Question

online teaching do a lot of harm to the students essay​

Answer 1

Answer:

Harder to form study groups: It’s also harder for students to connect with each other. That has social disadvantages, and from an educational standpoint it makes it harder for students to meet and form study groups. There are tools that allow online collaboration among students, and they can arrange to meet in person if they are on campus, but it’s not the same.

Office hours not as effective online: Office hours conducted in a chat room or by email are not as effective as traditional office hours. The main problem is technological. In my office I can easily go to the whiteboard, draw graphs, write mathematical equations, and so on, when answering questions. But online whiteboards are terrible for drawing graphs and writing equations on the fly. I can still hold traditional in-person office hours for on-campus students, but that is not possible for large-scale online classes with a substantial number of off-campus students.

Machine graded exams and homework: I do not like multiple-choice exams, especially for upper division courses. Essay exams are much better. It’s still possible to give essay exams and homework problems for online classes with limited enrollment, but grading written work is problematic when these courses are scaled up to hundreds of students to reduce costs. It could be done with enough grading help, but that would largely eliminate the cost advantage these courses offer.

Here are the positive aspects, and some of the ways the negatives discussed above can be overcome:

Different way of asking questions: Although students cannot ask questions in the same way they can in a traditional classroom setting, all is not lost. When students have questions during a video lecture, they can hit the pause button, rewind the video, and watch the section again. That is often enough to clear up the confusion. If not, while the video is paused they can read the book for clarification, search for an explanation using Google, or, as a last resort, save the question for office hours.
