Vocabulary use across genres: implications for students with complex communication needs.

PURPOSE: This study examined the vocabulary words and multiword sequences used by 124 typically developing kindergarten and 1st-grade students when they wrote about self-selected topics. The study extends previous research by examining the vocabulary used in different genres. METHOD: A total of 457 writing samples were analyzed. The samples were classified according to 9 genres and were analyzed using the Child Language Analysis ( MacWhinney, 2006) software program. RESULTS: The authors found that 140 words represented 70% of the vocabulary produced. The most common genre types were narrative recounts and opinions. The patterns of frequency for words and multiword sequences varied across genres. The degree of variation was greater for particular vocabulary words. For instance, the word going was used predominantly in 1 genre. In contrast, the word mom was used in every genre except 3. The structure words tended to be used with high frequency across genres. CONCLUSION: The word lists generated can be used to inform vocabulary selection, organization, and instruction for students with complex communication needs who are beginning writers.

Words needed for sharing a story: implications for vocabulary selection in augmentative and alternative communication.

BACKGROUND: This study examined the narrative vocabulary of typically developing children for the purpose of guiding vocabulary selection for children with complex communication needs. METHOD: Eight children in their first year of schooling (aged 5 years 0 months to 5 years 8 months) and 10 children in their second year of schooling (aged 6 years 0 months to 7 years 2 months) generated story retell, personal, and script narratives. These were analysed using the Child Language Analysis (MacWhinney, 2008 ) program. RESULTS: Several words occurred with high frequency across all tasks. Other words were more specific to particular tasks and topics. In the story-retelling task, the majority of the unique words used were from the original story. However, of the total words available in the original story, only a small proportion was used. CONCLUSIONS: Some of the high frequency words overlapped with those included in existing wordlists. However, other words were unique to this study. The wordlists generated will provide a useful resource that can be used alongside existing wordlists to guide decision making around vocabulary selection for children with complex communication needs.

The vocabulary of beginning writers: implications for children with complex communication needs.

One of the greatest challenges facing augmentative and alternative communication (AAC) professionals is providing children with complex communication needs with access to the vocabulary that they need in order to develop mature language and literacy abilities. The purpose of this study was to analyze the vocabulary used by typically developing early-elementary children in the United States and New Zealand when they write about self-selected topics, in order to inform practices with children with complex communication needs. The children's writing samples were compared across school ages and countries. The school age comparisons highlighted the relatively restricted range of vocabulary used by children in the earliest stages of writing development, and the country comparisons revealed differences in core vocabulary. The findings of this study hopefully will assist AAC professionals as they engage in selecting, prioritizing, and organizing vocabulary to support written language development in children with complex communication needs.

Automatic word recognition: the validity of a universally accessible assessment task.

In the current study, the validity of a task designed to assess the automatic word recognition skills of persons with complex communication needs was investigated. A total of 78 students without communication impairments in kindergarten through second grade completed a standard automatic word recognition task requiring oral reading of words presented for less than 0.25 s. The same students completed an experimental word recognition task that did not require a spoken response. Results support the validity of the experimental task. For example, the mean performance scores on both tasks decreased in the expected direction, and there was a significant correlation between the standard and experimental tasks. Other results suggest that the same trait was being measured by both tasks. The data highlight directions for future research and development of the experimental task, while leaving us enthusiastic about the future of the experimental task as a valid means of assessing automatic word recognition for persons with complex communication needs.
