Much people will write about the nice thing about the teacher, and i think you have to write about wat the students expect about the teacher they like, and give the teacher any suggestion how to be liked by students, such as how to talk with students closely, so they'll understand n it makes easier for them to teach if they have a good social with student!

Hope this helps:)
