Evidence for Basic Concept Maps #

Every substantive claim on the Basic Concept Maps page is checked against current research. Here is each claim, how well today’s evidence supports it, and the sources. The full, de-duplicated source list lives on the references page.

Supported · strong evidence — The benefit of a concept map comes from building it – the active work of selecting what matters, organising it into a structure, and integrating it with prior knowledge – not from how it looks (shape, colour, layout); this is generative learning.

Fiorella & Mayer’s (2016) generative-learning framework specifies the select-organise-integrate (SOI) processes by which learners build understanding, and lists mapping among the eight strategies that promote it. The claim that the learning comes from the constructive cognitive work rather than the surface appearance of the artefact is well supported by this framework and by the companion book (Fiorella & Mayer 2015). The surface features (colour, neatness) are not the active ingredient. Strong as a principle.

Supported · strong evidence — A map you build yourself beats one you only copy, and constructing maps produces more learning than viewing or studying ready-made ones.

Schroeder, Nesbit, Anguiano & Adesope’s (2018) meta-analysis (142 effect sizes, n=11,814) found an overall moderate benefit for learning with concept maps (g=0.58) and, in the key moderator, that creating maps (g=0.72) outperformed studying ready-made maps (g=0.43). This directly supports ‘constructing beats viewing’. Nesbit & Adesope (2006) likewise found construction conditions among the more effective uses. The directional claim is robust; the overall magnitude is moderate, but the construct-vs-study contrast is consistent and well evidenced, so strong for the directional claim.

Supported · strong evidence — The single best move is to build a map from memory first, then check it against the source – because the retrieval attempt, not the copying, is where the learning happens.

Karpicke & Blunt (2011, Science) found retrieval practice produced more learning than elaborative concept mapping with the source available; building a map from memory before checking turns the mapping exercise into retrieval practice, the strongest and most replicated study strategy. This ‘build-then-check’ instruction, repeated in the page’s exercises, is exactly the evidence-based reframing.

Supported · moderate evidence — Laying ideas out in space alongside words gives a second route back to them (combining a verbal and a visual-spatial representation aids learning).

The idea that a spatial/diagrammatic representation paired with verbal material provides an additional, complementary encoding route is grounded in multimedia-learning and dual-channel theory (Mayer 2009). The general principle is well supported, but benefits are conditional (coherence, signalling, expertise and the way the visual is constructed all moderate the effect), and a map can also add extraneous load if cluttered – hence moderate rather than strong, and why the page stresses that the construction, not the decoration, is what matters.
