#### Guided Practice (20 minutes):
1. **Hands-on Component Identification**:
- Divide students into small groups.
- Provide each group with either models or actual parts of steering system components.
- Have each group identify and explain the function of each component.
2. **Troubleshooting Basics**:
- Discuss common problems such as steering wheel vibration, stiffness, and misalignment.
- Demonstrate basic troubleshooting techniques and safety precautions.
---
#### Independent Practice (20 minutes):
1. **Worksheet Activity**:
- Distribute a worksheet with questions related to the steering system, including identification, functionality, and troubleshooting.
- Allow students to work individually or in pairs to complete the worksheet.
2. **Hands-on Practice**:
- If facilities permit, let students practice identifying components on actual vehicles under supervision.

#### Conclusion (10 minutes):
1. **Review and Recap**:
- Summarize the key points covered in the lesson.
- Revisit the objectives to ensure they were met.
2. **Q&A Session**:
- Open the floor for any final questions from the students.
3. **Homework Assignment**:
- Provide a short assignment or reading material to reinforce the lesson.
- Example: Have students research the latest advancements in steering systems and write a short report.
---
#### Assessment:
- Evaluate students’ understanding through their participation in guided practice.
- Review and grade the worksheet activity.
- Conduct a short quiz in the next class, if needed.
---
#### Additional Notes:
- Ensure all safety protocols are followed when handling actual parts.
- Be prepared for varying levels of understanding and provide additional support where needed.
- Incorporate various teaching aids (videos, diagrams, physical models) to cater to different learning styles.
