Lesson Activity #5 WELES: TRY

Lesson Activity #5:
The learner will select a topic (or one will be assigned) of a broad and general historical nature (e.g. The Civil War, The U.S Presidency, The Fifty States). The learner will construct an outline of topics and subtopics stemming from the main topic, which results from using search engines on the Internet. The learner will document each level and sub-level of the outline with a supporting website and list the search engine used to find the reference. As a culminating activity, the learner will write a brief essay that summarizes the search strategies and search engines he or she found to be most effective.

Lesson Activity #5 Supporting Web Information:
The Library of Congress offers its own classification outline that can be used by the learner as a first reference:

Additional Notes:
The lesson is easily flexible depending on the level of students involved and time period allotted. The lesson is designed to move the learner through each of the four WELES strategies of Frame, Inform, Explore and Try and in doing so, the instructor moves from dispenser of information, to guide and resource person.
