The ties between literacy and numeracy exist in the development of vocabulary and language for understanding mathematical concepts. Research indicates that explicit instruction in mathematics vocabulary supports success with mathematics problem solving (Biemiller 2009; Pierce and Fontaine 2009; Rubenstein and Thompson 2002) for native…

This article analyses lesson study as a mode of professional learning, focused on the development of mathematical problem solving processes, using the lens of cultural-historical activity theory. In particular, we draw attention to two activity systems, the classroom system and the lesson-study system, and the importance of making artefacts…

A teacher can be the most important resource in a school. When the teacher's attitude derives from asset-based thinking, positive impact can occur for both teacher and student. Asset-based thinking is defined as "a way of viewing reality." Those who embrace this model approach things from a positive as opposed to a negative perspective.…

Using narrative inquiry as a research method, four mathematics and mathematics education faculty members explored the integration of theoretical perspectives into their personal narratives as they developed a community of practice. Initially their focus was strictly on improving their students' mathematical knowledge. As their community of…

Partnership with teachers for professional development has been considered beneficial because of the potential of collaborative work in the teacher's own classroom to be relevant to practice. From this perspective, both teachers and researchers can draw on their own expertise and work as authentic partners. In this study, we address the need for…

This article presents an Exponential Growth Learning Trajectory (EGLT), a trajectory identifying and characterizing middle grade students' initial and developing understanding of exponential growth as a result of an instructional emphasis on covariation. The EGLT explicates students' thinking and learning over time in relation to a set of tasks…

I investigate the sustainability of lesson study as mathematics teachers who participated in a 3-year professional development partnership engage in a district scale-up lesson study professional experience. This study answers three questions: (1) what are K-12 teachers' conceptions of sustaining mathematics lesson study, (2) what practices of…

This paper explores how a secondary school in western Sydney used educational research as an impetus to change its mathematical education culture over a three year period. Key changes occurred in four areas: leadership; pedagogy; structures for teaching and learning; and mathematical environments. These included increased professional…

In this article we describe a secondary-postsecondary collaborative partnership that addressed the issue of students' frequent failures as they transition from high school to college mathematics courses. Although the partnership did not take place in a professional development school, secondary and postsecondary participants worked together as…

Teacher collaboration has been recognized as a vital component to student success. This project represents an evaluation of the researchers' initial efforts toward providing in-service education for teachers focused on collaboration between math and CTE teachers. The purpose of this study was to (1) describe selected characteristics of secondary…

The aim of this study is to investigate the strategies employed by advanced high school and university students working on six tasks concerning comparison and conservation of area. Special care has been taken in the test design so that the problems could be dealt with using a variety of solution methods. Written responses and in-depth interviews…

The purpose of this article is to report on a formative evaluation research study of a university-school partnership for mathematics and science education within a community engagement and social justice perspective in higher education in order to inform redesign and replicability. The partnership involved the school-based systemic intervention…

NS-eCMS is developing an open web-based content management, communication, and collaboration eLearning platform that addresses the specialized requirements for distance education in natural sciences. The federated architecture enables straightforward development, exchange, and publication of material through open standards like XML/MathML. The…
