An emerging body of research suggests that content-rich literacy instruction has the power to expand elementary children's domain-general and domain-specific literacy skills. For content teachers, such as science teachers, explicit instruction in disciplinary-language and literacy practices can support students reading and writing of school-based…

Despite growing theoretical and empirical evidence that writing has the potential to be an effective tool for student learning in undergraduate mathematics, writing-to-learn integration in mathematics is rare. Major deterrents include perceived lack of alignment between writing and learning goals, deficit views of students' writing abilities, and…

Mathematical justifications offer an approach to which students deepen and extend their mathematical thinking. This process has the potential to enhance students' conceptual understanding. Mathematical practices and process standards ask students to use critical thinking skills to justify their reasoning, but this is usually seen as proofs in high…

This research study examined the relationship between school leadership style and the use of writing across the curriculum (WAC) in secondary classrooms. Writing practices and the use of writing as a form of assessment in subject areas other than ELA is thought to be a way to better prepare students to meet the literacy expectations of the 21st…

The impostor phenomenon is "a psychological experience of intellectual fraudulence where one struggles to internalize successes, instead attributing personal accomplishments to chance, luck, or trickery" (Clance, 1985). Through this dissertation study, Guthrie and four co-researchers, Mindy, Bobbie, Rosalie, and Lisa, explored the…

Efforts to improve technology integration for K-12 teaching and learning focus on professional development for teachers. This research study, however, implemented a professional development course in technology integration for educational content writers at a publisher in the Southeastern United States. This research is strategic because most…

Literacy development is an essential aspect of academic success. Educational institutions have worked to implement various strategies and initiatives to increase students' literacy skills. Understanding the insights of both students and teachers is important for utilizing these skills effectively and if they have impact. Implementing strategies…

The ability to write well is inextricably linked to reading comprehension, acquisition of content knowledge, and college and career readiness. Many adolescent students, especially those from economically challenged (EC) households, struggle in their ability to communicate in writing, especially in writing to explain or inform across subject areas.…

Research on disciplinary variation in graduate student writing (GSW) has typically focused on theses and dissertations. Less attention has been paid to coursework assignments (e.g., essays, recounts, exercises, etc.), which are the pre-cursors to final capstone projects. Coursework papers are prioritized by both students and professors because…

This dissertation study explores the emergence of off-task engagement, in which three Chinese first-graders write mathematically. It seeks the solution to the conflict between the intended mathematics writing and the realized mathematics writing, which ties to the Cartesian rationality dominating mathematics classrooms--that tends to ignore…

That writing can support students' learning in science and mathematics has been documented, yet little is known about how empirical findings have been applied in (1) materials designed to support science and math instruction; and (2) informal learning environments mediated by peer instructors. This dissertation examines two relatively unexplored…

The purpose of this study, secondary data analysis, was to analyze the argumentative and informative essay writing of middle school students with disabilities. Inflectional, derivational, and compound word morphological forms within 360 essays were coded and analyzed using descriptive and inferential statistics. Results are grouped into categories…

Research supports the finding that middle school students prefer hands-on activities to reading and writing to learn new information. However, disciplinary literacy, the reading and writing in science class, is an integral part of inquiry-based science instruction and a necessary complement to hands-on instruction to build student understanding.…

Written assignments are, perhaps, one of the most common types of coursework that students will encounter in their undergraduate studies. This study describes the communicative purpose and textual and linguistic characteristics of university assignments written for content classes, taking into account variation across communicative text types and…

The dissertation is composed of two main parts. The first half describes efforts to study amyloid peptides using macrocyclic peptide model systems, and the potential deleterious effects of uronium peptide coupling agents on human health. The second half focuses on my experience in chemistry teaching and the chemical education research I conducted.…
