Choose a seat in the seminar room so that the the participants and the seminar leader are clearly visible to you.
Always come prepared to the seminar. Preparation requires reading the texts covered in the seminar. Think about the concepts and ideas in the texts. Compile a list of questions and critical points that emerge from your reading of the text and use the questions and critical points as your point of departure in participating in the seminar discussion.
Don't dominate the seminar discussion. A seminar should permit each participant to contribute to the discussion. The goal is to discuss and debate a topic.
Listen attentively when other participants speak. Focused on their comments and don't let your mind wander. Jot down critical notes about the essential points of their argument and use the notes to raise critical remarks and questions about their argument or point of view.
Speak clearly and concisely when you raise a question or make a critical observation. Think about the point you want to raise and stay on target when you speak. Be polite and respectful when you disagreeing with someone. Respectfully show why you think their argument is wrong, flawed or one-sided. Support your own point of view with a well-reasoned argument.
