This multiple case study dissertation aimed to examine one of the domains of pedagogical content knowledge, knowledge of content and students, between different types of elementary coaches and between coach and their respective collaborating teachers. It also investigated the impact a coaches' background experiences have on the dynamic between…

This sequential explanatory mixed methods study explores elementary mathematics teachers' perceptions regarding their mathematical self-efficacy, how teachers describe their perceptions about their prior mathematical learning experiences and their impact on their instructional practice in the elementary mathematics classroom. In support of this…

A disproportionate number of preservice elementary teachers exhibit high levels of math anxiety (Reid et al., 2018). Not only does this inhibit their ability to understand mathematical concepts, but it also negatively impacts their pedagogical approach to math (Beilock & Maloney, 2015; Reid et al., 2018). Teachers who experience math anxiety…

Although teachers agree that technology is beneficial for enhancing math education and pedagogy, there are concerns about incorporating technology into their teaching practices. The problem addressed in this study was that high school teachers are challenged to integrate technology into math instruction. The purpose of this basic qualitative study…

Literature shows that the Nature of Mathematics Knowledge (NOMK) dates back to the era of Plato and Aristotle (Dossey, 1992). It suggests that mathematics teachers' beliefs, views, conceptions, and preferences about NOM influence the way in which they teach mathematics. It is important to understand how these conceptions are formed, which may…

This study aims to elucidate a common professional learning opportunity in Japan, "instructional circles," which has not yet been studied systematically or described in detail. This study uses the mathematical knowledge for teaching (MKT) framework and research on features of professional learning opportunities that facilitate intended…

Mathematics is often taught by lecturing students on how to perform procedures, but it could be taught in ways that promote active student engagement and develop deep conceptual understanding. Research supports the latter approach as better for students' retention, engagement, and success with learning mathematics. An important time to influence…

With the changes in Common Core State Standards, it was essential to explore how elementary pre-service teachers' sense of fractions is developing and their thoughts about how to teach fractions. A gap in practice exists because it is unknown how pre-service elementary teachers, after student-teaching, perceive their level of in-practice knowledge…

The purpose of this applied research study with a program evaluation was to answer fundamental questions about the effectiveness of an extended professional development program. The program sought to promote quality mathematics instruction by increasing teachers' knowledge of and supporting the implementation of effective mathematics teaching…

This study explored the potential connections between secondary in-service (ISTs) and preservice (PSTs) mathematics teachers' anticipations and their noticing of student thinking in technology-mediated learning environments, a topic with limited prior research. Specifically, the study examined how teachers (ISTs and PSTs) anticipate student…

This multiple case study explores how two elementary mathematics teachers made themselves and their students comfortable with the teacher delegating authority to students while also positioning them with agency. I conducted three Video-Stimulated Recall (VSR) interviews and pre- and post-semi-structured interviews with each teacher to understand…

Educational technology has the potential to be transformative in secondary mathematics classrooms. Recent events have further necessitated a paradigm shift in how technology is used. In this mixed methods action research study, I study the inputs to effective technology use and establish a combined model that shows their interaction with each…

Students with disabilities and/or those who have difficulty learning mathematical concepts can be found in almost every classroom. Over the last several decades, the responsibilities and roles of general and special education educators have shifted, blurring the conventionally held boundaries between special education and general education…

Schools across the country are struggling to retain STEM teachers, particularly secondary math and science teachers. Mentoring has been a successful tool to help build the confidence of novice teachers and to help lower attrition rates. Further, because it takes time and support to develop robust pedagogical content knowledge (PCK), the mentoring…

Over the past thirty years, research on teachers' mathematical knowledge for teaching (MKT) has developed and grown in popularity as an area of focus for improving mathematics teaching and students' learning. Many scholars have investigated types of knowledge teachers use when teaching and the relationship between teacher knowledge and student…
