Description: This is a systematic review of studies featuring randomized clinical trials, quasi-experimental designs, or regression discontinuity designs investigating speech and language outcomes for children receiving classroom-based intervention as compared to pull-out intervention.
Question(s) Addressed:
Would a preschool or early-elementary child with language impairment show greater improvement with classroom-based language intervention or pull-out intervention, as shown by improvements in language skills in the areas of phonology, morphology/syntax, pragmatics, and/or vocabulary?
Population: Children between 2 and 8 years of age with a primary language impairment: receptive and/or expressive impairment in phonology, vocabulary, syntax/morphology, and/or pragmatics.
Intervention/Assessment:
- Classroom-based, collaborative team-teaching of receptive and/or expressive language skills
- Classroom-based, non-collaborative teaching of receptive and/or expressive language skills
Number of Studies Included: 3
Years Included: Not stated
Findings:
Conclusions:
"The fact that only three studies were able to meet design-based evidence standards for inclusion in this review highlights the dearth of evidence regarding various service delivery models, and the lack of a clear effect for classroom-based over pull-out intervention in one of the three studies suggests the need for future, rigorous evaluations of classroom-based models of therapy for more conclusive answers" (p. 12).
