This qualitative study examined how prospective mathematics teachers attend to, interpret, and respond to student misconceptions through providing them a video-case-based professional development environment. A sample of 30 prospective teachers attending an elective course was asked to watch video cases about student misconceptions related to the…

This research article contributes to the growing literature highlighting the potential for innovation in mathematics education through design cycles that involve creative risk-taking and failure-based learning. Specifically, we explore how "failed" cycles of Story"Circles"--a practice-based professional development approach…

This paper focuses on a professional development program for lower-secondary school mathematics teachers, led by mathematics education researchers, based on historical insights from Fibonacci's Liber Abbaci. The program, involving 25 teachers, emphasized using the history of mathematics to craft meaningful mathematical lessons on the topic of…

Background: Numerous studies show that active and engaging classrooms help students learn and persist in college, but adoption of new teaching practices has been slow. Professional development programs encourage instructors to implement new teaching methods and change the status quo in STEM undergraduate teaching, and structured observations of…

Conceptualized in France during the sixties, the Theory of Didactical Situations [TDS] is a pivotal framework for developing mathematics teaching and learning processes. Despite the increasing qualitative studies over the last ten years, there remains a dearth of analysis of its effects on mathematics education. Through a Grounded Formal Theory…

Studies have found that some teacher professional development programs that are based on Cognitively Guided Instruction (CGI) can increase student mathematics achievement. The mechanism through which those effects are realized has been theorized, but more empirical study is needed. In service of this need, we designed a novel measure of…

Our aim is to contribute to the body of research on learning trajectories (LTs) in mathematics by making visible a process for articulating a hypothetical learning trajectory implicit in a widely adopted, reform-based, middle-grades mathematics curriculum. In doing so, we highlight considerations, decisions, and challenges we faced as part of this…

Current researchers have not been clear on whether or not professional development expenditures, at the school district level, share any possible relationships with student achievement outcomes on state-level summative testing. While there are many articles and numerous research studies on the concept, they are very contradictory in their…

Research has accumulated on the effects of teachers on student achievement, especially in mathematics. However, empirical evidence regarding the impact of formal teacher competence indicators presents a mixed picture. This study explores the influence of educational level, subject -- and grade-specific specialization, teaching experience, and…

Paraeducators provide essential academic support for young learners of mathematics. However, they have limited opportunities to engage in professional development (PD) that is responsive to their instructional needs and role. To scaffold paraeducators' growth, project staff designed, tested, and refined a PD model specifically for K-3…

Textbooks play a vital role in the Nepali education system since they are one of the main resources for teaching and learning mathematics. Because of poor physical infrastructure and inadequate educational resources, both teachers and students heavily rely on textbooks. In this regard, this study investigated the mathematics textbook authors'…

This study focused on the effects of an early math online professional learning course offered to preschool teachers. The course was designed to inform participants' knowledge of developmental progressions and promote daily mathematics instruction that encouraged students to view their world through a mathematical lens. A survey of preschool…

This paper focuses on the discourse of teachers and instructors in a TEAMS (Teaching Exploratively for All Mathematics Students) professional development (PD) setting and on the discursive mechanisms that afford such learning. We conceptualize learning in this PD as a change in a teacher's pedagogical discourse--from alignment with Delivery…

Mounting evidence of the effectiveness of active learning strategies has prompted many mathematics departments to start engaging in transformational change efforts. Change, however, especially change in instructional practice, is a challenging endeavor. Some departments are using coordination of multi-section courses as a vehicle to enact changes…

This study explored how a scenario-based (SB), one-semester professional development program influenced the instructional practices of preservice early childhood mathematics teachers. The participants completed a 15-week program in which they engaged with modeled in-class teaching experience and subsequently answered a number of questions that…
