Evidence quality · No study behind this claim is a peer-reviewed article with a DOI: it rests on an ERIC document (a report, conference paper or thesis). It is kept because 2 design pages cite it; treat it as a lead to check, not an established finding.
Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Learning from a map yields global spatial-relation images, while learning through navigation yields route knowledge. → Shavelson 1986
Evidence¶
Shavelson 1986¶

q2 · i? · review · r2
The review reports, citing Thorndyke and Hayes-Roth's (1982) map-learning study, that people acquire different knowledge from different media, calling this the closest indirect evidence for symbolic encoding specificity; the review states it cannot find research directly related to symbolic encoding specificity.
"when learning from a map, people encode global spatial relations, images that can be scanned and measured like a physical map; whereas when learning through navigation, people acquire knowledge about the routes"
Discussion¶
Related Claims¶
- Proposition 4: evidence gathered through distinct demands supports capability claims better than multiple records of the same performance — the general claim this finding bears on, with the studies behind it
- In one 37-student classroom experiment, recall and retention differ across media combinations in the direction Dual Coding Theory predicts — related
- The direct-to-vicarious and purely symbolic experience continuum remains valid while the cone's description of media is dated — related
- Typical verbal achievement tests may underestimate students' subject-matter knowledge because of a mismatch between the test's symbolic form and students' symbolic encoding — related
- Adding relevant pictures or graphics to text improves learning from it, with a small pooled effect on reading comprehension, though whether dual coding explains the benefit is disputed — related
