Illustrates how a novel problem of chemical equilibrium based on a closely related sequence of items can facilitate students' conceptual understanding. Students were presented with a chemical reaction in equilibrium to which a reactant was added as an external effect. Three studies were conducted to assess alternative conceptions. (Author/SAH)

Suggests that the study of microdevelopment offers a potentially powerful way to relate learning and development where similar changes occur but in differing time frames. Microdevelopment analyzes short-term changes as developmental functions. Individuals and groups function at widely different developmental levels and grow in diverse nonlinear…

Explores the types of problem-solving strategy knowledge that can be accessed through the complementary use of two forms of verbal reports: concurrent verbal protocols and retrospective debriefings. Data collected from students and professors provides a detailed account of problem-solving strategies used, as well as the conditional knowledge,…

Asserts that traditional strategies of problem-solving are inadequate and that a new method is needed. Suggests four ways to redirect attention in problem solving: overcoming an instant or linear perception of time, interacting between the problem's components and its whole, searching for the meaning or sense of a problem, and studying the…

Discusses a sample puzzle activity called "Thinking Like an Artist" that encourages careful observation of artwork and prompts students to decode the thought processes used by artists. Helps students develop original ideas and strengthens their problem-solving abilities. Provides a list of materials, rules, and the procedure in detail. (CMK)

This study explored relationship between working memory (WM) and mathematical problem solving, comparing children with learning disabilities (LD) to chronologically age-matched and younger achievement-matched children on measures of WM, phonological processing, problem-solving, and word problem-solving accuracy. Found support for notion that…

Reports on two related studies intended to explore the interactions among children's metacognitive abilities, their working memory capacity, the development and selection of strategies, and their performance on problem-solving tasks. Explains that in study 1 children performed a reclassification task, and in study 2 children performed a…

Tower of Hanoi has become a popular tool in cognitive and neuropsychology to assess a set of behaviors collectively referred to as executive functions. Substantial variability in performance on the Tower of Hanoi (TOH) disk-transfer task among normally functioning young adults, and potential contributions to these individual differences, were…

Similarity underlies fundamental cognitive capabilities such as memory, categorization, decision making, problem solving, and reasoning. Although recent approaches to similarity appreciate the structure of mental representations, they differ in the processes posited to operate over these representations. We present an experiment that…

The conditions under which explicit instruction in checking, combined with worked examples, may be beneficial in learning how to translate sentences into algebraic equations was examined from the perspective of cognitive load theory. In two experiments it was shown that Grade 8 and 9 students were initially disadvantaged by the inclusion of a…

This paper concisely chronicles the evolution of the concept of expertise since the 1960s. After presenting the key themes of expertise throughout the years, we propose a breakdown of the evolution into three waves: information-processing wave, speed/problem solving wave, and emotional intelligence/ways of expertise wave. We then show the…

This research examined students' responses to mathematics problem-solving tasks and applied a general multidimensional IRT model at the response category level. In doing so, cognitive processes were identified and modelled through item response modelling to extract more information than would be provided using conventional practices in scoring…

This article discusses situated cognition research and its impact on literacy studies concepts and instruction. It provides a brief historical comparison of cognitive psychology and situated cognition and emphasizes the importance of understanding the complex relationships that exist between learners, the settings in which they engage in cognitive…

Worldwide interest in work and learning is generating a large volume of disparate disconnected studies which can help improve the understanding of both work and learning as separate domains, but which lack an overall perspective. This paper proposes the outline of a conceptual framework for relating work and learning by an individual worker as a…

The possible use of a calendar algorithm was assessed in DBC, an autistic "savant" of normal measured intelligence. Testing of all the dates in a year revealed a random distribution of errors. Re-testing DBC on the same dates one year later shows that his errors were not stable across time. Finally, DBC was able to answer "reversed" questions that…
