The challenges of teaching in a large classroom setting. For some introductory courses, the large size format has advantages. Most introductory classes assume little or no prior knowledge of the subject. They can serve as a foundation for students to expand further into the particular discipline. The common background obtained can provide a basis for engaging in subsequent discussions.
Cost efficiency is another advantage of the large class.
While the large classroom setting serves as a cost cutting measure, it can present concerns for students learning. The instructor talks, and the students sit, listen, and copy lecture notes. Also, the instructor may find it difficult to be sure if students are confused or lost, or truly excited about the lecture material presented. The general belief has been that increased class size dictates a lower quality of instruction. With thoughtful preparation, the large class instructor can find success.
