Addresses concerns about the trustworthiness of research results derived from image-based data, particularly questions of validity assessment. Compares examples of such research to provide an illustration of these issues. Presents a tentative strategy for ensuring trustworthiness based on five criteria: completeness, interpretive adequacy,…

The use of messages as experimental stimuli brings with it problems regarding the interpretability and generalizability of findings. Some psychologists and communication researchers have argued that message stimuli must be treated as random effects. A review of the literature examined data regarding experimental designs used in recent…

Psacharopoulos has found a declining rate-of-return to education pattern across levels of per capita income, using international data. A reexamination of Psacharopoulos's cross-country data refutes his declining rate-of-return hypothesis and points to diversity of cross-country experience as a possibly significant factor in interpreting the data.…

This articles explores authoritive problems in interpreting art education in research, namely authorization and authorship. Authorization rites and rights are now under institutional surveillance. A researcher should proceed with ethical fairness. The process of authorship is one of the negotiation of conflicting meanings, and at times subject to…

Bias due to attrition of respondents poses a threat to the internal and external validity of research findings. Discusses methods of detecting attrition bias in longitudinal family research, and presents Heckman's procedure to correct attrition bias. Data from the University of California Longitudinal Study of Generations are used to illustrate…

This paper compares the results of National Center for Education Statistics (NCES) and the Carnegie surveys of postsecondary faculty and notes the differently constructed samples, the different response rates, and different weighting schemes in analysis and interpretation. Inconsistencies in the surveys' results are identified and methodological…

Problems with using stepwise analytic methods are discussed, and better alternatives are illustrated. To make the illustrations concrete, an actual data set, involving responses of 91 medical school admissions directors to 30 variables, was used. The 30 variables involved perceptions of barriers to medical school with respect to characteristics of…

Dealing with data from multiple family members presents problems for researchers, as many of the techniques available for dealing with such data are problematic, and there is no way that is unique to each family. Proposes and gives an example of the use of Q factor analysis as a means of combining data from multiple family members in a unique way…

Describes a class demonstration of observer bias in which students were led to believe what the research data would indicate. Reports that students reported trends consistent with the expectancy. Asserts that the demonstration had a strong and memorable effect on students and has value for demonstrating observer bias. (CFR)

In response to a frequently articulated call for "ecological" validity from instructional communication investigations, this paper reports on methodological issues which evolved during the development and application of a coding scheme for content analyzing teacher compliance-gaining messages. Starting with a consideration of the…

Deterministic chaos which involves orderly motion is discussed. Presented is the history of chaos and two tests for chaos. Practical applications and predictions of the long-term significance of chaos research are discussed. (KR)

A major focus for research in preparation programs should be on the practice of administration. For some time, the preparation of educational administrators has been rooted in the traditional liberal arts approach--the approach of a discipline--as a model for preparing the practitioner. Emphasis has shifted to the concept of the accurate…

Describes three classes of measurement techniques: (1) interviewing methods; (2) record retrieval procedures; and (3) observation methods. Discusses primary reasons for measurement error. Concludes that, although measurement error can be defined and controlled for, there are other design factors that also must be considered. (CFR)

The efficiency and appropriateness of the cassette tape as a data collection medium was considered in this survey. A 19-item questionnaire was mailed to 117 agricultural teacher educators who had served at foreign locations. Most of the questions solicited qualitative data about their experiences, problems, and accomplishments. Respondents were…

Asserts that traditional approaches to multivariate analysis, including standard linear regression techniques, ignore the special character of count data. Explicates three suitable alternatives to standard regression techniques, a simple Poisson regression, a modified Poisson regression, and a negative binomial model. (MJP)
