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.
