The science behind it: Deep Encoding Strategies

Encoding strategies are the techniques learners use to give new material meaning at the moment of study: connecting it to prior knowledge, imagery, emotion, or action.

Why it matters

How you encode determines what you will later be able to retrieve; shallow encoding (rote reading) yields shallow memory, deep encoding yields durable, flexible memory.

How to apply it

  • Rephrase new material in your own words before moving on.
  • Connect each new idea to at least one thing you already know.
  • Generate examples from your own life that illustrate the new concept.

Common mistakes

  • Re-reading the same sentences multiple times instead of re-encoding.
  • Highlighting and underlining without actively elaborating.
  • Treating passive note-taking as encoding, when notes are only useful if reviewed and reworked.
