The question of generalizability or the usefulness of qualitative research results beyond the confines of the primary site, sample, and study has been hotly debated by qualitative researchers for decades. When examining this question of generalization the first surprising finding is there appears to be no general consensus about the definition,…

Traditionally, research has been seen as a process in which particular cases are studied in order to produce generalisations that can later be applied to other situations. This is arguably the case, for instance, of plain statistical generalisation from samples to populations, but also of grounded theory, local theory and democratic theory. Other…

We reviewed twelve studies that used the constant time delay (CTD) procedure to teach chained tasks to individuals with developmental disabilities from years 1996-2006. Variables analyzed include types of tasks that have been taught with the procedure, how effective CTD has been in teaching participants, and whether researchers have investigated…

Curriculum-based measurement Reading (CBM-R) is an assessment procedure used to evaluate students' relative performance compared to peers and to evaluate their growth in reading. Within the response to intervention (RtI) model, CBM-R data are plotted in time series fashion as a means modeling individual students' response to varying levels of…

The purpose of this study was to examine the dimensionality of the "Contact With Disabled Persons Scale" (CDP). An exploratory factor analysis of the CDP yielded three factors: General Interpersonal Contacts, Positive Contact Experiences, and Negative Contact Experiences. A confirmatory factor analysis provided further evidence for the stability…

A sequential design utilizing identical samples was used to classify mixed methods studies via a two-dimensional model, wherein sampling designs were grouped according to the time orientation of each study's components and the relationship of the qualitative and quantitative samples. A quantitative analysis of 121 studies representing nine fields…

Results of a seven-week sentence stimulation treatment on sentence production in an aphasic adult female with agrammatism indicated that treatment influenced description of test picture sets and that some generalization to other picture sets occurred. (Author/DB)

The paper reviews limitations in social skills research with mentally retarded persons, noting problems in conceptual development, validation of social skills objectives, and generalization. The most serious limitation identified is the failure to demonstrate that community integration and adjustment can be enhanced through training. (CL)

This study investigated the effect of the administration of frequent and infrequent probe lists on generalization with four articulation disordered children (ages 3:10 to 5:8). Results indicated that frequency of probe list administration did not produce any predictable effect on the extent of generalization or the occurrence of a practice effect.…

The study with three blind and mentally retarded adults with additional disabilities found that general case simulation instruction in housekeeping skills led to generalization to untrained settings. Degree of generalization was inversely related to the severity and complexity of participant disability. (Author/DB)

The effectiveness of a cognitive-process approach for teaching appropriate responses to criticism were assessed across three young adults with moderate mental retardation who were receiving vocational training. Results indicated that two participants learned this approach and successfully generalized their behavior across untrained stimuli.…

This study evaluated the "missing-item" language intervention with two moderately to severely retarded students (ages five and six) in a special class setting. The missing-item format produced effects in requests for targeted snack items and, after generalization training, a requesting repertoire that was durable and generalized across…

This study, with 30 students with learning disabilities (grades 6-9) and 15 nondisabled students, found that instruction in a 5-rule summarization strategy significantly increased reading comprehension of expository prose. Strategy use was maintained over time, and students were reported to generalize its use. (Author/DB)

Criticized in this response is research published previously in "The Journal of Environmental Education." Considered are the limitations of the project, experimental design, control of variables, and the use of the case study approach. Includes 35 references. (CW)

Evaluation of an instrumental enrichment program with 80 gifted children (ages 10-12) from culturally disadvantaged backgrounds and a follow-up study 4 years later showed: (1) generalization effects on verbal and nonverbal thinking tasks, and (2) durability of effects on thinking tasks and broad generalization in school achievement.
