Cognitive predictors of word reading in Sinhala

We examined whether akshara knowledge, phonological awareness, phonological memory, and RAN predict variability in word and nonword reading skills in Grade 1–4 children (N?=?200) learning to read Sinhala. Hierarchical regression analyses showed that akshara knowledge had the strongest unique association with both word and nonword reading accuracy across grades. Akshara knowledge and RAN predicted word and nonword reading fluency. The impact of phonological memory and syllable awareness on reading was mostly mediated by akshara knowledge, and phoneme awareness was not uniquely associated with word reading skills in any grade. These results suggest that there are multiple cognitive correlates of accurate and fluent word reading in Sinhala, and akshara knowledge is the most important predictor of learning to read words. The findings have implications for the literacy acquisition, development, and instruction in alphasyllabaries.

     

Targeting phonological representations can help in the early stages of reading in a non‐dominant language

It is not known whether children who are struggling with reading in a non‐dominant language will respond better to a phonological intervention or to one that addresses oral proficiency. Multilingual seven‐to nine‐year‐olds showing reading difficulty in a non‐dominant language, English, were given a three‐week intervention in phonological skills or in language proficiency and were compared with two control groups (one with reading difficulties and one with no reading difficulties) who received a non‐language based intervention. The group receiving the explicit phonological instructions showed significantly better gain in reading and spelling measures than the language proficiency and reading difficulties control group, but did not reach the levels of the noreading‐difficulty group. The phonological intervention was particularly effective for children with the lowest single‐word reading scores. We suggest that the intervention helped to catalyse the fine‐tuning of the phonological domain, making phonological representations optimally available for decoding, phonological manipulations and literacy development.     

Instruction Matters to the Development of Phoneme Awareness and Its Relationship to Akshara Knowledge and Word Reading: Evidence from Sinhala

We examined whether global instruction of complex akshara and explicit phoneme-level instruction of akshara impact the development of phoneme awareness and its association with akshara knowledge and word reading accuracy. The participants were 100 Sinhala-speaking children from Grades 4 and 5 in Sri Lanka. Phoneme awareness showed stronger growth and a significant relationship with word reading accuracy and akshara knowledge only after children received explicit phoneme-level instruction in akshara construction. Both word reading accuracy and akshara knowledge predicted phoneme awareness, but the opposite was not true. The results suggest that phoneme awareness in Sinhala is sensitive to the method of reading instruction, and contrary to the studies in alphabetic languages, it does not have a bidirectional relationship with reading.

Classroom literacy practices in low- and middle-income countries: an interpretative synthesis of ethnographic studies

Surveys in low- and middle-income (LMI countries) reveal persistently low levels of learning among children in disadvantaged communities. Against this background, our synthesis of ethnographies aims at a fresh interpretation of classroom practices to clarify instruction-related barriers to literacy attainments. The review focuses on the period from 1990, the year of the UN Declaration of Education for All, to 2014. Sixteen studies focusing on children up to Grade 4 from eleven LMI countries met criteria for methodological rigour. The synthesis, structured within socio-cultural and psycholinguistic frameworks, examined vignettes of teacher- and child-initiated talk and activities related to language and literacy learning. Trends captured include instructions that are light on explanation, skewed towards reinforcing orthographic knowledge, and leaving the advancing of children’s broader linguistic and general knowledge to incidental learning. Learning from the peer group is common and, in bi- and multilingual settings, use of home language as a learning resource is uncommon. It is proposed that a cultural analysis of choral lessons, writing for learning, peer tutoring and community-specific preferences for language of instruction is required to understand whether embedding inference-focused interventions within these practices will promote more effective teaching and learning.
