### Lesson Procedure
#### Introduction (10 minutes)
1. **Greeting and Introduction:**
- Greet the students warmly and briefly introduce the topic of the lesson.
- "Today we will learn about the classification of computers. Have you ever wondered how many types of computers exist and how they are different from one another?"
2. **Engage:**
- Show a short, engaging video clip that briefly demonstrates different types of computers (e.g., smartphones, tablets, laptops, desktops, and mainframes).
- Ask quick, informal questions to gauge students' prior knowledge.
- "Can anyone name any types of computer you saw in the video?"

#### Instruction (20 minutes)
1. **Direct Instruction:**
- Explain that computers can be classified in different ways:
- **By Size:**
- Microcomputers (e.g., personal computers like desktops and laptops)
- Minicomputers (e.g., mid-range servers)
- Mainframe Computers (e.g., large servers used by large organizations)
- Supercomputers (e.g., powerful machines used for complex calculations like weather forecasting)
- **By Functionality:**
- Personal Computers (PCs)
- Workstations
- Servers
- Embedded Systems (computers incorporated into other devices such as smartphones, smart TVs)
2. **Visual Aids:**
- Use PowerPoint slides with images and descriptions of each type of computer.
- Make comparisons to help students understand, for example: “Laptops are portable, unlike desktops that usually stay in one place.”
3. **Interactive Discussion:**
- Involve students by asking them questions about the computers they have used or seen.
- "Who has used a tablet before? How is it different from using a desktop computer?"

#### Guided Practice (15 minutes)
1. **Class Activity:**
- Hand out worksheets containing different pictures of computers.
- Ask students to classify these computers into the correct categories based on the criteria discussed.
- Group students into pairs or small groups to encourage discussion and teamwork.
2. **Feedback:**
- Review the answers as a class by going through the worksheet together on the whiteboard or projector.
- Provide positive reinforcement and correct any misunderstandings.
---
#### Independent Practice (10 minutes)
1. **Individual Task:**
- Give students a scenario-based worksheet:
- “Imagine you are starting a new company. What type of computer would you need and why?”
- Encourage them to write a short paragraph recommending a type of computer based on the needs described in the scenario.
---
#### Assessment (5 minutes)
1. **Quick Quiz:**
- Conduct a quick verbal quiz or multiple-choice questions about the classification of computers.
- Example questions: “Which type of computer is the most powerful and used for scientific calculations? a) Microcomputer b) Mainframe c) Supercomputer”
2. **Review and Recap:**
- Summarize the key points of the lesson.
- “Today, we learned that computers can be classified by size and functionality. We talked about microcomputers, mainframe computers, and even supercomputers.”
---
#### Conclusion (Additional 5 minutes)
- **Homework Assignment:**
- Ask students to draw and label their favorite type of computer and write a few sentences about what it is used for.
- **Q&A Session:**
- Allow students to ask any questions they may still have.
- **Closure:**
- Thank the students for their participation and provide encouraging remarks about their learning journey in ICT.
---
#### Follow-Up:
- Plan a field trip to a computer lab or museum if possible.
- Arrange a guest speaker session with an IT professional to talk about different uses and types of computers in the industry.
