I found this diagram of Bloom’s Taxonomy a few years back and still think it is the best hierarchy and explanation I have seen:
For those of you who aren’t familiar, a group of educators created Bloom’s Taxonomy in the 1950′s to classify and standardize scaffolding learning objectives:
It refers to a classification of the different objectives that educators set for students (learning objectives). Bloom’s Taxonomy divides educational objectives into three “domains”: Cognitive, Affective, and Psychomotor (sometimes loosely described as knowing/head, feeling/heart and doing/hands respectively). Within the domains, learning at the higher levels is dependent on having attained prerequisite knowledge and skills at lower levels. A goal of Bloom’s Taxonomy is to motivate educators to focus on all three domains, creating a more holistic form of education.
It is still very much in use and considered a backbone of sorts to curriculum development and assessment. Bloom’s will be an essential reference for contextualizing my thesis in formal and informal learning environments (though I think I am sticking with the latter) and for evaluating the growth of participant-learners.
