text: The most important characteristic of a teacher is their ability to help students understand subject material. Most teachers use some form of conversational engagement because it is the most effective way of sharing information with another individual. This ranges from teacher led PowerPoint presentations to group work among peers. Without a physical classroom, teachers lose this ability. Now, they are forced to present information in a single way and hope that it is reaching everyone. Teaching methods shouldn't be based on hope, they should have solid evidence for success. Also, distance learning removes a student's ability to get after school help. In a physical class, a confused student can simply ask to stay after school for extra help, and receive immediate feedback. Distance learning makes getting extra help harder. Now, a student will have to sent an email, wait for a response, find transportation, and take many more steps just to get further explanation. Realistically, a teacher will just redirect students to a self-learning site, such as Khan Academy, and force a student to help themselves. This defeats the point of having a teacher in the first place. Moreover, some students simply learn better when they can talk to a real person.
