Adey, P and Shayer M (1994) Really Raising Standards, Routledge, London discussed  the development and success of the often forgotten and misunderstood programme C.A.S.E. The work they did on the Curriculum Analysis Taxonomy allowed for the development of a series of lessons deeply anchored in domain specific vocabulary, experiences and concepts. The instructional design was in modern parlance to reduce extraneous cognitive load, map and match the intrinsic load and use strongly teacher led activities and discussions to make a range of germane loads available. The goal was to activate the emerging thinking schema needed for successful learning into more abstract objectives. Preparing the mind for new learning. This is why many studies have shown the long and far transfer effects.
