Infant reaction to adult speech was studied through frame-by-frame analysis of sound films. Infants' actions were found to be synchronized with the organized speech behavior of the adults in his environment. (ST)

Discusses a student project which is intended to teach undergraduates concepts and techniques of nuclear physics, experimental methods used in particle detection, and provide experience in a functioning research environment. Included are detailed procedures for carrying out the project. (CC)

Presents some examples of using college, university, industrial, and governmental raw data to conduct physics classroom experiments and activities. Indicates that the approach has the advantages of making the student work publishable and of motivating the student to improve the quality of lab reports. (CC)

Discusses an experiment on friction to illustrate the "law" governing the relationship of the friction force to the volocity of air track cars. (CC)

System Development Corporation conducted an extensive project of conceptualization and planning of models for compensatory educational intervention for older disadvantaged youth, at the secondary and postsecondary levels. Two intervention strategies were developed, and this report details the development of a field implementation plan for a…

The book is based in part on an unusual kind of social experiment whose main purpose was to see if a diverse group of 19 colleges and universities could be stimulated to undertake changes in their policies and programs that would be designed primarily to improve the educational environment for students. The stimulus for change was comprehensive…

This document presents a series of physics experiments which allow students to determine the value of unknown electrical capacitors. The exercises include both parallel and series connected capacitors. (SL)

The problem of spurious significance in multivariate exploratory research is discussed. When a very large number of statistical tests are performed, many tests will be significant on the basis of chance alone. To counter this problem, the use of two sign tests to analyze sets of results has been suggested; the chance expectation [CE test] assesses…

This experiment investigated the effect of a delay in informative feedback in computer-managed instruction upon later retention. Experimental groups of undergraduate college students were given a computer-managed test and received informative feedback (1) immediately, item by item (2 second delay); (2) following the entire test (20 minute delay);…

Discusses weaknesses in the Burstall report's evaluation of a pilot experiment in elementary-to-secondary French instruction. (AM)

Describes an experiment designed to acquaint the chemistry student with polymerization reactions, vacuum techniques, liquid scintillation counting, gas-liquid chromatography, and the handling of radioactive materials. (MLH)

Describes an experiment in which luminescence is observed during a reaction between sodium borohydride and trisbipyridalruthenium (III). Includes a discussion of the theory of chemiluminescence. (MLH)
