The Role of the Home Learning Environment on Early Cognitive and Non-Cognitive Outcomes in Math and Reading

The home learning environment (HLE) has been considered to contribute to children’s early math and reading development. Previous studies examined the HLE by examining the influence of parent-child math and reading activities on math and reading outcomes, however also parents’ own perceptions of math and reading and their math anxiety (MA) and reading anxiety (RA) contribute to the HLE but the latter factors have been scarcely explored. The aim of this study was to provide a more holistic view of the HLE and its relations with children’s cognitive and non-cognitive outcomes in math and reading at the start of primary school. This paper examined the relations within the HLE, and the relations between the HLE and children’s early math and reading outcomes. Participants were 301 first-grade children and their parents. The HLE was measured by the parent questionnaire. Children’s digit comparison, number line estimation, letter knowledge and phonological awareness skills were measured as well as their math and reading anxiety levels. The results demonstrated a significant association between parents’ perceptions and their anxiety towards math and reading. No significant associations were found between parents’ perceptions towards math and the frequency of home numeracy activities, whereas significant relations were found in the domain of reading. Socioeconomic status was found to provide a unique contribution in children’s digit comparison and math anxiety, while no significant relations were observed between other HLE factors and children’s outcomes. The current study suggests the importance of including parents’ perceptions and feelings to explore the dynamics of the HLE and its impact on children’s math and reading outcomes.

Developmental Trajectories of Letter and Speech Sound Integration During Reading Acquisition

Reading acquisition in alphabetic languages starts with learning the associations between speech sounds and letters. This learning process is related to crucial developmental changes of brain regions that serve visual, auditory, multisensory integration, and higher cognitive processes. Here, we studied the development of audiovisual processing and integration of letter-speech sound pairs with an audiovisual target detection functional MRI paradigm. Using a longitudinal approach, we tested children with varying reading outcomes before the start of reading acquisition (T1, 6.5 yo), in first grade (T2, 7.5 yo), and in second grade (T3, 8.5 yo). Early audiovisual integration effects were characterized by higher activation for incongruent than congruent letter-speech sound pairs in the inferior frontal gyrus and ventral occipitotemporal cortex. Audiovisual processing in the left superior temporal gyrus significantly increased from the prereading (T1) to early reading stages (T2, T3). Region of interest analyses revealed that activation in left superior temporal gyrus (STG), inferior frontal gyrus and ventral occipitotemporal cortex increased in children with typical reading fluency skills, while poor readers did not show the same development in these regions. The incongruency effect bilaterally in parts of the STG and insular cortex at T1 was significantly associated with reading fluency skills at T3. These findings provide new insights into the development of the brain circuitry involved in audiovisual processing of letters, the building blocks of words, and reveal early markers of audiovisual integration that may be predictive of reading outcomes.

Current State of the Evidence: Examining the Effects of Orton-Gillingham Reading Interventions for Students with or at Risk for Word-level Reading Disabilities

Over the past decade, parent advocacy groups led a grass-roots movement resulting in most states adopting dyslexia-specific legislation, with many states mandating the use of the Orton-Gillingham approach to reading instruction. Orton-Gillingham is a direct, explicit, multisensory, structured, sequential, diagnostic, and prescriptive approach to reading for students with or at-risk for world-level reading disabilities (WLRD). Evidence from a prior synthesis (Ritchey & Goeke, 2006) and What Works Clearinghouse reports (WWC, 2010) yielded findings lacking support for the effectiveness of Orton-Gillingham interventions. We conducted a meta-analysis to examine the effects of Orton-Gillingham reading interventions on the reading outcomes of students with or at risk for WLRD. Findings suggested Orton-Gillingham reading interventions do not statistically significantly improve foundational skill outcomes (i.e., phonological awareness, phonics, fluency, spelling; ES = 0.22, p = .40); though the mean effect size was positive in favor of Orton-Gillingham-based approaches. Similarly, there were not significant differences for vocabulary and comprehension outcomes (ES = 0.14; p = .59) for students with or at-risk for WLRD. More high quality, rigorous research with larger samples of students with WLRD is needed to fully understand the effects of Orton-Gillingham interventions on the reading outcomes for this population.
