When more than one person is teaching a section of a survey class, it's a good idea to touch base ahead of time. I got in touch with my partner-in-crime this summer and we agreed on a textbook and careful use of occasional primary documents. I planned out the class and various assignments based upon this conversation.
Throught sheer potluck, I just learned that my PIC is also using another textbook, one I've never seen before and about which I know nothing. I have very little time in which to retool my syllabus, not to mention at least scan the book.
Still in all, this is far more fun than struggling with yet another diss rewrite!!
