Educational theories you must know. Bloom’s taxonomy. St.Emlyn’s

 

Bloom's taxonomy(1)You can legitimately argue that Bloom’s taxonomy is not a theory but is rather a classification system (that’s what taxonomy means after all) and that’s true, but it has relevance to how we think about education and what it is that we try to teach.

Bloom’s taxonomy has been updated many times since originally devised back in the 1956. The latest iterations still has the core themes but be careful which version you are looking at when reading around the subject.

The three core elements of the taxonomy are the cognitive, affective and psychomotor domains. Each of the domains has a hierachy of intellectual behaviour pertinent to that domain.

Cognitive (knowledge)

Affective (attitude and self)

Psychomotor (skills)

Each of these has a description of the levels of expertise but there is no doubt that most of the examples you will see and hear described link to the cognitive domains. I would argue that in emergency medicine and critical care all aspects are important and as educators creating a balanced curriculum and learning experience we need to be aware and ensure that we develop our learners in all areas.

This is the pre 2011 version but is still useful for the language used to describe how you might test the different levels in the cognitive domain.

The benefits of a classification system to educators is that we can see how the curriculum, learning activities and assessments fit into each of the domains. For example if we are teaching new starters then we may focus on simple acquisition of facts and in the testing of these. In contrast if we are teaching and testing advanced learning then we should be asking them how they evaluate and balance information. In emergency medicine we make many decisions on a shift and often with incomplete information. We therefore frequently have to function at very high levels within the cognitive domains, and at levels that require much more than the simple regurgitation of facts. Taking that together with Bloom’s taxonomy it can help us understand how, who, when and how we can teach that decision making, and of course how not to. MCQs are unlikely to be the right way to test our senior trainees and consultants.

So Bloom’s is useful when writing learning objectives and measurable learning outcomes and you can see some nice examples here. University courses can use the categories to decide appropriate level questions for different levels of students. For example by asking higher level questions on synthesis and creation to masters level students. This is most obviously seen in the way questions and learning objectives are phrased.

If you want something a bit more entertaining try Harry Potter.

 

Why Bloom’s taxonomy matters.

Bloom’s taxonomy can therefore be useful for us to check that we are teaching at the right level, to the right people and with the right assessments.
