This poem, with stanzas in limerick form, refers humorously to the many threats to validity posed by problems in research design, including problems of sample selection, data collection, and data analysis. (SLD)

After the terms "qualitative research" and "quantitative research" are defined, this paper considers why it makes sense to integrate these approaches, at least under some circumstances. This discussion necessitates attention to the issue of whether quantitative and qualitative research are inextricably linked to incompatible…

The critical issues, in a dispute between Romney's interpretation of his results and Gillmore's interpretation, are described as whether the teacher factor should be treated as fixed or random in the analysis of variance model and what conclusions can be drawn from the results of the study. (Author/MLW)

Focuses on rape prevalence research and examines the relationship between measurement methods and levels of rape detection. Weighs the relative threat to the validity of prevalence estimates posed by fabrication versus nondisclosure. Examines various methodological choices and their relationship to the magnitude of prevalence estimates. (JPS)

This brief report highlights the issues, evidence, and first steps toward including students with disabilities in educational data systems. The report notes that if students with disabilities are excluded from educational data collection systems, policy makers do not have an adequate set of information from which to make policy decisions. The…

The data collection program of the National Center for Education Statistics (NCES) should be designed for maximum reliability, validity, and manageability for all involved organizations. An adequate number of school districts should be sampled to produce useful data. Data should be more comparable between states if proper sampling techniques are…

From a priori and post hoc data collection perspectives, this paper describes the interrelations among (1) power, alpha, effect size, and sample size for hypothesis testing; and (2) precision, confidence, and sample size for interval estimation. Implications for special education researchers working with convenient samples of fixed size are…

This paper analyzes data needs for policy purposes and is divided into three sections: (1) revenue and expenditure data; (2) human resources data; and (3) time and curriculum resources data. Federal data collection concerned with resources should identify the state as the unit of analysis, should broaden the definition of resources beyond revenues…

An assessment of the Higher Education General Information Survey (HEGIS) reveals that small colleges can benefit from the consistency of standardized responses in creating individual planning data systems. HEGIS has a long enough history to have stabilized its several instruments. However, if one is looking to create student or personnel specific…

Grounded theory, generated from data systematically obtained through the constant comparative method, is suggested as a research strategy for higher education. Greater emphasis is placed on qualitative data while using quantitative data when obtainable and pertinent. Higher education research can thereby be redirected to development of theory.…

The failure of educational research to fully allow for limitations in methodology when drawing conclusions is faulted. In addition to this, a failure on the part of the media--educational and other--to fully publicize these limitations is also criticized. Methodological shortcomings of the 1977-78 American Institutes of Research (AIR) study of…

After a brief introduction indicating the value of the first Follow Through evaluation, this document offers ideas about how a new wave of Follow Through approaches should be evaluated. The discussion is based on the premise that the form of an evaluation must be derived from the questions for which answers are sought, the audience(s) to whom the…

Reports on a study of the beliefs held by students, parents, and teachers regarding desirable schooling and teaching in grades one to eight in Porto Alegre, Brazil. Examines the combined use of qualitative and quantitative research methodologies; rationales and procedures of naturalistic and rationalistic inquiry; and implications for research in…

The National Assessment of Educational Progress (NAEP) is compared to the two studies of the National Educational Longitudinal Studies (NELS) Program--the National Longitudinal Study of the Class of 1972 (resurveyed in 1973, 1974, 1976, and 1979) and the 1980 High School and Beyond study (partially resurveyed and retested in 1982). The third phase…

The National Assessment of Educational Progress (NAEP) and the Longitudinal Studies Program (LSP) are major survey projects on educational outcomes performed by the Center for Education Statistics. NAEP is a continuing cross-sectional survey of young Americans' skills, knowledge, and attitudes. The LSP studies follow a sample of students as they…
