This dissertation uses the Conceptual Blending Hypothesis from the socio-cognitive method presented and refined by Kecskes (2002, 2004, 2007, 2010, 2020) to explain how the lexical choice of bilinguals differs across sociocultural situations. Quantitative (lexical density, lexical diversity, and lexical sophistication) and qualitative (lexical…

In an Eastern U.S. school district, little is understood about how elementary general education teachers apply instructional strategies for English Language Learners (ELLs) in the classroom and which strategies they perceive support academic achievement.

A growing number of studies has shown that collaborative writing tasks facilitate second language (L2) development by providing learners with opportunities to focus their attention on language and to collaborate in the solution of their language-related problems (e.g., Choi & Iwashita, 2016; Storch, 2013; Swain & Lapkin, 1998; Williams,…

English language learners need instructional strategies that could bridge the gap between them and native English speakers. The problem is that English language learners have limited English proficiency, and they could perform at a higher academic level when their teachers deliver effective instructional techniques. It is vital for teachers to…

This qualitative case study explores how five multilingual student writers (re)negotiate their multilingual literacies histories with emergent U.S. academic writing conventions as part of a first-year multilingual composition (FYMC) class. In pursuit of examining this (re)negotiation, first, I define multilingual literacies as nomadic (Ciolfi…

This study examines second language activation in Arabic-English bilinguals for whom Arabic was the first language. Modeling its design on Colome (2001), the research compared processing in a picture-phoneme matching task for Arabic-English bilinguals tested in the United States or in Saudi Arabia to determine whether activation of English…
