The role analytical instrumentation performs in the surveillance and control of the quality of water resources is reviewed. Commonly performed analyses may range from simple tests for physical parameters to more highly sophisticated radiological or spectrophotometric methods. This publication explores many of these types of water quality analyses…

Bounds for the tails of Dirichlet integrals are established by showing that each integral as a function of the limits is a Schur function. In particular, it is shown how these bounds apply to the simultaneous analysis of variance test and to the multinomial distribution. (Author)

Two vocabulary tasks--one production and one recognition--were compared with the expectation that the recognition task would yield better performance than the production task. The pairs of pictures used in the recognition task were divided into eight groups defined on target and distractor frequency and same-different conceptual category…

A study was conducted in which the infants' behavior was allowed to control stimulus duration. A group of five infants were tested once a week from 3 through 14 weeks of age. A second group of five infants were tested once a week from 8 through 14 weeks of age. A third group of 18 infants were tested once at 3, 8, or 14 weeks of age. Once a…

Physical, mental, and socio-cultural variables were associated with performance on the Life-Science Concept Acquisition Test (L-SCAT), developed by the investigator. The usefulness of the variables as predictors of performance on L-SCAT was also investigated. The L-SCAT was administered as a picture-stimulus structured interview to each of 51…

Recent theoretical developments have suggested that understanding the thoughts contained in prose material and storing the information contained in prose material are the same thing. A test which was purported to measure the information stored during the reading of prose passages was found to correlate .98 with subjective estimates of the percent…

This study compares the effects of a compressed speech program transmitted via the Educational Telephone Network (ETN) system on various professional adult groups throughout Wisconsin with that of a program transmitted at normal speech. It is concerned with the noise source, receiver and destination aspects of the Shannon Weaver communication…

Report 7 from the National Assessment of Educational Progress, a project of the Education Commission of the States, is based on results from a 1969-70 assessment of scientific knowledge and extends these results to cover the performance of Blacks, of respondents with differing levels of parental education, and from differing types of communities.…

THE JUNIOR COLLEGE ENVIRONMENT OF A RESIDENTIAL, 2-YEAR PRIVATE COLLEGE FOR WOMEN WAS INVESTIGATED IN TERMS OF THE FIVE DIMENSIONS MEASURED BY THE COLLEGE AND UNIVERSITY ENVIRONMENT SCALES (CUES)--PRACTICALITY, COMMUNITY, AWARENESS, PROPRIETY, AND SCHOLARSHIP. ALSO, THE STUDY WAS DESIGNED TO--(1) COMPARE THE PERCEPTION OF CHARACTERISTICS BY…

The purpose of this study was to determine if answer sheet design, particularly a self-scoring answer sheet, was a differential variable of test anxiety. Data for the study was gathered from the administration of pre and post anxiety tests, given in conjunction with an in class psychology exam. Students in the control group used conventional IBM…

Suggests a monolingual, strictly oral "multiple choice" testing system, with suggestions regarding method, correcting and grading. (Text is in German.) (IFS/WGA)

Reports on an experiment designed to test the reliability of the cloze procedure in second language testing, specifically as a measure of overall language proficiency, and as a measure whose results are independent of style. (AM)

Presents a measurement instrument for evaluating a second language learner's oral skills, which is based on a mathematical theory of communication, and which relies on native speaker judgment. (AM)

Discusses the value of self-evaluation to the adult second language learner; the tools of self-evaluation; and the relationship of self-evaluation to other forms of evaluation, to learning, and to instruction. (AM)

Two classroom teachers take a critical look at what the double exam system means for the children they teach. (Editor)
