Despite the evidence of its effectiveness on student learning, ambitious mathematics instruction has proven to be challenging for teachers to enact. Increasingly, instructional coaching programs have become a way of providing intensive one-on-one support to teachers to improve the quality of mathematics instruction. Researchers have identified…

Background and objectives: An early understanding of numerosity is crucial to developing proficiency in arithmetic, and rapid pattern recognition via subitizing is key in this process. The training app "LORE" specifically targets and cultivates pattern recognition skills from the beginning of formal schooling. This study investigated…

We examine the effects of a year-long national-scale professional development (PD) program on mathematics instructional quality. In contrast to previous studies examining the effects of this program on instruction by comparing before and after participation or participants and non-participants, we examine whether instructional quality changed…

A traditional faculty member's job function involves both teaching and research. However, unlike in K-12 education, the majority of faculty members have little to no formal training on teaching methods prior to entering the classroom. This study focuses on implementing Lesson Study as a form of professional development in higher education to…

Adaptive learning support provided by kindergarten teachers before and after (macro-adaptive learning support) as well as during mathematical learning activities (micro-adaptive learning support) is a cross-cutting concept of teaching quality. Effective adaptive learning support enhances children's learning. However, providing it is challenging…

Modeling with mathematics (MP4) is a mathematical practice standard that can be used to engage students in mathematical content standards as well as additional mathematical practice standards. Research has shown the benefits of mathematical modeling (e.g., Aguirre et al., 2019; Cirillo et al., 2016a), but also the challenges teachers can face…

This study described the experiences of a group of seven sixth-grade teachers and the participation of their emergent bilingual students (EBs) during the implementation of an instructional protocol designed to provide students with opportunities to engage in mathematical reasoning through discourse. The Discursive Mathematics Protocol (DMP) is…

U. S. educational policies focused on the use of high-stakes standardized achievement tests and top-down accountability to improve student achievement have had an insignificant impact. Furthermore, the focus on once-a-year standardized tests to measure student success negatively impacts daily classroom instruction and assessment practices.…

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 action research study examined the effects of professional development on teaching for conceptual understanding in Algebra I. "Conceptual knowledge refers to knowledge of the underlying structure of mathematics-the relationships and interconnections of ideas that explain and give meaning to mathematical procedures" (Eisenhart et…

Prosocial and Active Learning (PAL) Classrooms is a year-long teacher professional development program designed to increase students' prosocial behavior and engagement in 5th grade mathematics and science classrooms that use active, team-based lessons by altering the way that teachers interact with students using research-based strategies. The…

Purpose: The aim of this study is to illuminate the perceptions of the essential factors for sustaining Learning Study of the curriculum leaders who have led Learning Study in schools over a sustained period. Design/methodology/approach: This study adopted a case study research approach to explore the perspectives of the curriculum leaders…

The aim of this study is to determine the level of compliance of the educational digital game designs developed by the form teachers for teaching mathematics with the determined criteria and to analyze the opinions of the classroom teachers on the educational digital game design process. Case study, one of the qualitative research designs, was…

Lesson study is a model of effective professional development that originated in Japan and has become popular among math teachers worldwide in recent decades. Idaho math teachers have engaged in lesson study as a method of professional development for the past six years. Research is needed to determine the impact of lesson study on the…

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…
