Interactive Rubric for Written Communication: 7.2.1. Apostrophes

This guide will help you understand common conventions of academic writing and the application of marking rubrics

Definition (formal)

Apostrophes (i.e., ') are marks used to indicate ownership (e.g., teacher’s pedagogy) or intentional omission of a letter (e.g., didn’t) to make a contraction.

Definition (informal)

Apostrophe: A mark to show that something is owned or a letter is missing.


For example, the following sentence omits a possessive apostrophe (students should be students') and contains an unnecessary contraction (it’s could be it is).

While it's not the only factor, the environment that a teacher creates can influence students behaviour.
