This essay reviews progress in empirical economics since Leamer'rs (1983) critique. Leamer highlighted the benefits of sensitivity analysis, a procedure in which researchers show how their results change with changes in specification or functional form. Sensitivity analysis has had a salutary but not a revolutionary effect on econometric practice.…

Qualitative research is a type of research process that is widely used to give people a voice while researching a particular subject matter. In using this research process, one must understand how important it is to develop research questions within the qualitative research process.

Questions traditional approach to validating employment interview. Notes that individuals are likely to differ in ability to accurately predict employee behavior and that interviewers often differ in their constant tendency to make favorable or unfavorable ratings. Researchers, by failing to consider these tendencies, may inappropriately collapse…

This article explores the applicability of interdisciplinary research on the implementation of technological innovations to the field of e-learning research. Arguing that there are important ways in which e-learning systems can be treated as "technological innovations," this article presents a review of several key theoretical and research design…

Written in response to George Fairweather's position concerning the use of experimental studies in evaluation, this paper highlights considerations in deciding when experimental procedures are feasible. The current debate on the use of experimental methods in evaluation is reviewed. (Author/GK)

A number of measurement and design issues that are critical to the use of multiple baseline procedures in evaluating instructional interventions with mentally retarded persons are highlighted. (For related information, see EC 122 157.) (Author/CL)

Discusses a 1993 study by Frazier, d'Arcais, and Coolen intended to test Schreuder's (1990) Morphological Integration model concerning the processing of separable and inseparable verbs. Suggests that the logic of the experiment is flawed and that the data do not warrant the author's conclusions. (DR)

Discusses Kris N. Kirby's work on signal detection theory and its application to Watson's selection task. Identifies problems with the design and interpretation of Kirby's card-selection experiments. (DR)

Discusses Over and Evans' alternative interpretations to Kris N. Kirby's card-selection tasks and finds empirical difficulties. Cites the potentially important contribution of Over and Evans to understanding of the card-selection task by applying the notion of epistemic utility. (DR)

Explores the role of paradigms in information retrieval research and discusses the nature of a paradigm and the applicability of the paradigm concept to a multidisciplinary field such as information science. The features of the physical paradigm and the cognitive paradigm are outlined, and their origins, nature, and role are examined. (55…

A conceptualization of generalization and its place in educational research is proposed. Problems with existing approaches to generalization include limited concepts, misleading or simplistic results, perception variance or change, and the discouragement of sensitivity due to convenience. Researchers should distinguish between conclusions which…

Perspective Text Analysis is a way to measure competence by measuring the strategy of synthesizing, which intelligence tests or questionnaires cannot measure. This paper proposes the use of Perspective Text Analysis in the study of instructional materials. Perspective Text Analysis has been applied in various learning environments, and the results…

By focusing on concepts of power, culture, and ideology in light of new socio-cultural and anthropological interpretations with regard to their use in international, intercultural, and cross-cultural communication research, an outline for the framework of a more hermeneutic-interpretive approach to the study of communication and socio-cultural…
