Presents the author's views on the nature of educational intervention in learning disabilities through a discussion of distinctions between intervention, remediation, tutoring, and accommodations; optimal characteristics of intervention research; ethical issues, research design, and measurement of change; and barriers to conducting intervention…

Proposes a research model to test the dependence of a field list of internationally visible journals on the initial set. Outlines applications of the experiment and hypothesizes on the validity of the Institute of Scientific Information's (ISI) impact factors. Suggests that in some cases lists of journals selected by linguistic or geographic…

Fourth- and fifth-graders were taught how to design simple unconfounded experiments using one of two instructional methods differing only in whether children manipulated physical or virtual materials. Results indicated that the two types of materials were equally effective in achieving several instructional objectives, including the design of…

Argues that only positive results in a reading-level (RL) match and negative results in a chronological-age (CA) match are interpretable; negative results in a CA match and positive results in a RL match are not. Argues that using the RL control is only a first step in research into reading disability. (RS)

Reviewed are the basic concepts of experimental design, analysis of data, and optimization. Discussed are two-level factorial designs; fractional factorial designs and blocking, additive, linear, and quadratic models; quadratic and composite designs; and designing experiments in design. (CW)

Examines issues associated with the design of and statistical inferences from embedded experiments which vary the questionnaire content into sample surveys of broad populations. Provides an example of context effects in attitude surveys, a summary, and conclusions. (RT)

Discussed is the issue of the appropriateness of applied science approaches to evaluation in environmental education. The relationships between characteristics of applied science approaches to evaluation and the special characteristics of environmental education are explored. (Author/YP)

The paper reviews a construct validation framework for research on the selection and evaluation of residents. The application of the proposed methodology to surgery residents is described. The need to measure non-cognitive and neuropsychological factors in addition to cognitive knowledge and technical ability is emphasized. (Author/MLW)

Describes two ways to conduct research on the distinctive features of an institution: by establishing a college committee or by hiring an outside consultant. Considers the steps involved and the advantages and disadvantages of each approach. (DMM)

Two case examples illustrate how single-case designs (alternating treatments, multiple baseline, and reversal) can be used to evaluate manipulable influences on school performance. In each case, the success of an intervention plan is evaluated within the single-case design. (SLD)

Presents an alternative to the research-development-diffusion model of mathematics education based on an integration of curriculum research and design embedded in educational development. Explicates the characteristics of developmental research and discusses its methodological aspects. (53 references) (Author/MKR)

Although Grusec and Goodnow provide a compelling framework for organizing disciplinary encounters found to affect moral internalization, their hypothesis remains untested. Researchers need to devise conceptually sound measures of message acceptance and show that message acceptance does indeed mediate internalization before committing themselves to…

This paper provides an overview and discussion of a study of young children's knowledge and understanding of the management of waste materials. It describes a semistructured interview and discussion methodology used to ascertain details of children's knowledge and misconceptions about this key environmental issue. (LZ/Author)

Discusses challenges to conducting research on effectiveness of community service systems that are family-based and school-centered: underidentification of children with emotional or behavioral disorders, lack of concordance between diagnostic criteria used in school versus mental health systems, problems of comorbidity, analysis of data from…

Strategies are presented for analyzing longitudinal research designs with many waves of data using hierarchical linear modeling. The approach defines well-focused parameters that yield meaningful effect size estimates and significance tests. It is illustrated with data from the Boys Town Follow-Up Study. (SLD)
