Learning Objectives

Indicator: B8.1.3.1.2 - Discuss safety measures in risk reduction at workstations

By the end of the lesson, learners can:

Identify at least three safety measures that reduce risk at a computer workstation.
Demonstrate the correct volume level for using speakers and earpieces, and explain why excessive volume damages hearing.
Explain how screen protectors and anti-glare spectacles reduce eye strain, and demonstrate their proper use.
Demonstrate the correct way to connect multiple devices to a power source using a trailing multi-socket unit instead of plug adapters.
Discuss why overloaded electric sockets are a fire hazard and how proper socket use reduces risk in the computer laboratory and at home.

Source document note: The official curriculum document has a fault in this entry, so the curriculum text above is transcribed exactly as printed:

sub strand name - printed 'INTHE' with no space. The JHS document never prints the spaced form, but NaCCA's own primary Computing curriculum names the same sub-strand 'TECHNOLOGY IN THE COMMUNITY' (b4/b5/b6-computing.csv). sub_strand_name becomes the lesson topic a teacher sees, so the missing space is closed.

Exemplars (from the NaCCA curriculum)

1. Demonstrate the use of appropriate volumes when using speakers and earpieces.
2. Demonstrate the use of screen protectors/spectacles to control the amount of light received by our eyes.
3. Illustrate how not to overload electric sockets but use trailing multi-socket units rather than plug adapters.
