preety much starting to be based around computers it's giving students an advance on how to use certain software. It has its down also because it is taking from funds that could go on better stuff for the school. Even more teachers can be hired if they didn't purchase computers.
