text: Now let's get to the second reason. If you were in class and you didn't understand a concept what would you do? If you could video conference then, after class you could conference with the teacher and talk to him/her about concepts you did not understand. If students could conference from home with their teacher about material that they didn't understand then grades would probably go up. I remember once I was in class and we were learning about quadratics and I did not fully understand it; so, I went to the test and I did not do well. If I had a conference, then I could have been able to understand the material and I could have done well on the test.
