Explores strategies in the situation of a runner trying to evade a tackler on a football field. Enables the student to test intuitive strategies in a familiar situation using simple graphical and numerical methods or direct experimentation. (JRH)

Presents an application of fundamental principles of mechanics for an isolated system in solving problems related to rocket velocity and exhaust elements. (JRH)

Describes a program to encourage students in grades one through three to draw illustrations for word problems and then use the pictures to help solve the problems. (MKR)

Describes the incorporation of audio-taped notes about student work, a rubric for scoring aspects of students' problem solving, and student portfolios in a program of classroom assessment. (MKR)

This column discusses five children's books selected to develop math concepts involving problem solving, reasoning, and communication. The books are "Only One" (Marc Harshman); "The Librarian Who Measured the Earth" (Kathryn Lasky); "Counting Jennie" (Helena C. Pittman); "The Search for Delicious" (Natalie Babbitt); and "The Toothpaste…

A mechanism for using personal computer spreadsheet software to generate unique laboratory and problem assignments in optics for each student and provide corresponding solutions that can be checked quickly is described. The method minimizes some students' tendency to inspect others' solutions without solving problems themselves. Another…

Presents a review exercise requiring students to sort diagrams and descriptions of price elasticity of demand. Reports that students are given jumbled diagrams and explanations that they must arrange in proper form. Reveals that some items are designed as distractors. (SG)

Explains the concept of environmental auditing as analogous to financial auditing, as manifested through the six guiding principles of environmental excellence, and as utilized by industrial and commercial interests. Presents a questionnaire-based method to introduce students to the techniques involved in environmental auditing. (seven references)…

A real problem from the everyday world is presented. Students are asked to estimate the distance between two planes using a photograph taken by a passenger on one of the planes. The process used to solve the problem and possible errors encountered are discussed. (KR)

Suggestions are offered for resolving conflicts between parents of gifted students and educators. Specific guidelines are offered for both parents and educators to facilitate an effective conference. Additional guidelines consider conflict styles, problem solving, and the "caring confrontation" technique. (DB)

A real world sample of actual data that students can use to see the application of the Hardy-Weinberg law to a real population is provided. The directions for using a six-step algorithmic procedure to determine Hardy-Weinberg percentages on the data given are described. (KR)

Described is how the crumpling of paper balls exhibits the concept of a topological dimension similar to fractals. The mass of the crumpled paper ball is found to be proportional to its diameter raised to a nonintegral power. (KR)

An exercise which relates particle scattering and the calculation of cross-sections to answer the following question--"Do you get wetter by walking or running through the rain?"--is described. The calculations used to answer the question are provided. (KR)

From a survey of 1,000 high school students, the following science anxieties were found: (1) danger anxiety, (2) test anxiety, (3) math and problem-solving anxiety, (4) squeamish anxiety, (5) performance anxiety, and (6) classroom anxiety. (PR)

Presents an educational game on probability that can be the starting point for an open-ended statistical project. (ASK)
