This document contains three papers concerned with prevention intervention research, a new area of depression research which has shown great promise for contributing new knowledge to the understanding of depression. The first paper, "Clinical Trials vs. Prevention Trials: Methodological Issues in Depression Research" (Ricardo F. Munoz), emphasizes…

The Hawthorne and placebo effects in educational experiments were examined over a 20-year period, as reported in the ERIC, Dissertation Abstracts International, and Psych Info data bases. The literature searches identified 325 studies in education employing the relevant control procedures, and each study was coded for the type of placebo…

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…

A guide to survey research is presented for both novice and experienced researchers. Steps of the survey research process are covered: (1) planning the survey to determine the purpose of the study, collecting background information, designing the sample, and making a time line for completing the project; (2) questionnaire design, including the…

Guidelines for research proposal preparation are presented to assist graduate students. The following components of educational research proposals are described: title page, introduction, methodology, schedule and budget, and bibliography or references. The introductory section enables the researcher to: define the study's purpose, review relevant…

National Institute of Education (NIE) research priorities indicate the use of panel measures only during the time children are in Follow Through programs and further seem to indicate that only implementation variables should be measured. This paper raises questions about the desirability of the narrow focus implied by the NIE priorities, the…

Although the mail survey has been widely criticized as a viable research methodology, it remains the most feasible approach for retrieving data from large, widely-dispersed populations. This paper suggests that there exists a readily accessible body of pragmatic recommendations which, if adhered to throughout the instrument design and data…

Growth curve models are a useful tool for developmentalists because they can estimate an attribute's developmental function by providing a mathematical description of growth on an attribute over time. However, selection of a growth curve model appropriate for estimating individual developmental functions is problematic. The ideal model is the one…

An explanation of the misuse of statistical significance testing and the true meaning of "significance" is offered. Literature about the criticism of current practices of researchers and publications is reviewed in the context of tests of significance. The problem under consideration occurs when researchers attempt to do more than just establish…

Considerable attention has been given to organizational effectiveness of public sector organizations at all levels: local, state, and federal. Public education has not escaped scrutiny. Current examinations of the effectiveness, efficiency, and quality of education are more intense than that of other public sector organizations. The organizational…

Age is often ranked as a significant variable in research studies concerned with the measurement of intellectual and linguistic capacities, including reading. In fact, age is often cited as the cause of a decline in performance on such tasks. However, determining the social, psycho-social, and physiological status of subjects and applying…

There are two general methods of cross-validation: empirical estimation, and formula estimation. In choosing a specific cross-validation procedure, one should consider both costs (e.g., inefficient use of available data in estimating regression parameters) and benefits (e.g., accuracy in estimating population cross-validity). Empirical…

Evaluation research is conceived as a question answering process. Four strategies are suggested which emerged from four approaches to the study of questions. Evaluation questions must be identified and classified before research can effectively begin. This paper discusses the four approaches to studying evaluation research questions and their…

Queries 'n Theories provides a parallel to the strong inference approach to scientific method--designing experiments, observing data, and theorizing. (Author)

The authors developed a questionnaire which asked two basic questions (1) what kind of evaluation was performed, and (2) what changes were made as a result of a survey of Innovations in Elementary Schools. (Author/RK)
