Over the past few years, the focus group method has assumed a very important role as a method for collecting qualitative data in social and behavioural science research. This article elucidates theoretical and practical problems and prospects associated with the use of focus groups as a qualitative research method in social and behavioural science…

The reluctance to use film and video equipment for systematic observation and recording can be partially attributed to an assumption of reactivity and internal invalidity. The results of the study discuss placement of the observer and the use of film in data collection. (Author/DEP)

Presents a method for the collection and analysis of collateral data about research subjects (i.e., measurements of events in subjects' lives that may affect outcome measures and/or lead to attrition). A six-step procedure evaluates bias resulting from subject attrition from a study using data from lost and retained subjects. (SLD)

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)

Notes that major changes have occurred in the factors investigated and the data collection procedures employed in teacher effectiveness research and that the generalizability of significant findings continues to be limited by methodological and experimental design problems. (FL)

Reliability and validity of self-report data provided by 178 mentally ill homeless persons were generally favorable. Self-reports of service use also generally agreed with treatment staff estimates, providing further validity evidence. Researchers and administrators can be relatively confident in using such data.

Raises concerns about using interview data in phenomenological research, arguing such data are more related to discourse and the interviewee's perception of what is appropriate to say in the context than to "ways of experiencing," which is the object of study in phenomenography. Also argues that in important respects, discursive…

Some of the requirements and consequences of rigorous and valid educational evaluation research are explored in terms of problems in achieving two types of external validity, population and ecological. The former refers to the generalizability of inferences to subjects not included in a study, while the latter is concerned with the…

This article outlines a data collection model designed by Riffel and associates. This model provides information which may assist district and school level personnel in facilitating the desegregation process. (Author/AM)

Problems with the scope, validity, and accuracy of statistical data on Puerto Ricans have led to difficulties in research on that population. This situation has contributed to the restricted access of Puerto Ricans to government-sponsored programs and to public services, such as education, that are necessary for social equality.

This paper presents a rationale for observing black mothers during semi-structured play activities with their toddlers. It appraises the strengths and weaknesses of such situational assessments of mother-infant dyads, arguing that in addition to observational data the collection of introspective interview data from mothers is essential. Interview…

This chapter presents a number of problems related to designing local-level summative evaluation studies and suggests solutions to these problems. Three general areas are covered. First, many of the motivational, organizational, and attitudinal constraints likely to face the local-level evaluator are discussed. Second, various threats to the…

In order to assess the methodological merit of the published research in educational administration based on surveys, the authors analyzed data from a random sample of 24 survey studies published in the "Education Administration Quarterly" and the "Journal of Educational Administration."
