In academia the most important skill is to ask academically relevant and sound questions. This is not easy and students need to practice asking questions orally and in writing before they write research papers.
Students prepare class discussions by presenting a question inspired by the required readings for the week. They have maximum 5 minutes to introduce the question.
When I introduce the assignment at the beginning of the semester, I tell them they have maximum 5 minutes, because the point is not for them to summarize the readings for students who have not read. They should assume all have read. Their objective is to write a question on a slide or on the board for all to discuss. The question should be open – ideally a 'how' or 'why' question – which will inspire as many students as possible to participate in the discussion. They can use up to 5 minutes to give some background to illustrate why the question is important.
The point is that they should hone their skills at asking academically relevant and inspiring questions for use in their research papers, and this way they gain memorable experience in how the formulations of questions can open up or close down academic inquiry.
