Designing a problem solving based training in some specialized domain? Using bloom’s taxonomy? Not getting the results? Here is why…..All the way you may be using 1-dimesion of Anderson's revision to bloom’s taxonomy or always thinking that pyramid of cognitive processes (misunderstood as learning levels) is all that you need to design your course. This is because most of what educators were given in training consisted of a simple chart with the listing of levels and related accompanying verbs. Biggest misconception is assuming Anderson's revision to bloom's taxonomy as 1-dimensional. Whereas it is indeed 2-dimension. This mostly misunderstood or forgotten 2-dimesion is the key to problem solving. The biggest issue is that 60 year old system has some flaws and either flaws in that system are not properly published or not properly understood. This concise presentation should be able to provide instructional designer and training professional with a tool and right direction to use 2-D Taxonomy by Anderson for design of problem solving training.
