Single-case experimental designs (SCEDs) have a long history in clinical and educational disciplines. One underdeveloped area in advancing SCED design and analysis is understanding the process of how internal validity threats and operational concerns are avoided or mitigated. Two strategies to ameliorate such issues in SCED involve replication and…

To draw informed conclusions from research studies, research consumers need full and accurate descriptions of study methods and procedures. Preregistration has been proposed as a means to clarify reporting of research methods and procedures, with the goal of reducing bias in research. However, preregistration has been applied primarily to research…

This highly readable text demystifies the qualitative research process--and helps readers conceptualize their own studies--by organizing the different research paradigms and traditions into coherent clusters. Real-world examples and firsthand perspectives illustrate the research process; instructive exercises and activities build on each other so…

Points out that variability in focus, method, and conceptual level of case studies causes difficulties in validating such studies. Notes method variations raise questions about validity. Claims the validity of case studies lies in their usefulness as projective models. States teachers can generate their own theories where practical educational…

A recent article by William R. Dunlap on admissions criteria is presented to illustrate applied statistical misuse. It is the basis for discussion of severe methodological problems including range truncation, dummy coding, identifying race and sex bias, measuring professional potential, and generalization of findings. The author's response is…

Reviews previous studies that used the Internet for survey research, discusses new methodological issues and problems, and presents a case study that seeks possible solutions. Topics include biased samples and biased returns, access to the Internet, effect of self-selection, validity of respondents, Web browsers, authentication, log files, and…

Naturalistic research should produce reports which afford participants access to the process of interpretation. Naturalistic researchers should anticipate the need for negotiation relationships. However, the consequence of giving participants access to the process of interpretation is that it generates conflict. (JN)

Discusses an ethical dilemma that emerged in a study with bereaved college students. The instruments used to gather data clearly elicited grief-related distress, and more bereaved students in control groups left the study than did participants in social support groups. Three alternatives to a traditional control-group design are discussed for…

A year-long case study of the effects of an educational and vocational rehabilitation program in a youth training center was discussed in terms of fourteen issues which might threaten the validity of an evaluation or research project. This correctional institution housed women aged 14 to 21 who were long-term wards of the state, held on remand, or…

Five criteria are proposed for evaluating performance in research studies: the directness of sampling, the responsiveness of the target, the reliability of the observers, the frequent assessment of the target during the intervention period, and the critical nature of the target. A case study illustrates effectiveness of the criteria. (Author/CR)

If feedback from educational research is not properly related or interpreted, it can often be more detrimental than beneficial. Five factors that should be kept in mind regarding feedback are: (1) varying interpretations of research findings depending on the user, (2) ethical-human aspects, (3) validity problems, (4) interaction effects, and (5)…

Argues that the clinical trial paradigm is the wrong model for educational research. Interpretive case study research suggests that the best thing policymakers can do for educational improvement is to give local educators and school communities more freedom and funding to work out their own ways to improve practice.
