Investigates high school students' understanding of the physical relationship of chromosomes and genes as expressed in their conceptual models and in their ability to manipulate the models to explain solutions to dihybrid cross problems. Describes three typical models and three students' reasoning processes. Discusses four implications. (YP)

Presents model of instructional strategy planning that links specific cognitive learning and thinking processes with specific computer-based instructional strategies. Topics discussed include memory systems; types of knowledge; drill and practice; tutorials; task-oriented simulations; problem-oriented simulations; and self directed experiences.…

This paper establishes a conceptual framework for assessing problem-solving abilities of gifted secondary students. Assessment procedures based on a continuum of problem types are described. Issues discussed include multiple types of intelligence, the use of multiple measures, sensitivity to individual differences, and assessment for the student's…

A model of transformational change in education is presented and implications for guiding students to higher levels of communication, critical thinking, problem solving, interpersonal relationships, and creativity are explored. (AEF)

Dozens of Australian "laptop" schools are following the lead of Methodist Ladies' College (an independent pre-K-12 school) in personal computing and are using some of their pioneering professional development models, including in-classroom collaboration, "slumber parties," and build-a-book workshops. Guidelines for implementing…

Argues for a reconceptualization of teaching expertise based on psychological similarities of expert teachers to one another. The authors offer a prototype-based categorization model, drawn from psychological research, on which the family resemblance among expert teachers may be founded. The authors discuss several implications of the prototype…

Suggests that a reductionist and mechanistic epistemology of present Environmental Education (EE) systems impedes the ability of EE to be an agent of environmental problem solving. Using an action research approach, presents EE as a transforming agent to enable epistemological change. (22 references) (Author/MCO)

This paper reviews trends in research into creativity and describes the Profiling Project which is examining Creative Problem Solving (CPS), an ecologically based process model used to define problems, generate ideas, and refine solutions. Research into five dimensions of CPS are proposed: the situational outlook, personal orientation, outcomes,…

Problem-solving models in memories of 11 good and 12 poor novice first-year university students were studied. The students reconstructed physics problems seen briefly, relying on models in memory. Both good and poor students had models of problem situations at their disposal, but good students performed better than poor students. (SLD)

Presents an analysis of the question in the title which involves a discussion of fractions, number theory, and probability through modeling, exploring, and other mathematical connections. (MKR)

Discusses three evolving paradigms for supporting learning and work performance: instructional design, performance support, and network systems. Describes an overall trend toward greater flexibility and empowerment, and shows how each paradigm reflects the technologies available at the time of its initial development. (AEF)

Studied the use of a problem-posing model in health education. The model based on the ideas of Paulo Freire is presented. Four innovative experiences of teaching-learning in environmental and occupational health and patient education are reported. Notes that the problem-posing model has the capability to transform health-education practice.…

Presents an outline of models of information seeking and other aspects of information behavior, showing the relationship between communication and information behavior in general with information seeking and information searching in information-retrieval systems. Also presents an alternative, problem-solving model which provides a basis for…

U.S. mathematics education has been criticized for being too broad. This article examines ways middle school students use simple problems and situations to foster a deeper understanding of underlying concepts. Presents a sample area and perimeter problem, describes extending the problem using tiles to determine minimum perimeter, and discusses…

Explores what an emphasis on reading as social practice can tell us about the nature of reading. The article maintains that what counts as a "proper" reading of the text is highly constrained by the classroom context and that classrooms should be discourse sites where specific ways of reading are required and particular regimes of…
