This document summarizes a session on using student work to guide instructional decisions. It discusses the LASW (Looking at Student Work) strategy and Collaborative Assessment Conference protocol, where teachers examine student work samples, speculate on what the student was thinking, and discuss implications for teaching. The session demonstrates this protocol by having teachers examine video and research projects from a high school marketing class, discussing what they notice, wonder, and learn from the student work. Teachers are then asked to consider how this strategy could be useful for examining student work and improving instruction in their own practice.
