The current study explores the contributions of written vocabulary and syntax to informational writing quality in Grades 5 through 8. Various aspects of language skills (receptive to written, oral register to academic register) have differing relationships with narrative and informational writing achievement across development. In this study, we…

This investigation examined the structural relations among latent variables of language, decoding, and reading comprehension, invariance of the patterns of predictions, and unique and common variance over two years in grade cohorts 5 to 6, 7 to 8, and 9 to 10. Participants were 321 students in grade 5 in six elementary schools, 299 students in…

In Study 1, children in grades 4-9 (N = 88, 29 females and 59 males) with persisting reading and/or writing disabilities, despite considerable prior specialized instruction in and out of school, were given an evidence-based comprehensive assessment battery at the university while parents completed questionnaires regarding past and current history…

Two measures of syntactic complexity, clauses per T-unit and words per clause, were used to examine differences among four genres of text--narrative, descriptive, compare/contrast, and persuasive--written by the same two cohorts (83 students in grades three and five and 96 students in grades five and seven) on two occasions 2 years apart as part…

Reading comprehension is a multi-dimensional process that includes the reader, the text, and factors associated with the activity of reading. Most research and theories of comprehension are based primarily on research conducted with monolingual English speakers (L1). The present study was designed to investigate the cognitive and linguistic…

This study examined the relationship of different measures of syntactic complexity with rated quality for two genres of text produced by middle school students. It was hypothesized that different measures would be associated with distinct aspects of syntactic complexity; words per clause with greater use of structures more typical of expository…
