The United States Training and Employment Service General Aptitude Test Battery (GATB), first published in 1947, has been included in a continuing program of research to validate the tests against success in many different occupations. The GATB consists of 12 tests which measure nine aptitudes: General Learning Ability; Verbal Aptitude; Numerical…

This comprehensive manual deals with the problems of planning vocational facilities. Volume I provides floor layouts and specialized designs that interpret educational concepts, equipment needs, and services into functional units for architectural adaptation. Additional planning guidelines clarify purchasing policies and procedures, explain the…

Design of laboratory animal facilities must be functional. Accordingly, the designer should be aware of the complex nature of animal research and specifically the type of animal research which will be conducted in a new facility. The building of animal-care facilities in research institutions requires special knowledge in laboratory animal…

An experiment involving two groups of 193 beginning secondary school students of French, German, and Spanish considers the instructional value of the electronic classroom as an alternative to the conventional language laboratory for the presentation of exercise materials. Experimental design hypotheses state that since more practice is possible…

This booklet, one part of the Intermediate Science Curriculum Study (ISCS) Individualized Teacher Preparation modular program materials, is designed to help a teacher organize the science classroom to facilitate individualized work by pupils. Information is organized into five chapters: Organizing for Diversity, Who Does What Where?, The…

Possibilities opened by video in the theory and practice of foreign language teaching are suggested. Among the advantages are: observation of mouth movements is important to articulation; gestures and facial expressions are an important part of communication; and language presented in social contexts can show socio-linguistic conventions.

Describes two computer simulation programs, "Nerve Physiology" and "Frog Heart," as practical alternatives to the use of live animals in class experiments. Discusses the potential of computer simulation as a feasible alternative to experiments with animals in the classroom laboratory. (CW)

Presents a model system designed for the electrophysiological investigation of single unit activity in intact anaesthetized animals. Illustrates how information is coded into action potential patterns by sense organs. Uses the ampullary electroreceptor of the brown bullhead catfish as an example. (Author/CW)

Discussed are field analyses of data involving paleocurrent directions using a goniometer and special programs for a pocket computer. States that on-site evaluation can provide immediate realization and verification of anomalous results. Includes computer programs and directions for building a goniometer. (CW)

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)

Describes the concept of a unified laboratory program in which integrated experiments are brought together from several areas of chemistry. Discusses the design and implementation of the unified laboratory at Willamette University, including lists of laboratory experiments and projects. (TW)

Defines microcomputer-based laboratory (MBL); discusses necessary hardware and software for operation of an MBL; reviews science applications in secondary education and eight steps involved in constructing a four-paddle interface box, the heart of an MBL; and provides information on suppliers of resources for creating an MBL. (MBR)

Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined. What do they contribute to science learning? What can they contribute to science learning? What is the current status of labs in our nation s high schools as a context for learning…

In more than 90 percent of the American colleges the prevailing method of transfer from secondary school is by certification, based on the pupil's record in secondary school. In the large majority of cases a record of graduation from an accredited secondary school is required of every student admitted to college. When it is considered that in…

Describes an intelligent lightbulb, an optelectric feedback circuit which bridges the conceptual gap between manual and all-electric servos. The circuit is simple and easily understood in dc terms. Also describes a device for demonstrating wave motion constructed with plastic soda straws. (Author/SK)
