Spend time in any school talking to teachers and even students about thinking and learning and you are likely to hear the phrase ‘Bloom's taxonomy' passed around. More than likely you will see it displayed on a wall as a set of processes learners engage with when working in the cognitive domain. Quite possibly it will be arranged in a pyramid or as a ladder with knowledge at the bottom and either evaluating or creating at the top. It might be labeled as 'High Order Thinking' and the teacher in the room is apt to inform you of how his or her students are encouraged to spend more time thinking towards the top of the ladder than the bottom. Despite the enthusiasm many teachers have for Bloom’s and the work of its lead author Benjamin, few educators have read the ‘Handbook’ that outlines its structure and most of the lovely posters leave out two key components.
