3.Warm up: 

Defining the title and objectives of the lesson. 

        Look at the interactive board. (There are the pictures of different types of computer are shown in it: a supercomputer, a server, a desktop computer, a portable and handheld computers.)

What do you see in it? (Pupilsname of all types of computers).

What are the main differences between them? (They have different sizes; carry out different tasks, process data at different speeds).

Well, What about computers of our school labs?  Which type of computers are they? (They are desktop PCs.)

Which components of a desktop PC consist from? (a monitor, a keyboard, a system unit and a mouse).

Well, we learnt about their on previous lesson.

And there is a part of PC which includes many others small but the most important components inside.


Middle of the lesson

Activation of the knowledge. 

Look at my desk. They are here. 

And, what is a name of PC’s part where are fixed? (It is named a System unit.)

What are the main functions of the system unit? (It protects delicate electronics inside.)

Why they are here? What do you think? (Because we will learn about their.) 

What do you think? What is the title of our lesson today? (Students speak the thoughts of a title, and teacher generalizes and writes on the blackboard the Title).

Please write the title in your handout-paper. Internal computer devices.

  • Is this theme new for you?  (It is new, but we have spoken about it a little bit.)

Do you know some of these internal components?

May be, do you know their functions?

So tell me: What are we going to do at the lesson? 

(We will learn new computer’s components and their functions; 

   learn to assemble system unit

       develop our using & speaking skills).

Well Done!!!

Self-assessment before the lesson.

  • How well do you know this theme?  Mark yourself and stick the sticker nearby levels:  at the bottom, on my way, at the top. 

4. Comprehension:

New vocabulary.

At the lesson we will use new words. Look at Vocabulary, read after me in chorus.

Powersupply-  блок питания

Drive - дисковод

Adapter – карта , адаптер

Motherboard – материнская карта

Wires&cables– провода и шлейфы

Harddiskdrive (HDD– жесткий диск, винчестер

Central processing unit (CPU– центральныйпроцессор

Random access memory (RAM) – оперативнаяпамять (ОЗУ)

Network interface card (NIC) – сетеваякарта

Now write these words into your cards.

What is the English for «процессор»? ….etc.

What is the Russian for “power supply”? …. etc.

  Individual work “Match terms and their descriptions”. (Work in technological cards.)

Now please, turn on your monitors, find and open the folder virtual desktop and load the file Index.html. Click a button “Skip” and choose a bookmark “Explore”.

I will tell you a few words internal computer devices about. And you can see whole devices on your screens too. During my speech you will be filling table 2. You should write device’s names in the gaps. 

Are you ready?

Let’s start.

Internalcomputer devices (teacher speech).

Now you can see a system unit inside.

There are many small but the most important components in it. 

One of the main internal devices is Motherboard.It is the main printed circuit board that connects all the components of the computer. This is a sheet that holds all the circuitry to connect the various components of a computer system.

The next, Power supply. This internal computer device provides the needed voltage to power the various electronic circuits that make up the PC. 

CPU and heat sink fan.  Fan forces air over the heat sink. And over of fan CPU are fixed. This is the brains of thecomputer where most calculations take place. This is a piece of hardware that carries out the instructions of a program.

A permanent storage internal device is HDD – hard disk drive. This is a device that stores all the software installed on a computer as well as all the data files created and used by this software.  

There is other storage device which is fixed on a motherboard. It is random access memory - RAM.It is the storage space for data used by the operating system and other programs while the computer is in use. It is temporary memory computer uses to store anything temporary.

Adapter cards are installed on the motherboard to add functionality to your computer.

Video adaptersends data to a computer display.Its function is to generate output images to a display. 

Sound cardis an internal computer expansion card providing an audio input and output interface with connections for speakers, headphones, and microphone.

Network interface card is an adapter card used to connect your computer to a network.

We cannot image our desktop PC without Drives. They provide a way to pass files to and from the hard drive or to and from another computer. 

CD-drive is an optical device that reads and writes information to CDs and DVDs.  

Floppy drive is a magnetic drive that reads and writes information to floppy diskettes. 

Wires and cables provide power from a power source to some piece of motherboard and tools.  They transport electrical energy from the source of the electricity to the device.

Please, turn off monitors.

Check up the table. (Work in technological cards.)

Look at interactive board and check up the table.

If you have not mistaken, raise Green signal card.

If you have 1-2 errors, raise Blue signal card.

If you have 3 and more errors, raise Red signal card.

I will mark in Assessment Tables.

Make your choice.

Look under your keyboard. You can find a card-definition of functions internal computer’s devices. Read this definition. Identify the name of device. And write its name on the back of card. Then take your device from my desk.

If you have made right choice I will mark in Assessment Table.

Let’s start. (Student read card-definition; identify the name of device. And write its name on the back of card.)

5. Dynamic pause.

6. Comprehension: 

Virtual computer assembly. (Practice work.)

Do you want to do more difficult task? Well, for the next task you need a PC. Please, switch on your monitor.  And load a Learn bookmark in Virtual Desktop Model. I offer you to train in the assembly of the virtual desktop PC. But your time is limited. Just 10 minutes. Some of you, who will finish in time, will get “plus” in Assessment Table. 

Internal computer devices and their functions. (Pupils’s speeches.)

Now please, present you internal device to your classmates.

Who wants to start? If you have made right choice I will mark in Assessment Table.

(Pupils present internal devices.)

Extra work «True or False». (Work in technological cards.)

Decide if the sentences are  True (T) or False (F):

  • We use C: drive to open floppy disk.        T / F
  • The parts of computer you can touch are named HARDWARE.  T / F
  • The higher the speed of the CPU? The faster computer will run.   T / F
  • CPU means central processing unit.      T / F
  • We measured the RAM of the computer in megabytes.      T / F
  • Programs with a lot of graphics need a large RAM to run well. T / F

If you have made right choice I will mark in Assessment Table.

Assessments table.

Let’s look at Assessments table. 

Teacher says result of each student, comment it.

For example, “It is a good job. And today you have “5” or “4”. 

You don’t have any homework  today.

The lesson is over.

Thanks for your job.

Differentiation - how do you plan to provide more support? What tasks do you plan to put before more capable students?

Evaluation - how do you plan to check the level of mastering of the material by the students?

Health and safety practices

The lesson of computer science is not the first in the practice of students, so the teacher knows the abilities of students, assesses the level of knowledge, skills and skills. Students who are inactive in the lesson should be involved in the repetition of the above and encourage, encourage.

Check the knowledge of safety in the office of computer science can be a misunderstanding.

Individual answers to questions are evaluated by commenting on the answers.

Filling in the tables is a self-rating according to the criteria.

Rules of conduct in the office of informatics

At the lesson of computer science the student is obliged:

• Be careful, cautious, follow the instructions of the teacher accurately;

• Before carrying out the work, carefully study its description and understand the progress of the work;

• Do not keep items in the workplace that are not needed for the task;

• Do not leave instruments near the edge of the table, place them in such a way that it is convenient to conduct measurements without bending over the instruments;

• Tidy up your workplace after completion of work

Reflection on the lesson

The objectives of the lesson are achieved, the involvement in the work of the students is complete, all students showed interest in studying computer science

Summary evaluating 

What two aspects of the lesson went well (consider both teaching and learning)?

1: Demonstration of experiments attracted the attention of students, sparked interest in the study of computer science.

2: Encouragement by the word of the student who performed the right assignment.

What could help improve the lesson (consider both teaching and learning)?

1: Meet the students with each other.

2: Exercise by the students themselves.

What did I reveal during the lesson about the class or the achievements / difficulties of individual students, what should I look for in subsequent lessons?

All pupils are motivated for training, very inquisitive, have a wide outlook, but some students slowly and carelessly make notes in notebooks.
