As the 21st century unfolds, the world has become increasingly fast-paced, interconnected and unpredictable compared to previous generations (McChrystal, et al., 2015). As a result, education researchers and practitioners must be prepared for the challenge of helping students better apply their knowledge to respond to the complex and novel…

American K-12 public teachers are leaving the field of education in record numbers. This lack of teacher retention negatively impacts student achievement. Teacher turnover intentions have been found to be an indication of potential attrition. Research on brain-based learning reveals new opportunities to decrease teacher turnover intentions by…

This dissertation investigates the interplay between the implicit knowledge that learners have of a nonnative language and their processing of that language, examining two types of relative clauses (RCs) in English: gapped RCs (e.g., "the man that they hired") and resumptive RCs (e.g., *"the man that they hired him").…

Reading comprehension is a critical academic skill that permeates all academic subjects. Students with autism spectrum disorder are more likely to struggle with reading comprehension, especially as they enter secondary education. Therefore, evidence-based interventions to support middle school students with autism in developing reading…

This dissertation investigates the interaction of developing extralinguistic cognitive systems with early language learning and processing through the case study of verb argument structure. The interaction of these systems with the linguistic system underpins fundamental theories of language learning and use: language does not exist in isolation.…

The role of the right hemisphere in phonetic processing is thought to be relatively minimal, at least in comparison to the role of the left hemisphere. However, the right hemisphere is known to play a critical role in vocal identity processing, a fact that is striking given that the acoustic-phonetic details of the speech signal can differ…

The purpose of this phenomenological study was to explore teachers' lived experiences with student engagement in classrooms with a predominantly Hispanic population. According to the data collected in this study, academic engagement is often characterized in terms of observable behavior. However, research has proven that student engagement is a…

Mathematical definitions are central to learning and doing mathematics. Research has uncovered significant differences between how mathematicians and non-mathematicians construct, reason about, and refine mathematical definitions. Various strands of research provide insight into the development of definitional practices, yet an integrated approach…

Usage-based Phonology proposes that language users' knowledge is stored in the form of exemplars reflecting experience of language usage. Exemplars encompass all visual and auditory information perceived during a language interaction, but few studies have examined the role that visual information plays. This dissertation addresses this question…

Within the field of school psychology, the currently accepted structure of intelligence is the Cattell-Horn-Carroll Model (CHC). The CHC model contains three strata of abilities: a general ability (g), multiple broad cognitive abilities, and several narrow abilities (Schneider & McGrew, 2018), although the theoretical salience of the g factor…

The purpose of this non-experimental, comparative quantitative study was to determine if there were significant differences between the perceptions of undergraduate and graduate students about the importance and presence of sense of community in online classes at two southern public universities using survey data. The study also aimed to determine…

Instructional design in a fire academy is essential for high academic achievement while students learn the basics of firefighting and hazardous materials. It is critical to explore concerns about balancing the students' cognitive load because of a significant decline in academic achievement. Students pursuing a firefighting career at a community…

A pervasive and widespread shortage of early intervention (EI) teachers is preventing vital services from reaching infants and toddlers with disabilities during their most critical period of brain development. To better understand the EI teacher shortage, this qualitative study examined the career decision-making of 11 EI teachers from the…

This study investigated middle school students' Artificial Intelligence (AI) literacy, focusing on cognitive and affective dimensions with regard to learning about AI. Fourteen middle school students participated in a five-day summer camp. They engaged in a project-based AI literacy program with hands-on activities, data collection and modeling,…

The future of individual and societal progress is largely dependent on students' success following completion of K-12 education. For most traditionally aged students, this entails a journey into higher education at colleges and universities. This transition is rife with pitfalls that may lead students to stop out, fail out, or make inadequate…
