Describes a simple method for determining self-inductance of non-ferromagnetic rings. Suggests fitting the ring with an auxiliary coil and using a solenoid driven with a known frequency alternating current. Amplitude change and phase shift can be measured and used to calculate inductance. Material list, calculations, and sample results are given.…

Describes an experiment, designed for use in the undergraduate laboratory, that measures the bond energies of molecules using a small commercial mass spectrometer and low-cost digital voltmeters. (BT)

This paper discusses several considerations and techniques in doing research which attempts to measure the effects of visual images on viewers. For example, to describe precisely the effects of some element of a visual image or series of images, researchers must be able to specify the institutional context in which the image is presented and…

Contends that the nature of physics has been misrepresented by blurring or ignoring important distinctions between "errors" and "discrepancies" and that dealing with these and related problems can improve students' enjoyment of labs and understanding of physics. Nature of physics, role of experiments, experimental errors, and error analysis are…

This document contains three learning activity packets (LAPs) that outline the study activities for the instructional area of measuring for an Auto Mechanics I course. The three LAPs cover the following topics: rules, the outside micrometer, and the inside micrometer. Each LAP contains a cover sheet that describes its purpose, an introduction, and…

This book of tests is designed to assess the competencies of the Child Development Associate (CDA) trainee: both what the trainee knows and how well the trainee works with children. The tests are designed as posttests to be administered after the trainee's completion of the relevant learning module. Each test consists of multiple choice questions,…

AN EMERGING METHODOLOGY OF PROGRAMING AVOIDS SOME OF THE UNFORTUNATE EFFECTS ON PROGRAMER BEHAVIOR PRODUCED BY INTERPRETATIONS OF TWO EARLIER METHODOLOGIES. WHILE SKINNERIAN PROGRAMING OFTEN HAS LED TO TRIVIAL PROGRAMS THROUGH PROBLEMS OF APPLICATION OF THE CRITERIA OF SPECIFIED BEHAVIORAL OBJECTIVES AND LOW ERROR RATES, CROWDERIAN PROGRAMING HAS…

Twelve PLATO lessons are reproduced in this document to show the status of computer guided experimentation (CGE) instructional programs. The lesson topics include a description of the CGE-PLATO instructional laboratory, an introduction to CGE-PLATO tests and special software routines, router lesson for two electrical engineering courses, and an…

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…

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)

Profiles a class exercise that teaches the importance of developing an accurate definition of a psychological construct (guilt, control, altruism). The more precise the definition, the easier it is to choose an appropriate technique to measure that construct. Discusses the Health and Psychosocial Instrument File, a recent measurement database.…

The evolution of the two-stage cluster sampling plan is described, as are the instruments used to collect survey data from principals, teachers, specialists, and parents. Particular attention is given to the Classroom Activities Log, a unique teacher-completed instrument which provides a complete description of daily student experiences.…

This running commentary cites examples to show that measurement and research in education, since Binet, have been used to solve school problems. Current problems cited stem from post-World War II acceptance of the goal of educating "all the children of all the people." Compensatory education, peer-tutoring vs. competitive scrambling, mastery…

This document contains eight learning activity packets (LAPs) for the "basic and related technology" instructional area of a Machine Shop I course. The eight LAPs cover the following topics: basic mathematics, blueprints, rules, micrometer measuring tools, Vernier measuring tools, dial indicators, gaging and inspection tools, and…

This paper discusses some of the problems involved in the testing of minority group children, focusing on the testing of bilingual minorities and emphasizing the special problems involved in testing Hispanic children. Considered are a variety of ways in which tests have been misused and misinterpreted in working with these children. It is…
