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doctoral dissertations, statewide assessments, national surveys, journal articles, technical reports, books, and unpublished papers, sought to integrate empirical findings concerning the impact of leisure time television viewing on student achievement in grades K through 12.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…

The Goodman technique of log linear analysis is ideal for family research, because it is designed for categorical (non-quantitative) variables. Variables are dichotomized (for example, married/divorced, childless/with children) or otherwise categorized (for example, level of permissiveness, life cycle stage). Contingency tables are then…

This paper investigates the role of data collection and analysis in the process of legislative evaluation of academic programs, a process which is influenced not only by the expectations and perceptions of both legislators and educators, but, most recently, by consumerism. Before educators can grapple effectively with their concerns over…

The purpose of this paper is to describe the composite caregiver and child behavior variables used in the analysis of the data collected in the National Day Care Home Study: a three-year survey of day care homes in the United States. First, most frequently occurring behaviors are indicated. Then, the factor analyses of patterns of behaviors which…

This paper presents two extensions of the full-rank multivariate linear model that are particularly useful in multivariate analysis of covariance (MANCOVA) and repeated measurements designs. After a review of the basic full-rank model, an extension is described which allows restrictions of a more general nature. This model is useful in the…

This paper reports on a survey conducted to assist the health education faculty of the Nebraska Center for Health Education, University of Nebraska-Lincoln. The objectives of the study were to: (1) gather base line data on the health knowledge and behavior of a sample of Nebraska junior high school students; (2) compare Nebraska junior high school…

The problems inherent in analyzing data in which subjects are "nested" within hierarchical units (such as classrooms or schools), and thus are not independent of one another, are addressed through the use of Joreskog's LISREL model for analyzing covariance matrices. A solution to the problem is proposed and illustrated using data from…

Project SIRA (System for Instructional Response Analysis) used a systems approach to develop a complete range of programs and techniques both for evaluation of student performance and for evaluation and revision of computer-assisted instruction (CAI) lesson material. By use of the PLATO computer-based instructional hardware system at the…

This volume contains the five major addresses and subsequent discussion from the Symposium on the General Linear Models Approach to the Analysis of Experimental Data in Educational Research, which was held in 1967 in Athens, Georgia. The symposium was designed to produce systematic information, including new methodology, for dissemination to the…
