text: Students attending to school can be controlled by teachers, students with control wouldn't be as distracted as those who have no control and can do a lot of things without being caught. The students that get distracted will be more likely to get worst grades than the ones that attend to school and are controlled by teachers. Online or video conferencing depends on the internet and device that you are using, there's people that can't afford that, and people that can, also have problems. If the power of the city or district goes out, it means that also people using video conferences wouldn't have electricity in the house, making impossible to attend classes from home. Even if the power is on, some people have slow internet connection, and an online server wit a hole class working at the same time, will make that person's video conference go slow or lag, witch means that the same person would be missing information, making his or her grades go down grades go down and it wouldn't benefit him or her.
