Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

Discussed is some of the confusion encountered in electrochemistry due to misunderstandings of sign conventions and simple mathematical errors. Clarified are issues involving emf series, IUPAC sign conventions, calculation of cell potentials, reference electrodes, the polarity of electrodes in electrochemical devices, and overpotential.

Describes the Packard's Falling Body Apparatus, invented by John C. Packard, which is essentially an inclined plane combined with a simple and elegant method of measuring the relative time of descent of a steel ball. (JRH)

Outlines benefits of integrating optical instruments in computer-based instructional systems in a science classroom including budget, immediacy, pictorial records, and graphic enhancement. Presents examples of investigative activities involving optical instruments and images digitized for computer-based manipulation. (JRH)

Greater access to scientific instrumentation, courses, and supporting materials through the Internet and Integrated Laboratory Network (ILN) has the potential to profoundly change the way in which instrumental sciences are taught. Increased access to instrumentation will provide better opportunities for students to learn and practice instrumental…

Personal responsibility has long been considered an important component in self-directed learning. And yet, a theoretical understanding of personal responsibility that could lead to meaningful instrumentation has eluded the field. The present study considers the merits of the Triangle Model of Responsibility (TMR) (Schlenker, Britt, Pennington,…

Many behavior patterns that impact on physical activity experiences are established in early childhood, therefore it is important that valid, reliable, and feasible measures are constructed to identify children who are not developing appropriate and healthy activity habits. In this study, measures of physical activity derived by accelerometry and…

The National Survey of Academic Research Instruments and Instrumentation Needs is a congressionally mandated program that collects data concerning scientific research instruments and the academic departments and facilities in which they are located. This report analyzes overall instrumentation issues and trends in all the fields covered by the…

This guide defines a methodology for program monitoring and discusses positive results achieved in Pennsylvania by implementing Instrument-based Program Monitoring (IPM) in the field of child day care services. IPM uses checklists or special questionnaires to structure monitoring interviews and site visits. This method differs substantially from…

The author presents a brief statement giving reasons for followup studies of teacher problems and explains the procedure for conducting such studies, the instruments used for data collection, and the estimated costs of a follow-up program. The four reasons cited for investigating teacher problems are: (1) to expose teacher educators to current…

This packet of forms, instruments, and guidelines has been assembled to aid in the determination of the articulation status and needs existing in elementary-junior high school and junior-senior high school programs. The term "articulation" is understood to mean the smooth transition from one grade or subject area into the next with as little…

This technical specialty course is one of thirty-five courses designed for use by two-year postsecondary institutions in five nuclear technician curriculum areas: (1) radiation protection technician, (2) nuclear instrumentation and control technician, (3) nuclear materials processing technician, (4) nuclear quality-assurance/quality-control…

THE TEST OF BASIC INFORMATION (TOBI) IS A 54-ITEM, MULTIPLE-CHOICE PICTURE TEST DEVELOPED TO MEASURE PREACADEMIC, SCHOOL-RELEVANT KNOWLEDGE. IT CAN BE USED TO ASSESS PROGRAM EFFECTIVENESS BY GIVING IT AS A PRE- AND POSTTEST. IT CAN BE ADMINISTERED INDIVIDUALLY, OR TO GROUPS OF UP TO 15 IF THERE IS 1 ADULT FOR 3 OR 4 CHILDREN, AND TAKES FROM 15 TO…

Descriptive information on evaluation instruments for measuring effective health education programs is included in this bibliography. The evaluation instruments are listed in five categories, four of which correspond to the school level for which the instrument has been designed--elementary, junior high, senior high, and college and nonstudent…

Part of a series of materials in the electrical engineering sequence developed under contract with the United States Office of Education, this laboratory manual provides 10 projects dealing with basic electrical instrumentation and measurement that would be appropriate for a first course. Exercises include activities involving (1) voltmeters,…
