The present study sought to evaluate trial designs and training designs that are commonly used in popular commercially available computer-assisted language-learning (CALL) programs. The first two experiments (Experiment 1a and 1b) compared the effects of passive viewing and active student response methods in vocabulary learning. Contingencies on…

This study investigates the neurocognitive underpinnings of early language learning in adults and examines the modulating effects of individual differences in prior bilingual experience and cognitive capabilities. This study used a pre/post short-term longitudinal design with a 10-day Dutch language training via Rosetta Stone. Event-Related…

Automated corrective feedback (ACF), in which a computer system helps language learners identify and correct errors in their writing or speech, is considered an important tool for language instruction by many researchers. Such systems allow learners to correct their own mistakes, thereby reducing teacher workload and potentially preventing issues…

Second language learners constitute a significant and expanding portion of the global population and there is a growing demand for tools that facilitate language learning and instruction across various levels and in different countries. The development of large language models (LLMs) has brought about a significant impact on the domains of natural…

The digital transformation in educational assessment has led to the proliferation of large-scale data, offering unprecedented opportunities to enhance language learning, and testing through machine learning (ML) techniques. Drawing on the extensive data generated by online English language assessments, this dissertation investigates the efficacy…

During the last 60 years, the United States (US) has experienced a rapid growth of MLLs (multilingual learners), also known as ELLs (English Language Learners) or English as a Second Language (ESL) learners. These students represent a large segment of the public education population, and there is an academic achievement gap between MLLs and…

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…

A number of studies in mobile learning research have shown that the use of computer-assisted language learning (CALL) and many different types of technology within language learning contexts can potentially influence learning of students, particularly the younger generation. In the current study, two participant groups -- EFL teachers and parents…

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.,…

In recent decades, a plethora of empirical work has indicated that collaborative writing (CW) affords more opportunities for collective scaffolding and language negotiation (Li & Kim, 2016; Li & Zhu, 2013; Storch, 2019) and promotes the development of second language (L2) writing skills (Bikowski &Vithanage, 2016; Storch, 2013; Strobl,…

This dissertation presents four iterative experiments which explore the quantitative benefits of introducing linguistics to language learners. Previous work has connected exploration of linguistic with improved morale and engagement in language classrooms, as well as reduced language discrimination and validation of students' languages and…

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…

Quasi-experimental research was conducted to examine the effect of game-based student response systems (GBSRS) on student achievement and self-efficacy in languages other than English (LOTE). The research employed a pretest-posttest, non-equivalent control group design in which 170 third and fourth-grade students participated in a 12-session…

The purpose of this design-based research study was to provide a holistic perspective on the pedagogical and contextual factors of interactive mobile technology on English learners and investigate the theoretical potential of audio-video software interventions for second language acquisition. Specifically, the study explored current virtual…

The present project is a research-based and practice-tested online synchronous curriculum for English language learners with the Russian language mother tongue. The curriculum's theoretical component is grounded in Vygotsky's, Leont'ev', and Engestrom's "Cultural Historical Activity Theory" as well as in scholarly papers on the influence…
