Through a series of four papers, this dissertation investigates developmental mathematics students' experiences with relearning, or the experience of learning about content one has already tried to learn in a previous mathematics course. Developmental math courses typically focus on K-12 algebra, and are required for graduation but notorious for…

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…

Adult first language (L1) English speakers who are advanced second language (L2) learners of Spanish demonstrate near-ceiling levels of accuracy for some features of Spanish, such as [Person] and [Number] for verbs (McCarthy, 2012; Rodgers, 2011). While for other features, such as [Aspect] for copulas (i.e. ser and estar), and [Person] and…

How do teachers and students create classroom environments in which mathematical errors are regarded as important opportunities for learning? What norms support students in learning from their errors, and how to these norms develop in a classroom community? This dissertation addresses these questions through a longitudinal case study investigating…

This dissertation investigates the longitudinal development of Chinese language proficiency among students in a Chinese as a Foreign Language (CFL) Flagship Program at an American public university from 2014 to 2024. Using Bayesian multilevel regression models, this study assesses the trajectories of listening, speaking, and reading proficiency…

A longstanding aim of education efforts to position students as knowledge constructors so they are engaged in the building and shaping their learning environment. Current education reforms situate student sense making around authentic science inquiries where students are engaged in the practices of science. In the science classroom, this means…

This dissertation investigates the effect of observational learning in crowdsourcing markets as a lens to identify appropriate mechanism(s) for sustaining this increasingly popular business model. Observational learning occurs when crowdsourcing participating agents obtain knowledge from signals they observe in the marketplace and incorporate such…

This dissertation reports on a qualitative longitudinal study that explores the original conceptualization of drama-based instruction (DBI) in the L2 classroom among ten K-12 teacher-candidates in a language teacher preparation program. It gives particular attention to two case study participants as they continued to (re)conceptualize drama-based…

This study examines the effect of deep approaches to learning on development of the inclination to inquire and lifelong learning over four years, as an essential graduated outcome that helps students face the challenges of a complex and rapidly changing world. Despite the importance of the inclination to inquire and lifelong learning, some…

Digital media is a broad concept that includes everything from movies to video games to websites. These media are cultural norms for young people, becoming part of their identity as they use and create content.
