This study draws upon critical bifocality (Chen & Horn, 2022) and intersectional frameworks (Collins, 2019; Crenshaw, 1989) to detail critical consciousness development over time in justice-oriented elementary mathematics educators. Specifically, a Critical Participatory Inquiry (CPI) approach facilitated collective theorizing amongst myself…

This study investigated how three fifth-grade students' understanding of fraction and decimal magnitude evolved over the course of a five-week teaching experiment. Students participated in teaching and learning sessions focused on developing concepts of fraction and decimal magnitude. The following questions guided this study: (1) How do fifth…

This study examined the practices of a mathematics coach by analyzing coaching moves over multiple coaching cycles with two teachers. The coach, guided initially by a content-focused model of coaching (West & Staub, 2013), engaged teachers in cycles that consisted of co-planning, teaching, and debriefing conversations to help teachers reflect…

Teachers' daily instructional practices are a critical component in creating a rich and meaningful educational experience for students. Thus, factors that inform instructional practices are of particular importance and interest to education researchers and other stakeholders. Beliefs about teaching and learning are a known factor influencing…

The purpose of this qualitative descriptive study is to examine how 3rd-8th grade teachers describe their use of educational technology for experiential learning in mathematics in the Southwestern United States. David Kolb et al. (2001) experiential learning theory guided the two research questions on the level of use and how teachers described…

Math proficiency in the elementary grades is one component to ensuring a highly qualified science, math, engineering, and technology workforce. The literature indicates that teachers of those early years greatly impact their students' future attitudes and abilities in the STEM fields. Therefore, it is critical that administrators, teacher…

With traditional teaching methods pervasive in the U.S., it is crucial that mathematics teacher educators and professional development leaders understand what methods result in authentic changes in classroom instruction. Lesson study presents a promising approach to developing reform-oriented instruction, as it is situated within the classroom,…

Preschool teachers are expected to engage young children in challenging and supportive mathematics learning. Rich and responsive language experiences in mathematics support children's language acquisition and engagement related to mathematics, however, such engaging experiences may be minimally available to many young children. Professional…

The use of mathematics performance tasks can provide a window into how a student is applying mathematics to various situations, how they are reasoning mathematically and how they are applying conceptual knowledge through problem solving and critical thinking. The purpose of this study was to investigate, according to the elementary mathematics…

PISA is a large international educational assessment activity coordinated by the "Organization for Economic Co-operation and Development" (OECD). PISA's "Functional Literacy" emphasizes the theoretical concept of mathematics as a human activity. From this pedagogical point of view, PISA's "mathematization cycle"…

The purpose of this study was to better comprehend the experiences of middle school teachers when they are asked to implement practices promoted in professional development. The professional development in which the teachers were involved centered on cultivating classroom discourse through the use of six Teacher Discourse Moves. These moves were…

Teachers face new challenges when they teach a more rigorous mathematics curriculum than one to which they are accustomed. The rationale for this particular study originated from watching teachers struggle with understanding mathematical content and pedagogical practices. Mathematics coaches can address teachers' concerns through sustained,…

Researchers have suggested that teachers use a specialized type of knowledge specifically attributed to the work of teaching. One aspect of this specific type of knowledge is the ability to analyze children's work. With continued emphasis on a teacher's ability to analyze their students' thought processes, teacher candidates will need to develop…

This dissertation builds on research about teacher identities (e.g., Agee, 2004; Sumara & Luce-Kapler, 1996; Ronfeldt & Grossman, 2008), teaching mathematics for social justice (e.g., Felton, 2010; Gutstein, 2006; Skovsmose, 1985; Stinson & Wager, 2012) and learning to teach mathematics for social justice (e.g., Gau, 2005; Gonzalez,…

In the two decades since the introduction of the Professional Standards for Teaching Mathematics (NCTM, 1991) describing effective mathematics instruction, researchers have found U.S. teachers still lack the ability to foster productive mathematical discourse. Three instructional practices are key to teachers' ability to support rich…
