Two order theoretic techniques were presented and compared. Ordering theory of Krus and Bart (1974) and an extended Takeya's item relational structure analysis (IRS) by Tatsuoka and Tatsuoka (1981) were used to extract the hierarchical item structure from three datasets. Directed graphs were constructed and both methods were assessed as to how…

Numerous forms and meanings of validity have been developed to provide researchers with the opportunity to assess the many potential sources of ambiguity that exist in any research finding. A Validity Network Schema (VNS) developed by Brinberg & McGrath (1982) is extended and elaborated in order to describe the components of the research…

An examination of problems inherent to class size concepts suggests possible arrangements, given limited resources, for providing optimal classroom environments. Among the problems in determining class size are ambiguous definitions, measurement problems, and contradictory research findings. Traditional definitions of class size ignore such…

This booklet contains the proceedings of a conference designed to elicit discussion, reactions, comments, and recommendations with respect to the value, desirability, significance, and budgetary problems involved in carrying out scientific research programs at comprehensive universities (those having either no Doctor of Philosophy (Ph.D.) programs…

This study investigated the effect of different implicit definitions of equality upon children's performance on conservation tasks. In the study, traditional versions of conservation tasks are compared to modified versions in which initial equality is established through verbal counting of discontinuous quantities and measuring of continuous…

The adequacy of mean length of utterance (MLU) as a criterion for matching retarded and normally developing children was investigated. Six normally developing and four retarded subjects were matched on MLU. Although matched on MLU, these two groups of children demonstrated both quantitative and qualitative differences in their use of language.…

The large number of dropouts estimated by the California State Department of Education has caused concern for educators, lawmakers, and the general public. A 1985 investigation of the graduation rate of the 1979 freshman class of San Juan High School was conducted which also sought to identify logistical problems with the collection of data needed…

It has been suggested that surveys dealing with the incidence of crime among the elderly do not take into account the varying individual and group levels of fear and exposure to threat of victimization. Data from Law Enforcement Assistance Administration surveys were used to review the personal victimization of older persons, incorporating the…

The problem of change scores' correlation with initial status and the problem of low reliability in the measurement of change are addressed. By treating the correlation between initial status and change as a design problem rather than a statistical issue, research questions can be formulated in terms of changes in the shapes of growth curves…

Exploratory research suggests that denominational preferences, fundamentalism, and church attendance are related to an individual's position on political issues. A review of research reveals that religious beliefs are stable, developed early in life, and are central to an individual's other orientations. Research on religious orientation is…

A persistent problem in the evaluation of field-based projects is the lack of no-treatment comparison groups. Frequently, potential comparison groups are confounded by socioeconomic, racial, or other factors. Among the possible methods for dealing with this problem are various matching procedures, but they are cumbersome to use with multiple…

Because cognition is inherently inaccessible to observers, researchers interested in cognitive approaches to argumentation frequently rely on self-reports for data. Opponents to self-reports argue that such data have very limited value. They claim that when subjects are put in a position where they have to tell more than they can know, they…

The purpose of this annotated bibliography is to provide the reader with a guide to relevant research in the area of Gestalt therapy, techniques, and methods. The majority of the references are journal articles written within the last 5 years or documents easily obtained through interlibrary loans from local libraries. These references were…

Naturalistic inquiry (based on the ethnographic research paradigm) has the potential to supplement, or possibly to replace, quantitative experimental research in education. For years most reading researchers have used the experimental research design. This design fails to tap self-concept, value systems, purpose of and attitude toward reading,…

Noting the increasing interest in qualitative research in general and ethnographic research in particular, the authors of this report clarify the place of the latter within the former. The authors present six criteria for an ethnographic approach to education, illustrated with examples, and discuss ethnography's advantages and disadvantages. The…
