Six major problems confronting attempts to use nonmetric multidimensional scaling to represent structures underlying similarity data are identified and the author's prospects for over-coming each of these problems are presented. (RC)

Describes and evaluates a circuitless flow model for forecasting future student attributes and enrollment projections, compared with a simple Markov chain model. Data from a study of secondary students are used to illustrate the analytical methodologies and to contrast results of the Markov chain and circuitless flow models. (JG)

This paper describes several computer-based strategies for producing secondary school schedules and presents the results of research into the feasibility of determining optimal teacher-course assignments by use of an operations research model. (Author/JG)

This article is based on the senior author's unpublished doctoral dissertation, Purdue University, 1968.

The purpose of this paper is threefold: to describe grounded theory research strategies, to present a summary of several studies in education that have followed this approach, and to explore the potential uses of the grounded theory techniques in curriculum theory generation. The paper is arranged into six parts. In the first and second parts of…

This paper is based on the premise that relatively little is known about how to improve validity in qualitative research and less is known about how to estimate validity in studies conducted by others. The purpose of the study was to describe the conceptualization of validity in qualitative inquiry to determine how it was used by the author of a…

This training manual presents material on the use of a compound microscope to analyze microscope communities, present in wastewater treatment processes, for operational control. Course topics include: sampling techniques, sample handling, laboratory analysis, identification of organisms, data interpretation, and use of the compound microscope.…

This report presents concepts, procedures, and instruments to be used in studying staff development in educational settings. The report has been structured as a set of guidelines designed to help state agencies, county offices, teacher centers, universities, school districts, and local school faculties collaborate in investigating the dynamics of…

A review of 23 studies, including doctoral dissertations, statewide assessments, national surveys, journal articles, technical reports, books, and unpublished papers, sought to integrate empirical findings concerning the impact of leisure time television viewing on student achievement in grades K through 12. For each study, the reviewers coded the…

This follow-up study had three objectives: (1) provide information about dropouts that could be used by the college to identify areas where corrective action may be needed; (2) document the number and percentage of students who leave the college for reasons not amenable to corrective action; and (3) provide insight necessary to build models that…

This overview acquaints prospective users with the School Finance Equalization Management System (SFEMS), a computer-based system designed to answer questions about state aid distribution. SFEMS can determine such things as the current pattern of aid distribution, the current pattern of tax effort, or the effect of alternative expenditure and…
