What is the correct way of saying the sentence?
My teacher doesn't approve of the first example that I have listed.
My teacher doesn't approve the first example that I have listed.
Stretching the answer of Deadrat little further:
For Op's given examples:
My teacher doesn't approve of the first example that I have listed.
Means:
The teacher does not agree with the first example.
While
My teacher doesn't approve the first example that I have listed.
Means
The teacher doesn't accept the example.
Approve has the meaning of agreement, but with the preposition, it means agree with:
I approved of your decision.
Without the preposition, it means agree to:
The executives committee approved your budget.
In case it's not clear from the previous answers, you should used approve of in this context. If you're going for more of an "acceptance" meaning, just use accept:
The examiner didn't accept the first example that I have listed as a correct one.
