M: In this department, a class could be as small as 5 students or as large as over 200. The largest classes are lecture classes, usually in introductory courses at the undergraduate level. (1)_________________________.
W: In what forms are classes given?
M: Generally speaking, classes are given in three formats---lectures, seminars and laboratory work. Lecture courses usually include two lecture sessions and one discussion group per week. Lectures are given by professors who will talk on specific topic for one class period. Students have little chance to ask questions. Discussions are conducted by postgraduates and provide the opportunity for questions about the lecture topics.
W: How about seminars?
M: Seminars involve a small group of students and place more responsibility on them. (2)_________________________. Students are free to exchange their ideas. The seminar challenges students’ reasoning and organizing abilities.
W: And laboratory work?

W: They all sound interesting to me. Do you know how we’re assessed?
M: (3)_________________________. Other course examinations are mid-term exams and final exams, which include multiple-choice questions, short answer questions and essay questions. Research papers are another form of examination. Have I made myself clear to you?
W: Yes. I understand now. Thank you. Dr. Wilson.
