EXD.3:1 - Problem frame

Use this pattern when a warranted account is available but the recipient has difficulty following its relations through the chosen words, symbols, diagram, demonstration or combination. It also helps when preparing an explanation whose several representations must work together.

Begin by selecting the relation the recipient must recover and the contribution each representation should make. Construct the correspondence at the point where the recipient needs it. The first useful result is an explanation in one sufficient form or a coordinated combination, with its conditions and losses visible.

A missing premise or derivation is a content problem. Obtain that contribution before treating the difficulty as a presentation choice.
