Girls, why is she glancing sideways at me?

Whenever she is called on by the teacher in class (to answer a subject related question or smth) and everyone (including me) looks at her while she speaks... she gives me those sideway glances

I mean, whole class is watching her, so am I

Then she is like: Briefly Glancing at me sideways, looking back to the teacher, glancing back at me and so on.

I don't know what I means :I
