Discusses a case study of a project created for the U.S. Air Force, Air Combat Command, in which mental models were taught, reinforced, and assessed as the foundation for instruction. Preliminary data for 183 students reflected a 93% mastery level and a 79% cumulative gain in students' ability to troubleshoot difficult problems. (Author/AEF)

Describes problems that are presented in the form of experiments. The philosophy, method of solution, and several examples of mechanics experiment problems are described. (LZ)

Describes three approaches teachers can use to help students understand multiplication and division: calculator explorations, problem solving, and discussion topics. Specific examples are provided for primary and upper grades. (MDM)

Based on the author's experiences, this article presents approaches to aid in developing interactive presentations. Galaxy and funnel methods offer more room for creativity when compared to metaphors such as step, line, and road models. Highlights include diagrams, personal narratives of advantages, disadvantages, and steps taken in creating an…

Describes the graphing calculator as a new graphical approach to standard physics problems. Presents a collision problem to illustrate its use. (JRH)

This article describes leadership development activities with gifted preschool and kindergarten children enrolled in the University of Redlands (California) summer school program and a local private elementary school. Methods of teaching the skills of social sensitivity, problem solving, and conflict resolution are described, including role…

Discusses the problem-solving heuristics of examining for special cases, utilizing dimensions to make sense of proposed solutions, and symmetry. Presents examples to illustrate the use of one or combinations of these heuristics. (MDH)

Suggests that teachers should consider which questions to ask as a part of instructional preparation. To ensure that diversity and critical thinking are involved, a teacher should use a taxonomy for a template when writing questions. Presents and discusses Bloom's taxonomy, Gagne's levels of learning, and a taxonomy for general science process…

An exercise that gives students a chance to use the equations of state for both an ideal gas and for an adiabatic process in determining the points at which heat flow reverses direction and at which the working substance reaches its maximum temperature is demonstrated. (KR)

This excerpt from "A New View: Economics and the Zoo," by Diane J. Coleman and Joyce R. Monger, gives teaching suggestions for teaching economic concepts using the zoo as a case study. It gives texts of three readings for students on the purposes of zoos, evaluating a zoo's accomplishments, and economic decision making through analysis of typical…

Analyzes talk to discover what teacher verbal behaviors are associated with critical thinking and problem-solving behavior in children. Finds that teacher questioning and structuring in role enhanced the amount of children's evaluative and divergent thinking most. Offers an analytical comparison of two lessons to demonstrate teaching strategies.…

This article suggests ways in which special educators of students with emotional and behavioral disorders can introduce puppets into their classrooms as educational and therapeutic instruments. Puppets are able to help students identify problems and find rational solutions in a nonthreatening situation. Two sample applications are included. (DB)

This article presents a graduated word problem sequence in mathematics, beginning with simple words; progressing to phrases, sentences, and paragraphs; advancing to paragraph word problems with extraneous information; and finally having students create their own word problems. Results from 67 elementary students with learning disabilities support…

A method for demonstrating eutrophication that can be used as a simple illustration of the phenomenon or as a basis for problem-solving activities is presented. A sample worksheet with procedures for this activity and discussion questions is included. (Author/KR)

The data from measurements of the density of tungsten, steel, aluminum, and PVC spheres are used to extrapolate the infinite density of something such as a neutron star. An apparatus that allows for precision measurements is described. A discussion on error analysis is appended. (KR)
