The document provides a detailed lesson plan about computers that includes objectives, subject matter, methodology, and evaluation sections. It aims to teach students about the basic parts and functions of a computer by describing the central processing unit, memory, storage, input and output devices. The lesson plan involves student participation through question and answer activities to reinforce learning about topics like the history of computers and how components inside the computer base unit work together.

A. Preparatory Activity
a) Review
Good morningclasshowisyour day?
Didyou eatyour breakfast?
Good,it isimportantto have a breakfastbefore
startingyouday
Let’smove on,what have we discussedlast
time?
Verygoodclass
Is there anyquestion?
Ok,as part of your reviewletusanswerthe
followingquestions
What isthe firstor the earliestcomputerthatis
usedinChina? Commonlyusedasa calculator
for businessman

b) Motivation
(showthe picture of a computer)
Nowclasswhat isthis?
Verygood
(pointoutthe monitor)
What do youcall this part of the computer?
Verygood
(pointoutthe mouse)
Andhowabout thisone?
If there are twomouse or more?
Verygood
c) Lecture
So those are the commonparts of the
computerandtheyare alsoknownas
peripherals.

data can be readfromdiscs anddigital
discs(DVD).Datacan be storedinremovable
diskor removable storage (CDs,DVDs,Floppy
disk,flashdrive).
Peripherals like keyboard,mouse andjoystick
are inputdevicesthatare usedtoenter
instructionin the computer.
Can yougive some more examplesof input
device?
Verygood
There are a lotof input devicesanditis too
manyto mention.
If there are inputdevicesthenthere mustbe an
outputdevices
Can youtell me whatthose devicesare?
Verygood
Outputdevicesare usedtodisplayinformation
on a screenor printedform(hardcopy);to
produce sound;or to obeyinstructionsfrom
the computeron robotics.
(give some examplesof outputdevices)
Aside frominputandoutputdevicesthere are
alsodevicesthatare usedfor communications,
Andthisdevice are called Networkdevices,it
allowscomputertocommunicate withother
computeror to connectwiththe internet
