Good writing is clear writing. To be clear, you need to know the
purpose of the writing assignment.
Like audience, purpose in a university setting is problematic. For most of us, we write in order to get good
grades.
While that is a sort of purpose, it is not a purpose that will help us
write clearly and communicate effectively.
Here are some purposes that will help us write clearly:
to inform
to show understanding
to persuade
to show results
to entertain
to analyze
Instructors will communicate the purpose of the writing assignment
explicitedly, implicitedly, or not at all. Regardless, it is up to you to write
with a purpose fully in mind.
Some writing has more than one purpose; decide the main purpose, and
then all other purposes should serve that purpose.
Know your purpose and write with purpose.
