Discusses the feasibility of using fermenters in secondary school laboratories. Includes discussions of equipment, safety, and computer interfacing. Describes how a simple fermenter could be used to simulate large-scale processes. Concludes that, although teachers and technicians will require additional training, the prospects for biotechnology in…

This paper describes an attempt to facilitate students' learning of scientific concepts by using detectors that take as input physical information and output an instantiation of the concept. The principle hypothesis was that students would have a better understanding of the concept of image if they were taught to use a simplified, runnable model…

Describes the function of the various parts of the microscope and their integration in the formation of an optical image. Presents a procedure for setting up a microscope to obtain maximum resolution and contrast for each objective lens at all magnifications. (JRH)

Described is an exercise which examines the effect of reading aloud a technical passage of science material while the heart is monitored by a computer. The experimental setup, design, and data analysis are discussed. (CW)

Provides ideas for using the same port connection of personal computers to interface with laboratory instruments. Contains specific instructions on how to build transducers. Includes plans and diagrams for thermistors and light meters as well as computer programs for displaying instrument readings on monitors. (TW)

Describes a chemistry lab experiment in which a microcomputer is used to graph data. In the experiment a catalyst is used to decompose a commercial bleach. The computer's game port is used with a potentiometer to plot the volume of oxygen gas produced versus elapsed time. Courseware information is included. (TW)

Presented are 29 science activities for secondary school science instruction. Topic areas include botany, genetics, biochemistry, anatomy, entomology, molecular structure, spreadsheets, chemistry, mechanics, astronomy, relativity, aeronautics, instrumentation, electrostatics, quantum mechanics, and laboratory interfacing. (CW)

Discusses the use of microcomputers as a universal instrument to replace more expensive instrumentation in many traditional labs. Describes the availability of microcomputers as inexpensive educational tools which can be used successfully in labs with minimal requirements on the computer. (SK)

Describes the functioning of temperature transducers, or thermistors. Discusses the interface connections between thermistors and the game-port of several kinds of microcomputers. Demonstrates how to construct a thermistor probe and suggests several applications of the use of such probes in various scientific experiments. (TW)

This guide offers information and procedures necessary to train electronics engineering technicians. Discussed first are the rationale and objectives of the curriculum. The occupational field of electronics engineering technology is described. Next, a curriculum model is set forth that contains information on the standard electronics engineering…
