Evidence from video tapes of experts thinking aloud and using analogies in scientific problem solving is presented. Four processes appear to be important in using an analogy: (1) generating the analogy; (2) establishing confidence in the validity of the analogy relation; (3) understanding the analogous case; and (4) applying findings to the…

This paper attempts to show that it is possible to analyze a problem solving protocol in which the subject spontaneously generates a series of analogies. The qualitative physics problem given to the subject describes a situation where that which is unfamiliar is often solved by relating it to several analogous situations that are more familiar.…

This paper posits a cognitive model for understanding and learning physics that is an alternative to the formal deductive system. Recent findings of Fuller, Karplus, Lawson, and others are cited in arguing against using a formal deductive approach to teaching physics. The model demonstrates types of action-oriented knowledge structures as they…

In this paper examples of the role of analogical reasoning in expert problem solving are presented. These are intended to show that using an analogy can change an expert's understanding of a problem situation by changing the conceptual model he or she uses to think about the situation. This suggests that using a good analogy may allow students to…

This paper presents evidence to indicate that spontaneously generated analogies can play a significant role in the problem solving process of scientifically trained individuals. In addition, it is suggested that these individuals exhibit more than one method for generating analogies. Ten scientists (representing physics, mathematics, and computer…

In this study 34 spontaneous analogies produced by 16 college freshmen while solving qualitative physics problems are analyzed. A number of the analogies were invalid in the sense that they led to an incorrect answer from the physicist's point of view. However, many were valid, and a few were powerful in the sense that they seemed not only to help…

Three purposes of this study were to: (1) propose some organizing theoretical and observational definitions of the anchor construct; (2) present some initial findings from a diagnostic test designed to uncover anchors for high school physics instruction; and (3) provoke an initial discussion of the new methodological issues that arise in this…
