UNIVERSITY EDUCATION IN GREAT BRITAIN
There are
more than 60 universities in Britain. . But not all universities are equal.
They differ from one another in history, tradition, academic organisation. Not all
British universities have a well-known reputation. Oxford and Cambridge, the
oldest universities, are world known for their academic excellence.The
University of London has the size and breadth to rank among the UK's top
universities. A university usually consists of colleges. The departments of the
colleges are organised into faculties.
University
teaching in the UK differs greatly at both undergraduate and postgraduate
levels from that in many other countries. An undergraduate programme consists of
a series of lectures, seminars, tutorials and laboratory classes which in total
account for about 15 hours per week.
Following a
particular programme students take series of lecture courses which may last one
academic term or the whole year. Associated with each lecture course are
seminars, tutorials, laboratory classes which illustrate the topics presented
in the lectures.
Lectures
are given to large groups of students (from 20 to 200). Seminars and tutorials
are much smaller than lecture classes and in some departments саn be one a one-to-one basis (one
member of staff and one student).
Students
prepare work in advance for seminars and tutorials. And this can take the form
of a topic for discussion by writing essays or by solving problems.
Lectures, seminars and tutorials are all one
hour in length, laboratory classes last two or three hours. Each student has a
tutor whom he can consult on any matter whether academic or personal.
The academic
year is split into three terms. Formal teaching takes place in the first two
terms which last for twenty four weeks in total. The third term is reserved
for classes and examinations and lasts for six weeks.
Universities
teach in all major subject areas: arts, science, law, engineering, medicine,
social sciences.
University
staff are chosen for the best knowledge in their subject. The teaching
encourages students to learn in the most effective way. University degree
courses extend from three to four years. After three years of-,, study at the
University graduates will leave with the Degree of Bachelor of Arts or Science.
They can continue to take their Master's Degree and then the Doctor's Degree.
