Dear Stephen,
       I have used the internet for an introduction to Mark Twain and his
times.  I began by doing a search for Twain resources myself.  Then I
collected several bookmarks and placed these on the bank of computers at
school.  I created a worksheet which I entitled "Mark Twain Search" and
each student was required to search through the pre-set bookmarks for the
answers.  I had practical questions like birthplace and titles of major
works, but I also listed bonus questions like "Did Twain serve in the
Civil War?" This assignment was done on the 11th grade level in a public
school.  It served to inform the students about Twain, but they also used
problem solving skills and became informed about the internet.
