And does it work? I've been griping to colleagues over the last several months about my failures to inspire good class discussions, and some have simply said, "up the participation percent." Folks, does this work for you? If so, what was the magic number?

I am currently evaluating rhetoric textbooks, handbooks, and readers for my class next year, and I realized how the best information tends to come from fellow graduate students, normally in random, informal conversations. It would be useful to collect this practitioner lore in one place where we can all access it. So, please submit your reviews of rhetoric handbooks here!
