Learn to listen critically and sympathetically. Listen for what the presenter means rather than pick at words or specific arguments. Have textual evidence at hand. If warranted, propose alternative assumptions. Suggest more effective arguments, assuming you have reasons and evidence.
Effective conversation benefits everyone.
If you're brilliant and articulate, don't dominate discussion on this conviction alone. To assist students in selecting an interesting and manageable topic, a list of suggested topics has been included with the syllabus. The list is by no means exhaustive and is intended to pose suitably focused titles. Find a topic that interest you. Clarify for yourself what topic holds interest then isolate the issues that make the topic meaningful, controversial, troubling.
