This document describes the development of a self-instructional module on using Web 2.0 tools for teachers. It outlines the module goals, which are to define blogs and wikis and select the appropriate tool to meet instructional goals. It describes gathering feedback from teachers during one-on-one sessions to test and improve the module. Revisions were made based on the feedback to better explain examples and tools. Lessons were learned around planning, understanding the audience, and testing ideas early in the process.
