The purpose of the present study was to examine and compare the effectiveness of virtual frog dissection using V-Frog[C] and physical frog dissection on learning, retention, and affect. Subjects were secondary students enrolled in year-long life science classes in a suburban high school (N=102). Virtual dissections were done with V-Frog[C], a…

Describes the design and materials for an elementary school science laboratory which can be installed for approximately $3,000. (MLH)

The teaching laboratory in physics departments in colleges and universities is a source of great potential strength in undergraduate education. Recent surveys and conferences, have identified inadequate teaching equipment and laboratory development. This report reviews these problems and offers suggestions for an enhanced federal effort to solve…

Discusses an experiment on friction to illustrate the "law" governing the relationship of the friction force to the volocity of air track cars. (CC)

This document provides abstracts of 116 laboratory experiments/demonstrations currently being utilized in all areas of engineering education at 52 universities across the United States. (SL)

Describes the experimental arrangement for x-ray analysis of samples which involves the following: the radioisotopic x-ray disk source; a student-built fluorescence chamber; the energy dispersive x-ray detector, linear amplifier and bias supply; and a multichannel pulse height analyzer. (GS)

Findings of two recent surveys on safety equipment in laboratory facilities are presented. The first survey was a pilot study of emergency shower and eye wash equipment. This study was followed by a more comprehensive random survey of safety equipment in 2,820 labs. Among other findings, the surveys indicate that many plants are underequipped, or…

This laboratory manual, part of a series of instruction books on basic experimental chemistry, is designed to provide the secondary school students of developing countries in Asia with laboratory experiences that bring out the fundamental concepts and ideas of chemical kinetics. Taking into consideration the possibility of limited facilities of…

This document is a first-person account by the mathematics coordinator at Temple University dealing with the segment of the TTT (Trainers of Teacher Trainers) project held at the Reynolds Elementary School. The stated purpose of this segment was to provide on-the-job experience in the area of elementary school mathematics. The basic program…

A final examination, review questions, and essay topics are provided. (CP)

Describes an apparatus that uses liquified gases to wash solids. Discusses the procedures and processes used to do a wash with liquid sulfur dioxide. (CW)

Describes use of a Fresnel biprism to demonstrate double-slit interference with polarized light. Discusses polarization and phase properties of a randomly polarized gas. (JM)

Describes an experiment in which a microcomputer was programed to function as a transfer function analyzer to investigate the dynamics of stirred vessels. The main objective of the experiment is to illustrate the theory and application of the pulse test (a method of determining the transfer function of a process). (JN)

It is increasingly important for physicians to develop competence in ordering and interpreting laboratory tests. The goals, organization, instructional approaches, and assessment of a course offering systematic instruction in laboratory medicine are described. (Editor/LBH)
