Extract a generalizable principle from what you observed

After observing what happened, ask: "What general rule does this experience support or challenge?"

Why it works

Abstract conceptualization is Kolb’s term for the step that converts observations into portable knowledge — a principle, a heuristic, a revised model. Without this step, reflection produces insight about one event but not transferable learning. The cognitive process is essentially inductive reasoning: what do multiple observations suggest about the underlying pattern?

How to do it

1. Review your reflective observations from the previous step.
2. Ask: "If I generalize from this, what rule or principle does it suggest?"
3. Check the principle against other experiences: does it hold, or does it need qualifying?
4. Write the principle explicitly — "When X, then Y tends to happen because Z."

Evidence

The value of generating explicit principles from experience is supported by research on analogical learning and on the generation effect: self-derived principles show better retention and transfer than received ones. The generation effect was demonstrated experimentally by Slamecka and Graf (1978), and Gick and Holyoak (1983) showed that inducing an explicit schema is what enables transfer to a new problem — the precise cognitive move this practice asks for. Kolb’s specific stage model is a theoretical organization of these processes. (mechanistic)

Kolb’s four-stage model and associated learning-styles instrument have been criticized on psychometric grounds; the usefulness of distinguishing stages explicitly is theoretical rather than empirically isolated.

Common mistake

Ending reflection at the observational stage — "I noticed that X happened" — without extracting a generalizable principle, so the insight belongs to that event only and cannot be applied forward.
