There is substantial empirical evidence showing the impact of the type of numbers in the solution of problems with a multiplicative structure. The theory of the intuitive models of arithmetic operations is today the most plausible theoretical account for these findings. In an attempt to contribute to a better understanding of the effects of number…

The Arizona Essential Skills states that development of problem-solving ability is the top priority of mathematics education. This study presents results of a survey of 744 K-8 teachers--631 females and 113 males--designed to investigate the current nature of mathematical problem-solving instruction in Arizona K-8 classrooms and the extent to…

The Calculators in Primary Mathematics Project was a long-term investigation into the effects of the introduction of calculators on the learning and teaching of primary mathematics. The Australian project commenced with children who were in kindergarten and grade 1 in 1990, moving up through the schools to grade 4 level by 1993. Children were…

This collection of four papers deals with problem solving and the measurement of problem solving. "Climbing Up the Competence Ladder: Some Thoughts on Meaningful Assessment of Problem-Solving Tasks in the Classroom" by K. C. Cheung uses the metaphor of a competence ladder to represent the problem-solving continuum with progressive…

This report presents a summary of research being conducted at the University of Minnesota in which new technologies are being applied to development of cognition in hearing impaired learners. The study involved an application of concept analysis, information-processing theories, and group-based interactive technology in the teaching of…

Based on suggestions of participants at the second annual Instructional Methods Forum held in June 1989, the monograph considers cognitive-based approaches to teaching mathematics to students with learning problems. It addresses identification of characteristics of successful cognitive approaches and the role of media and materials. An…

The roles of cognition and metacognition were examined in the mathematical problem-solving behaviors of students as they worked in small groups. As an outcome, a framework that links the literature of cognitive science and mathematical problem solving was developed for protocol analysis of mathematical problem solving. Within this framework, each…

This module is the sixth in a series of 12 learning modules designed to teach occupational mathematics. Blocks of informative material and rules are followed by examples and practice problems. The solutions to the practice problems are found at the end of the module. Specific topics covered include calculator division, mixed number fractions,…

These materials were developed for use in workshops with teachers. The document suggests a four-stage framework which students can apply to problems: (1) get to know the problem; (2) choose what to do; (3) do it; and (4) look back. Suggestions are included for each of the four stages of the probem solving process. Other specific techniques for…

Identifies proportionality as a powerful problem solving tool that students can apply in familiar situations but cannot apply in unfamiliar contexts. Gives an operational definition of proportionality from examples in introductory chemistry. Provides examples of direct proportions and how to evaluate variables to teach proportional reasoning. (CW)

In this lesson, students identify the question-answer relationship (QAR) for word problems that relate to a graphic or table. They then use the QAR strategy to determine the mathematical and cognitive actions required to answer the word problem. This activity is particularly appropriate for fourth- and fifth-grade students. During two 40-minute…

This study investigated the strategies subjects adopted to solve STEM-equivalent SAT-Mathematics (SAT-M) word problems in constructed-response (CR) and multiple-choice (MC) formats. Parallel test forms of CR and MC items were administered to subjects representing a range of mathematical abilities. Format-related differences in difficulty were more…

Presents ways to stimulate teachers to try several techniques for having students write their own problems and verify their meanings with others to become effective mathematics problem solvers. These techniques include sharing self-generated problems in a Mathematician's Circle and publishing problems on worksheets. (PVD)

Hypothesizes that exploring the mathematical ideas behind mathematical terms enables children to gain insight into the structure of a number system and provides a basis for powerful playing with this structure. Describes visualizing mathematical ideas for exploring aspects of mathematics. Offers rectangular numbers to link and explore structures…

Applications of generalizations of both arithmetic and geometric progressions are presented. The first-order difference equation is used in solving seven examples from finance, business, and medicine. Detailed directions are included for each example. (KR)
