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…

Details the 1989 funding proposals for research and development. Describes trends in federal spending. Discusses proportions of funding for the National Science Foundation, the Department of Defense, and other basic research agencies. Includes tables that detail money spent and proposed for many research agencies. (CW)

Library circulation records for five years in one Hawaiian elementary school were analyzed to discover patterns according to sex and grade level; identify titles, subjects, and types of books circulated; and determine circulation of Hawaiiana and books about Asia. Bibliography of 129 titles mentioned in text is included. (11 references) (EJS)

Using factor analysis, seven socioeconomic indicators and three information activity indicators (written communications, technology, and libraries) were derived to relate social and economic conditions in less developed countries with measures of information activity. Information activity variables are appended. (17 references) (EJS)

The advanced study program sponsored by the U.S. Naval Academy for the Anne Arundel Public Schools is described. Graphs, Games, and Puzzles and Strange Algebras are two of the courses presented. (MNS)

Both on-line and face-to-face courses rely on textbooks as an important source of information for students. A challenge for instructors in an on-line setting is to insure that students are learning from their textbooks. One way to address this challenge is to use productivity software tools to develop assignments that promote student thinking and…

This book is intended for those teachers who want to create more dynamic classroom lessons and presentations using quick and easy custom animations. The focus of this book is to explain how to use PowerPoint to create transitions, graphics, charts, graphs, and sound effects in a format that makes learning fun. The book is designed to give…

Assuming that dynamic features of Dynamic Geometry Software may provide a basic representation of both variation and functional dependency, and taking Vygotskian perspective of semiotic mediation, a teaching experiment has been designed with the aim of introducing pupils to the idea of function. First data coming from the observations in Italian…
