Instructors are constantly baffled by the fact that two students who are sitting in the same class, who have access to the same materials, can come to understand a particular chemistry concept differently. Variation theory offers a theoretical framework from which to explore possible variations in experience and the resulting differences in…

Reflecting recent widespread interest in schema theory, this bibliography is intended to assist anyone interested in how the topic relates to reading. The introduction defines schema theory as the study of generic knowledge structures--called schemata--which are composed of "slots" or "placeholders" for each component, and…

The focus of this study was to portray the ideas that students with four years experience in learning physics developed in regard to the second law of thermodynamics. Data were obtained through 34 clinical interviews with grade 10 students. An analysis of student arguments revealed deeply rooted difficulties in using concepts that were learned in…

Using schema theory as a contextual framework, three studies were conducted to examine the effects of two triggering mechanisms on transfer of learning across two noncontiguous passages: similar terminology for shared concepts and a brief review of the first passage read immediately before the second passage. The first two studies served to pilot…

A dominant theme in cognitive psychology is that prior knowledge in long-term memory has a strong influence on an individual's cognitive processing. Citing numerous memory studies with children, knowledge base effects are presented as part of a broader picture of memory development. Using the sort/recall procedure (asking subjects to group sets of…

Reviews the current literature concerning prior knowledge in an attempt to clarify problems with the terminology. Identifies the three main problems: lack of definition or vagueness, nominal versus real definitions, and different names/same constructs or same name/different constructs. Includes a conceptual map of prior knowledge terminology. (MJP)
