On July 15-17, 2012 the United States National Commission on Mathematics Instruction and Seoul National University held a joint Korea-U.S. workshop on Mathematics Teaching and Curriculum. The workshop was organized to address questions and issues related to math teaching and curriculum that were generated by each country, including the following:…

Educational scholars often describe a research/practice divide. Similarly, students in teacher education programs often struggle to navigate the differences between university coursework and expectations they face in field-based placements. This self-study analyzes one researcher's attempt to address the research/practice divide from the position…

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…

There is compelling evidence that teachers' effective use of formative assessment practices improves student learning, yet many teachers have little knowledge of these practices. In this research note, we highlight our exploratory studies about discourse-based formative assessment practices, an aspect of formative assessment whereby the teacher…

Japanese lesson study, in various adapted forms, is becoming increasingly significant in professional development of mathematics teachers in the USA. Our goal in the research reported in this paper was to investigate, in a three-tiered teaching experiment, the cycles of learning of two researchers, six teachers, and the students in three grade 4…
