Great strides have been made in the development of effective methods of instruction for children with dyslexia. However, individual response to treatment varies, and weaknesses persist for some students with dyslexia despite otherwise effective instruction. Continued efforts are needed to support the prospective identification of poor response,…

This study examined the relations between and predictive power of three important subcomponents skills of reading comprehension: decoding, listening comprehension, and reading fluency. Through a series of structural equation models, we examine the relations within a full sample of first grade students at the beginning of the year (N = 290). Next,…

Although instruction has been shown to be effective at increasing vocabulary knowledge and comprehension, factors most important for promoting the acquisition of novel vocabulary are less known. In addition, few vocabulary studies have utilized models that simultaneously take into account child-level, word-level, and instructional factors to…

Many children with autism spectrum disorders (ASD) struggle with reading comprehension. Linguistic comprehension is an important predictor of reading comprehension, especially as children progress through elementary school and later grades.

Fluent readers can read connected text with accuracy, automaticity, and prosody. Without practice, automaticity cannot develop in reading, and readers must focus their attention on decoding, limiting their ability to simultaneously comprehend. Researchers have traditionally assumed that fluency and comprehension have a unidirectional relationship…

Studies investigating individual differences in reading ability often involve data sets containing a large number of collinear predictors and a small number of observations. In this article, we discuss the method of Random Forests and demonstrate its suitability for addressing the statistical concerns raised by such data sets. The method is…
