Before a decision is made, relevant questions, both statistical and judgmental, should be asked. If decisions are not the main purpose of the research investigation, (1) a conditional probability might be reported, (2) confidence intervals could be given as summaries of the data, or (3) a Bayesian approach to inference might be used.

The author analyzes some of the conceptual problems which have prevented a direct test of the discovery learning hypothesis, provides an operational definition of discovery learning, and proposes an improved experimental paradigm. Appended are 38 references. (AA)

Addresses critical decisions that collaborators might encounter in designing, implementing, and reporting collaborative research involving more than one discipline. (Canadian Home Economics Association, 151 Slater Street, Ottawa, Canada K1P 5H3) (JOW)

Argues that the status of the concept of equilibration is classified by considering Piagetian theory as a research program in the sense elaborated in 1974 by Lakatos. A pilot study was made to examine the precision and testability of equilibration in Piaget's 1977 model.(Author/RH)

It is argued that time generalizability exists independent of population and situation generalizability, although the three may interact. Problems associated with sampling and randomization efficacy over time are discussed. (Author/GK)

Describes the development of multisite qualitative research (studies that address the same question in several settings and use similar research procedures in each setting) and its use in educational research. Presents the results of a survey of 25 multisite qualitative educational studies to highlight the design's institutional and methodological…

Discusses the role of research methodology as disciplined inquiry in educational research. Uses examples to address issues of generalizability of results, precision, and choice of research methods. (MK)

To investigate whether research studies on the mildly handicapped have univariate or multivariate research designs, 105 empirical research articles from 1975 to 1979 were reviewed. Factors considered were sample size, type of study, and type of inferential statistic. (SB)

Since fixed and random facets may exist in objects of study as well as in conditions of observation, various modifications of the generalizability theory estimation formulas are required for different types of measurement designs. Various design modifications are proposed to improve reliability by reducing error variance. (Author/BW)

The authors examine the characteristics of a good research question and present a building-block approach for refining the question. They discuss the framework, how to formulate the question, and how to refine the question. A glossary of research terms is also included. (Editor/CT)

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)
