Don't worry about not knowing all your sources in the beginning. The Learning Plan is meant to evolve. At least put down the kinds of resources, even if you don't know exactly which ones. Check out section F, on RESEARCH TOOLS.List the resources you anticipate using to support your learning objectives. They may be people, books, newpapers and magazines, movies, plays, laboratories, organizations and much more. Develop also a bibliography which can be expanded as the semester proceeds.
