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 investigated the impact of a year-long professional development (PD) program on mathematics teachers' knowledge, beliefs, and practice. The PD program of the study was designed to connect mathematics teachers' learning and teaching practice through integrating situated aspects of the teaching profession and teachers' reflections. Data…

Effective teacher education is expected to ensure that future teachers acquire professional knowledge that is relevant for coping successfully with the requirements of their teaching practice. To strengthen evidence-based teacher education, we need to better understand which teacher education outcomes are predictive for high-quality instruction…

Teacher leadership is essential for increasing teacher quality, addressing teacher turnover, and ultimately improving student learning. In this paper, we describe a teacher leadership program that developed 14 secondary mathematics teacher leaders. The quantitative data from the assessments and surveys indicate improvement of knowledge for…

This study examined changes in beliefs and confidence of 24 pre-service mathematics teachers after they participated in professional learning in an algebra pedagogy course, which addressed an under-researched area about their domain-specific beliefs in teaching algebra. A single-group pretest-posttest design was adopted. Quantitative data were…

Effective teachers have knowledge not only of the subject they are teaching, but also of how to teach it appropriately. To develop these aspects of knowledge, faculties of education include a number of courses that address the related skills. From the perspective of mathematics teacher education, courses related to mathematics teaching have come…

Improving instruction in elementary mathematics is critical to supporting better academic and life outcomes for our students. While weak elementary math instruction is not a new challenge, the COVID-19 pandemic appears to have exacerbated the issue. Many states have reported that students have lost more learning in math than in reading over the…

This program focused on improving mathematics content and pedagogy for Algebra I teachers, including regular classroom teachers and exceptional education teachers, as they implemented the Tennessee Mathematics Standards. Concentrating work on a few topics allowed for tightening breadth while increasing depth of content, as well as devoting study…

As the most important in-school factor in student learning, elementary school teachers must be able to offer all students the quality mathematical learning experiences that they deserve; and the opportunities to learn that pre-service teachers (PSTs) encounter during their preparation programs impact their ability to do so. Content courses are…

This study describes a professional development (PD) program designed to support middle school teachers in effectively integrating robotics in science and mathematics classrooms. The PD program encouraged the teachers to develop their own science and mathematics lessons, aligned with national standards, infused with robotic activities. A…

This study examined the intersections of preservice elementary teachers' (PSET) professional noticing (PN) of children's mathematical thinking, two mathematical knowledge for teaching (MKT) domains: mathematics content knowledge (MCK) and mathematics pedagogical content knowledge (MPCK), and two affective domains: attitudes and dispositions toward…

This qualitative study examined how participating in-service teachers demonstrated linguistically and culturally responsive mathematical teaching (LCRMT) competences after they completed a year-long National Professional Development Program grant-funded project. A two-dimensional LCRMT framework was developed to measure participating teachers'…

Mathematical knowledge for teaching is a complex web of knowledge domains. In this article, we share findings from an 18-month professional development project that aimed to improve middle school mathematics teachers' mathematical knowledge for teaching (MKT) of proportional reasoning by focusing on the critical analysis of mathematical tasks and…

Professional development is necessary to support and empower teachers in meeting the high stakes demands of mathematics teaching and to ensure equitable, accessible, and high-quality instruction for all students. Using the Interconnected Model of Professional Growth, we designed and implemented a longitudinal, multi-faceted professional…

Research indicates that a large percentage of students have misconceptions of the equal sign and that this can be detrimental to their mathematical pursuits as they progress through algebra. In order for students to develop a strong understanding of the meaning of the equal sign, algebra teachers must be aware of the viewpoints their students will…
