Learning abstract concepts through concrete examples may promote learning at the cost of inhibiting transfer. The present study investigated one approach to solving this problem: systematically varying superficial features of the examples. Participants learned to solve problems involving a mathematical concept by studying either superficially…

Three studies evaluated a method for developing prior-knowledge structures that prepares students to learn from a text or lecture. Findings indicate that there is a place for lectures and readings in the classroom if students have sufficiently differentiated domain knowledge to use the expository materials in a generative manner.

Examined the influence of college students' expertise on use of multiple documents about a historical controversy. Found that strategies did not differ significantly across the groups of expert and non-expert students. However, evaluation of usefulness varied as a function of document type and students' expertise. Furthermore, novices and experts…

This interview study gathered information about the prior knowledge and thinking of kindergarten to third- graders regarding the supply of water, heat, and light to modern homes. Findings indicated that students possessed only limited and spotty knowledge about utilities in modern homes. Within general trends, there was evidence of growth in…

Examined how high school students, in individual and peer conditions, process scientific information that contradicts what they believe, and assessed the contribution of this activity to conceptual change. Results indicated two processing approaches: (1) direct assimilation; and (2) knowledge building, suggesting that knowledge building as a…
