We studied Bloom's Taxonomy in grad school and I wanted to review it and found this website. Check out the Cognitive Learning domain table with the simplest to the most complex...sometimes, the level of the student or the material will require knowledge testing, but analysis, synthesis and evaluation are preferred with testing critical thinking. If you organize your objectives this way it will also help when you test. When I ask questions in class, I will inform them what level they had just answered the question at i.e. analysis level....I don't do it all the time or it would bring them to boredom, but occasionally I do.
Hope this helps you,
Barbara
