This article describes the Literacy Design Collaborative, a network of teachers committed to developing literacy-rich instruction in the content areas and building expertise from teacher to teacher. Drawing on research of adult learning and leveraging new technologies, Literacy Design Collaborative provides the design system, tools, and supports to power effective teacher collaboration and conversations on teacher practice and student learning. Within the Literacy Design Collaborative instructional design system, the task is the anchor for teacher work and student work. Co-designed with teachers, the system guides teachers in a backward design approach that helps teachers create tasks and, from there, strong instructional plans to teach the tasks. While the tools can be used by one teacher who is planning alone, teachers are finding that the tools support collaboration in ways that make the tasks and instructional plans stronger and teacher collaboration real and relevant.
