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. Identify measures that will help to eliminate workstation hazards and where they cannot be eliminated, discuss how to minimise the risk. (e.g. evaluating display screen, adjusting the chair for comfort, avoiding potential slips and falls, re- positioning of devices, etc.)
