Survey the material before you read

Spend a few minutes scanning headings, visuals, and summaries before reading a word.

Why it works

Previewing a chapter creates a skeletal schema — a rough mental map of what is coming. When you then encounter details, the brain can attach them to that structure rather than storing them as isolated facts. Schema theory shows that prior structure dramatically speeds encoding because new information slots into an existing framework instead of floating free.

How to do it

1. Read the chapter title, all headings, and all subheadings first.
2. Glance at figures, tables, captions, and any bold terms.
3. Read the first and last paragraph and any provided summary.
4. Stop: you have the map. Now open the text.

Evidence

Previewing activates prior knowledge and creates advance organizers, which Ausubel’s research showed improve retention of the material that follows. The mechanism (schema activation) is well established in cognitive psychology, though controlled studies on the SQ3R survey step in isolation are limited. (mechanistic)

Studies of SQ3R as a whole package show mixed results depending on implementation fidelity; the survey step is harder to isolate than the recitation step.

Common mistake

Treating the survey as the actual reading and moving on — the survey is a map, not the territory; it only works if you subsequently read for the details it primed you to expect.
