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…

The mathematical knowledge for primary teachers has been guided by policy since the National Strategies Programme was introduced in 1999. Research regarding the National Strategies focussed on the outcomes of the policy rather than in terms of teachers' mathematical knowledge for teaching (MKT). Teachers respond to policy in a variety of ways…

"Out-of-field teaching" is an international phenomenon that seems particularly prevalent in mathematics. Our study is evaluating the impact of a national professional learning program for out-of-field secondary mathematics teachers in Ireland. Using the Productive Pedagogies framework, we compared the pedagogical practices of three pairs…

By examining the effects of a national-scale teacher professional development (PD) program on instructional practices and student mathematics achievement, we contribute to calls for empirical studies investigating the impacts of such programs conducted at scale. The program corresponds well with core critical features of high-quality teacher PD…

'Out-of-field teaching' refers to the practice of assigning teachers to teach subjects that do not match their training or education -- an international phenomenon that seems particularly prevalent in mathematics. This paper reports on a study evaluating the impact of a national professional learning program for out-of-field secondary mathematics…

The processes of mathematisation, the use of mathematical models and representations of real world contexts, and contextualisation, the embedding of mathematical ideas into a meaningful context, are key aspects of students' mathematical learning. We present a conceptual framework for thinking about mathematising and contextualising developed as…

Using data from Achieving the Dream: Community Colleges Count, this issue of "Data Notes" investigates the number of attempts it takes students to complete all developmental education courses to which they are referred. Subsequent gateway course completion and overall persistence are also examined. Three-year outcomes were analyzed and…

"Data Notes" is a bimonthly publication that examines data to illuminate the challenges facing Achieving the Dream colleges and to chart their progress over time. Gateway courses generally include the first college-level English and math courses students are required to take. Increasing the number of students who attempt gateway classes…

In the late seventies, Guy Brousseau set himself the goal of verifying experimentally a theory he had been building up for a number of years. The theory, consistent with what was later named (non-radical) constructivism, was that children, in suitable carefully arranged circumstances, can build their own knowledge of mathematics. The experiment,…

For more than 50 years, the International Association for the Evaluation of Educational Achievement (IEA) has been instrumental in developing an analytical model for understanding the relationships between educational policy (the intended curriculum), classroom and instructional practices (the implemented curriculum), and educational learning…

Using data from Achieving the Dream: Community Colleges Count, this issue of "Data Notes" looks at student developmental education and gateway course outcomes by gender. The data show that more than half of students were referred to developmental math, with female students being more likely to be referred than male students. Females were more…

The U.S. Department of Education makes a considerable investment in math and science education each year. This document discusses the Eisenhower Mathematics and Science Education Program, the largest of the Department of Education's programs dedicated to math and science. This program includes: (1) The National Program (funding nearly $16 million…

The author reviews the process of metric conversion in the United States, the organizations involved, and popular reactions. Concluding that, despite setbacks and uncertain public opinion, this country is embarked on a slow but deliberate path toward metrication, he suggests some guidelines for teaching metrics. (SJL)

The results of exercises related to fractions on the National Assessment of Educational Progress (NAEP) for 9- and 13-year-olds are reported. This discussion is followed by suggestions on ways to help students be more successful when adding fractions. (MP)

In response to a call for new content and instructional techniques in the teaching of mathematics, the Public Broadcasting Service (PBS) has launched an organization called MATHLINE, whose first project involved facilitating electronic communication among mathematics teachers nationwide. This document describes a study which examined the members'…
