Student Led Topic Discussions
The last 1/3 of the course will consist of student-led topics. Students must research and select a topic proposal, prepare a suggested reading list and in some cases, present a lecture about the topic.
In the first class period of this, each student will propose at least one discussion topic and at the end of the class we will vote on which topics to use in the rest of the course. To propose a topic, the student will give a short talk that defines the topic, says why the topic is interesting, and why the topic deserves your vote. In addition, the student should give a list of papers that might be discussed and suggest 2-3 to be discussed.
Choosing topics and picking the papers takes a lot of work and should be started weeks before the topic-presentation day. We highly advise that you talk to a faculty member about your topic before choosing it. If voted in, a student-led topic would have a short lecture (~1/2 hour) and then paper discussions. Typically the student who proposed the topic gives the lecture and other students are chosen as Answerers for the papers to be discussed.
