What is the Knowledge Quartet?

The Knowledge Quartet (KQ) is a theoretical framework for the analysis and development of mathematics teaching.From the perspective of the KQ, the knowledge and beliefs evidenced in mathematics  teaching can be seen in four dimensions (see image above), named foundation, transformation, connection and contingency. Read an introduction to the KQ here.

What is the purpose of this website?

The purpose of this website is to support researchers wishing to use the Knowledge Quartet for the analysis of mathematics classroom-related data.

Understanding and Using the Knowledge Quartet

In recent years we have been:

– using the KQ as a tool to support focused reflection on the application of teacher knowledge of mathematics subject-matter and didactics in mathematics teaching (Corcoran 2007, Kleve 2009, Rowland & Turner, 2009, Turner, 2009).

– working with early-career teachers, pre-service teachers and their school-based mentors, and with university-based mathematics teacher educators, in applying the KQ to the development of mathematics teaching.

These participants often conceptualise one or more of the dimensions of the KQ in ways that differ from the understandings shared within the research team which conducted the classroom-based research leading to its development and conceptualisation.

“Essentially, the Knowledge Quartet provides a repertoire of ideal types that provide a heuristic to guide attention to, and analysis of, mathematical knowledge-in-use within teaching. However, whereas the basic codes of the taxonomy are clearly grounded in prototypical teaching actions, their grouping to form a more discursive set of superordinate categories – Foundation, Transformation, Connection and Contingency – appears to risk introducing too great an interpretative flexibility unless these categories remain firmly anchored in grounded exemplars of the subordinate codes.”

The purpose of this website is to assist researchers interested in analyzing classroom teaching using the Knowledge Quartet by providing comprehensive coverage to “grounded exemplars” of the 21 contributory codes from primary and secondary classrooms.

Meet the Team

This website is the outcome of a project involving an international team of 12 active researcher-users of the Knowledge Quartet, with the aim of clarifying the intention of each of the constituent codes.

The project is described in

The site is maintained by Tracy Weston & Tim Rowland and is in continuous development. The intention is to add other scenarios of the same kind over time, in the same format, and respond to other inquiries based on the survey found here.
