It is very easy to get a misunderstand the word computing when it has more than one meaning;
Computing (kuh m-pyoot-ing)

So computing as a term existed before the computer. It is the very process of thinking about a solution as well as (in the modern day language) the study of the computer itself and the use of the computer. This gives it at least 3 chances of being misinterpreted.
In Computing in schools then we need to make sure that we consider all three aspects when drawing up a curriculum. Sometimes there is a tendency to think of computing as being ‘just programming’ or ‘just about computers’ and the process of involving computers is so much more; more akin to the process of problem solving that goes into basic solution of engineering problems (as found in the coursework elements of ICT/Computing or the Technology syllabus).
So next time you find yourself wondering ‘What is computing?’ Try asking instead the question ‘Why do I need a computer?’
