Edit] Etymology

The noun "lecture" dates from 14th century, meaning "action of reading, that which is read," from the Latin lectus, pp. of legere "to read." Its subsequent meaning as "a discourse on a given subject before an audience for purposes of instruction" is from the 16th century. The verb "to lecture" is attested from 1590. The noun "lectern" refers to the reading desk used by lecturers. In British English and several other languages the noun "lecture" must grammatically be the object of the verb "to read."

edit] History

A lecture at a medieval university (1350s) showing the lecturer reading a text from the lectern to students.

The practice in the medieval university 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.

The use of multimedia presentation software such as Microsoft PowerPoint has changed the form of lectures, e.g. video, graphics, websites, or prepared exercises may be included. Most commonly, however, only outlines composed of "bullet points" are presented. Critics such as Edward Tufte [1] contend that this style of lecture bombards the audience with unnecessary and possibly distracting or confusing graphics.
