Describes the use of cassette tape recordings in preparing freshman chemistry students for experiments in laboratories. The tapes are said to have decreased student anxiety in the laboratory and increased laboratory skills. (SA)

Describes how to measure Brewster's angle using Polaroid sunglasses and the reflection of the ceiling light on a polished floor. (GA)

In this experiment, the student duplicates the experiment reported by Wohler in 1828. (BB)

In this experiment, benzylic hydrogen reactivity is used to prepare dimers of a variety of alkyl benzenes, and the benzylic hydrogen reactivity of these compounds are compared. (BB)

This simple two-phase procedure for the oxidation of secondary alcohols to ketones is applicable to a wide variety of substrates and is also ideally suited for the undergraduate laboratory. (BB)

Describes a titration procedure done in glacial acetic acid. (BB)

Describes a college level introductory oceanography course that incorporates a hands-on laboratory component. The activities include the determination of density and buoyancy, light transmission in sea water, and wave refraction. (MA)

Diagrams and explains construction of an actograph which quantitatively records daily movements of animals for a 24-hour period. Combines use of a kymograph and the teetering box of Palmer. Biorhythm activities with fiddler crabs, cockroaches, and hamsters are suggested. (CS)

A mathematics laboratory approach used with hearing-impaired junior high youngsters is described and discussed. (DT)

Preliminary evaluations of the University of Florida's pharmacy practicum-internship program cover: (1) the interns' subjective evaluations of their experiences; (2) the preceptor's subjective evaluation of interns' performance over two years; and (3) objective measurements of student competencies. (LBH)

Reports on a Listen-Read Program exposing children to a variety of language in sound and print through the coordinated use of books and listening centers; a study of the program indicated higher scores on a standardized reading test resulted from children's listening to the text while they read. (HOD)

Listening comprehension exercises in second language instruction are expected to: (1) increase students' efficiency at message extraction, and (2) lead to assimilation of new vocabulary and expressions. Data from a small experiment using such exercises illustrate the distinctions drawn and the limitations. (CHK)

Presents short articles on: display of line spectra, calorimeters, filling balloons from gas jets, and digital mini-module systems. (MLH)

Directions are given for an activity in which students are introduced to infinite geometric series. (DT)

After summarizing the findings of laboratory experimental geropsychological research pertinent to the instruction of older adults, this review focused on delineating the explicit implications of the research for adult education. Thirty-six implications were culled from the literature and categorized under 10 instructional variables. (Author/LAS)
