Fading support promotes the transfer of responsibility from instructor to learner.¶

Claim · All claims
Evidence · 2 studies · 1 causal r?, 1 review r2 · q3

Fading, or the gradual withdrawal of support, is one way to move from studying examples to independent problem solving. The recorded experiments support this transition at least for near transfer; they do not establish that every scaffold must fade at one rate or that fading prevents long-term dependence.

Subclaims¶

q3 i? A review of a decade of scaffolding research names contingency, fading and transfer of responsibility as the three key characteristics of scaffolding, and describes responsibility as transferred to the learner through contingent fading; it defines this link conceptually and does not test whether fading causes the transfer. → van de Pol et al. 2010 q3 i? Across three experiments, fading worked examples into increasingly incomplete examples and then independent problems favored near-transfer performance over static example–problem arrangements; learning-phase errors and the direction of fading also mattered. → Renkl et al. 2002

This review of a decade of research on teacher–student scaffolding discerns contingency, fading and transfer of responsibility as the three key characteristics of scaffolding, and states that fading "is strongly related to" transfer of responsibility: "Via contingent fading, that is, responsibility for the performance of a task is gradually transferred to the learner." This is the review's conceptualisation of scaffolding; the studies it reviews do not isolate fading as the cause of transfer, and it reports that fading and transfer of responsibility were operationalised less often than contingency.

q3 · three experiments (one field, two laboratory) · i? · no common pooled effect reported here · n=20 ninth graders, 54 college students, and 45 college students across three experiments · causal · r?

Across a field experiment and two laboratory experiments, the authors compared a gradual transition from complete examples to increasingly incomplete examples and independent problems with static example–problem arrangements. Their results favored fading at least for near transfer; learning-phase errors played a role in mediating the effect, and removing the last worked-out steps first was more favorable than removing the first steps first. This is a report of three experiments, not one experiment with 71 participants, and it does not establish a universal far-transfer or fading-rate effect.

Studies bearing on this claim¶

Should support be withdrawn, and in what order? This table gathers the studies behind this claim and the 14 narrower claims that bear on it: 13 distinct studies (7 causal, 3 review, 1 qualitative, 1 quant-synthesis, 1 theoretical), q2–q3, 1 of 13 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.

Discussion¶

This is sometimes called the "completion effect" in cognitive load literature. However, fading must be carefully timed; removing support too early can cause cognitive overload.
