How can blogs be used in the education system?

I think that blogs can be useful for teachers in the education system. Teachers can post their concerns about the education system and tips on what they think should be done. Blogs provide a better communication system between home and school life. Teachers can post their agenda for their class each day, which gives sudents the chance to see ahead of time what they are going to be learning. Blogs also give availability for parents to view the daily agendas and see what they are learning. Teachers can post homework assignments. This is good for many students need to be reminded what their homework consists of. Posting homework assignments also gives parents a chance to make sure their children are getting their homwork done. Teachers could also give a general overview of students attitudes and development process (without naming any names) everyday to see if there was an improvemnet over the year. Blogs give the chance for student and parent feedback. Overall, blogs can be useful in the education system.
