There is a correlation between language proficiency and achievement in mathematics (Riordain & O'Donoghue, 2009), and this is particularly evident for children who speak English as an additional language or dialect. More effort needs to be made in mathematics classrooms to develop cognitive competencies, including the ability to decode and…

Middle school mathematics teachers face unprecedented challenges. Foremost among those challenges is being able to systematically adapt instructional practices to advance student achievement relative to rigorous math standards. These challenges are not likely to be overcome by individual teachers. That said, it is widely argued that collaborative…

A process was developed to create Web-based video models of effective instructional practices for use in teacher education settings. Three video models, created at three university sites, demonstrated exemplary implementation of specific, evidence-based strategies in reading, math, and science. Video models of strategies were field tested with…

In what unique ways can mathematics tasks contribute to pre-service teachers' understanding of subject matter and pedagogy? And what school mathematics tasks can usefully be included in a pre-service program? To contribute to answering these questions, we report on the selection and choice criteria for mathematics tasks that we use in an…

The design and implementation of the professional development model of the New Zealand Numeracy Development Project has been successful in improving teacher knowledge and practice as well as raising student outcomes. Since 2000, more than 25,000 teachers in English-medium settings have participated in the project. In New Zealand the terms…

The Anthropological Theory of Didactics describes mathematical activity in terms of "mathematical organisations" or "praxeologies" and considers the teacher as the "director of the didactic process" the students carry out, a process that is structured along six dimensions or "didactic moments." This paper…

A nationwide random sample of 179 secondary general education math and special education teachers completed a survey asking them about their use of specific instructional practices to help teach math to students with learning disabilities (LD) and emotional/behavioral disorders (EB/D) and their use of specific assessment accommodations with these…

In this paper I will explore three contrasting teaching and learning environments, including one in which students engage in a "dance of agency". I will move from a consideration of classroom practices to a contention that our work as researchers of mathematics education should pay more attention to teaching practices. Further, that understanding…
