With online learning becoming a more viable option for teachers to develop their expertise, our report shares one such effort focused on improving the teaching of statistics. We share design principles and learning opportunities in an online course developed specifically to serve as a widescale online professional development opportunity for…

This study used design experiments, specifically micro-cycle teaching experiments (MTE) as a catalyst for practice-based professional development. The MTE incorporated research-based characteristics of effective professional development: it was embedded in the teachers' daily work of planning and enacting lessons, co-constructed with the…

This paper examines the experience of an action research "Study Day" to investigate development of a culture of reflective practice among educators. Shared recognition of the importance of reflective practice in education is now a well-established part of both pre-service preparation and in-service work experience for educators. Osterman…

Three early career primary school teachers shared their perceptions of changes in their teaching of mathematics 8-18 months after their participation in an action research project. Comparing data collected throughout the lifetime of the project with analyses of participants' reflections written in response to three open-ended questions posed…

The authors worked with 22 middle school math and science teachers for one year with the goal of improving the quantity and quality of inquiry-based instruction implemented in the classroom. The professional development experience was framed by the 4E x 2 Instruction Model, which combines key components of inquiry instruction (Engage, Explore,…

Developing sustainable professional development which facilitates teachers of mathematics to develop effective mathematics pedagogy has been a key aim in recent years. This paper examines how lesson study can be used with networks of teachers as a vehicle to promote and sustain professional development. Drawing on findings from a year-long study…

This article refers to a longitudinal case study of a primary school teacher over a period of 4 years. The focus is on the development of the teacher's beliefs regarding mathematics teaching and learning from the last year of her university studies up to the third year of teaching mathematics in school. This development has been investigated…

This study examined the impact on 16 middle-school teachers' conceptions of mathematics learning and teaching of reflections on their learning experiences within mathematics professional development. The research questions were: In their reflections, what do teachers express about how they best learned mathematics through these learning…

In the context of a three-year professional development program in mathematics, practicing elementary teachers persistently engaged in collaborative inquiry and reflection to build connected meanings for slope. One teacher invented a compelling representation for slope as a process of repeated addition, using Cuisenaire rods, based on teachers'…

Presents a summary of insights gained by the authors after a semester of collaborative teaching. Emphasizes pedagogical and administrative insights. (Author/ASK)

This article describes a specific approach to a teacher investigation of students' written work. The aim of the investigation was for in-service middle school teachers to externalize their thinking about their students' mathematical thinking and to then reflect upon these externalizations and make refinements accordingly. This aim mirrors the…

Historically, teachers implemented mathematics reform recommendations by infusing new activities into the curriculum. However, mathematics instruction continues to be teacher centred, challenging professional developers to find new ways to encourage teachers' growth. This study used activity-reflective cycles (Tzur & Simon, 1999) to examine…

The research objectives were to identify the middle level mathematics teachers' conceptions of mathematics teaching and learning and ascertain changes in their conceptions and instructional behavior at the end of a three-year professional development (PD) project. These changes were studied through the qualitative analysis of their reflective…

Although much is known about the features that contribute to the effectiveness of professional learning activities these are often not incorporated into the design of professional learning initiatives. This paper describes a mathematics professional learning process that was carefully designed to incorporate such principles, and illustrates its…

Describes the Quantitative Understanding: Amplifying Student Achievement and Reasoning (QUASAR) national reform project aimed at studying and fostering the development and implementation of enhanced mathematics instructional programs. It is a framework for reflection based on mathematical tasks used during classroom instruction and the ways in…
