This packet includes 51 statistical profiles, based on the 1980 census, of American Indian and Alaska Native populations in all states and the District of Columbia. All profiles contain bar graphs illustrating data on total population, urban-rural distribution, counties and places with the largest American Indian populations, median age, families…

The result of cooperative research between Statistics Canada and the United States Bureau of the Census, this report presents tabulations of the demographic, economic, and social characteristics of persons born in Canada and counted in the U. S. Census of 1980 along with persons born in the United States and counted in the Canadian census of 1981.…

This document contains reproducible black and white materials for teaching about the 1990 United States census. There are maps, charts, and graphs of population projections by region; historical census data; projections of populations changes; world population; minority population figures; age charts; number of dependents; housing units;…

Graphing is a common and powerful symbol system for representing concrete data. Yet research has shown that students often have graphical misconceptions about how graphs are related to the concrete event. Currently, the Technical Education Research Center (TERC) is developing microcomputer-based laboratories (MBL) science units that use probes to…

In order to estimate the classical coefficient of test reliability, parallel measurements are needed. H. Gulliksen's matched random subtests method, which is a graphical method for splitting a test into parallel test halves, has practical relevance because it maximizes the alpha coefficient as a lower bound of the classical test reliability…

This study examined problem solving as a function of display type (table/graph) and numeric function (linear/nonlinear) in four problem solving domains. Twenty-two stimulus problems were developed, and line graph and table displays were constructed for each problem. Half of the displays contained linear numeric functions and the other half…

This paper summarizes the findings of a 1976 national survey on usage of paper-to-paper photocopying machines in the U.S. libraries, which was conducted by King Research, Inc. for the National Commission on Libraries and Information Science, the National Science Foundation, and the National Commission on New Technological Uses of Copyrighted Works…

In the winter term of 1979-1980, 692 faculty members and 1,319 students responded to a library use study conducted at the Technishe Universitat Wien (Vienna, Austria). Among other topics, the hours of operation of the main library were studied. Results show that more than 50% of the faculty and more than 70% of the students consider the…

One hundred and ninety-four NCA postsecondary members give their perceptions of the contributions, problems, and possible modifications of accreditation as conducted by the NCA Commission on Institutions of Higher Education. (Editor)

The author describes a new graphing algorithm for computing probabilities, and presents problems for these algorithms for use in the classroom. (SD)

The Czechoslovakian Academy of Sciences is sponsoring an experimental approach to the modernization of the geometry curriculum. Geometry is viewed as ancillary to other parts of the curriculum and is taught as appropriate to other subjects (e.g., algebra). Combinatorial geometry is taught formally. (SD)
