Currently, the perceived use of critical theoretical frameworks to shape instruction in public K-12 education is undergoing intense scrutiny in popular and political debate. Chief among such frameworks has been Critical Race Theory (CRT), which, at the time of this writing, has been legally banned or restricted in eighteen states -- with similar…

In this dissertation study, I recognized the crucial role of mathematics educators' utilization of instructional materials for effective teaching. I highlighted the significance of content that is taught to students through relevant mathematical tasks and representations. Through a detailed examination, I analyzed the similarities and differences…

I provide considerations for TPC instructors and programs regarding developing students' IC skills.I start by examining key conversations and found that issues teaching IC arise when frameworks, texts, and/or individuals do not define key terms related to culture and IC. To address this issue and create a strong foundation, I establish some of the…

The Fountas and Pinnell "Leveled Literacy Intervention System" (LLI), first edition, is a textbook series designed for struggling elementary school readers. The materials have become entrenched in the nation's schools and are currently utilized as an intervention resource in all fifty states and four of the seven largest school districts…

Due to the typological differences between Korean's aspect system and English's aspect system in terms of progressive construction "-ko iss," learners can no doubt have difficulty acquiring and using the "-ko iss" construction in learner Korean. This dissertation investigates two main points: (i) how is the "-ko iss"…

This dissertation research focuses on Open Educational Resources (OER) and OER-based courses as a solution to the rising cost of textbooks. This study focuses on the impact of OER-based courses on student success metrics and examines student and faculty attitudes towards OER-based courses. The study takes place at a medium-sized, rural community…

Open Education Resources (OER) are educational materials that are free and posted on-line for use by teachers and students. The materials can be used as they are posted or mixed and matched with other materials from other on line sources, with the impetus behind the OER movement being the increasing price of textbooks. The purpose of this study…

Despite increasing expectations for student proficiency in content area reading (e.g., Common Core State Standards), social studies text continues to present unique challenges to students who struggle with reading; for example, textbook readability is often at least two grade levels above the grade for which it is intended (Berkeley et al., 2016;…

This dissertation examines students' use of written course materials in introductory engineering courses, begins to elucidate the relationships between students' study habits and their subsequent course performance, and evaluates the impact that carefully designed preparatory assignments has on these relationships. Much of previous educational…

This dissertation will compare how the politics of the early American republic (1790-1800) are portrayed in educational resources and scholarly works. The purpose of this project is to demonstrate that educational materials are both incomplete and positively biased, and therefore teachers of secondary social studies should limit their use when…

Despite their importance, teacher's manuals (TM) have never drawn much attention in language teaching research, and therefore they have not been researched from the perspective of pronunciation teaching. It may be that they have not been perceived as having a role more than being an answer key for student materials (Sheldon, 1987). However, TMs…

An array of north-striking, left-stepping, active normal faults is situated along the southwestern margin of the Gulf of California. This normal fault system is the marginal fault system of the oblique-divergent plate boundary within the Gulf of California. To better understand the role of upper-crustal processes during development of an obliquely…

Concepts of Mathematics (21-127 at CMU) is a course designed to introduce students to the world of abstract mathematics, guiding them from more calculation-based math (that one learns in high school) to higher mathematics, which focuses more on abstract thinking, problem solving, and writing "proofs." This transition tends to be a shock:…

The purpose of this study was to assess the effect of a 3-stage community college mathematics teacher and curriculum conceptual change program on student achievement. The study, which was a replication and extension of Lake (2008), was conducted during Fall 2009 and Spring 2010 terms and focused on teachers' instructional practices relative to…

The textbook holds the potential to serve as an instructional resource, to provide directives on how to effectively teach reading comprehension strategies. In this capacity, the textbook becomes a tool in the teacher's toolkit. With this tool in hand, teachers may be better prepared to face their mission--to improve adolescents' literacy. This…
