In this dissertation, I establish a research program that uses computational modeling as a testbed for theories of phonological learning. This dissertation focuses on a fundamental question: how do children acquire sound patterns from noisy, real-world data, especially in the presence of lexical exceptions that defy regular patterns? For instance,…

College students are asked to make critical decisions about which academic major to choose and subsequently to make specific career decisions. Students come to college with a myriad of different skill sets, backgrounds, developmental levels, cognitive processes, familial support, and levels of self-efficacy that may influence how they make these…

This study aimed to learn the subjective experiences of higher education business students pursuing intercultural development goals. As part of their academic programs students completed the Intercultural Development Inventory (IDI) assessment and received intercultural competency scores. Subsequently, they created personal goals to further…

We are currently in a century of data where massive amount of data are collected and processed every day, and machine learning plays a critical role in automatically processing the data and mining useful information from it for making decisions. Despite the wide and successful applications of machine learning in different fields, the robustness of…

High school science teachers are a unique subset of teachers with distinctive PD needs in content, pedagogy, and technology, yet there is scant research about PD from the perspective of secondary science teachers. This qualitative research study used narrative research methods with grounded theory to explore how a group of seven high school…

Using the Compassionate Music Teaching (CMT) framework as a lens, in this study I explored the ways that teachers of adults learning recreationally in music lessons may align their teaching approaches to learners' adult-specific needs. Adult education scholars have accentuated the need for facilitators of adult learning to consider adult learners'…

This dissertation explored how effectively first-year writing (FYW) evaluated and selected sources for their researched writing assignments. Though students were taught how to access sources from the library and offered sources on the course management system, most often they obtained sources via the open internet. As mis- and disinformation…

In interactive e-learning environments such as Intelligent Tutoring Systems, there are pedagogical decisions to make at two main levels of granularity: whole problems and single steps. Here, we focus on making the problem-level decisions of worked example (WE) vs. problem solving (PS) and the step-level decisions of elicit vs. tell. More…

The goal of the continuous improvement process in North Dakota K-12 education is to review and adjust practice to best support student learning. This study considered the continuous improvement services and supports provided by North Dakota Department of Public Instruction (NDDPI), such as providing training and support through regional education…

Preschool teachers use their ideals as a sifter to comb through their most pertinent funds of knowledge related to mealtimes with young children. The purpose of this two-cycle action research study was to investigate and enhance child-feeding professional learning opportunities--targeted at early childhood educators working with young children…

Students do their best work when they have a sense of agency around science and science learning. Scientific practices like argumentation and critique are areas in which students' agency is especially visible, as they require many points of decision-making and evaluation. While argumentation and critique are fundamental practices in both classroom…

Data-driven learning uncontroversially plays a role in human language acquisition--how large a role is a matter of much debate. The success of artificial neural networks in NLP in recent years calls for a re-evaluation of our understanding of the possibilities for learning grammar from data alone. This dissertation argues the case for using…

Children in under-resourced schools are often subjected to a "pedagogy of poverty," in which their school days consist primarily of independently completing worksheets and preparing for assessments. By contrast, children in more affluent schools often experience engaging, hands-on learning opportunities. This discrepancy is identified as…

Prior research has established preservice literacy teachers' beliefs about teaching and learning are often misguided and/or overly-simplistic, yet limited work has examined in what ways their in-the-moment teaching decisions align or misalign with what they believe. This qualitative study used deductive analysis methods to: (1) Identify three…

With the innovation of the internet, the learner is able to access his or her online classroom anytime, and anywhere based on the customized online learning environment by instructional designers. Creating online learning environments, also known as instructional design, can be challenging. This research focused on how instructional designers…
