Ход урока

1. Организационный момент

Студенты сидят в компьютерном классе. Звучит спокойная музыка для снятия напряженности, настроя на работу. На фоне музыки слова преподавателя: Dear students! I’m glad to meet you at our Internet coffee

2. Речевая подготовка

На доске тема “The Development of Information Technology” (Слайд 1. Приложение 1)

Teacher: “Computers aren’t intelligent, they only think they are”

Teacher: What does it mean?

Student 1: Computer is a machine. It can’t think. People operate it.

Student 2: People write programs. Computer can’t work without programs.

Student 3: We can do a lot of things on computers but we cant do they without software

Let’s speak about the history of computers.

На интерактивной доске слайды и даты (Приложение 1)

Студенты сообщают информацию из истории компьютеров.

1883 Charles Babbage, in England, developed the principles of what later became the electronic computer.

1946 ENIAC, the first electronic computer, was produced in the USA. It weighed 30 tonnes, and was 5.5 meters high and 24 meters long.

1953 Approximately 100 computers were in use worldwide.

1960 s It became possible to make electronic machines much smaller by using transistors and integrated circuits.

1969 The United States Defense Department established ARPAnet. This was the beginning of the Internet. The Internet allows messages to be sent from one computer to another.

1977 The Apple Computer Company produced the Apple II and millions of people bought their first computer.

1981 IBM produced the Personal Computer. IBM ‘clones’ made computers much cheaper.

1984 Apple produced the Macintosh computer with an easy-to-use graphic interface.

1990 The World Wide Web was developed for scientists to exchange information. The WWW is a system which allows computers to communicate with each other, and exchange graphics and sound as well as that, through the Internet.

1991 CD ROMs first appeared.

1993 The Internet became available to anybody who had a computer, a modem and a telephone.

The Development of Information Technology

International technology, IT, changed our society. It comprises electronic computer technology and telecommunication technology. Its development originated from fundamental scientific inventions in physics.

The development of electronic computer technology started with the invention of the integrated circuit in 1960 and the microprocessor in 1970s.The number of components on a chip was rather large and the machines were really big. Today chips with millions of separate components allow the creation of a complete microprocessor.

Chip development has been matched by dynamic and powerful developments in telecommunication technology. Ultra-rapid transistors and semiconductor lasers based on heterostructures of semiconductors are playing a decisive part in modern telecommunications.

Electronic components are made of semiconductors, i.e. materials that is something between a conductor and an insulator. Most semiconductor components are made of silicon. A semiconductor, consisting of several thin layers with different band gaps, is termed a heterostructured semiconductor. In the 70-s heterostructure lasers became able to work at room temperature. This made possible fibre-optic communications.

The invention of the transistor in 1947 is usually taken to mark the start of the development of modern semiconductor technology. A transistor is smaller, more reliable and less energy-consuming than the radio valve, which thus lost its importance. Ten years later many elements were fabricated in one and of the same basic material, and in one piece. This invention is more technical and led to development of apparatus and instruments.

8. Teacher: let’s check if you’ve understood everything. If you agree – write “+”
If you disagree write “-”

12. Let’s have fun

Teacher: words often change their meaning to suit the new realities of life. The use of computers has started an intensive process of change, which is still going on. Much of Russian speaker. This poem proves that it is much the same to a native English speaker.

Remember When…
A computer was something on TV
(frankly speaking it was rarely seen)
a site was only a place
and a window was something you hated to clean

Memory was something you lost with age
a keyboard on piano was making a sound
a program was a TV show
and the net was for playing around

A mouse pad was where a mouse lived
paste you did with glue
a web was a spider’s home
and a virus was the flu

I guess I’II stick to my pad and paper
and the memory in my head
I hear nobody’s been killed in a computer crash
but when it happens they wish they were dead
