This booklet is for wastewater treatment plant operators who find it difficult to follow the detailed discussions and procedures found in "Standard Methods for the Examination of Water and Wastewater." It is intended to be used with "Standard Methods" available for reference. Included in this publication are chapters on…

This booklet presents some methods of quantitative chemical analysis currently used in the field of fresh water pollution control. Only those tests that may be performed with little or no special reagents or pieces of equipment are listed. The booklet addresses the following determinations: (1) acidity; (2) alkalinity; (3) chloride; (4) hardness;…

This document is an instructional module package prepared in objective form for use by an instructor familiar with the determination of color in water using the visual comparison method and the spectrophotometric method.

The first article in this publication concerns radio-telemetry temperature studies of homoiotherms and poikilotherms. Radio telemetry reduces the problems related to demonstrating the differences between "warm-blooded" and "cold-blooded" animals; results may be plotted graphically, compared and used to generate classroom…

The problem of the uncooperative experiment arises with the use of human subjects. Evidence shows that typical volunteer subjects have the following characteristics: better education, higher paying jobs, greater need for approval, lower authoritarianism, higher I.Q. score, and better adjustment to personal questions than nonvolunteers. Data also…

This issue of the newsletter discusses, in much detail, physics equipment useful for the construction of logic units; and alerts science teachers to the fact that ammonia can be made to burn in air. (PEB)

A survey of scientists and engineers who participated in the Presidential Internships in Science and Engineering Program was conducted by a questionnaire to determine the effectiveness of the program in meeting its objectives and to identify some of the characteristics of the interns.

Changes have occurred in the training of interns and the functioning of psychologists at Ohio State University Medical School, some of which was effected by their psychometric laboratory. The number of tests administered by interns has decreased markedly. The existence of the laboratory changed training experiences and opportunities. Psychologists…

The purpose of this study is to determine categories of learning styles based on research on the chemical and physiological correlates of learning, as well as the development of simple measures that would allow an investigator to place a subject within one or more of these categories. The data from eight experiments with rats suggests that there…

The specific hypotheses tested were that: (1) participation in a two-week laboratory changes the cognitive structure of those participating; (2) the extent of change varies with the initial level of cognitive complexity of the participant; and (3) the better the match, as seen by the participant, between the complexity of the learning environment…

This study investigated the influence of the feedback a teacher expects to receive after teaching on his preference for expository or discovery teaching styles. The subjects were 88 undergraduate educational psychology students at the University of Texas at Austin. Each completed a three-part questionnaire, the Teaching Style Inventory (TSI),…

The purpose of this study was to investigate the relative effects of different modes of supervisory feedback on the development of beginning teacher candidates' refocusing behaviors. Thirty-nine secondary teacher candidates served as subjects. They were enrolled in two sections of the course taught by the same instructor and were assigned randomly…

Included is a preliminary report of the analysis of questionnaires returned by biologists teaching in two-year colleges. Data are provided on areas of training, type of previous employment, types of courses taught, measures of teaching load, journals used, and salaries and grants received. The reported information includes the following: two-year…
