Describes an experiment to provide students with: (1) an introduction to photochemical techniques and theory; (2) an experience with semimicro techniques; (3) an application of carbon-14 nuclear magnetic resonance; and (4) a laboratory with some qualities of a genuine experiment. These criteria are met in the photooxidation of 9,…

Uses the subject of enzymes to illustrate the topical approach to teaching biochemistry at the secondary level. Includes the procedures for three experiments dealing with various aspects of enzymes. (JN)

Reviews the group supervision literature in counselor training from 1960 to 1983. Included only those articles pertaining to supervised groups of counselor trainees participating in individual counseling practica. Descriptions of group supervision include elements of case presentation, didactic information, and interpersonal process. (Author/BH)

An experiment which measures the steady-state fluorescence of pyrene (the donor) in the presence of varying concentrations of acridine orange (the acceptor) in ethyline glycol solutions is described. Background information, equipment needed, and procedures used are included. (JN)

Describes a system (Apple II microcomputer interfaced to flexible, custom-designed digital hardware) which can provide: (1) Fast Fourier Transform (FFT) computation on real-time data with a video display of spectrum; (2) frequency synthesis experiments using the inverse FFT; and (3) real-time digital filtering experiments. (JN)

This paper describes the design and construction of a local network of microcomputers at the Electrical Computer Engineering Department at Florida Institute of Technology. The design criteria for such a network and the possible applications are discussed. (JN)

Discusses the rationale for and development of an experiment on the oxidation of secondary alcohols with common hypochlorite bleach. The experiment provides a safe, environmentally sound, and inexpensive modern synthetic method. In addition, it utilizes a variety of laboratory techniques and some fundamental oxidation-reduction chemistry. (JN)

Background information, materials needed, procedures used, and typical results obtained, are provided for an experiment on iron-sulfur-carbonyl and -nitrosyl complexes. The experiment involved (1) use of inert atmospheric techniques and thin-layer and flexible-column chromatography and (2) interpretation of infrared, hydrogen and carbon-13 nuclear…

Background information and procedures are provided for an optics experiment related to diffraction order asymmetry. (JN)

Describes the use of soap opera in a language laboratory. Each soap opera episode incorporates a vocabulary list from the course text. The list is supplemented by translation exercises and by a discussion of the particular grammatical principles involved, and the episode is followed by a listening comprehension test. (SED)

Discusses major uses of rats as experimental animals for studying health concerns, pointing out that their size, gestation, and histocompatibility make them useful in various studies. Topic areas addressed include aging, autoimmune disease, genetics, cancer, diabetes, hypertension, infection, reproduction, and behavior. (DH)

Describes a computer communication course (and its associated laboratory) developed for electrical engineering students at the University of Florida. The course teaches seniors and graduate students the theoretical limits that affect the implementation of serial digital communications and surveys the interface standards, data link protocols, and…

Traces the history of the antivivisection movement, examining issues related to the use of animals in studying the cause of rabies. Also discusses issues related to the current controversy over animal experimentation. (JN)

Four questions chemistry teachers should regularly ask are How well informed am I on safety? Do I instruct students about safety in an appropriate manner? How well do I plan for safety? Do I accept my responsibility to supervise personally all laboratory activities? Answers to these questions are provided. (JN)
