Draw the Relationship, Not a Decorative Study Poster
A useful diagram makes an idea easier to inspect. It does not need to look impressive on a wall.

The page has coloured headings, careful borders and a beautiful title. It took an hour to make. The relationship between the ideas is still unclear.
Give the picture a job
The Learning Scientists describe dual coding as combining verbal and visual representations. That does not mean decorating every sentence. An original diagram exercise begins with one question: what relationship is hard to understand in words alone?

For a process, draw a sequence with arrows and label what changes at each step. For a comparison, use two simple sketches and mark the difference. Keep the words that explain the visual; an unexplained arrow can hide uncertainty as easily as a vague paragraph.
Test it without the source
Put the textbook away and explain your diagram aloud. If you cannot say what a line means, revise it. If a symbol implies a connection the lesson never established, remove or check it.
The result may be untidy and useful. Its value is in making the structure visible and helping you explain it accurately. A study drawing is a thinking tool before it is an art project. Save the perfect lettering for a task where lettering is actually the point.
