In today's seminar class, this semester's theme being public speaking, we began a new section on comparison speeches. The goal is for everyone to make a speech comparing two things that are important to him or her.
Since today's class was a preparation class, we did impromptu speeches on topics that began with the question, "Would you rather..." I translated a list of these gambits that are listed here into English and used them with some modifications to make them applicable to my students. For example, "Would you rather have a one-year supply of chocolate or a lifetime supply of potatoes," I changed potatoes to rice.
The students enjoyed it, and are now ready to prepare topics for comparison.
