This publication provides projections of statistics for elementary and secondary schools and institutions of higher education. Projections for the 10-year period from 1969 to 1979 are made for enrollments, graduates, teachers, and expenditures. Based mainly on 1958-59 to 1968-69 data, these projections assume that the past 10 years' trends in…

This bibliography on the tools and applications of operations research, management science, industrial engineering, and systems engineering lists many entries which appeared between 1961 and 1966 in 186 periodicals and trade journals. Twenty-six texts in operations research are also listed along with an indication as to which of 37 techniques or…

This bibliography is a first edition designed to aid the work of the Textual Communication Research Unit and will be followed by a further edition in two years' time. Sources relevant to textual communication, except those pertaining exclusively to broadcasting or children's texts, are arranged as either pertaining to language or to visual design.…

This study is the sixth in the series "Studies in the Phonology of Asian Languages." A phonetic and phonemic analysis of the three complex nuclei of Vietnames (Hanoi dialect), spelled (1) ye-, -ie-, -ia, (2) -u'o'-, -u'a, and (3) -uo-, -ua, was carried out using the sound spectrograph. The relative domains of the target qualities of the…

This document contains a State-by-State directory of 464 alternative public schools. Each listing in the directory contains the school name, address, grade levels, and enrollment. For purposes of this directory, an alternative public school has been defined as any school within a community that (1) provides alternative learning experiences to the…

At vowel onset following unvoiced consonants in /h-cvc/ utterances spoken by two talkers, Fo began high and fell about seven percent in the first five centiseconds. At closure of voiced oral obstruents, Fo suddenly dipped about ten percent, remained flat, suddenly rose about twenty five percent at opening of closure, and, after vowel onset,…

Recent studies of rising intonation contours in French, in particular the acoustical differences that serve to distinguish Yes/No questions from other rising intonations are reviewed. The preliminary results of a pilot study of rising intonations in French, in which average curves were obtained from spectrographic measurements of fundamental…

This publication provides projections of statistics for elementary and secondary school and institutions of higher education. Projections for the 10-year period from 1970 to 1980 are made for enrollments, graduates, teachers, and expenditures. Based mainly on 1959-60 to 1969-70 data, these projections assume that the past 10 years' trends in…

This publication is a part of a series of reports on public broadcasting. Statistics on financial, employment and broadcast and population activities of 155 public radio stations in the United States and Puerto Rico are included. The first section covers total funds, direct operating costs, capital expenditures, and other financial topics. The…

Argues that first-year algebra should be taught in eighth grade. Outlines an algebra course that could provide average students with a working kowledge of algebra. Proposes that this would require students to have experiences with variables, equations, formulas, and graphs during previous years of study. (TW)

Explores graph theory and use of topological indices to predict boiling points. Lists three indices: Wiener Number, Randic Branching Index and Molecular Connectivity, and Molecular Identification numbers. Warns of inadequacies with stereochemistry. (ML)

For 83 low-achieving elementary students, predictions of future performance were computed on the basis of reading and written expression data and were subsequently compared to actual data. Analyses indicated that predictions were more accurate when the data had been graphed on equal interval graphs rather than semilogarithmic charts. (Author/JDD)

It is argued that microcomputer technology has evolved to the stage that it should be routinely used by mathematics students at all levels. It is shown how the use of microcomputers can change the way problems are solved. Computer-generated graphics are highlighted. (PK)

The article considers the problem of how to plot on the computer screen a circle with center (A,B) and radius R. Several different procedures are discussed and compared. (PK)

Discusses how to examine and evaluate claims of improved academic performance in advertisements for computer-assisted instruction. Highlights include the proper use of comparison groups; types of statistical analyses; the Hawthorne effect; the interpretation of scores; interpreting graphic presentations; tests of significance; and cost…
