text: Online classes or videos conferencing not catchs the students attention like a teacher makes it. For example, if you are taking online classes from home and you are at the midpart of one the lesson but you get hungry then, you left the lesson to get eat. After eat you say, "I want to go to the park," then, you, went to the park, so forged all about your lesson. Would you able to do the same during a normal day of class in the school? A teacher does not allows that a student left the school or to go to the park at the midpart of the class, while he is teaching because he wants to catch your attention to make you to learn more and morer. However, online classes or videos conferencing you can stop it and go or do whatever you want, then you lose knowledge abou it.
