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)

This article presents a fairly quick, easy way to decide what size sample is needed for a survey, given a desired level of confidence and degree of accuracy. The method proposed will work on any multiple response instrument. A technical mathematical explanation is also included. (GK)

Restriction in range is a measurement problem frequently encountered in research studies that utilize correlation coefficients. A FORTRAN program is described that can compute the estimated unrestricted correlation coefficient in either the explicit or implicit case. The user selects the appropriate formula to be employed from five that are…

Contrasts the naturalistic research paradigm with the scientific model, noting that the naturalistic paradigm assumes multiple reality, subject-object interrelatedness, and contextuality. Skills required for the pursuit of naturalistic inquiry are described. (JEG)

The article illustrates a method to estimate changes in the statistical power of a study which are caused by changes in the reliability of the dependent variable. (Author)

This paper surveys available techniques and introduces an explicit statement of a new statistic to test for equality of correlated proportions in a polychotomous response design. A set of guidelines for the potential user of the techniques is provided. (Author/CTM)
