The modeling instruction pedagogy for the teaching of physics has been proven to be quite effective at increasing the conceptual understanding and problem-solving abilities of students to a much greater extent than that of nonmodeling students. Little research has been conducted concerning the cognitive and metacognitive skills that modeling…

Investigates the evidence that the imperfect performance in forward search of 36 children aged four and five years resulted from unstable execution of the correct component processes. Evidence suggests that five-year-olds engaged in forward search, but four-year-olds used only a rudimentary form of forward search. (RJC)

An alternative is suggested to conventional and propositional ways of thinking about curriculum matters. Curriculum theory is conventionally presented as statements of propositional knowledge even though the significance of tacit, non-propositional knowledge has been recognized in philosophy. It is suggested that attention be paid to how teachers…

Collected qualitative data through interviews and triad elicitation with 5-year-olds in London to determine children's current knowledge and understanding of their "making" activity and of Lego construction kit components. Data provided triangulation for another study that found that young children could achieve a great deal with…

Explores the utility of mental models as learning outcomes in using complex and situated learning environments. Describes two studies: one aimed at eliciting mental models in the heads of novice refrigeration technicians, and the other an ethnographic study eliciting knowledge and models within the community of experienced refrigeration…

A study examined the application and availability of clinical and biomedical knowledge in the clinical reasoning of physicians as well as possible mechanisms responsible for changes in the organization of clinical and biomedical knowledge in the development from novice to expert. Subjects were 28 students (10 second year, 8 fourth year, and 10…

The paper presents the thesis that experienced physicians, while diagnosing routine cases, are operating upon knowledge structures that are distinctively different from those of novice physicians and students. In the course of their medical training, students develop rich, elaborated causal networks, explaining the causes and consequences of…

A study investigated the known phenomenon of "intermediate effect" in which medical students with an intermediate amount of knowledge and experience demonstrate higher amounts of recall of the text of a medical case than either experienced clinicians or novices. In this study the amount of activation of prior knowledge was controlled by…

In two studies, the role of biomedical knowledge in the diagnosis of clinical cases by physicians and medical students was explored. Experiment 1 demonstrated a decrease in the use of biomedical knowledge with increasing expertise. This result appeared to be at variance with some findings reported in some but not all of the literature. In…

The processes by which conceptual knowledge is constructed during mathematical problem solving were studied, focusing on the cognitive activity of learners (i.e., the ways they elaborate, reorganize, and reconceptualize their solution activity). Underlying this research is the view that learners' mathematical conceptions evolve from their activity…

Scientific and everyday knowledge domains are compared so as to reveal the distinctive differences between their goals and the cognitive processes used to attain them. The main goals, working goals, learning difficulties, knowledge structure, concept specification, knowledge organization, role of school science, program-solving instruction, formal…

Cognitive psychologists and measurement specialists have identified several methods for assessing students' knowledge structures. Applications of the Concept Structure Analysis Technique and MicroCAM (a computer-aided method) are described. Other research into schema knowledge is noted. These assessment procedures provide information about student…

This paper reviewed literature on cognition to help art teachers understand what they can learn from the huge body of literature that has been generated by cognitive psychologists. It is argued that, in this information society, teaching memorization skills is not enough; students must learn problem-solving skills. A long list of specific thinking…

External representations have a great impact on what and how students learn. One key manner in which environments can operate upon novices' knowledge is through helping them ground their problem solving in an understanding of the situation embodied by the problem. In this paper, students' difficulties in microeconomics problem solving were…

Trends in emphases in the study of clinical reasoning are examined, with attention to three major branches of research: problem-solving, knowledge engineering, and propositional analysis. There has been a general progression from a focus on the generic form of clinical reasoning to an emphasis on medical content that supports the reasoning…
