I think Bloom's Taxonomy is a great way to think about the steps required that it really takes to learn something from memorization through evaluation. There is a good Web site that summarizes Bloom (actually there are a lot of Web sites that do that). The site I happened on talks about the change in Bloom by one of his students to have the ultimate level of creating rather than evaluation. The site also talks about showing the progressive levels of attitude and skills. I like all three pyramids as an organizing principal. See http://www.nwlink.com/~donclark/hrd/bloom.html.
