In this dissertation, I K-8 mathematics teacher agency and learning within a research-practice partnership (RPP) context. I asked three primary research questions: (a) How is teacher agency enacted within the RPP?; (b) what do teachers perceive they are learning from their participation in the RPP?; and (c) how is teacher agency connected to…

Implementing research-based practices in classrooms as a means of increasing achievement in mathematics for all students requires an understanding of many complex factors that influence classroom change. Situating the role of the teacher as critical to these efforts, teacher inquiry provides a theoretical framework from which to understand the…

It is widely accepted that students' thinking drives teachers' teaching. There are many ways to probe students' thinking with speech or with gestures; however, the literature remains relatively distinct, not focused on both. Prior studies focus on probing students' thinking with speech (talk moves). Although Alibali and colleagues (e.g., Alibali…

This study is an evidence-based mathematical intervention in word problem solving for elementary students. One of the purposes of teaching mathematics is to help students apply mathematics to real life situations. As we know, teaching word problem solving is a very suitable format for this purpose. Schema-based instruction (SBI) is one of the most…

Student problem posing has been advocated for mathematics instruction, and it has been suggested that problem posing can be used to develop students' mathematical content knowledge. But, problem posing has rarely been utilized in university-level mathematics courses. The goal of this teacher-as-researcher study was to develop and investigate…

The purpose of this research was to investigate student conceptions of the topic of asymptotes of rational functions and to understand the connections that students developed between the closely related notions of asymptotes, continuity, and limits. The participants of the study were university students taking Calculus 2 and were mostly freshmen. …

To succeed in an increasing technological and global society, students need to develop strong mathematical and problem-solving skills. This qualitative grounded theory study examined student perceptions of the ways in which teaching strategies in high school mathematics classes affect student motivation to learn the subject. Study participants…

Despite some gains, improving secondary mathematics instruction remains an area of concern of the National Council of Teachers of Mathematics (NCTM). Recitation, also known as lecturing, prevails as the practice of choice of mathematics teachers in the United States. However, the report of the NCTM Research Advisory Committee 2000 indicates that…

There are several factors that have prompted the call for reform in mathematics education (National Council of Teachers of Mathematics [NCTM], 2007). National and international assessments have produced evidence that, on average, students in the United States lack mathematical knowledge and skills (U.S. Department of Education, 2008, n.d.). In…

The goal in differentiating instruction in mixed-ability classrooms is to maximize each student's learning potential. The mixed ability classroom serves learners with a wide range of academic abilities, learning styles, background knowledge, home support, and English language skills. This grounded theory research study examines the dynamics of the…

Under current learning trajectories for length and area, researchers examine how students coordinate and systematize measurement using a given external iterating unit. This study investigates the possible cognitive behaviors missing in that approach by giving students the larger task of comparing areas to see how they construct internal units…
