This study examined (a) the identification of various reading groups across languages in Chinese (L1) adolescents learning English as a second language (ESL), in terms of their word-reading and reading comprehension skills, (b) overlap in reading group membership across languages, and (c) the performance of the various reading groups on…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program designed to develop upper-elementary students' vocabulary skills in order to improve reading comprehension. The study used a true, group-randomized, experimental design, which randomly assigned 46 4th grade classrooms (n=1324 students) from 12 districts…

We assessed the simple view of reading as a framework for Grade 3 reading comprehension in two ways. We first confirmed that a structural equation model in which word recognition, listening comprehension, and reading comprehension were assessed by multiple measures to inform each latent construct provided an adequate fit to this model in Grade 3.…

This study investigated how middle school students leverage information about bound Latin roots (e.g., "voc" in "advocate" and "vociferous") to infer meanings of unfamiliar words, and how instruction may facilitate morphological analysis using roots. A dynamic assessment of morphological analysis was administered to…

A dynamic assessment of morphological analysis was administered to 29 sixth…

The present study used a randomized control trial to examine the effects of a widely used multicomponent Tier 2-type intervention, Passport to Literacy, on the reading ability of 221 fourth graders who initially scored at or below the 30th percentile in reading comprehension. Intervention was provided by research staff to groups of 4-7 students…

This study explored effects of Spanish oral language skills (vocabulary and syntax) on the development of English oral language skills (vocabulary, morphology, semantics, syntax) and reading comprehension among 156 bilingual Latino children in second through fifth grade whose first language was Spanish and whose second language was English. Using…

This dissertation is comprised of two manuscripts that resulted from a single study using verbal protocols to examine the reading processes prompted by the graphics as second graders read informational text. Verbal protocols have provided researchers with an understanding of the processes readers use as they read. Little is known, however, about…
