The National Science Foundation (nsf.gov) has funded a large initiative to catalog collections of high-quality online resources into the National Science Digital Library (nsdl.org). The mission of the NSDL is to help improve education for all teachers and students. The purpose of this module is to help you find high-quality online resources, learn strategies for incorporating them into a free software tool called the Instructional Architect, and use these projects in an instructional situation. In this module, you will learn to access online resources and to use tools to help solve instructional or learning problems or issues that you currently face in your classroom. You will also learn about reviewing IA projects to help you in choosing projects you can reuse and in designing your own.
