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…

In this paper we report an analysis of a teaching sequence in which Grade 11 students were asked to produce some graphs corresponding to the relationship between time and distance of a cylinder moving up and down an inclined plane. The students were also asked to carry out the experience using a TI 83+ graphic calculator equipped with a sensor,…

This collection of lesson plans and activities for students aged 9-11 years is based on a science curriculum developed by a group of Caribbean nations. The activities pertain to topics such as place value, prime and composite numbers, the sieve of Eratosthenes, square numbers, factors and multiples, sequences, averages, geometry, symmetry,…
