In the quest for deep thinking and understanding there is a time, place and space for the different modalities of learning. A classic example, being able to recognise the features of a paragraph and being able to write a paragraph. Each have their time and place, however. In my experience I have seen a fair percentage of educators misinterpret knowledge for understanding. And it makes me think, learning reinforces the importance of recall over understanding.
I therefore feel fortunate to work with a concept driven curriculum that through inquiry creates possibilities for deep thinking and understanding to emerge. Through the gradual release of responsibility a synergy can be formed between teacher and student. Used wisely, in a community of learning environment, the conceptual approach to teaching and learning can certainly reduce the work of the teacher; by how much depends on the individual. But, whatever percentage is achieved, the equal and opposite reaction will be freed up time to learn from the people you teach. Work < Learn!
