Three Topics in Descriptive Set Theory

Description: This dissertation deals with three topics in descriptive set theory. First, the order topology is a natural topology on ordinals. In Chapter 2, a complete classification of order topologies on ordinals up to Borel isomorphism is given, answering a question of Benedikt Löwe. Second, a map between separable metrizable spaces X and Y preserves complete metrizability if Y is completely metrizable whenever X is; the map is resolvable if the image of every open (closed) set in X is resolvable in Y.

Well-Being and Academic Success in Gifted College Students: Early-College Entrants and Honors College Students

Description: As a society, we seek to have our young people, including the gifted, be healthy and happy, and go to good schools with good teachers. Framed by Sayler's theoretical model of giftedness and thriving, this study examined psychological constructs (i.e. general self-efficacy, theories of intelligence, hope, gratitude, religiosity, disposition, and resiliency) to determine their mediating effect on personal well-being and academic success in gifted college students. The 213 subjects for this study … more

An Investigation of Preservice Teachers' Understanding of Buoyancy

Description: The purpose of this study was to examine the conceptual understandings of 55 elementary preservice teachers for the concept of buoyancy. This study used Ausubel’s Assimilation Theory (Ausubel, 1963) as a framework for a 15-week intervention that used pre/post concept maps (Cmaps), pre/post face-to-face semi-structured interviews, and drawings as evidences for change of formation of cognitive structures. Using a convergent parallel design and mixed methods approach, preservice teachers’ concepti… more

Comparing Three Approaches for Handling a Fourth Level of Nesting Structure in Cluster-Randomized Trials

Description: This study compared 3 approaches for handling a fourth level of nesting structure when analyzing data from a cluster-randomized trial (CRT). CRTs can include 3 levels of nesting: repeated measures, individual, and cluster levels. However, above the cluster level, there may sometimes be an additional potentially important fourth level of nesting (e.g., schools, districts, etc., depending on the design) that is typically ignored in CRT data analysis. The current study examined the impact of ignor… more

Operationalizing Listening-to-Question and Questioning-to-Listen in Mathematics Teaching

Description: This study focused on the evaluative listening practices of four teachers who participated in an algebra professional development involving lesson study. This instrumental case study operationalizes the enactment of teacher listening followed by teacher questions and responses to define listening-to-question. Also, questioning-to-listen is operationalized as the enactment of purposefully posing questions to posture oneself to listen to students' mathematical thinking. Because of the tacit aspec… more

The Development of Algebraic Reasoning in Undergraduate Elementary Preservice Teachers

Description: Although studies of teacher preparation programs have documented positive changes in mathematical knowledge for teaching with preservice teachers in mathematics content courses, this study focused on the impact of a mathematics methods course and follow-up student teaching assignment. The presumption was that preservice teachers would show growth in their mathematical knowledge during methods since the course was structured around active participation in mathematics, research-based pedagogy, a… more

Mathematics Teacher Motivation in the Context of Lesson Study with Open Approach

Description: Providing professional development to in-service teachers remains a high priority when attempting to meet state and federal school accountability requirements, yet principals may neglect teacher motivation and the teacher change process when facilitating teacher learning. Drawing on self-determination theory, this research examined social and environmental factors shaping teacher motivation in the context of lesson study with open approach. This descriptive case study included the perceptions o… more

Impact of Standards-Based Grading for Algebra I Students

Description: In seeking to maximize student learning, educators must implement grading practices that assess well-defined course standards and clearly articulate student proficiency. Standards-based grading (SBG) practices enhance student learning by linking well-defined course standards and effective feedback. Analysis of variance (ANOVA) testing sought to determine if the use of standards-based grading in Algebra I resulted in higher achievement on standardized tests, specifically the Algebra I the State… more

My Jabez Journey: The Examination of Patriarchy, Power, and Privilege from the Lived Experiences of a Black Female Expatriate Christian Mathematics Teacher

Description: Living and working abroad is one of the best ways to grow and learn about who you are and who you can become. The purpose of the project is to develop and articulate a radical reflexive praxis within the paradigm of the lived experiences of a Black female expatriate Christian mathematics educator. Grounded in the epistemological tradition of Black feminist thought, this study defines the intersectionality of my identity as a Black woman mathematics educator and explores ways it informs my inte… more
