This replication study focused on the effectiveness of two different intervention approaches, activity-based intervention and embedded direct instruction, on the acquisition, generalization, and maintenance of phonological awareness, a key area of emergent literacy, by preschool children with language delays. Five male preschool participants with language delay were treated with a modified alternating-treatments design. Embedded direct instruction was more effective and efficient in the acquisition of phonological awareness skills for preschool children with language delays. Embedded direct instruction was also more effective in the generalization of emergent literacy skills to probe generalization sessions, as well as in the percentage of maintained skills. Preschool children who are at risk of acquiring foundational skills necessary for the development of conventional literacy would benefit from an explicit, systematic instructional approach. Embedded direct instruction provided the structure necessary to promote effective and efficient acquisition of skills, as well as generalization and maintenance of learning.
In this article, a model of evidence-based practice is presented that engaged graduate students and instructors from the discipline of communication sciences and disorders (CSD) in evidence-based education through the use of the scholarship of teaching and learning (SoTL). This article can serve as a starting point for other instructors interested in engaging in SoTL in their own CSD classrooms.
Speech-language pathologists are faced with an increasing demand to conduct language and literacy assessments for children who are from cultures different from their own. Cross-cultural assessment is challenging. This article outlines the conditions necessary for successful implementation of culturally appropriate models of assessment. Alternative approaches to assessment are proposed that will guide speech-language pathologists about where, when, and how to assess children. Embedded approaches, authentic approaches, mediated approaches, and comprehensive models offer the speech-language pathologist the option of using assessment activities which can be adapted to match the needs of the child being assessed. And finally, ideas for family-professional collaboration in the assessment of young children's language and literacy development are provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
