Describes the necking of polymer sheets that occurs when they are stretched. Discusses the effect and the mechanisms of necking. Lists four references. (YP)

Describes experiments used during recent history to explain the nature of the quantum world. Explains the essential elements of experiments using polarized light and magnetic flux. Illustrates differences between classical theories in physics and quantum theory. Shows how experiments in the microscopic and macroscopic world appear to support…

Research indicates that the educational effectiveness of Microcomputer-Based Laboratories (MBL) may be due to the real time nature of the experience. This article describes a study where kinesthetic feedback was completely removed by giving students only visual replications of a motion situation. If simultaneity of perception is the important…

This study compared the effects of cooperative learning groups to traditional instruction in remediating students' misconceptions about temperature. Students from grades 3, 4, and 5 in two rural elementary schools participated in the study. Students completed a pretest, a cognitive conflict laboratory activity and a posttest that measured…

This conference on physics education was held to improve cooperative efforts in connection with 12 topics previously identified by a survey. A working group was organized in association with each of these topics with the hope of creating or reinforcing a network. Working groups included: network development procedures; graduate education and…
