“…Emergent literacy skills such as phonological awareness and knowledge of orthographic symbols (letter name and sound knowledge) are essential to lexical-level literacy skills such as word reading and spelling development (National Early Literacy Panel, 2008;National Institute of Child Health and Human Development, 2000), and considered constrained skills because the amount of learning in these areas is finite (Snow & Matthews, 2016). In contrast, reading comprehension is a higher order skill that requires all the other skills (emergent literacy skills, word reading, reading fluency, oral language) as well as higher order cognitive skills such as inference, perspective taking, and comprehension monitoring; Barnes, Ahmed, Barth, & Francis, 2015;Cain, Oakhill, & Bryant, 2004;Cromley & Azevedo, 2007;Kim, 2017;Oakhill, Cain, & Bryant, 2003;Perfetti, Landi, & Oakhill, 2005). Therefore, improving reading comprehension requires concerted and sustained efforts to a greater extent compared to constrained skills such as emergent literacy skills.…”
