Homework or not?

I read an article today about a teacher debating weather or not to grade his students homeowrk. And as his thoughts were that giving them homework was like giving them a test to do at home since it is going to be graded. He is thinking that grading homework might be old fashioned and needs to be looked at as just practice, not grades. My here is the article, http://101studiostreet.com/wordpress/?p=583 go ahead and read it, comment on this blog or his on what your thoughts are.
