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…

This study examines the impact of High-Immersion Virtual Reality (HiVR) as a tool for teaching English L2 pragmatics to international students enrolled in an Intensive English Program at a US university. This research focuses on integrating HiVR into explicit L2 pragmatics instructional treatments. A quasi-experimental design was employed to…

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…

The purpose of this dissertation was to understand and compare the effect of training non-native English Speaking (NNES) learners (N = 480) in two distinct learning environments, (i) traditional face-to-face and (ii) online synchronous hybrid learning (SHL). In the traditional training mode, NNES learners (n = 360) were trained by NNES voice and…

Teacher beliefs have received substantial attention particularly in Chinese as a world language context due to the Chinese language proficiency challenges, Chinese character complexity, and cultural barriers. With the development of cutting-edge technology, Computer-Assisted Language Learning (CALL) has played a pivotal role in Chinese language…

Multilingual college students often struggle with writing and revising for academic purposes. This dissertation explored the effectiveness of a Concept-Based Language Instruction (C-BLI) approach to teaching revision processes to college-level multilingual writers. Although a significant body of research exists on effective feedback on…

This study investigates the effects of four online vocabulary tasks on second language (L2) vocabulary acquisition among learners of different proficiency levels. While tasks are widely used to support L2 vocabulary learning, the efficacy of a task depends on the interplay between task and learner factors. Thus, choosing an appropriate task…

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…

Early Expressive language exposure is associated with child language acquisition and advantageous long-term developmental outcomes. The measurement of expressive language in a child's immediate environment is critical to the early identification of children who are at risk of low expressive language exposure, such as children with language delays…

The strand of feedback research within the field of Instructed Second Language Acquisition (ISLA) examines the effects of feedback on the development of second language (L2) knowledge and learning behaviors. While findings often make claims about the relationship between feedback and language processing, much of this research has not measured…

Natural language is highly complex and can be challenging for some learners, yet the contribution of complexity to individual differences in language learning remains poorly understood. This poor understanding appears due to both a lack of consensus among researchers regarding what complexity is, and to on-line language research often employing…

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…

Research over the last two decades has shown middle school EBs are at risk for academic failure due to compounded systematic challenges that prevented them from acquiring reading proficiency level required to succeed in academic setting (Bowman-Perrott et al., 2010; Deussen et al., 2017; Sheng et al., 2011; Slama, 2012). EBs face shortages of…

The recent world pandemic has highlighted the need for effective procedures to teach language in Computer Assisted Language Learning (CALL) environments. Fully online and asynchronous classrooms are especially challenged when addressing learning to speak a foreign language toward greater communicative competence. Current CALL research is…

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…
