Reported is a study related to a Project on an Information Memory Model in which the performance of children living in two different cultures (Libyan and American) was compared on two problem solving tasks to investigate cultural differences in memory information processing. One task was the chemical bodies experiment studied by Piaget and…

Discusses the use, types, and advantages of simulation activities in problem-solving instruction. Reviews a research study of simulation in medical education. (MLH)

Describes a concentrated course of one week duration in elementary computer physics. The purpose of it is to introduce computer physics and to show how to remove the traditional constraints on physics courses, and to gain insight into the solutions of complex problems using the computer. (GA)

Presents a method for simplifying calculations in quantum chemistry by calculating molecular energy from the electrostatic theorem. (SL)

Describes chemistry games included in the PLATO computer-generated graphics system developed at the University of Illinois to give students problem solving practice. (SL)

Presents part seven of a continuing presentation of exponential functions. Provided is an extension of the part six discussion, exponential population growth, to world population growth. (SL)

Presents an operator which transforms quantum functions to solve problems of the stationary state wave functions for a particle and the motion and spreading of a Gaussian wave packet in uniform gravitational fields. (SL)

Presents a completely arithmetic development of Newtonian dynamics in which all classical conservation laws are valid and all equations are in forms amenable to high-speed digital computer computation. (SL)

Provides an introduction to Debye potentials and simplified derivations of the multipole expansions of electrodynamic fields. (SL)

Questions Piagetian theory that dismisses the idea of accelerating cognitive development through classroom activities. (CP)

Advances the thesis that philosophical questioning should precede or accompany children's participation in science activities in the elementary grades. (CP)

Investigated were relationships between student self perception and actual classroom behavior in problem solving situations of 201 elementary students. Results indicated students with positive self concept were more independent from teachers and peers. Dependance upon others by low self esteem students is more evident in higher grades. (SL)

Examines the utility of the ancient Chinese concept of Tai-chi as a model for interpreting complex contemporary issues in science education. Describes the model and suggests how it can be useful in understanding scientific phenomena and in guiding instruction. (ML)

Explains an algorithm which details procedures for solving a broad class of genetics problems common to pre-college biology. Several flow charts (developed from the algorithm) are given with sample questions and suggestions for student use. Conclusions are based on the authors' research (which includes student interviews and textbook analyses).…

Good problem solvers and poor problem solvers in advanced physics (N=8) were significantly different in their ability in translating, planning, and physical reasoning, as well as in problem solving time; no differences in reliance on algebraic solutions and checking problems were noted. Implications for physics teaching are discussed. (DH)
