Three possible versions of Project Follow Through are discussed to explore the kinds of knowledge that each approach would yield and to describe alternative ways in which the program could maintain the unique feature of federal coordination of research. Versions compared include (1) a federally coordinated research program designed to generate…

The accuracy of trait estimates obtained from three vertical equating methods was examined. The procedures studied included two anchor test designs and a single-group design. Data from two content areas and two grade combinations were studied. A three-parameter logistic model was used to perform the equatings. The results obtained were used to…

In true experiments in which sample material can be randomly assigned to treatment conditions, most researchers presume that the condition of equal sample sizes is statistically desirable. When one or more a priori contrasts can be identified which represent a few overriding experimental concerns, however, allocating sample material unequally will…

A research project was conducted to develop and implement a model for community college missions. The new model would depart from existing models, which utilize a hierarchy of decreasing levels of generality beginning with institutional missions and culminating in objectives. In contrast, this research defined institutional mission in terms of…

Considerations of validity that are central to all disciplines in the social sciences are discussed, and concepts that are an essential part of the intellectual equipment of the social sciences researcher are systematically analyzed. Fundamental methodological concepts underlying decisions made in the research process are highlighted to encourage…

This paper reports on the activities of the National Center for Teacher Education, which is examining what teachers are taught and what they learn in different kinds of teacher education programs. The Center's work combines case studies of different teacher education programs with longitudinal studies of participants' learning. Putting together…

The effects of conditions of informed consent and disclosure on the performance of 84 students doing a statistics laboratory assignment for an introductory graduate course in statistics at a state university in the southeast were studied. Four separate classes taught by three instructors were included. Subjects ranged in age from 22 to 47 years,…

Described are the accomplishments of Project Agam during its first 6 months of operation. Discussion focuses on curriculum materials project staffing, program implementation, related research and evaluation plans, and teacher training. An outline of the projected work plan, including a pilot study and restricted and larger-scale experimental runs,…

Purposes of research in higher education, the issue of research paradigms, and the identification of research questions are discussed in this keynote panel paper. Different purposes of research include conceptual and theoretical development, relating theory and practice, and improving practice. Higher education as a field has not yet given much…

Generalizability theory is based upon analysis of variance (ANOVA) and requires estimation of variance components for the ANOVA design under consideration in order to compute either G (Generalizability) or D (Decision) coefficients. Estimation of variance components has a number of alternative methods available using SAS, BMDP, and ad hoc…

Shared-work compensation (SWC) can provide a method whereby layoffs and unemployment may be avoided by reducing all workers' time. As compensation, workers receive a comparable percentage of their unemployment insurance benefits. Although Western European countries have used work-sharing programs and Canada has implemented an experimental SWC…

Problems associated with the analysis of data collected using the Solomon Four Group Design are discussed. The design includes an experimental group and a control group that have been pretested and posttested, and an experimental and a control group that have been posttested only. A sample problem is approached in three different ways. First, the…

An exploratory study examined the job and life satisfaction of a sample of 32 female entrepreneurs residing in the tri-state area of Maryland, Pennsylvania, and West Virginia. To compare the entrepreneurs' concepts of life and job satisfaction to those of women in more traditional occupations, researchers also studied a sample of 32 female nursing…

The National Assessment of Educational Progress (NAEP), like most large national surveys, employs a complex stratified multistage unequal probability sample. The design provides a rigorous justification for extending survey results to the entire U.S. target population. Developments in the analysis of data from complex surveys which provide a…

This review considers parents' ability to control their children's consumption of heavily advertised, low-nutrition foods and children's ability to control their own consumption of these foods. In particular, research on television advertising's effect on children and children's development of the ability to delay gratification and resist…
