A student must recognize and correct these discrepancies if he or she is to reuse the design successfully. Eventually, the database will contain many example designs that span the range of naive conceptions of the design problem and related mathematical concepts. Studying multiple designs, may assist students in recognizing and avoiding imperfections in their designs. As noted, the database contains much more than example designs. Why provides design rationale.
Details provides detailed sub-designs.
Other Examples provides links to alternatives. Learning Issues contains notes about open issues and evaluations by the designer, peers, and the teacher. Notes in the database can be graphics, text, or digital video, as appropriate to what is being conveyed. Taken together, a sequence of notes comprises a design episode, whose components are indexed by the task model. The student creates and documents his or her design in a separate database that has a structure identical to that of the performance support database.
