Visual scenes for teaching a plurality of polysemous symbol sequences and corresponding rationales

An apparatus, comprising:

• an integrated input and display device configured to provide polysemous symbols for selection on an initial electronic screen overlay displayed on a display;
• a memory to store a plurality of the selectable polysemous symbols in association with a pointer identifying display of an electronic screen overlay which is different from the initial electronic screen overlay;
• and
• a processor configured to
• control display of a second electronic screen overlay on the integrated input and display device, in response to an initial selection of one of the provided polysemous symbols, the second electronic screen overlay being the electronic screen overlay associated with the selected polysemous symbol, the memory being further configured to store a plurality of visual scenes, each respective one of the plurality of visual scenes being stored in association with at least two symbol sequences beginning with the initially selected polysemous symbol, and
• control display of one of the plurality of visual scenes on the integrated input and display device, in response to selection of one of the symbols on the displayed second electronic screen overlay, the displayed visual scene being stored in the memory in association with at least two symbol sequences including, in sequence, the initially selected polysemous symbol and the selected one of the symbols on the displayed second electronic screen overlay.
