EnCoMPASS - Emerging Communities for Mathematical Practices and Assessment

NSF Awards: 1222355

2015 (see original presentation & discussion)

Grades K-6, Grades 6-8, Grades 9-12

Through an innovative professional development model, the EnCoMPASS project aims to cultivate a community of teachers by providing online resources and virtual spaces to foster teacher discussion around teacher noticing, formative assessment and productive feedback. In particular, this project seeks to develop an enhanced online environment designed to support teachers’ to closely examine their own and other teachers’ student work on open-middle problems as a means of supporting the community to embody norms and practices that are inherent to productive disposition and high leverage practices for mathematics education. In this video presentation, we discuss both the process and product of the community-supported development of the software with a particular focus on how the software focuses on the teacher practice of Professional Noticing: attending to students work, interpreting student understandings and deciding how to respond (Jacobs, Lamb, & Philipp, 2010). In addition, we discuss how the online nature of community cultivation leads to affordances and constraints with regards to software development and teacher learning.
