Challenging Bloom's Taxonomy

Have had a few thought provoking debates recently about the validity of Bloom's Taxonomy. Yes, that's right, a challenge to the orthodoxy! I've read through a selection of articles which all point to the fact that there is no real evidence base to support Bloom's theories and worse, thinking in this rigid, hierarchical way can even be damaging! Can it be true? One criticism is that it can lead to teachers not really thinking through the different categories of thinking skills each time they're used which lead students to think superficially. Any classification of skills along the lines of Bloom's can aid critical thinking but only if it is used critically. I guess my concern is that use of Bloom's Taxonomy has become wholly uncritical in many cases.

The SOLO (Structure of Observed Learning Outcomes) taxonomy is just as bad. I've written about my struggles with it here.
