Describes an experiment to give students exposure to digital control widely used in industry but not given much attention in most undergraduate process control curricula. Students write their own control programs and experimentally determine the transfer functions for all system components. Also describes experimental apparatus used in the…

Unfilled engineering faculty positions and obsolete laboratory equipment continue to threaten the quality of U.S. engineering education, but improvements are being made, according to a progress report issued as a followup to the National Engineering Action Conference held in April (1982). Highlights on the report are provided. (Author/JN)

Presents a technique to produce samples for x-ray diffraction studies on the Tel-X-Ometer 80 x-ray apparatus from readily available crystalline powders and discusses observations of transverse modes of an optical resonator. (SK)

Two computer-oriented chemistry laboratory simulations are described. The material focuses on acid-base titration and an ideal gas simulation. (MP)

Reviews the historical development of thermometry and the origins of the Fahrenheit and Celsius temberature scales. (CS)

A study was conducted to determine the extent to which departments of industrial education are offering courses which assist students in becoming technologically literate. Two types of classes are being offered: (1) technology as a discipline and (2) the tools, materials, and processes of industry, but general courses were not widely available.…

Describes a portable fluid power engineering laboratory and class demonstration apparatus designed to enable students to design, build, and test multi-actuator circuits. Features a variety of standard pneumatic values and actuators fitted with quick disconnect couplings. Discusses sequencing circuit boards, microcomputer control, cost, and…

Describes the impact on chemistry laboratories and teachers in the United Kingdom of the Packaging and Labelling of Dangerous Substances Regulations 1978. These regulations require suppliers to label containers in particular ways. (HM)

A classroom technique for projecting microorganisms on a TV screen is described. Instructions are given with a step-by-step approach and effective subject matter is suggested. (SA)

Describes techniques for making laboratory glassware from discarded bottles, fluorescent tubes, and light bulbs. All materials needed are constructed from commonly available household items. (SL)

Faculty members at Temple University listed proposed student and faculty functions desirable for a new language laboratory; this article describes the Media Learning Center which resulted. The Center contains an audiotape theater, slide and filmstrip theater, videotape and multi-media theaters and resources library. Audiovisual equipment in each…

Presents an activity that focuses on insects and the choices they make in response to sensory input. Involves students and teachers in inquiry-oriented investigations and presents details of preparation, a discussion of the teacher's role, and a materials list. (DDR)

Discusses modular technology labs and their effect on education. Describes modules offered by CHEC Systems (Consumer and Home Economics); Paxton/Patterson; Marcraft; Lab-Volt; Synergistic Systems/Pitsco; as well as some that were created from the ground up by teachers. (JOW)
