In this activity, students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In Part One, students play the role of molecules in a beam subject to various loading schemes. In Part Two, students break foam insulation blocks by applying…

This paper recounts the story of Elsie Ripley Clapp (1879-1964), an associate of John Dewey and well known in progressive education circles, who became extensively involved in rural education in Kentucky and West Virginia. The first part of the paper gives an overview of Clapp's early life in the New York City area, her educational background, her…

This high school physics computer software resource is a systems and control simulator that covers the topics of electricity, electronics, mechanics, and programming. Circuits can easily be simulated on the screen and electronic and mechanical components can be combined. In addition to those provided in Crocodile Technology, a student can create…

In every ecosystem, organisms rely on each other in unique relationships that ensure each other's survival. In Plant & Animal Interdependency, find out how plants and animals interact, cooperate and compete. All living things have basic needs and depend on other living things to meet those needs. Discover why the constant exchange of nutrients and…

The author plays off the use of acronyms in education in describing the work of the Southeastern Educational Laboratory (SEL). The SEL was one of the regional educational laboratories established by the U. S. Office of Education in the late 60s to assist in the improvement of public education. It served Alabama, Florida and Georgia. The author…

There is a fair amount of research on individual curricular experiments in specific high school courses, but general research on high school curriculum and what the curriculum should be is hard to find and is far out weighed by theory and policy. Most of the theory and policy literature are dominated by discussions of state and national standards.…

Describes the basic spirit and details of a one-semester lab-oriented chemistry course designed within a flexible, self-paced format for elementary education majors. Included are a syllabus and a competency measure. (CC)

Thoughts are presented from two administrators about the procedure they followed and the problems they encountered in implementing an open education program. Advice is given to those who are about to become involved with open education. (Author/DN)

Dissertation on which this article is based is to be published, in a condensed form, as C.I.E. Research Monograph No. 7 by Oxford University Press (India). (VM)

Describes the program in a summer institute for 25 junior high school science teachers. Innovations used in the program included lecture-demonstrations, small group discussions, open-ended laboratories, and viewing physics films. Problems that arose are reviewed. The method of evaluating the teachers is described. (LC)

Translated from the German by W. D. Halls.

Describes an optical cell, suitable for high-pressure studies between at least -130 and +150 degrees Celsius, which may be assembled for about $50. Discusses experimental demonstration of principles involved when using the apparatus, including effects of pressure on coordination of ions in solution and on reaction rates in solution. (JN)

The theme articles present strategies for achieving quality laboratory projects in vocational agriculture. They describe fundamentals of the construction of quality projects and stress the importance of quality instruction. (JOW)

Provides additional information on a demonstration described in the March 1981 issue of "The Physics Teacher" involving free-falling objects using styrofoam cups, rubber bands, and weights. Approaches the subject using free-body diagrams (included) and discusses the mechanism by which the weights are pulled into the cup. (JM)
