Background information on the testing program, administration details, and a description of the test are provided. The test, intended for administration in June 1986 to third-grade students in Alberta, Canada, consists of two sections. Section 1 is divided into two parts. Part A contains 25 questions covering numeration, geometry, and graphing; 12…

A promising new development in science education is the use of microcomputer-based laboratory tools that allow for student-directed data acquisition, display, and analysis. Microcomputer-based laboratories (MBL) make use of inexpensive microcomputer-connected probes to measure such physical quantities as temperature, position, and various…

Computer graphing makes it easier for students and teachers to create and manipulate graphs. Scale issues are nearly unavoidable in the computer context. In interviews and protocol analysis with six students from grade 8, and 12 students from grades 11 and 12, it became apparent that some aspects of scale are clearly understood very early while…

These materials are intended to provide meaningful mathematical experiences for pre-algebra students. These experiences emphasize the development of computational skills, mathematical concepts, and problem-solving techniques. This bulletin may be used as the basis for the second term of a one-year course, or for the second year of a two-year…

Problem Solving in Mathematics (PSM), a program of problem-solving lessons for grades 4-9, is designed to be integrated into the regular mathematics curriculum. Although the content objectives of the lessons are similar to those of most textbooks, PSM emphasizes problem-solving skills and a variety of instructional strategies which foster the…

The tests for zero partial association in a multiple contingency table have gained new importance with the introduction of graphical models. It is shown how these may be performed as exact conditional tests, using as test criteria either the ordinary likelihood ratio, the standard x squared statistic, or any other appropriate statistics. A…

This paper discusses how various educational inputs have changed in the last decade and examines the impact of those changes on per-pupil salary expenditures. Data for the study, which were obtained from the Missouri Department of Education, cover all certified personnel in St. Louis-area school districts between 1968 and 1976. Analysis of the…

This paper stresses the unified nature of the Languages for Special Purposes (LSP) operation, and argues for increased research at every phase. It deals specifically with the following topics: (1) a procedural ESP model in which the ESP activity is conceived of as a whole, and the various stages in the planning and mounting of an ESP program are…

The major findings and generalizations of nine separate experiments summarized in this report have come out of a program of research on human factors in telecommunications and teleconferencing systems at Johns Hopkins University. These findings, already published in greater detail in the open literature, relate to (1) how people naturally…

In this report, statistical evidence concerning library needs in New York as revealed by surveys of public, school, and academic libraries and school media centers conducted by the National Center for Education Statistics, is presented fully with comparisons to regional and national performance. Resources examined and tabulated include…

Georgia's equalization aid program, intended to meet the varying needs of pupils around the state, does not take into account variations in resource costs between districts. This study, introduced by a review of previous research on the topic, was designed to analyze the impact of these variations in resource costs on equality of educational…

The purpose of this study was to assess school district service capability (full-time equivalent staff per thousand students) as a criterion of program adequacy and to explore the relationship between school district service capability and district enrollment size. Data were collected by obtaining teacher assignment and enrollment for 1977-78 from…

Designed to serve as the basis for systematic collection of statistical information for government and the private sector, this bulletin presents a wide variety of economic indicators in tabular form. The data, selected to facilitate government and private planning efforts, are displayed in 25 tables and 27 graphs. Information is organized under…

This monograph is the third in a series of semiannual reports of research related to reading in secondary schools. The first section of the monograph is made up of three research studies on the validation of teaching procedures to facilitate students' comprehension of content area texts, the graph-reading abilities of seventh grade students, and a…

Although many of the word recognition skills needed to read narrative material are applicable to the language of mathematics, other specialized skills are also required to read mathematics materials. Among the factors contributing to students' problems in reading mathematics are the students' interest and motivational level, their readiness for…
