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…

The present study explored perceptual and articulatory techniques addressing the pronunciation of Spanish rhotics by means of a week-long computerized training. Through a quasi-experimental design approach, the study tested the utility of the online training and its effects on the phonetic production of taps [voiced alveolar tap or flap] and…

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…

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…

A common drawback in traditional language education is that all students in the same class use the same content. Since students may have different backgrounds such as prior knowledge and learning speed, one single curriculum may not be able to accommodate every student. Unfortunately, most students cannot afford personalized language learning,…

The study abroad (SA) context is often assumed to foster pragmatic development in a second language (L2), yet previous scholarship confirms that pragmatic norms are culturally-shaped and often remain imperceptible to uninstructed SA students (Bataller, 2010; Cohen & Shively, 2007; Shively, 2010). Because pragmatics is not traditionally taught…

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…

This study used a multiple probe design across participants to examine the effects of classroom simulation using static picture prompts to teach students to make a purchase using a debit card and track expenses by subtracting purchase amounts and adding deposits into a check register. Results demonstrated a functional relation between simulated…

As the growing popularity of podcasting and its application in education become more apparent, there have been a number of studies on the academic use of podcasts. A podcast is a digital file that can be delivered automatically to a device such as a portable media player or a computer via the Internet. However, the majority of research studied the…

For several decades, research in instructed second language acquisition (SLA) has focused on identifying the facilitative role that interaction plays in second language (L2) development (e.g., Gass, 1997; Long, 1996; Pica, 1996). Within this area of interest, a considerable amount of attention has been directed toward the feedback that learners…

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…

In this era of increased accountability in education, there is a need for tools to use in assessing the abilities and instructional levels of young children. Computers have been used successfully to assess older children and adults. However, there is a dearth of empirical research to provide evidence that computer-based testing (CBT) is…
