Context: In my IELTS class, I have to rewrite this sentence using a different structure:

There will be a sharp increase in the use of computers in classroom by the next decade.

My answer was:

By the next decade, computer usage in classroom will grow tremendously.

and the Answer Key was:

Classroom computer use will increase sharply by the next decade.

Did I use the word 'usage' correctly? Does my answer sound right and natural with you native speakers? Can 'use' and 'usage' be used interchangeably in this case?

I have looked up the 2 words in dictionaries and read this link as a reference but I still can't really tell what's right or wrong: https://english.stackexchange.com/questions/34712/use-vs-usage/34714#34714

Thank you!

You used usage correctly! Probably the answer key had a different response because the writer was trying to keep the two sentences as similar as possible. Your sentence had the same meaning, but slightly different words.

In general, usage and use (as a noun) are the same word and can be used in the same way. In the past, usage was a noun and use was only a verb. Over time, language changed and now they can both be nouns.


I would make one change to the starter sentence and your sentence though. These would sound more correct if there was an article or qualifier before the word classroom OR if classroom was plural instead (classrooms). So I would write this as "By the next decade, computer usage in the classroom will grow tremendously."

I recently wrote another answer about articles and why this is more correct.
