ASEI PDSI Lesson Note On Computer Studies

Computer System

Subject: Computer Studies

Theme: Basic computer operation and concepts

Topic: Computer System

Sub Topic: Components of the computer system

Date: dd/mm/yyyy

Class: Basic Five

Duration: 35 Minutes

No of Learners: 30

Learning Objectives:

By the end of the lesson learners should be able to:
  1. Say what the computer system is.

    The computer system is an interrelated part of the computer working together to function as one.

  2. Identify the component of the computer system.

    1. Hardware
    2. Software
    3. Human ware / Peopleware / User

Rationale:

In the world today, every aspect of man make use of the computer, or is related and connected to the use of the computer. The human legs cannot walk without the brain neither can the brain do the walking without the legs, so also the computer. The computer can only perform its functions with the connection of some interrelated parts to form a computer system. Therefore, there is a need to teach our learners about the computers system since the computer is useless without its system.

Prerequisite/ Previous knowledge:

Learners have learnt what a computer is.

Learning Materials:

Computer hall / ICT centre in the School, Flashcard of various components of the computer, Picture of the computer system.

Reference Materials:

Foundation Computer Studies for Primary Schools' Book 5 by E. O. Adegbeyeni et al.
