The purpose of this paper is to highlight the work of one tripartite partnership with stakeholders to improve and strengthen novice teachers' pedagogical designs using design based professional learning guided by the principles of knowledge building/knowledge creation. The tripartite partnership involved 450 novice teachers from an urban school division, a practitioner-research university team, and the provincial government. Drawing upon one case, this paper analyzes the ways in which the design-based professional learning mirrored the knowledge building/knowledge creation processes highlighting the ways in which teachers worked in collaborative, collective, and connected ways to progressively improve pedagogical designs for collective knowledge building. Computer supported, networked digital technologies provided a community to develop an audit trail to keep track of progressive improvements and refinements to their pedagogical designs and to support, enable, and enhance knowledge building discourse. Design-based professional learning informed by the 12 principles of knowledge building/knowledge creation provided novice teachers with a process to work collectively as a community, progressively improving and refining their pedagogical designs, identifying the role of their pedagogical designs in their students' work, and engaging with other teachers in their respective schools.
