Lecture

A lecture is a talk on a particular subject given in order to teach people about that subject, for example by a university or college teacher.

Criticised by educators and methodologists for its typical one-way communication, lectures have nevertheless survived in academia, mainly as a quick, cheap and efficient way of introducing large numbers of students to a particular field of study. In past centuries the diffusion of scientific knowledge via handwritten lecture notes was an essential element of academic life (see, for example, the genesis of Ferdinand de Saussure's Cours de linguistique générale); professors were used to actually reading out from their own notes for exactly that purpose. Today, the use of multimedia presentation software such as Microsoft PowerPoint has changed the very essence of lectures, with listeners, as critics put it, being bombarded with all sorts of unnecessary and confusing visual aid.

Other forms of academic teaching include seminars, workshops, and tutorials, while in schools the prevalent mode of student-teacher interaction is lessons.
