A study aid apparatus provides an academic outline that is arranged three dimensionally through the use of a number of moving parts. Several modules, each devoted to a separate category, are attached to the face of a base member so that the several different category headings can be seen simultaneously. Parts within a given module are manipulated to reveal subheadings, sub-subheadings, and so on. In this way, the invention provides study materials that mimic the workings of the human mind more accurately than do prior study materials, thereby enhancing a student's learning experience and increasing the likelihood of effective recall. In particular, the invention keeps information "in perspective," such that major concepts remain prominent at all times whereas minor details are suppressed until needed.
