An aim of research on bilingualism is to understand how the brain adapts to the use of more than one language. Although several important discoveries and insights about the consequences of bilingualism have been generated over the last several decades, concerns about replicability have narrowed the scope of inquiry and discussion to the…

The purpose of this study was to investigate if differences in perceived professional self-efficacy were due to various demographic characteristics for educators in a rural East Texas school district. Participants in this study were full-time teachers within the school district. The district consists of 2 elementary schools, 1 middle school, and 1…

Previous literature has shown that voicing contrast is a difficult feature for Chinese-English emergent bilingual learners of L3 Spanish (Bravo Diaz, 2020; Chen, 2007; Zhang, 2022). The production of voicing contrast in stops has been broadly investigated in second and third language studies (e.g., Zampini, 1998; Llama, 2010; Wrembel, 2014), but…

The purpose of this qualitative descriptive research study was to explore and describe how non-LDS full-time faculty and staff describe working and living in a predominately Church of Jesus Christ of Latter-day Saints (LDS) environment and whether the environment informs their social identity in the workplace at a public regional comprehensive…

Individual differences factors (IDs) play significant roles in second language (L2) learning. Compared to the general field of SLA, however, little is known in the L2 writing domain regarding the influence of learner factors in L2 writing achievement. Therefore, in this study, I aimed to extend the IDs research in L2 writing by closely examining…

Over time, state testing has been the central focus of schools and school districts regarding accountability and the pressures to improve student achievement (Dufour, 2004). Under those circumstances, professional learning communities have been discovered to improve teacher effectiveness which in turn improves overall student achievement (Kuh,…

Guided by Dynamic Systems Theory (DST) and multidimensional perspectives on individual differences (IDs) in instructed second language (L2) learning (e.g., Larsen-Freeman, 2014; Sun & Zhang, 2020), this longitudinal mixed-methods study focuses on three conceptually different categories of L2 learners' IDs: working memory (WM), motivation, and…

Mandarin Chinese verbs are composed of one to four characters that function together as a conceptual unit. However, in modern spoken Chinese, most of these verbs are two-character compounds. This dissertation is focused on adult second language (L2) learners' acquisition of these two-character verb compounds. Specifically, the acquisition of a…

Readers read for different purposes and the texts they read vary in topic and difficulty. These situational factors influence standards of coherence--how much understanding a reader aims to have for a given text. Three studies examined whether individual differences in reader-based standards of coherence influenced off-line and on-line…

This study proposed to investigate the financial aid literacy of college students and if differences existed between specific groups. The research examined a causal comparison between students who attended a convocation and who did not, Pell awarded student status, and first-generation college student status. The participants included 58 students…

American colleges and universities are agents of individual progress, social change and upward mobility that foster an educated citizenry and a prosperous economic system. The long-term benefits of earning a bachelor's degree are multiple, significant and well documented for graduates, their families and for the public at large. The notion of the…

Although a number of studies have been conducted to explore how various individual difference (ID) factors such as aptitude, motivation, and anxiety contributing to L2 learners' speech performance over a period of time of L2 learning, only a few examined the effect of the three ID factors on learners' L2 speech performances based on classroom…

The recent changes in global student mobility on U.S. higher education campuses call for increased attention to international student recruitment and retention. One of the approaches that universities can adopt in response to these changes involves addressing career-related concerns that are among those of most significance to international…

School psychologists use intelligence and academic achievement test scores to understand individual differences in abilities that may be directed towards learning and the learning that has already occurred. To make ethical and effective decisions regarding individualized educational programs and interventions, test users must understand the…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…
