A rationale for using better research designs in evaluating gifted programs is considered. Some definitions of research designs are presented along with evaluation results of a summer program at Northwestern University. The role of research design in evaluating course products, and attitudes is examined via a case study. (Author/CL)

Designed to determine whether abstract and concrete concepts are classified similarly, this study used three separate experiments to explore the vertical and horizontal dimensions used by computer scientists to categorize the common concepts of their field. It found that concrete concept categorization operates over a wider range than previously…

This study examined recent literature describing the Shaken Infant Syndrome and compared it to John Caffey's original descriptions in 1946. Retrospective evaluation of 71 recent cases and 27 case examples offered by Caffey was also performed. Results indicated the recent cases more likely to involve impact trauma, male perpetrators, and admission…

This case study examined prosodic use in a normally developing child between the ages of 20 and 46 months. Conversational repairs were elicited to examine prosodic stress. Fundamental frequency, intensity, and duration of syllables were measured. Although the subject could repair stress errors, a clear pattern of the development of acoustic cues…

The issues involved in conducting educational research are addressed. Some suggestions for methodology that can be used are suggested. Concerns about attempting to carry out investigations that follow the positivist model are discussed. (KR)

This case study describes a 12-year-old boy with autism in association with the folate-sensitive fragile site fra(2)(q13). Cytogenetic results of blood analysis are described, and two possibilities are discussed: the fragile site may be a coincidental finding unrelated to the autism, or may represent an area of potential gene damage.

The diets of three individuals with profound mental retardation and histories of coprophagia (ingestion of feces) were supplemented with a nutritionally complete elemental diet called Vivonex, resulting in decreases in the frequency of coprophagia in all three cases. (DB)

In spite of rapid progress achieved in the methodological research underlying environmental impact assessment (EIA), the problem of weighting various parameters has not yet been solved. This paper presents a new approach, fuzzy clustering analysis, which is illustrated with an EIA case study on Baoshan-Wusong District in Shanghai, China. (Author)

Gains made by a woman with Broca's aphasia as documented by traditional measures were paralleled by changes in conversation, including increased verbal output and efficiency, and changes in conversation-repair patterns. The progress documented with conversational discourse analysis was not observable from other test measures. (Author/DB)

This article presents a case report of a male child with Fragile X syndrome, typical autistic behavior, and cerebellar hypoplasia. Questions are raised concerning the possible role and importance of cerebellar abnormalities in relation to autistic symptoms. (DB)

A sociolinguistic, semantic analysis of intonation was conducted on a 15-minute natural interaction between an aphasic speaker, his wife, and his neighbor. Findings indicated the neighbor made more use of two dimensions of intonation, specifically pitch movements referring to shared information and marked tones, when addressing the aphasic speaker…

Purpose: This paper aims at presenting the theoretical concepts of the transdisciplinary case study approach (TCS), which is a research and teaching approach developed and elaborated at the Swiss Federal Institute of Technology (ETH), as a means of transition support. Design/methodology/approach: The paper reveals the historical roots of case…

This study investigated the role of the family in career development and postschool employment outcomes for young adults with learning disabilities. Using a multiple-case study design, the authors examined a set of family structural and process variables. Fifty-nine in-depth interviews were conducted with young adults, parents, and school staff…

Measurement of clinically significant change is critical for rehabilitation research because it can enhance the credibility of rehabilitation efforts and guide evidence-based practices. The practical appeal of clinically significant change is that it can bridge research and clinical practice by focusing on individual rather than group differences.…

This paper describes how a naturalistic inquirer can demonstrate rigor, or trustworthiness, and how an auditor might assess it. Looking at both inquiry products and processes, Part 1 of this paper describes how an audit may assess whether an inquiry's findings and conclusions are grounded in the raw data, and whether appropriate conventions were…
