When learning is defined in these precise terms, it is possible for those whose responsibility it is to support students and ensure that learning takes place to apply methods which have been proved to minimize cognitive load and allow simple schema creation and the smooth transition of those schemas to long term memory. An accurate definition of learning allows the creation of an accurate definition of teaching and the possibility of producing evaluations of learning with greater validity. For these reasons, the discussion of what constitutes learning is an important one, and one to which Baddeley and Sweller have made perhaps the most significant contributions.
