In this study, I documented, analyzed, and compared the thought processes of six high school science teachers during twenty minutes of planning for NGSS-aligned instruction. Teachers' thoughts were captured using a virtual revisit think-aloud protocol and their thoughts were analyzed and compared using a novel tool called a thinking web. A…

Structural reasoning is a combined ability to "look for structures, recognize structures, probe into structures, act upon structures, reason in terms of general structures, and see how a piece of knowledge acquired resolves a perturbation experienced" (Harel and Soto, 2017). The purpose of this study was to explore the cognitive…

Although there is consensus on the relevance of the feedback given to student teachers, few instances in the literature have addressed this topic. Even less is said about feedback to mathematics lesson plans and how to characterize it. Lesson plans are artifacts that help establish a link between theory and practice, relate to a broader sense of…

In this study, I worked with five secondary mathematics preservice teachers (PSTs) in their final year of their undergraduate teacher education program at a large, midwestern university. I examined written lesson plans, observed enacted lessons, and interviewed PSTs about planning and teaching. The purpose of this study was to better understand…

This study investigated secondary mathematics pre-service teachers' (PSTs) knowledge of resources in terms of digital technologies, and explored the processes of both selection and integration of technology into their lesson plans. This study employed a case study design. Participants were six secondary mathematics PSTs who enrolled in a methods…

The teaching and learning of mathematics has been the subject of debate for over 30 years and the most recent reform efforts are in response to concerns regarding the mathematical competence of students in the United States (Ball, Hill, & Bass, 2005; Battista, 1994; Cavanagh, 2008). Standards-based Instructional Materials (SBIM) allows…

This dissertation research examines a teacher educator's instructional practices and preservice teachers' learning in two elementary social studies methods courses. As self-study, it focuses on learning to teach preservice teachers how to select and use visual images to teacher history and social studies. The research uses the Grossman Framework…

Cognitive load theorists claim that problem-centered instruction is not an effective instruction because it is not compatible with human cognitive structure. They argue that the nature of problem-centered instruction tends to over-load learner working memory capacity. That is why many problem-centered practices fail. To better support students and…

This mixed-methods study examined the interactions and learning outcomes of science teachers in an online graduate-level course on evolutionary biology intended to improve their content knowledge and science lesson planning. Discussion posts made by the teachers in this seven-week course were analyzed for cognitive presence using the Community of…
