Naturalistic language learning is contextually grounded. When people learn their first (L1) and often their second (L2) language, they do so in various contexts. In this dissertation I examine the effect of various contexts on language development. Part 1 describes the effects of textual, linguistic context in reading. I employed an eye-tracking…

This doctoral dissertation explores diverse facets of online research and comprehension among college students with English as a second or foreign language (L2 students). The research involves three distinct investigations within this overarching theme. Firstly, the study delves into the online reading and writing practices employed by Korean L2…

In the field of Instructed Second Language Acquisition (ISLA), written corrective feedback (WCF) has been shown to play a facilitative role in improving written accuracy (e.g., Ashwell, 2000; Ferris & Roberts, 2001; Ferris, 2006; Sheen, 2007; Bitchener, 2008; Liu & Brown, 2015). However, studies that examine the effects of different types…

There is an ongoing debate as to whether written corrective feedback (WCF) is effective for the improvement of adult second language (L2) writers' accuracy. Ever since Truscott (1996, 1999) began arguing against grammar correction in L2 writing courses, researchers have challenged his position (i.e. below). Although most of these studies show WCF…

Rater variation in performance assessment can impact test-takers' scores and compromise assessments' fairness and validity (Crooks, Kane, & Cohen, 1996). Rater variation can also undermine a test's validity and fairness; therefore, it is important to investigate raters' scoring patterns in order to inform rater training. Substantial work has…

This dissertation explores seven second language (L2) undergraduates' learning experiences in a First-Year Writing (FYW) course at an American university. While the FYW course is designed from the perspective of first-language (L1) composition scholarship and focuses, broadly speaking, on analytical writing and the related development of critical…

The field of game-mediated L2 learning has grown exponentially, and much has been discovered about the potentials of game-mediated interactions for L2 development, yet the fine-grained dynamics of player-game interactions and how they come to facilitate and afford L2 development are still largely underexplored. To address this gap in the…

The field of Instructed Second Language Acquisition (ISLA) has expressed interest in pursuing a research agenda that expands the current heritage language (HL) strand of research to investigate how this heterogeneous population re-learns their family language, and how this experience differs from that of second language (L2) learners. This…

International students, a growing population in US universities, need to possess excellent reading skills in order to succeed. American universities also benefit from admitting students who do not require remedial English classes. Reading online has become an integrated part of college education, which requires students to have additional skills.…

While attentional models of SLA postulate attention as crucial for learning to take place (e.g., Robinson, 1995b; Schmidt, 1990, 2001; Tomlin & Villa, 1994), the role that awareness or lack thereof plays remains debatable. Indeed, the studies that have empirically addressed the construct of unawareness reveal conflicting results (e.g.,…

Reading comprehension of school-aged students is an important topic of research; however, research on the reading comprehension of adult foreign/second language learners whose first language is English is limited, especially studies investigating the reading comprehension strategies that readers of different proficiency levels use when they…

Since the mid-1990s, the link between recasts and L2 development has been extensively tested, and the results from those studies have largely demonstrated that recasts have a positive effect on L2 learning. With this firm support from previous empirical evidence, studies have begun to focus on how recasts assist learning and under what conditions…

The purpose of this study is to explore ways of incorporating web-based concordancers for the purpose of teaching English collocations. A mixed-methods design utilizing a case study strategy was employed to uncover four specific dimensions of corpus use by twenty-four students in two classroom sections of a writing course at a university in…

Effective listening comprehension skills are important as the world becomes increasingly global and television, radio, and the Internet become forums for English communication. However, many countries, such as Tunisia, do not use English as a first or second language, but as a foreign language. Therefore, realizing the importance of English, the…

This dissertation tests a grammatical structure, differential object marking (DOM), which is particularly difficult for L2 learners to acquire. DOM is a phenomenon in which some direct objects are morphologically marked to distinguish them from subjects (Comrie, 1979). In Spanish, animate and specific direct objects are marked with the preposition…
