. Lectures are used to convey critical information, history, background, theories and equations. A politician's speech, a minister's sermon, or even a businessman's sales presentation may be similar in form to a lecture. Usually the lecturer will stand at the front of the room and recite information relevant to the lecture's content.

Though lectures are much criticised as a teaching method, universities have not yet found practical alternative teaching methods for the large majority of their courses. Critics point out that lecturing is mainly a one-way method of communication

 was for the instructor to read from an original source to a class of students who took notes on the lecture. The reading from original sources evolved into the reading of glosses on an original and then more generally to lecture notes. Throughout much of history, the diffusion of knowledge via handwritten lecture notes was an essential element of academic life.

Even in the twentieth century the lecture notes taken by students, or prepared by a scholar for a lecture, have sometimes achieved wide circulation (see, for example, the genesis of Ferdinand de Saussure

's Cours de linguistique générale). Many lecturers were, and still are, accustomed to simply reading their own notes from the lectern for exactly that purpose. Nevertheless, modern lectures generally incorporate additional activities, e.g. writing on a chalk-board, exercises, class questions and discussions, or student presentations.

Research

Bligh, in What's the Use of Lectures? argues that lectures "represent a conception of education in which teachers who know give knowledge to students who do not and are therefore supposed to have nothing worth contributing." Based on his review of numerous studies, he concludes that lecturing is as effective, but not more effective, as any other teaching method in transmitting information. Nevertheless, lecturing is not the most effective method for promoting student thought, changing attitudes, or teaching behavioral skills.
Bligh summarises research on memory to show the significance of the meaningfulness of material on retention (Marks and Miller 1964) and the importance of immediate rehearsal of information (Bassey 1968). He relates his own research on arousal during lectures to suggest a decrement in attention during the first 25 minutes. Lloyd (1968) and Scerbo et al. (1992) showed that students take fewer and fewer notes as lectures proceed. Bligh shows that after a short break filled by buzz group discussion, attention will recover somewhat.
The largest section of Bligh's book is devoted to lecturing technique, particularly the organisation of lectures, how to make a point, the effectiveness of taking notes, the use of handouts and ways of obtaining feedback.
Early editions of the book contained a reply paid evaluation card. This research showed that the section on alternative teaching methods within lectures was the most highly praised.
