text: Students should be able to communicate with their teacher in person if they need help with anything. Video calling doesn't help the students the same way talking to the teachers in person can. If a student need help on a math problem looking at the problem in front of you can help you understand it better then looking at it from a computer screen. Even though teachers can help gift you a good education from inside the classroom, you can receive even better education from the teacher helping you online and from some trustful websites.
