We examined the direct impact of an ongoing, intensive, and structured professional development (PD) within an English-as-second-language (ESL) instructional intervention on (a) teachers' time allocation in cognitive--academic language proficiency (CALP) and (b) Spanish-speaking English language learners' (ELLs) CALP development from the second to…

The purpose of the present paper is to introduce the Teachers' Choices Cognate Database. English-Spanish cognates are words that are orthographically and semantically identical or nearly identical in both English and Spanish. To create this free online database, the cognates from every one of the 146 International Reading Association's…

This longitudinal study examined the role of oral proficiency on English reading comprehension, as measured with elicited narratives using a wordless picture book, "Frog Where are You?". The sample consisted 102 English language learners, including both Spanish and Cantonese speakers. Narrative samples were collected in the winter of…

This dissertation project represents a 2.5-year ethnographic study in a second-grade bilingual classroom and the homes of seven emergent bilingual children of Mexican-origin. This study examines how educational assessment policies shape the ways in which emergent bilingual children are socialized to express social and academic identities during…

The present study investigated the role of vocabulary depth in reading comprehension among a diverse sample of monolingual and bilingual children in grades 2-4. Vocabulary depth was defined as including morphological awareness, awareness of semantic relations, and syntactic awareness. Two hundred ninety-four children from 3 schools in a…

The Working Memory Rating Scale (WMRS) was designed as a behavioral rating tool to assist teachers in identifying students at risk of working memory difficulties. The instrument was originally normed on 417 monolingual English-speaking children from the United Kingdom. The purpose of this study was to test the reliability and validity of the WMRS…

Young monolingual children typically demonstrate frequent tense shifting during narrative development, whereas older children maintain a consistent narration tense. Therefore, inconsistent tense usage in older children could be an indication of overall limited language skills. However, information regarding tense use in bilinguals has been…

This cohort-sequential study explored the components of working memory (WM) that underlie second language (L2) reading growth in 450 children at risk and not at risk for reading disabilities (RD) whose first language is Spanish. English language learners designated as balanced and nonbalanced bilinguals with and without risk for RD in Grades 1, 2,…

Although the research literature regarding language growth trajectories is burgeoning, the shape and direction of English Language Learners' (ELLs) language growth trajectories are largely not known. This study used growth curve modeling to determine the shape of ELLs' language growth trajectories across 12,248 oral narrative language samples…

This study examines vocabulary growth rates in first and second languages for Spanish-speaking and Cantonese-speaking English language learners from kindergarten through second grade. Growth-modeling results show a within-language effect of concepts about print on vocabulary. Language exposure also had an effect on English vocabulary: earlier…

This study investigates the relation between Spanish and English early literacy skills in kindergarten and first grade, and English oral reading fluency at the end of first and second grade in a sample of 150 Spanish-speaking English language learners. Students were assessed in kindergarten, first, and second grades on a broad bilingual academic…

Is it best to learn reading in two languages simultaneously or sequentially? We observed second- and third-grade children in two-way "dual-language learning contexts": (a) 50:50 or Simultaneous dual-language (two languages within same developmental period) and (b) 90:10 or Sequential dual-language (one language, followed gradually by the other).…

The present study investigated whether young Latino dual-language learners' 2-year English reading growth varied over time according to their initial overall oral English ability. We followed 41 Latino children for 2 years. We tested overall oral English at the beginning of the study and administered multiple curriculum-based reading assessments…

Many classrooms have interactive whiteboards and several computers and many schools are equipped with a computer lab and mobile labs. However, there typically are not enough computers for every student in each classroom; mobile labs are often shared between several members of a team and time in the computer labs needs to be scheduled in advance.…

This study examined the relationship between Spanish oral reading fluency (ORF) at the end of second grade and students' performance on the third grade ISAT reading test. The major research question guiding this study was: What is the direction and strength of the relationship between performance on the 2nd grade IDEL FLO, a Spanish language ORF…
