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…

The acquisition of a new morphological rule can be influenced by numerous factors, including the type of feedback provided during learning. The present study aimed to test the effect of different feedback types on children's ability to learn and generalize an artificial morphological rule (AMR). Two groups of eight-year-olds learned to judge and…

Linking research on task-based collaborative L2 writing and computer-mediated writing, this study investigates the relationship between patterns of collaboration and the linguistic features of texts written during a computer-supported collaborative writing task using Google Docs. Qualitative analyses provide insights into the writing process of…

Aim/Purpose: Using Artificial Intelligence with Deep Learning (DL) techniques, which mimic the action of the brain, to improve a student's grammar learning process. Finding the subject of a sentence using DL, and learning, by way of this computer field, to analyze human learning processes and mistakes. In addition, showing Artificial Intelligence…

This study contributes to the literature on second language (L2) learners' revision behavior by describing what, when, and how often L2 learners revise their texts when responding to timed writing tasks on the computer and by examining the effects of task type, L2 proficiency, and keyboarding skills on what and when L2 learners revise. Each of 54…

In English, positions of lexical stress in disyllabic words are associated with word categories; that is, nouns tend to be stressed more often on the first syllable, whereas verbs are more likely to be stressed on the second syllable (i.e. "sub"ject (noun) vs. sub"ject" (verb)). This phenomenon, which is called the stress…

Drawing on Vygotskian sociocultural theory of mind and social constructivism, and adopting a sequential exploratory mixed-methods approach, this study explored the impact of online dynamic assessment (DA) on EFL learners' academic writing skills through one-on-one individual and online synchronous DA sessions over Google Docs. It also investigated…

This study extends research on written corrective feedback (CF) by investigating how timing of CF affects grammar acquisition. Specifically, it examined the relative effects of synchronous and asynchronous CF on the accurate use of the hypothetical conditional structure. Participants were 68 intermediate-level students of English at a university…

This study examines the effect of recognition-based retrieval practice on vocabulary learning in a university Chinese class. Students (N=26) were given practice retrieving new vocabulary (single or two-character words) in a series of simple form recognition tests administered over four weeks. The test sets consisted of target vocabulary that…

The "e-rater"® automated essay scoring system is used operationally in the scoring of the argument and issue tasks that form the Analytical Writing measure of the "GRE"® General Test. For each of these tasks, this study explored the value added of reporting 4 trait scores for each of these 2 tasks over the total e-rater score.…

Voxy, an English-language-learning company, has developed a custom, in-house proficiency exam, the Voxy Proficiency Assessment (VPA), which is given to all learners at the beginning and end of their courses. Using Multinomial Logistic Regression (MLR), the impact of covariates, such as total learning activities completed and total number of…

Previous research on synchronous computer-mediated communication (SCMC) has shown that SCMC interaction could draw learners' attention to form in ways that are similar to face-to-face interaction. However, the role of task type in focusing learners' attention on form has not been widely researched. In a repeated-measures design, this study…

This study explores the relationship between scrolling, negotiated interaction, and self-initiated self-repair (SISR) in a task-based synchronous computer-mediated communication (SCMC) foreign language learning environment. Pairs of adult learners of German engaged in four jigsaw tasks over the course of one university semester. Video screen…
