Analogies between old and new concepts are common during classroom instruction. Previous transfer studies focused on how features of initial learning guide later, spontaneous transfer to new problem solving. We argue for a shift in the focus of analogical-transfer research toward understanding how to best support analogical transfer from previous…

This article examines the acquisition of Spanish idioms in a classroom setting that was supplemented with explicit instruction over a 10-week period. The research design manipulated two variables: prior lexical knowledge and idiom organization. Sixty-five second language (L2) learners completed pre- and posttests that measured their ability to…

Background: Various studies on analogical problem solving have shown that children can be taught to use analogies within a single session, but it is not known whether they can be taught a strategy for using analogical problem solving that persists over a period of time. Aim: Our study focused on the effects of prior assistance in analogy use on…

Slavery in the pre-Civil War United States is a hard topic to teach, not only because it raises issues of racism and injustice, but also because students assume so much. Often, they think all northerners were abolitionists or "good guys" and southerners were "bad guys" who enslaved African Americans because they viewed them as inferior. England,…

This paper describes the conceptualizations, or mental models, of the nature of the bonding and structure of metals of a group of U.K. college students. It is suggested that these mental models may be understood in terms of the students' prior learning about covalent and ionic bonding, and the prevalence of a common alternative conceptual…
