Well, Stargirl does try to change to become popular. She enters the Arizona state oratorical contest, hoping that if she wins, then the other students will think she's great. Unfortunately, it doesn't quite turn out like that, and not because Stargirl failed to win. On the contrary, she storms the competition. Her winning speech receives rapturous applause from the audience, and she ends up on the front page of the local newspaper.
But when Stargirl returns to school, far from being hailed as a conquering hero by the other kids, she's roundly ignored by them. It's almost like she doesn't exist. The only people waiting to greet her as she arrives in the school parking lot are Dori and a couple of teachers.
The moral of this episode would seem to be that you should always be true to herself. Stargirl certainly takes this lesson to heart after winning the oratorical contest. From now on, she's going to be her normal kooky self instead of trying to fit in and be popular.
