Draw it yourself instead of copying

Generate your own rough sketch of an idea rather than viewing a finished diagram.

Why it works

Drawing an idea yourself combines dual coding with the generation effect: you must understand the content well enough to translate it into a spatial form, which forces deeper processing than passively viewing a polished figure. The act of deciding what goes where builds both the visual trace and a richer verbal understanding at the same time.

How to do it

1. After learning something, close the source and sketch it from memory.
2. Use crude shapes and arrows — artistic quality is irrelevant to the benefit.
3. Compare your sketch to the source and fix what you got wrong or left out.

Evidence

Research on drawing to learn finds that having learners generate their own drawings of material often improves memory more than viewing provided images or writing summaries, combining the effects of dual coding and active generation. (rct)

Drawing helps most when learners have enough understanding to produce a meaningful representation; for completely novel material a worked example may be needed first.

Common mistake

Tracing or recopying a textbook figure neatly, which feels productive but is passive and skips the understanding that generating your own drawing requires.
