Can a teacher see if a student views posted material on the Black Board?

My professor is all about participation. I was just wondering if she can tell if a student has read other students blogs or if a student is viewing the videos she posts. I am participating in the class just not talking a whole lot but I still review everyone else’s opinions and her material she makes available to us. I was just wondering if she can see that I am looking at these online on the black board.
