Israeli junior high-school science teachers usually have a background in biology, and their knowledge of physics is limited. We show that by improving teachers' "qualitative understanding" it is possible to increase their confidence and willingness to teach physics. We conducted three-day workshops for teachers (n = 92), which were…

A theoretical model specifying the underlying knowledge and procedures whereby human subjects can generate effective initial descriptions of scientific problems was formulated. The model is prescriptive since it does not necessarily try to simulate the behavior of actual experts nor assume that their performance is optimal. The model, elaborated…

This document consists of four units. The first of these views calculus applications to work, area, and distance problems. It is designed to help students gain experience in: 1) computing limits of Riemann sums; 2) computing definite integrals; and 3) solving elementary area, distance, and work problems by integration. The second module views…

This paper describes a model for the adolescent's understanding of the motion of objects, and the application of this model to the design of beginning physics instruction in mechanics. Students' difficulties in learning classical Newtonian mechanics are described and integrated into current cognitive science research. Research findings on physics…

The use of computer spreadsheet programs in the physics laboratory is discussed. An example of this application with a conservation of energy laboratory is presented including the cases of a rolling sphere and a sliding sphere. (CW)

Examines the relationship of the amount of available short-term memory with the complexity of tasks the subjects mastered. Presents some hints for a better design of instruction. (YP)

Describes the nature of cognitive research. Misconceptions research in mechanics and electricity are reviewed. Research results on expert/novice differences in knowledge organization and problem solving are reviewed. Implications for classroom teaching are discussed. Lists 34 references. (YP)

Develops an experimental teaching method emphasizing the nature of functions including graphical representation in an introductory college physics course (mechanics). Examines the effects of this method on student's problem solving and attitude toward physics. (YP)

Illustrates how the details of a real-life traffic accident may be analyzed with simple physics to prove that evidence can be enough to convict a motorist of a serious offense. (DDR)

In this paper, we take a look at two electrostatics problems concerning hemispheres. The first problem concerns the direction of the electric field on the flat cap of a uniformly charged hemisphere. We show that the symmetry and principle of superposition coupled with Gauss's law gives a delightfully simple solution and then go on to examine how…

This instructional guide, one of a series developed by the Technical Education Advancement Modules (TEAM) project, is a 20-hour introduction to industrial physics that explains and demonstrates to industrial maintenance mechanics the direct relationship of physics to machinery. Project TEAM is intended to upgrade basic technical competencies of…

This paper reviews and critiques the existing research on a widely recommended instructional approach called context-based physics, which involves placing physics material within a real-life context in an attempt to improve student motivation, problem solving, and achievement. Described first are the problems that exist with traditional physics…

In this paper, we explore the use of isomorphic problem pairs (IPPs) to assess introductory physics students' ability to solve and successfully transfer problem-solving knowledge from one context to another in mechanics. We call the paired problems "isomorphic" because they require the same physics principle to solve them. We analyze written…

The universities and faculties which educate teachers of mathematics for teaching pupils/students of any age group from pre-school age to higher education carefully monitor and compare valuable results of this research, detect the areas in which the mathematical achievements of pupils should be improved at the national level and propose the ways…

The primary task in solving a physics problem is to select ways of viewing the problem in terms of physical systems whose behavior is described by physical laws. The physical systems are, in general, only approximate models of the real-world systems. As models of real-world systems are made more accurate, the equations involved quickly become…
