Lecture hall

in 1233 The use of lectures at universities dates back to the middle ages. A variety of different rooms and halls may have been used for lectures – one of the earliest images of a lecture shows Henry of Germany giving a law lecture at the University of Bologna in 1233, speaking from what appears to be a pulpit. interpreted as lecture theatres Lecture theatres may go back further than this, however, with archaeological excavations at Kom El Deka, near Alexandria, having uncovered a complex of U-shaped auditoria that have been interpreted as lecture theatres from the classical period. gives all seats a clear view of the dissection table Tiered lecture theatres developed in Renaissance Italy, where they were used for teaching anatomy. The earliest purpose-built lecture theatre of the modern era was in Padua in 1594, but the idea spread quickly with a lecture theatre being built in Leiden in 1597 and at the Barber-Surgeons Hall in London in 1636, designed by Inigo Jones. The steep rake of these lecture theatres enabled students to see the dissection table and was copied by scientific lecture theatres to ensure the demonstration bench could be seen. The "Harvard-style" lecture theatre developed in the late 19th century at Harvard Law School. These had a shallower rake than traditional lectures theatres and placed the seating in a U-shape rather than in arced or semi-circular rows, promoting exchanges between lecturers and students. ==Types==

Lecture theatres come in various types, suiting different pedagogies and space restrictions. These include: • Tiered lecture theatre: the traditional lecture theatre, with rows of tiered seats enabling the speaker and screens or boards to be seen by large numbers of people. Example: the Gillis lecture theatre at Balliol College, Oxford. • Harvard-style or horseshoe lecture theatre: U-shaped arrangement of seats on shallow tiers, designed to promote interaction between students and the lecturer. • Retractable lecture theatre: a flat room that can be converted to a tiered lecture theatre by deploying retractable seating, allowing for a variety of uses. Example: the Fonteyn Ballroom in Dunelm House at Durham University. • Collaborative lecture theatre: a lecture theatre with a shallow tiers designed so that seats can be turned to form collaborative booths for group work or forwards for use as a normal lecture theatre. Example: three lecture theatres in the Roger Stevens building at the University of Leeds. ==Technology==

The original conception of lecture theatres was as spaces for listening to a speaker talk or for viewing a scientific demonstration. The first introduction of technology was writing boards – originally chalk boards but now normally whiteboards. This was supplemented with projectors – originally slide projectors and now normally digital projectors attached to a computer. Computer systems control the audio-visual technology and may also give control of the lighting level in the room. Microphones and speakers are commonly used in larger lecture theatres to ensure the speaker can be heard. Lecture capture technology allows for lectures to be recorded and watched later, or to be attended virtually when linked with a video conferencing system. Networking of lecture theatres can allow a lecture to be shown in multiple rooms. == References ==
