Activities For Learning & Assessment Resources Progression
Starter (5mins) Pictures and Evaluating
videos health issues at
Show learners pictures of both a poorly set up workstation and an workstations
ergonomically designed one.
Ask them to identify what's wrong with the poorly set up workstation and
what improvements the ergonomic one offers.
Share performance indicators and introduce the lesson.
Main (35mins)
Engage learners in a discussion about potential health issues that can arise
from using a poorly designed workstation. This might include back pain, eye
strain, repetitive strain injuries, etc.
Ask learners if they or someone they know has ever experienced
discomfort or pain due to a poor workstation setup.
Present the ergonomic tools, such as an ergonomic keyboard and paper
stand.
Discuss their design features and how they help in preventing health issues.
If possible, have an actual ergonomic keyboard and paper stand for learners
to examine and try out.
Let learners compare them to traditional tools and discuss their
observations.
Divide learners into small groups. Each group is given a scenario of a person
experiencing a health issue due to their workstation.
They should discuss and present what ergonomic changes or tools they
would recommend to help alleviate the issue.
Assessment
1. What is ergonomics and why is it important for workstations?
2. Name two health issues that might arise from a poorly set up
workstation.
3. How does an ergonomic keyboard differ from a regular one?
4. Why might someone use a paper stand at their workstation?
Reflection (10mins)
Use peer discussion and effective questioning to find out from learners
what they have learnt during the lesson.
Take feedback from learners and summarize the lesson.

Core Competencies:
Learners can evaluate the importance of proper lighting when working

with computers and learn to set up an ideal lighting system to prevent

eye strain and other health issues.

Activities For Learning & Assessment Resources Progression
Starter (5mins) Pictures and Evaluating
videos health issues at
Begin with a simple demonstration. In a dim room, turn on a bright lamp workstations
positioned directly in front of the computer screen, creating glare.
Ask learners to observe and describe how comfortable it feels looking at
the screen. This will provide a tactile understanding of bad lighting practices.
Share performance indicators and introduce the lesson.
Main (35mins)
Discuss with learners the problems they observed from the starter activity.
Introduce the term "eye strain" and explain other symptoms like headaches,
dry eyes, etc.
Highlight the long-term effects of working with poor lighting.
Adjust the room's ambient light to a comfortable level.
Position the computer monitor so that windows and other light sources are
to the side, rather than in front or behind it.
Introduce the concept of "task lighting." Demonstrate using a desk lamp
that provides light to the workspace but doesn't create glare on the screen.
Discuss the benefits of adjustable or dimmable lights and the advantage of
using screen filters or monitor hoods in very bright environments.
If available, set up multiple lighting scenarios in different parts of the room
(e.g., a workstation near a window, one under a bright overhead light, one
using only task lighting).
Allow learners to rotate through these stations, observing which setup feels
the most comfortable and why.
Engage learners in a discussion on the benefits of natural light compared to
artificial light. Emphasize the importance of breaks and looking away from
the screen regularly, especially when working in non-ideal lighting
conditions.
Assessment
1. Why is glare on a computer screen problematic?
2. How should a computer monitor be positioned relative to windows or
bright light sources?
3. What is "task lighting," and why is it beneficial?
4. Why is natural light preferable when working on a computer?
Reflection (10mins)
Use peer discussion and effective questioning to find out from learners
what they have learnt during the lesson.
Take feedback from learners and summarize the lesson.
