- Charts showing the IPO cycle
- A functional computer system
- Flash cards showing examples of data
- Whiteboard and markers
Rationale for the Lesson
Understanding how computers work as information processing machines helps children know how everyday devices collect and use data.
Prerequisite/Previous Knowledge
Pupils have previously seen and used basic computer devices like a keyboard or mouse and understand that computers help in doing tasks.
Lesson Content
Computer As An Information Processing Machine
A computer is a machine that collects, processes, and gives back information. It uses a special method called the IPO process. IPO means Input, Process, and Output.
Meaning of IPO
IPO stands for Input, Process, and Output. This is how computers handle data.
The following are the meanings:
- Input is when the computer collects data
- Process is when the computer works on the data
- Output is when the computer gives the result
Input Devices
Input devices are tools we use to give data to the computer. Examples are:
- Keyboard
- Mouse
- Microphone
- Scanner
- Joystick
Examples of Data Collected
The computer collects many types of data using input devices. These include:
- Letters typed on a keyboard
- Pictures scanned by a scanner
- Voices recorded with a microphone
- Movements from a joystick
- Clicks from a mouse
Teaching Methods
Discussion, Lecture, Demonstration, Explanation, Visual Aids, Group Work
Instructional Procedures
| Content Development | Time | Teaching Skills | Teacher’s Activity | Pupils’ Activity | Learning Point |
|---|---|---|---|---|---|
| Step 1: Introduction | 5 mins | Set Induction | The teacher shows a keyboard and asks, “What do we use this for?” Then tells a short story of how computers help people type and talk. | Pupils respond to questions and listen to the story. | Pupils become curious about how computers work. |
| Step 2: Meaning of IPO | 7 mins | Explanation | The teacher explains the IPO model using diagrams and gives real-life examples. | Pupils listen and observe the charts. | Pupils understand what IPO means. |
| Step 3: Input Devices | 7 mins | Demonstration | The teacher shows and names different input devices and describes their functions. | Pupils identify and touch real devices. | Pupils learn the names and uses of input devices. |
| Step 4: Examples of Data Collected | 6 mins | Explanation | The teacher describes different data collected using input devices. | Pupils mention examples and take turns demonstrating. | Pupils recognize different kinds of data. |
| Note Taking | 5 mins | Writing | The teacher dictates the note and writes on the board. | Pupils copy the note into their books. | Pupils write key facts for revision. |
| Evaluation | 5 mins | Assessment | The teacher asks oral questions and practical tasks based on the lesson. | Pupils answer questions and perform tasks. | Pupils show understanding of the topic. |
| Conclusion | 5 mins | Cognitive and Instructional Closure | The teacher summarizes the lesson and connects it to future learning on processing and output. Encourages pupils to notice input devices around them. | Pupils listen and ask final questions. | Pupils reflect on what they learned. |
Lesson Keywords
- Computer: A machine that processes information
- Input: The data we give to a computer
- Process: The work the computer does on data
- Output: The result the computer gives
- Device: A tool used with the computer
Lesson Evaluation
To evaluate the learning, the teacher asks pupils to:
- What is IPO in computers?
- Name three input devices.
- Give two examples of data a computer can collect.
- What is the work of the keyboard?
- Show how you use the mouse to give data.
Differentiation
Teacher uses real objects, visual aids, and group work to support all learning styles and ensure every pupil understands the topic.
Note for teachers using this lesson plan
Ensure pupils have hands-on interaction with real or simulated input devices. Use storytelling and visual aids to simplify complex ideas.
