Read the following pasiune "curafiile until you feel you have a general understanding of it, and then an wer the question set at the end.

“Although, Britain's Open Univeníry, a new venense in higher education there, unly began teaching in 1971. its degrees are already recognized as equal in value to those of the other British uniremities: The Open ¿-ni- versity shares with them the aim of providing an education not inerely in strictly acadește fields bui in other stead of salon to the community

Basically, the Open University sches on correspondence-courses rather than on those methods traditionally i connected with university studies. Era studente study only in their own homes it has por al the usual laboratories, lecture-theatres of classroom. It has an academic staff xe highly qualified as a nonvial ebewhere. in the tyuen, Open University facilioea inciale wiint ou other univetiiy operates -a pragiamine of specint radin and television lessons.

in me cases, people who apply for places at the Open Unerly are si adults, rather than schoolteavers. and the great majority are fully employed, glühen in jobs or achouseway There are no full-time Open Unsy versity scadents at all, whereas at ordinary British univesides there are relatively few yare-time atuderits.

Students at the universities of Manchester, Oxford or Edkburgh are based in ose particular place, but the Open University's' teaching-activitie? cover the whole of Britain; there tino permanent centre for students. only administrative buildings. This means, of course, that there is no University Libay for students to use.

The Open Univenty does not follow the normal universtiy year, widelt cap from October to June. The Open University yes starts in January, and finishes with an examination in November. Furthermore, the your is 'nat divided into three terms, but, le conidered as one wake.

The administration of the Open thriversity - and it is of course a very complex task in compister-based; / to a fas, larger extent than is common in British higher education. As much as possible.of the routine work handled by compater, including (a'new departure) the making of some of the student's works, the stadion seals in lis misigament by post; the computer marka 1, and then operates, the meangements for sending in back to him. Such assignment is known in the Open Univicity as "CMA" or "computer-marked assign The Open University adminiskave offices are centralised in mpidly growing building In the New Town of Miton Keynes- an appropriate place for such an instituilon's headquarters.

The Open University's system of qualifying for a degree is unique among infish universities (thought"of common la America and other countries). Under this rymem, the student is įwarded pats for the courses he has successfully completed, and when he has collected enough potors is awarded the degree. This allows for asutter Open University innovation the student can study for as long as he likes before he graduates, id, he can work at has carth pace.

In the Open Univeritty the full-time teaching staff are truployed in a new colt ut on the whuict as: indelduals, but as members of a 'ccucie-tarm'; they prepare prisited texts, and television or radio programmer, for sending or broadcasting to the students Ebewhere, in Britain, the proportion of untremity staff so students ia shout one to eight; while in the Open Univerity the proponion is not full-time teacher to every one hundred and eighty part-time students – an kaportant factor where coses am concerned. And this is not the only way the Open University undergraduate la educated more cheaply for instance; expensive uni wly buldings are unnecessary, because riudents live and study in their own homes..
