This learning unit on using graphs is one in the Choice Series, a self-learning development program for supervisors. Purpose stated for the approximately eight-hour-long unit is to enable the supervisor to look at the usefulness of graphs in displaying figures, use graphs to compare sets of figures, identify trends and seasonal variations in…

This publication is composed of documentation material and a user's guide for the software used in this course. The materials in this book are extracted from an introductory college mathematics course designed to prepare high school students who have completed Algebra 2 for the variety of mathematics courses encountered in college. The principal…

This report summarizes the work of a two-year project which focused primarily on the problems that students have with algebra in general, and graphs in particular. The first of two major sections in the document deals with the use of computer software to assist in the teaching of graphing. It concludes that thoughtful design and use of graphing…

The use of a three-parameter logistic model for applying latent trait theory has become more popular because of the availability of computer programs. The program Logist 5 can be used not only for the item parameter estimation in the three-parameter logistic model, but also in the two parameter logistic model by setting the third parameter equal…

In order to explain the derivation and implications of the Association of Research Libraries (ARL) Library Index (a descriptive statistical indicator of research library quality which is based on an analysis of certain key library characteristics), this paper discusses regression and correlation as methods for measuring relations between such…

This report presents numerous tables and graphs that summarize data on expenditures for education and other government services by federal, state, and local governments. Most of the data presented are for all or part of the period 1974-76, although some historical and summary data are also included for comparative purposes and to demonstrate…

Divided into five parts, this report describes a research project which used the Delphi method to identify the future roles of the library at Mercer County Community College through 1986, and to set priorities for those roles. The introductory section includes definitions of the problem, the terms used, the subject, and the organization of the…

The use of computers in education and general society is continually expanding, but the growing need for highly educated computer technologists will continue unless universities take major steps toward the reallocation of their resources in favor of the burgeoning computer science departments, and government and industry provide a significant…

This paper discribes the analysis of data in the Management Implications of Team Teaching Project (MITT). It touches on the interviews conducted with teachers and principals, presents the breadth of information obtained in the questionnaire, and explains how the data were aggregated and how issues were grouped. Information collected in the…

This study explores the effectiveness of using graphic illustrations with written text in promoting learning in social studies by junior high students. Two groups of experimental reading materials, one group composed of three narratives with related graphic illustrations and the other composed of three narratives alone, were prepared and…

This is a tongue-in-cheek rendering of an imaginary linguist's attempt to prove that a grammatical rule is not in fact optional, but conditioned. Through manipulation of the data, use of computers, etc., he succeeds in "proving" this. He also "proves" that this conditioning is contextual; that the rule which exhibits it is…

This report discusses use of the Consumer Price Index (CPI) to compute cost-of-living adjustments for wages and salaries in general and teachers' salaries in particular. A number of tables and graphs compare average annual salary increases for Connecticut teachers in 1967-74 with annual increases in the national CPI, the Boston area CPI, the New…

Costs for the use of videocartridges as self-instructional materials in the library are analyzed. A realistic cost per-student-use is detailed for internal productions, BBC, and Open University off-air productions, and other university productions. Previous studies of video usage are presented in considering television material costs. (RAO)

Discusses the interactions of several students involved in a Dutch research project studying student achievement in elementary school mathematics. Results showed progress by most children, particularly those with low scores on the pretests. (TW)

Describes methods and software for graphing representation of a complex function of a complex variable. Includes an application of a graphical interpretation of the complex zeros of the cubic and their properties. (PK)
