Identifies weaknesses of conceptual modelling languages for the problem domain of information systems (IS) development. Outlines an approach called facet modelling of real-world problem domains to deal with the complexity of contemporary analysis problems. Shows how facet models can be defined and visualized; discusses facet modelling in relation…

Shows how attention to transcending functions provides a new integrative approach to mathematics that can improve the critical thinking and problem-solving skills required for addressing large-scale problems. Contains 38 references. (DDR)

It is argued that mathematical modelling is important in teaching mathematics and that teachers have to create cultural support for it in the classroom. Posing an unsolvable problem for students may reveal the culture of the classroom as it exists, but its contribution to developing the needed culture that supports mathematical modelling appears…

It is argued that students who appear to ignore common sense and real-world knowledge in their approach to mathematics word problems in school are often behaving sensibly given the situation. The improvement of mathematics word problems for teaching will require changes in teacher beliefs and the use of modelling as an activity of organizing. (SLD)

This article describes a model to assist teachers in solving academic or behavioral problems of students with learning disabilities. The model uses the word PINPOINT as a mnemonic technique to address Problem identification, Importance rating, Noting the behaviors to develop, Possible solutions, Optimal options for the student, Ideal interventions…

Explains the Big6 model of information problem solving as a conceptual framework for learning and teaching information and technology skills. Highlights include information skills; examples of integrating technology in Big6 contexts; and the Big6 and the Internet, including email, listservs, chat, Web browsers, search engines, portals, Web…

Presents a typical cost-allocation problem with possible solutions, including geometric and combinatoric ones. Provides students with a real-life application of the mathematics that they know. (KHR)

Discusses the nature of tasks used to elicit the development of such systems by middle school students. Analyzes mathematical reasoning development of students across tasks and the diversity of thinking patterns identified on problem tasks. Discusses student reasoning about the relationships between and among quantities and their application in…

Presents a case study in which two 8th grade students developed knowledge for modeling a physical device called a winch. Demonstrates that students have and can use criteria for evaluating algebraic representations. Explains how students can develop modeling knowledge by coordinating criteria with knowledge for generating and using algebraic…

Describes similarities and differences between modeling cycles and stages of development. Includes examples of relevant constructs underlying children's developing ways of thinking about fractions, ratios, rates, proportions, or other mathematical ideas. Concludes that modeling cycles appear to be local or situated versions of the general stages…

The study with 989 learning-disabled students supported the cognitive-based arithmetic problem-solving model of Dinnel et al. under continuous visual stimulus conditions but suggested a more complex neuropsychological underpinning to arithmetic performance in both visual and aural stimulus conditions. (Author/DB)

Presents a problem-solving model for outdoor group leaders. Describes assessment, analytical and creative phases of the model, and emphasizes the importance of experience-based judgment. Discusses ways of providing experiential problem-solving opportunities in outdoor leadership preparation programs. (SV)

Discusses student difficulties in problem solving. Presents a structured approach to one-dimensional constant acceleration problems. Provides researcher's experience including an example problem, advantages of the approach, and student responses with two illustrations of problem solving. (YP)

Presents a library and information skills curriculum based on an information problem solving approach and Bloom's taxonomy of educational objectives in the cognitive domain. The taxonomy is described, and six information skills that match Bloom's six levels of cognition are identified. (12 references) (CLB)

The second response conditional probability model of decision-making strategies used by examinees answering multiple choice test items was revised. Increasing the number of distractors or providing distractors giving examinees (N=106) the option to follow the model improved results and gave a good fit to data for 29 of 30 items. (SLD)
