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…

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,…

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…

This mixed methods classroom research examined if accountability groups in the lower proficiency levels of a university intensive English program would improve students' language acquisition. Students were assigned partners for the study period with whom they completed assignments inside and outside of class, as well as set goals for use of…

This study analyzed how six Heritage language learners at the university level gained conscious awareness and control of the concept of modality as revealed in student verbalizations (Vygotsky, 1998) throughout five different written communicative events.

Although researchers have begun to explore the implementation of dynamic assessment (DA) with foreign language learners, few of these studies have occurred in the language classroom. Whereas DA is typically implemented in dyads, promising research in the field of foreign language learning suggests that DA may promote development with groups of…
