Few of previous reading studies "comprehensively" examined the contributing factors of students' digital reading literacy. To fill this gap, based upon the ecological perspective, this study aims to investigate which factors from the student, home, and school context are more important in discriminating high-performing digital readers…

PIRLS (Progress in International Reading Literacy Study) is the fourth assessment in the current trend series, following PIRLS 2001, 2006, and 2011. There were 61 participants in PIRLS 2016, including 50 countries and 11 benchmarking entities (e.g., regions of countries as well as additional grades or language groups from the participating…

The purpose of this study was to explore the hypothesis that teaching students knowledge of word forms and meanings supports the development of decoding and linguistic comprehension, which are fundamental components of reading comprehension. We examined this hypothesis by investigating the effects of a comprehensive word knowledge intervention on…

The Internet has become the primary source for obtaining information at work, at home, and for school. Because Internet reading increasingly is becoming one of the central ways students are acquiring information, in 2016, the Progress in International Reading Literacy Study (PIRLS) was extended to include ePIRLS--an innovative assessment of online…

Modern behavior-genetic studies of twins in the United States, Australia, Scandinavia, and the United Kingdom show that genes account for most of the variance in children's reading ability by the end of the 1st year of formal reading instruction. Strong genetic influence continues across the grades, though the relevant genes vary for reading words…

Genetic and environmental relations between vocabulary and reading skills were explored longitudinally from preschool through Grades 2 and 4. At preschool there were strong shared-environment and weak genetic influences on both vocabulary and print knowledge but substantial differences in their source. Separation of etiology for vocabulary and…
