This review of studies comparing early childhood education models focuses on the trends and problems of this kind of research. The 8 "qualitative" studies reviewed, all pertain to aspects of instructional theory centering around teacher-child interaction. In the 19 empirical studies discussed, a dichotomy between "structured and unstructured…

Some of the requirements and consequences of rigorous and valid educational evaluation research are explored in terms of problems in achieving two types of external validity, population and ecological. The former refers to the generalizability of inferences to subjects not included in a study, while the latter is concerned with the…

This article outlines a data collection model designed by Riffel and associates. This model provides information which may assist district and school level personnel in facilitating the desegregation process. (Author/AM)

The story of the national evaluation of the Follow Through program mirrors the difficulties in trying to evaluate a complex social program that changed its community service orientation to a strategy of planned variation of early childhood programs. (Author/MLF)

This paper presents three practical research strategies for facilitating social change in the black community: 1) evaluation, 2) theory-testing, and 3) education and training. These are discussed in relation to the following three variables: researcher relation to the organization, intervention strategy, and the utilization of data. (Author/AM)

Reports on the evaluation of an audiovisual tutorial (AVT) package used in several two-year colleges, finding that the AVT experience has no differential effect on learning for the experimental group. Also discusses basic research problems and offers solutions. (Author/JR)

This study develops a three-stage model of the question-answering process and investigates several potential sources of extraneous variability. Discussion includes implications of findings concerning what it means to "use" library materials and services, adverbs used as response category labels, and subject's responses as predictors of…

Discusses the Teaching Act Model and the very complex set of contexts that determines why each teacher does what she or he does and that makes the appropriateness and effectiveness of those decisions not completely determinable by observation alone. (HTH)

Since the latter part of the 19th century, a fervent debate has ensued about quantitative and qualitative research paradigms. From these disputes, purists have emerged on both sides. Quantitative purists express assumptions that are consistent with a positivist philosophy, whereas qualitative purists (i.e., post-positivists, post-structuralists,…

Author expresses concern about a number of problems inherent in the DD and A processes as they now exist in education and feels that educational practitioners making changes and innovations need to be protected from research and evaluation reports of poor quality. (Author/MB)

The effective school's perspective for evaluating educational programs is not a scientific but rhetorical reform model. Definition of effective schooling must include school-wide and continuing achievement gains. Effective schooling research is geared toward educational policy. Effective schooling research should instruct administrators and…

Reviews the Piagetian description of the stages of development of children's drawings, points out the influence of task demands on drawing performance, and asserts need for a new theory. An alternative framework is discussed and recent research illustrating the alternate theory and methodology is reviewed. (Author/RH)

Discusses research in creativity with particular emphasis on the problems encountered in assessing creativity from a life-span developmental framework. Alternative developmental models and measures are discussed as future research recommendations for the assessment of life-span creativity. (Author/RH)

Three experiments examined what happens to reaction time to verify easy items when they are mixed with difficult items in a verification task. Subjects verification of simple arithmetic equations and sentences took longer when placed in a difficult list. Difficult sentences also slowed the verification of easy arithmetic equations. (Author/RD)

Criteria for suitable research designs for use with large databases are suggested and analyzed. The advantages and disadvantages of several types of quasi-experimental designs are compared. Examples are taken from the authors' research with data from the Manitoba Health Services Commission. (Author/AL)
