Untangling the effects of shared book reading: Multiple factors and their associations with preschool literacy outcomes

Evidence strongly suggests that shared book reading at home and in preschool is important for young children's development of the foundational skills required for the eventual mastery of decoding and comprehension. Yet the nuances of how learning from book reading might vary across these contexts and with children's skills are not well understood. One hundred and thirty children participating in a longitudinal investigation of literacy development were videotaped reading a storybook with a parent. Children were also videotaped in their 33 preschool classrooms during the instructional book-reading portion of the day. Readings were coded for adult and child contextualized and decontextualized language relating to both decoding and meaning-making skills, and relations between this talk and emergent literacy outcomes were analyzed. Results demonstrate that parents and teachers overwhelmingly focus their book-related talk on meaning-related rather than code-related information, and that the relations between outcomes and talk depend in part on children's initial levels of vocabulary skills. Implications for practice and research are discussed.     

Variability in children’s early reading strategies

The present study examines the development of sight word reading in young children by examining changes in their self‐reported reading strategies over time. A sample of 65 five to seven year olds were asked to read 40 real word items, all carefully matched for letter length and word frequency, on three separate occasions. Changes in the children’s word identifications were measured using immediately retrospective verbal self‐reports. Overall, the results showed some variability in the children’s self‐reported reading strategies. Over time the children relied less on phonological strategies and moved towards reliance on directly retrieving words from memory. This change was most evident in the older children; while both year groups showed similar patterns of shifting reliance from explicit phonological strategies to retrieval, this shift was simply less frequent among the younger children. An analysis of word‐specific changes in reading strategies showed that the older children had a better sight vocabulary for more complex word items. These findings provide further support for Ehri’s mediated phase theory in explaining children’s development in learning to read.     

Txt msg n school literacy: does texting and knowledge of text abbreviations adversely affect children's literacy attainment?

This paper reports on two studies which investigated the relationship between children's texting behaviour, their knowledge of text abbreviations and their school attainment in written language skills. In Study One, 11–12‐year‐old children provided information on their texting behaviour. They were also asked to translate a standard English sentence into a text message and vice versa. The children's standardised verbal and non‐verbal reasoning scores were also obtained. Children who used their mobiles to send three or more text messages a day had significantly lower scores than children who sent none. However, the children who, when asked to write a text message, showed greater use of text abbreviations (‘textisms’) tended to have better performance on a measure of verbal reasoning ability, which is highly associated with Key Stage 2 (KS2) and 3 English scores. In Study Two, children's performance on writing measures was examined more specifically. Ten to eleven‐year‐old children were asked to complete another English to text message translation exercise. Spelling proficiency was also assessed, and KS2 Writing scores were obtained. Positive correlations between spelling ability and performance on the translation exercise were found, and group‐based comparisons based on the children's writing scores also showed that good writing attainment was associated with greater use of textisms, although the direction of this association is nor clear. Overall, these findings suggest that children's knowledge of textisms is not associated with poor written language outcomes for children in this age range.
