The ted talk by Daphne Koller ‘What we're learning from online education?’ (2012 June) says that online education has a variety of benefits, for example, it can provide students around the world with free, convenient, high-quality and personalized education. Contrast to this opinion, the article ‘Who teaches university students? Contract teachers’ (2013 June) by Craig Mcfarlane claims that the completion rate of online education is extremely low, which means the students’ performance on online education is not desirable.
The fact that Mcfarlane gives in the article is about Harvard which is a university and it is aimed at teaching in classroom not online courses. Therefore, bad performances on the Harvard’s online course is reasonable
