Pointing devices (e.g., mouse).
Image and document capture devices (e.g., scanner, digital camera).
Audio input devices (e.g., microphone).
Control/game input devices (e.g., joystick).
Card and code reading devices (e.g., card reader).
Pen-based input devices (e.g., light pen).

Keyboard

The keyboard is a text entry device used to type letters, numbers, and symbols into the computer.

The following are uses of a keyboard:

Typing documents and notes.
Entering numbers and data into tables.
Giving commands using keys such as Enter, Shift, and function keys.

Mouse

The mouse is a pointing device used to move the pointer and select items on the screen.

The following are uses of a mouse:

Pointing, clicking, and selecting icons or files.
Dragging and dropping items on the screen.
Scrolling through pages using the wheel (if available).

Scanner

A scanner is an input device that converts printed text or pictures into digital form for the computer.

The following are uses of a scanner:

Scanning documents into the computer for storage.
Digitizing pictures and printed images.
Supporting document sharing and record keeping.

Microphone

A microphone is an audio input device used to capture sound and voice into a computer.

The following are uses of a microphone:

Voice recording and narration.
Online communication and meetings.
Voice input for speech-to-text (where available).

Joystick

A joystick is a control input device used mainly for games and simulations.

The following are uses of a joystick:

Controlling movement in computer games.
Training simulations (e.g., driving or flight simulation).
Controlling certain specialised software tools.

Card Reader

A card reader is an input device that reads data stored on cards such as ATM cards, ID cards, or memory cards.

The following are uses of a card reader:

Reading ATM or identity card information in authorised systems.
Reading memory cards from cameras and phones.
Supporting access control and verification in organisations.

Light Pen

A light pen is a pen-like input device used to select or draw directly on a special screen.

The following are uses of a light pen:

Selecting items on a screen.
Drawing and simple design work on supported screens.
Precise pointing in graphics applications.

Digital Camera

A digital camera is an input device used to capture images and videos that can be transferred to a computer.

The following are uses of a digital camera:

Capturing pictures for documents and presentations.
Recording videos for learning and events.
Providing image data for editing and printing.

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher shows a keyboard and mouse and asks pupils to state what they are used for, then links responses to the meaning of input devices.
Pupils’ Activity: Pupils respond and observe the displayed devices.
Learning Point: Input devices are used to enter data and instructions into a computer.

Step 2: Meaning of Input Devices

Time: 6 minutes
Teaching Skill: Explanation
Teacher’s Activity: The teacher defines input devices and writes the definition on the board, giving simple examples.
Pupils’ Activity: Pupils copy the definition and mention examples they know.
Learning Point: An input device is hardware used for data entry into a computer system.

Step 3: Types of Input Devices

Time: 7 minutes
Teaching Skill: Classification
Teacher’s Activity: The teacher explains types of input devices and groups them by the kind of data entered (text, pointing, audio, image, control, card, pen-based).
Pupils’ Activity: Pupils copy the types and give one example for each type.
Learning Point: Input devices can be grouped by the kind of data they enter.

Step 4: Identification of Common Input Devices

Time: 8 minutes
Teaching Skill: Demonstration
Teacher’s Activity: The teacher displays input devices (or pictures) and guides pupils to name each: keyboard, mouse, scanner, microphone, joystick, card reader, light pen, digital camera.
Pupils’ Activity: Pupils identify and correctly name the devices displayed.
Learning Point: Common input devices have distinct shapes and functions.

Step 5: Uses of Input Devices

Time: 8 minutes
Teaching Skill: Explanation and Illustration
Teacher’s Activity: The teacher explains the use of each device and links each to real-life uses in school, home, offices, banks, and media work.

Learning Point: Each input device is designed for a specific kind of data entry.

Step 6: Class Activity (Matching and Grouping)

Time: 6 minutes
Teaching Skill: Guided Practice
Teacher’s Activity: The teacher gives pupils pictures/names of devices and instructs groups to match devices to their types and uses, then present answers.
Pupils’ Activity: Pupils work in groups, match correctly, and present findings.
Learning Point: Input devices can be identified, grouped, and linked to their uses.

Step 7: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

Define an input device.
List four input devices used for data entry.
State two uses of a scanner.
Mention one difference between a keyboard and a mouse.

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 8: Conclusion

Time: 0 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the definition, types, and examples of input devices and corrects misconceptions. Assignment: write eight input devices and state one use of each.
Pupils’ Activity: Pupils copy the summary and assignment.
Learning Point: Input devices are essential for entering different kinds of data into a computer.

Note for teachers using this lesson plan

Use real devices where available and clear pictures where devices are not available. Emphasize examinable points: definition, types, examples, and uses. Ensure pupils can correctly distinguish text entry devices, pointing devices, and capture devices, and reinforce safe handling of all computer equipment.
