Presents two methods for solving equations. An asymmetric approach works backward from a number by reversing operations performed on a variable. A symmetric approach views the equation as a scale and performs inverse operations on both sides of the balance to solve for the variable. (MDH)

Discusses the rate of fall of a wooden beam or a chimney by examining the fall of a highway lamp pole when it is sheered off at its base upon impact by a vehicle. Provides the mathematical formulas to explain and an experiment to illustrate the phenomenon. (MDH)

Presents a model that uses online searching to teach critical thinking skills in elementary and secondary education based on Bloom's taxonomy. Three levels of activity are described: analyzing a search statement; defining and clarifying a problem; and focusing an information need. (Contains 13 references.) (LRW)

Explored are the distributions of residual components in two model systems. A system of components with exponentially distributed lifetimes and the two-dimensional "leaf model" in which objects fall on a plane with positions independent and normally distributed are discussed. Included are the definition, application, computations, and theorem. (KR)

Review of research and development on the design of computer-based simulation for diagnostic training highlights the development and evaluation of eight diagnostic training systems that explored the appropriate level of student modeling needed for technology training. Topics addressed include changes in interface design, displays, and system…

This article reports on answers by children (grades 1-9, n=83) to oral and written questions concerning the phase change from liquid to gas. The development of concepts was followed, proceeding from concrete to abstract ideas. Many students were found to experience difficulties in problem solving even though they may have had the necessary level…

The Quality Circle Model of Planning is presented as a program evaluation approach for schools serving students with blindness. The model helps administrators solve problems using creative, innovative approaches; identifies human and monetary resources for successful implementation of the plan; and provides a framework for evaluating the plan's…

The case of a school district refusing to supply an interpreter for an above-average student with a hearing impairment is used as a point of departure for this discussion of a framework for ethical deliberation and the special role-related obligations that help define the ethics of special education. (PB)

Described is research which sought to prove the hypothesis that mental models tend to preserve their autonomy with regard to the originals they are meant to represent. The results of this investigation involving 200 Israeli students are presented. (CW)

Action science is a communication technique that staff developers can use to increase interpersonal competence and problem-solving skills in schools engaged in the process of school transformation. An example of the action science intervention at a Maryland elementary school is presented. (SM)

Describes the interactions and applications of three models of learning: Bloom's taxonomy, the Jungian or Myers-Brigg's Typology, and William Perry's model of attitude toward learning. (PR)

The "iNtegrating Technology for inQuiry" (NTeQ) model provides a framework for creating an environment for students to use computers as tools to build a strong educational background while solving meaningful problems. This article outlines the NTeQ philosophy, describes the design process for lesson plans, and discusses professional development…

Focuses on the responses of elementary school children (N=336) to an "Awareness of Technology Survey" question intended to explore how they would begin the technological problem-solving process. Contains 29 references. (DDR)

Examined the association between social problem-solving deficits and adolescent antisocial behavior within the family context, and estimated genetic and environmental effects as part of the Nonshared Environment in Adolescent Development project. Found genetic influence for antisocial behavior but not for problem solving. (Author/KB)

When working on tasks or projects, teams typically go through four phases: initiation, creation, elaboration, and completion. Each phase is explained, and two examples illustrate how the model is used after an orienteering exercise to help corporate management teams understand their way of functioning and identify strengths and development points.…
