Compared to the past, online education is spreading quickly and it is becoming valuable more and more since the COVID epidemic. Generally online edication has merits and demerits. These have been discussed over different period.Some people think that physical courses in a university are worth more than online courses, other people think online couses conpensate for phisical ones.
The first advantage of online education is that students are not limited by time and place. it makes it possible to watch offered videos anytime and anyplace freely.Moreover, it is very convenient and innovative for students who couldn’t understand everything by just listening once. Because they can watch videos again and again when they want to.
Secondly, online lectures make the method of grade evaluation brief and clear. For example, with the introduction of Internet on education, the management of students’grades has transfered to an online platform. It is easy to check them with their own devices.
However, online lectures have a significant weak point. FRom perspective of the experience,online learning will be said to be inferior to face to face lectures. For instance the contents of lectures is less memorable for students,bacouse they can not learn through communication with teachers and other classmates unlike physical lectures, thus teachers become only video providers, which causes decline of an academic ability of students.In addition, As teachers could not monitor individual students strictly,they mostly give scores based only on the result of reports and exams without attitude in the class.
