In the ever-changing digital era, the surge of online informal language learning platforms has revolutionized the way we learn new languages. This dissertation delves into the critical role of interactional feedback (IF) in synchronous computer-mediated communication (SCMC), a cornerstone for optimizing these digital learning spaces. Anchored in…

The ability to speak in a second language (L2) requires a certain level of linguistic proficiency, but the ability to "live" in a second language requires a certain level of "sociolinguistic" proficiency. L2 sociolinguistic variables present acquisitional challenges for language learners, since informal discourse features are…

Second language (L2) learners often have difficulty perceiving L2 sound contrasts when the first-language (L1) and L2 sounds are acoustically similar and these similar L2 sounds correspond to an existing L1 sound (Flege, 1995). To improve L2 learners' perception of sound contrasts, researchers have used high-variability phonetic training (HVPT)…

Foreign language placement testing, an important component in university foreign language programs, has received considerable, but not copious, attention over the years in second language (L2) testing research (Norris, 2004), and it has been mostly concentrated on L2 English. In contrast to validation research on L2 English placement testing, the…

Self-regulation, an increasingly focus of social-emotional learning curriculums for over twenty years according to Zimmerman (2008), provides students with the ability of "setting goals, selecting strategies, and self-monitoring their effectiveness" as opposed to waiting for others to redirect their behavior (p. 166). Prekindergarten…

The present study contributes to our understanding of the effects of age and type of linguistic input in the acquisition of Spanish as a second language in adulthood. I examine the Spanish syntax (word order) of three groups of speakers, monolingual Spanish speakers from Mexico and two bilingual English-Spanish speakers born and raised in the…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…

Language is inherently variable, and learner language is particularly variable. The variationist paradigm considers learner language a heterogeneously variable yet inherently rule-governed system. Specifically, learners' alternation between native-like and nonnative-like variants of a variable or invariable target native speaker (NS) form…

Nonverbal behavior is essential in human interaction (Gullberg, de Bot, & Volterra, 2008; McNeill, 1992, 2005). For second language speakers, nonverbal features can be helpful for successful and efficient communication (e.g., Dahl & Ludvigsen, 2014). However, due to the complexity of nonverbal features, language testing institutions have…

With the recent surge of online language learning, it is important to explore the different possible modalities of online learning and the factors that could influence the success of those modalities in language learning. This study found differences in (1) motivation, (2) anxiety, (3) perception of the learning community, and (4) oral proficiency…

Purpose: The purpose of this quantitative, causal-comparative study was to determine whether English learners who participated in transitional kindergarten perform equally or better than English learners who did not participate in transitional kindergarten in the areas of oral language, written language, and overall language as measured by the…

Despite an emphasis on oral communication in most foreign language classrooms, the resource-intensive nature (i.e. time and manpower) of speaking tests hinder regular oral assessments. A possible solution is the development of a (semi-) automated scoring system. When it is used in conjunction with human raters, the consistency of computers can…

Practice is necessary for developing oral English proficiency, but many Chinese learners of English lack the self-confidence to practice oral English; furthermore, students' self-confidence deficiency is perpetuated by insufficient oral English proficiency. The purpose of this qualitative case study was to discover pedagogical practices that break…

It has long been recognized that collocations, or chunks of formulaic language, are essential and frequent in language (Henriksen, 2012; Sinclair, 2004). Therefore they are a crucial part of Second Language Acquisition (SLA). Linguistic scholars Pawley y Syder (1983: 192) remark that "in order to know a language, the [second language] (L2)…

The disproportionality of culturally and linguistically diverse learners in exceptional education is an ongoing issue (Bernal, 2002; Ford, 2012). One of these special populations is that of English learners (ELs), who are overrepresented in special education programs and underrepresented in gifted and talented programs (Ford, 2012).The extant…
