Is it right to say "do correction" (especially for teachers)?

When a student makes a mistake or an error in his/her book, we should put a remark - "PLEASE MAKE A CORRECTION."
Informally, we can say 'Please do a correction'.
If there is more than one error, they need to make corrections.

So, it's wrong to say or write 'please do correction'.

#'Correction' is a countable noun
However, it can also be an uncountable noun if we refer to the general action of 'making something right'.
For example;
'Sentence correction is needed in his essay.'
'There are a few types of geometric correction.'
