text: If students started to do online video conferencing, they would lack physical interaction. Some people might think that this is great for the shy students. But, if the teacher is not present the students wouldn't ask questions and the teacher wouldn't be able to physically help them with a problem. Also, the students wouldn't have one on one time with the teacher. Students need one on one time with the teacher so they can understand what they are learning and so that the teacher can help them individually. Furthermore, students need hands on learning. Hands on learning is important because it gives the students a general idea what the actual work is like so they can learn it and understand it better.
