This study purposed to develop a means of evaluating student performance in auditions for festival bands which would minimize the inconsistencies of subjective judgment. Tape recordings of student auditions were played three times to judges. During the first audition, evaluators rated students on a continuum scale with numerical divisions, and…

The Classroom Communicator, an experimental machine built at Pennsylvania State College, is both a research and a mass teaching aid device. It will record and measure reactions of individuals in an audience, almost instantaneously, and will help improve the rate and effectiveness of learning. This report shows in detail that, to a large extent,…

The purpose of this study was to investigate a test procedure to determine auto mechanic know-how. Participants were allowed to look at, feel, and smell a number of defective vehicle parts in order to identify the part, indicate its condition, decide why it failed, and decide on whether to reuse it or not. The test was divided into 10 categories…

On the basis of an established need, the Occupational Values Inventory (OVI) was developed as one of the data collection instruments for the Vocational Development Study to measure the occupational values held by ninth graders, including: (1) Interest and Satisfaction, (2) Advancement , (3) Salary, (4) Prestige, (5) Personal Goal, (6) Preparation…

Announces the incorporation of a laboratory information management system (LIMS) into the academic environment. Describes the applications of a computer-automated laboratory system at one university. Stresses the benefits to students of the use of such a system in terms of entry into the industrial environment and to professors in grading. (CW)

Describes an experimental setup using a microcomputer for demonstrating the circadian movement of petioles. Discusses experiments that were performed using this apparatus and factors that relate to these plant movements. Includes graphs that have been obtained. (CW)

Describes an experiential lab program for a two-year college's chemical technology program. Discusses student experiences in six miniature pilot plants that represent the essential instrumentation and chemical processes found in the chemical industry. Recognizes the industries that helped implement the program. (TW)

Describes a system of interfacing allowing a range of signal conditioning and control modules to be connected to microcomputers, enabling execution of such experiments as: examining rate of cooling; control by light-activated switch; pH measurements; control frequency of signal generators; and making automated measurements of frequency response of…

Describes an interface designed to meet the requirements of an instrumentation teaching laboratory, particularly to develop computer-controlled digital circuitry while exploiting electrical drive properties of common transistor-transistor logic (TTL) devices, minimizing cost/number of components. Discusses decoding for Pet, switches, lights, and…

Reports on the U.S. Air Force method of training biomedical equipment technicians. The 50 self-paced modules that make up the course are randomly sequenced to reduce capital investment in training equipment. Other useful bits of information from the military are included in this article. (Editor/HD)

Describes a laboratory technique for use in an undergraduate instrumental analysis course that, using the interpretation of window diagrams, prepares a mixed liquid phase column for gas-liquid chromatography. A detailed procedure is provided. (BT)

Divides musical composition selection for student orchestras into two categories, teaching repertoire and concert repertoire. Provides a number of helpful hints and criteria for selecting both. Includes "Ten Terrific Titles,""Super String Selections," a list of premiere selections for grades two through six, and a list of selected resources. (MJP)

Included are 30 science activities that include computer monitoring, fieldwork, enzyme activity, pH, drugs, calorimeters, Raoult's Law, food content, solubility, electrochemistry, titration, physical properties of materials, gel filtration, energy, concepts in physics, and electricity. (KR)

Four microcomputer applications are presented including: "Computer Simulated Process of 'Lead Optimization': A Student-Interactive Program,""A PROLOG Program for the Generation of Molecular Formulas,""Determination of Inflection Points from Experimental Data," and "LAOCOON PC: NMR Simulation on a Personal Computer." Software, availability,…

Discussed is the integration of microcomputers into the science laboratory curriculum. The approach provides an exposure to important aspects of computer technology while preserving concrete experiences provided by hands-on laboratories. (CW)
