Subject: Information Communication Technology ICT
Lesson Topic: Know and understand the causes of these health issues and strategies for preventing them
Learning Objective/s:
  • Describe common health issues linked to ICT use.
  • Identify the primary causes of these health issues.
  • Explain at least three prevention strategies, including the 20‑20‑20 rule and ergonomic adjustments.
  • Apply ergonomic principles to set up a safe workstation.
  • Evaluate personal habits and create a micro‑break schedule.
Materials Needed:
  • Projector or interactive whiteboard
  • Computer with internet access
  • Printed handout of ergonomic checklist
  • Slide presentation summarising health issues and strategies
  • Worksheet for review questions
  • Optional ergonomic accessories (adjustable chair, footrest) for demonstration
 Introduction:

Begin with a quick poll asking students how many hours they spend on a computer each day, then share a striking statistic about eye‑strain prevalence. Connect this to prior lessons on safe ICT use and explain that today they will explore why these problems occur and how to prevent them. Success will be measured by their ability to list causes, describe the 20‑20‑20 rule, and design a personal micro‑break plan.
Lesson Structure:
  1. Do‑Now (5') – Students record their daily screen time on a sticky note and place it on the board.
  2. Mini‑lecture (10') – Overview of health issues and primary causes using slides and an ergonomic diagram.
  3. Guided discussion (8') – Students match causes to issues using the summary table.
  4. Demonstration (12') – Set up an ergonomic workstation; model the 20‑20‑20 rule and micro‑break stretches.
  5. Group activity (15') – Teams create a 5‑minute daily routine incorporating breaks and ergonomic tips; complete worksheet.
  6. Review Q&A (5') – Teacher checks understanding with three of the review questions.
  7. Exit ticket (5') – Students write one personal action they will implement.
Conclusion:

Summarise the key causes and the most effective prevention strategies discussed. Invite a few volunteers to share their micro‑break routine as a quick recall. For the exit ticket, students note one ergonomic change they will make at home. Homework: complete the worksheet on designing an ergonomic workstation and bring a photo of their setup.
