I think it’s better to do the presentation in front of the class. Because it can truly evaluate one’s performance. For example, if a student wants to get a good score, he has to put lots of effort into preparation and practice many times so that he or she can deliver the contents precisely coherently in front of the audience. It would easy for professors to assess who is well-prepared and who is not, and thus grade students impartially. Also, some students might cheat if they can film. For instance, some students would write down the script put it behind the camera so they sound very fluent and informative. That would be unfair to other student who put efforts doing it. (配有相关的视频)
