Discusses how chemists describe an amount of material and provides a visual representation for the solution of typical stoichiometry problems. (YDS)

Describes a decision-making process that guarantees continuing success for college facility management in discovering effective solutions that are process-focused, data-driven, and results-oriented. (GR)

Design research is a valuable tool to help the designer understand the problem that he/she needs to solve. The purpose of design research is to help state or understand the problems better, which will lead to better solutions. Observational research is a design research method for helping the designer understand and define the problem.…

The equation of motion for a mass that moves under the influence of a central, inverse-square force is formulated and solved as a problem in complex variables. To find the solution, the constancy of angular momentum is first established using complex variables. Next, the complex position coordinate and complex velocity of the particle are assumed…

The preproblem pondering strategy of "anticipate the answer" involves attempts to anticipate the form of the answer and the answer's relationship to the conditions of the problem. It draws on the skills of recognition, identification, interpretation and builds confidence.

A mathematical problem is solved using the extension-reduction or build it up-tear it down tactic. This technique is implemented in reviving students' earlier knowledge to enable them to apply this knowledge to solving new problems.

Pick's theorem can be used in various ways just like a lemon. This theorem generally finds its way in the syllabus approximately at the middle school level and in fact at times students have even calculated the area of a state considering its outline with the help of the above theorem.

The heliocentric, or Sun-centered model, one of the most important revolutions in scientific thinking, allowed Nicholas Copernicus to calculate the periods, relative distances, and approximate orbital shapes of all the known planets, thereby paving the way for Kepler's laws and Newton's formation of gravitation. Recreating Copernicus's…

Prediction is a great skill to have in any walk of life: it can, in fact, save lives at times. While the two investigations posed in this column may not be that dramatic, they might just increase one's appreciation of some important connections between grids and rectangles and the divisors of numbers that appear in the dimensions of those…

This exploratory study used structured tasks as direct measures of approaches to learning to examine a potentially important domain of school readiness that is comprised of the multiple ways children engage in learning situations. A structured task designed to measure problem-solving flexibility was found to relate to a subset of a teacher rating…

The present research examined the processes of schema formation in problem solving. In 4 experiments, participants experienced a series of tasks analogous to A. S. Luchins' (1942) water jar problems before attempting to solve isomorphic target problems. Juxtaposing illustrative source instances varying in procedural features along multiple…

This article focuses on the research program on mathematical problem solving conducted by the Center on Accelerating Student Learning (CASL). First, a subset of CASL themes, illustrated in the mathematical problem-solving studies, is highlighted. Then, the theoretical underpinnings of the mathematical problem-solving intervention methods are…

The breadth and heuristic merits of Harold (Buddy) Goodall's scholarship exemplify the teachings and influence of Gerald Phillips. One nominator applauds Goodall's leadership and dedication to furthering the visibility and utility of applied communication. Goodall's research is also widely used in other fields such as sociology and anthropology,…

In project-based learning, students work in groups to solve challenging problems. They decide on an approach and what activities to pursue. Their teachers guide and advise them rather than direct the work. The process that students use is to gather information from many sources, analyze the value of what they find, and derive knowledge from it.…

This paper reports the coping strategies characterising self-professed weak copers. In order to do so it examines strategies reported by a subset of a sample of 976 adolescents, as measured by the Adolescent Coping Scale. What is of interest in this investigation are the coping strategies of the most vulnerable adolescent group. Such information…
