This study explores using transfer learning in machine learning for natural language processing (NLP) to create generic automated essay scoring (AES) models, providing instant online scoring for statewide writing assessments in K-12 education. The goal is to develop an instant online scorer that is generalizable to any prompt, addressing the…

Dialogue systems, commonly called as Chatbots, have gained escalating popularity in recent times due to their wide-spread applications in carrying out chit-chat conversations with users and accomplishing tasks as personal assistants. These systems are typically trained from manually-labeled data and/or written with handcrafted rules and often, use…

This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

This experimental study, and partial replication of Sun and Hu (2020), examined how and to what extent direct (i.e., hands-on corpus use) or indirect (i.e., hands-off corpus use) online data-driven learning (DDL) modules were able to assist Chinese writers from an English as a foreign language (EFL) context in using more appropriate hedging (i.e.,…

As critical approaches to Heritage Language (HL) instruction are increasingly more widespread, it is now more pertinent than ever to conduct research on Spanish linguistic variation that reveals systematicity and refutes hegemonic notions of 'incorrectness'. This variationist study examines the use and distribution of the Preterite and Imperfect…

In phonetics research, language alternation--including code switching (speaker-initiated) and cued switching (researcher-prompted)--can be used as a tool to investigate various aspects of speech production and perception in bilingual or multilingual speakers (Bullock & Toribio, 2009a). Studies on the production of voice onset time (VOT) during…

While information theory is typically considered in the context of modern computing and engineering, its core mathematical principles provide a potentially useful lens through which to consider human language. Like the artificial communication systems such principles were invented to describe, natural languages involve a sender and receiver, a…

Language on the Internet and social media varies due to time, geography, and social factors. For example, consider an online chat forum where people from different regions across the world interact. In such scenarios, it is important to track and detect regional variation in language. A person from the UK, who is in conversation with someone from…

This dissertation sheds light on how learners of German, NSs of German, and Americans unfamiliar with German reach decisions about the nature of speech acts that they witness NSs of German perform in three authentic video clips. It also aims to gain a better understanding of what sources members of the three groups bring to bear when they attempt…

Our language changes very rapidly, accompanying political, social and cultural trends, as well as the evolution of science and technology. The Internet, especially the social media, has accelerated this process of change. This poses a severe challenge for both human beings and natural language processing (NLP) systems, which usually only model a…

This study examines the frequency effect of two-word collocations involving "para" "to," "for" (e.g. "fui para," "para que") on the reduction of "para" to "pa" (in Spanish) and "pra" (in Portuguese). Collocation frequency effects demonstrate that language speakers…

Reentry Shock had been studied through psychological symptoms and inter-relationship problems. Previous research also focused on quantitative data of post-experience questionnaires. This dissertation examines how reentry support programs help students during the reentry process and how participants integrate the study abroad experience into their…

Reading aloud to students is an important topic in educational research. Previous research clearly identified effective components and benefits of reading aloud to elementary students; however, very little data addresses the exact wording of the kinds of questions teachers ask and the responses that students give during a read aloud. This study…

As digital media practices become readily available in today's classrooms, literacy and literacy instruction are changing in profound ways (Alvermann, 2010). Professional organizations emphasize the importance of integrating new literacies (New London Group, 1996) practices into language-arts instruction (IRA, 2009; NCTE, 2005). As a result,…

The current government in Korea, in order to encourage more fluent use of English, has shifted the focus of the English curriculum from language accuracy to language fluency by encouraging English teachers to use English as a classroom language. However, many English teachers in Korea feel burdened by this policy, mainly because they themselves…
