Which of the following learner characteristics is highly related to…

Concept: Teaching is effective to the extent that it produces learning, and learning is constructive — new content is understood only when it is anchored to the concepts and skills the learner already holds. Ausubel put it as: the single most important factor influencing learning is what the learner already knows. So the learner variable that instruction must actually be matched to is the learner’s existing cognitive structure. Characteristics that sit inside the teaching–learning transaction act on effectiveness directly; characteristics of the learner’s home or social background act only indirectly, through mediating variables.

Application: Prior experience of the learner is precisely that existing stock of concepts, skills and earlier encounters with the subject matter. A teacher establishes it first (readiness testing, previous-knowledge questioning), then chooses the entry point, the examples, the pace, the scaffolding and the evaluation to build on it. This is the basis of the classical maxim of teaching “proceed from the known to the unknown”: when the lesson is pitched at what the learner already has, the new material is assimilated and the teaching produces learning; when it is pitched away from it, the same teaching produces little learning.

Cross-check — how the other learner characteristics offered here relate to effectiveness:

• Educational status of the parents of the learner — a socio-economic background indicator. It correlates with attainment in survey data, but it lies outside the classroom transaction and works only through mediators such as home support, resources and aspiration.

• Peer groups of the learner — a social-influence variable. It shapes attitudes, motivation and out-of-class conduct, so it too reaches learning only indirectly, and it is not what a lesson is planned around.

• Family size from which the learner comes — a demographic background indicator, linked to resources and adult attention at home. It is the most remote of the four from the act of teaching itself.

Result: The learner characteristic most closely related to the effectiveness of teaching is the learner’s prior experience — the readiness base on which every effective lesson is built.
