A cross-sectional study of educated men and women showed that cautiousness, as measured by perceived problem-solving ability, does not increase with age. Sex differences were nonsignificant. The results are discussed in terms of R. Schultz and J. Heckhausen's Life Span Model of Successful Aging. (Contains 28 references and 1 table.) (Author)

Describes service-learning programs in three schools: Sullivan Elementary School in North Adams, Massachusetts; Turner Middle School in southwest Philadelphia; and Miami High School in Oklahoma. Identifies common elements in the three programs. Describes what school boards can do to support service-learning programs in their districts. (PKP)

Offers a tangible suggestion for how dot paper can be used to implement an exploratory approach to problem solving in middle school geometry. Presents some intriguing mathematical tasks that demonstrate the elegance of mathematics, the usefulness of dot paper as a teaching tool, and the value of divergent thinking approaches to problem solving.…

Identifies the misunderstandings and problem-solving strategies of secondary students when solving stoichiometry problems. (Author/CCM)

Three experiments tested 21- and 27-month olds' ability to construct a path to a mentally re-presented goal. After seeing the goal-state configuration of problems, both age groups evinced planning. Demonstration of initial solution step was less effective than goal-state exposure. Even with specification of a greater proportion of the goal path,…

Finds that many activities that have been called "problems" are merely exercises or tricks. Offers a clearer definition of the word "problem". Notes some of the classroom implications of the new insight. (Author/CCM)

Describes a fourth-generation ISD (instructional systems development) model, an integrative problem solving system that dynamically adjusts the authoring activities of instructional development by direct reference to a specific learning problem or need. Includes case studies that illustrate the three model components: situational evaluation,…

Presents responses to a problem appearing in the December, 1998 issue on the concept of determining all possibilities for colored and numbered wristbands for students. (ASK)

Discusses a program that offers students a phenomenon-oriented environment expressed in the fundamental concepts and language of chemical engineering such as mass and energy balancing, phase equilibria, reaction stoichiometry and rate, modes of heat, and species transport. (CCM)

Discusses evidence-based decision making; describes techniques to support evidence-based retrieval in the field of medicine which emphasize the retrieval and application of high quality knowledge to solve real-world problems; and considers the transferability of evidence-based information seeking to other fields. (Contains 69 references.) (LRW)

Discusses ways of using six literature books to study mathematics in which students read about mathematics in the context of literature to explore problems embedded in the context of a story. (ASK)

Focuses on the use of different strategies for solving sequences of interrelated problems. Discusses some useful techniques a teacher could employ to design problem chains. (Contains 20 references.) (ASK)

Presents some results of a study on teaching negative numbers. Focuses on the identification of addition and subtraction, the use of the number line, additive problem solving, and the possibility of following several sequences of numerical extensions. Indicates the importance of previous ideas on positive numbers and how these ideas influence the…

Knowledge in academic disciplines is being challenged by the instrumentality of workplace learning. However, the way math is taught in vocational education is often irrelevant or infantilized. To satisfy the need for a creative, problem-solving work force, mathematical disciplinarity is needed. (Contains 68 references.) (SK)

Explains what successful scaffolding requires and discusses three problems that teachers have when using scaffolding. (YDS)
