Your arrow should point in the direction from the larger use case to the smaller (The main use case to the case that is part of the main one)
In this case, when a Student wants to see their grade or their information etc, they must log in - So, these use cases 'include' the login use case, so your teacher is correct.
Your version means that when an actor logs in, they must view their grades and see their information etc which doesn't make any sense.
