Problem solving hierarchy (McKay 2000a p.160). This figure represents the strategic programming knowledge required for writing a new PASCAL program. Instructional modules provide the anticipated instructional outcomes required to demonstrate strategic programming knowledge. Commencing from the bottom of the figure they include: • the entry level skills: basic computer literacy. • problem solving: redefining the problem to prepare an algorithm. • knowledge of the programming language rules. Each module identifies a sequence of tasks necessary to achieve the instructional outcome. The learning hierarchy is described in full in the McKay 2000a thesis – see from page 158
