According to a new study out of UNLV, students do better in school if their teacher is good looking.
The researchers had some students listen to an audio recording of a lecture and look at the photo of the person they thought was giving it.
Some of them saw a photo of an attractive teacher, and some of them saw an unattractive teacher.
And when they took a test on the lecture afterwards, the kids who thought they had a good-looking teacher got better scores. They also gave the teacher better reviews.
