This study reports various aspects of the analyses carried out on the longitudinal data reported in a previous study (PS 007 345) for determining the general growth patterns and growth velocity of mental and motor development. Preliminary analyses focused on the selection of the growth curve, its evaluation in the 208 individual cases, and the…

Presents statistics from 1978 survey of public library patrons concerning relationship between distance and library usage and compares them with results from 1968 survey. Data for branch libraries showing effects of age, education, and mode of transportation used are discussed, and three specific contexts are examined. Seven sources are cited.…

Graphs and charts pertaining to testing in affirmative action are presented. Data concern the following: the predictive validity of College Board admissions tests using freshman grade point average as the criterion; validity coefficients of undergraduate grade point average (UGPA) alone, Law School Admission Test (LSAT) scores, and undergraduate…

The results of a survey are reported in two parts: (1) the compilation of an annotated inventory of recurrent secondary services in education produced in the United Kingdom--abstracting, indexing, and current awareness services; and (2) detailed analyses of the important characteristics of timelag, coverage, physical format, and entry format in…

This study is the first of five studies assembled by the budget committee of the Iowa general assembly to provide information regarding the financing of education by state government. It analyzes general appropriations in the state of Iowa between 1960-76 and compares Iowa's appropriations with those of other states. The results indicate increased…

School finance reform plans have not been accompanied by research demonstrating that they will result in fundamental changes in educational quality. The objective of this study was to quantify school district quality measures and to assess the effects of expenditure levels on these factors. The source of data was the New York State Department of…

The report describes a mathematical modelling activity of a natural phenomenon (transmission of hereditary characters in a codominance case) using the concept of model as a theoretical instrument. The chosen tool enables us to show how the construction of a link between reality and a model is related to the evolution of the graphical…

Examines two databases--MEDLINE and ABI/INFORM--as currently implemented on laserdisk, commercial systems, and local time-sharing in the University of Pennsylvania libraries. The direct costs to the library of installing and operating the three formats are analyzed, and costs and benefits to users are discussed, including comparisons of the…

A survey of 123 users at the National Agricultural Library and Purdue University showed that, for most measures of acceptability, users preferred online or digital videodisc versions of the Pork Industry Handbook to the printed version.

Effects of graphic representations of algebraic functions on performance of tasks involving expression transformations were studied for 28 teachers debugging transformed expressions through syntactic manipulations (SYMs) or semantic interpretation (SEI). Those using SEI improved performance using graphs. Some positive effects of graphic feedback…

Describes a study of the similarities and differences in graph-related interpretations between scientists and college students engaged in collective graph interpretation. Concludes that while many students learned to provide correct answers to scientific graphing questions, they did not come to make linguistic distinctions or increase their…

Concerns about students' difficulties in statistical reasoning led to a study which explored form five (14- to 16-year-olds) students' ideas in this area. The study focussed on descriptive statistics, graphical representations, and probability. This paper presents and discusses the ways in which students made sense of information in graphical…

Information is presented about education in North Carolina. Data are included in the following areas: (1) population; (2) enrollment and attendance; (3) faculty numbers and salaries; (4) general financial resources; (5) governmental revenue; (6) school revenue; (7) governmental expenditures and debt; (8) school expenditures; and (9) miscellaneous…

Surveys were performed in 1977 and 1982 to determine trends in graduate library and information science instruction in five main course categories: library automation, information storage and retrieval, systems analysis, interactive computer systems, and programing. Results of analyses of school course catalogs are compared and current trends are…
