This publication is written for those researchers who are interested in the use of radionuclides and radiation in the animal science field. Part I presents topics intended to provide the theoretical base of radionuclides which is important in order to design an experiment for drawing maximum information from it. The topics included in this…

An educational survey of British language teachers concerning the use of the language laboratory focuses primarily on function, facilities, and performance specifications. Read in conjunction with two other reports published by the Ministry of Technology, this study is meant to help teachers, architects, and administrators develop language…

This volume is one of the series for the Chemical Technician Curriculum Project (ChemTeC) of the American Chemical Society funded by the National Science Foundation. It consists of discussions, exercises, and experiments on the following topics: the nature of reversible processes, equilibrium constants, variable reaction tendencies, practical…

This volume is one of a series for the Chemical Technician Curriculum Project (ChemTeC) of the American Chemical Society funded by the National Science Foundation.

THIS RESEARCH ATTEMPTED TO DEMONSTRATE THE FEASIBILITY OF DEVELOPING TEST INSTRUMENTS TO DETECT HOW LIMITED VARIABLES IN EDUCATIONAL EXPERIENCES AFFECT STUDENT BEHAVIORAL DEVELOPMENT. THE EXPERIMENTAL HYPOTHESES DEVELOPED FOR THE STUDY WERE CONCERNED WITH IDENTIFYING AND DEFINING INDIVIDUAL ABILITIES OPERATING IN THE REALM OF SCIENCE EDUCATION.…

IN-ED is a monthly publication devoted to innovative educational ideas in higher education. In this issue, the facilities and equipment used in a completely self-paced life science laboratory at the University of Texas of the Permian Basin are described. Also discussed are the instructional methods used. (MH)

Designed to assist the teacher in introducing a unit on research and experimentation into his/her industrial arts program, this manual provides information for adoption to both classroom instruction and laboratory activities, and a student workbook. The instructor's section includes (1) What is Research? (2) Importance of Research and…

The expense of a dial access information retrieval system (DIARS) is weighed against its benefits. Problems of usage and efficacy for the student are outlined. A fully automated system is proposed instead, and its cost-saving features are pointed out. (MS)

Describes an advanced analytical chemistry laboratory experiment developed for the determination of the performance parameters of a spectrophotometer. Among the parameters are the baseline linearity with wavelength, wavelength accuracy and respectability, stray light, noise level and pen response time. (HM)

Brief suggestions for laboratory and classroom instruction in various chemistry topics are provided. (CP)

Reviews a cooperative program in which a number of nearby chemistry departments combined to purchase a mobile spectroscopy laboratory housed in a step-van truck. (SL)

Precautions to be used with the handling of corrosive gases, liquids and solids are listed. Storage suggestions for the materials are provided. (CP)

Information from a variety of sources on laboratory safety is pooled to propose a universal code. Along with caution, warning, and danger labels, a required use category is suggested. (CP)

Techniques used to evaluate a laboratory course are outlined. Course organization is described briefly, followed by details of the methods of collecting information and the method of sampling the groups of students. Methods include questionnaire, informal interview, group interview, free response, and observation. (LBH)

The inability of foreign language students to produce acceptable approximations of new vowel sounds initiated a study to devise a real-time visual display system whereby the students could match vowel production to a visual pedagogical model. The system used amateur radio equipment and a standard oscilloscope. (CHK)
