Lesson Plan

• Describe the common health issues linked to prolonged ICT use (RSI, back problems, eye strain, headaches).
• Identify symptoms, causes and preventive actions for each issue.
• Demonstrate an ergonomic workstation setup and appropriate break routines.
• Apply the 20‑20‑20 rule and correct posture to reduce eye strain and musculoskeletal discomfort.

• Projector and screen
• Computer with internet access
• Ergonomic workstation diagram handout
• Printable worksheet with health‑issue scenarios
• Timer or smartphone for break intervals
• Sticky notes for student reflections

Begin with a quick poll: how many students have felt discomfort after a long computer session. Explain that extensive ICT use can impact our bodies and minds, leading to RSI, back pain, eye strain and headaches. State that by the end of the lesson they will be able to recognise symptoms, understand causes and set up an ergonomic workspace.

1. Do‑Now (5') – Students list any discomfort experienced while using devices and share briefly.
2. Mini‑lecture (10') – Teacher presents the four health issues using slides and the ergonomic diagram.
3. Group activity (15') – Teams match symptoms to causes and preventive actions on a worksheet.
4. Demonstration (10') – Show correct chair, monitor and keyboard positioning; students adjust their own stations.
5. Break practice (5') – Guided 20‑20‑20 eye break and simple hand‑arm stretches.
6. Whole‑class discussion (5') – Students reflect on how the preventive steps can be applied daily and write one personal action on a sticky note.
7. Exit ticket (5') – Quick 3‑question quiz on symptoms and prevention.

Recap the four health issues and the key preventive measures practiced today. Collect exit tickets to check understanding. For homework, ask students to keep a one‑day log of their break and posture habits and bring their observations to the next lesson.
