The modules are intended for use directly by individual educators, in professional learning communities, or for preparing to lead the professional development in a school or district setting. The time required for each module can be customized, suitable for a variety of applications, by expanding the amount of time spent on the activities and in discussion.
Each module contains a facilitator's guide, PowerPoint presentations with thorough notes, hands-on activities, related readings and research, recommended topics for discussion, and web and video resources. Refer to the Facilitator's Guide for specific instructions on how to use each part of the module."
