The term 'DISCUSSION THEME' is a phrase used to describe the main idea or TOPIC of a discussion. It is often used in academic settings, such as in a classroom or lecture hall, to refer to the subject that will be discussed during a particular session. The term can also be used in more informal settings, such as a group of friends discussing a particular issue. In either case, the discussion theme serves as the focus of the conversation and helps to guide the conversation in a particular direction.
