Although open education and online education are both ways of adult education, both of them learn through distance online education. However, the advantages of open education are low tuition fees and high international recognition of certificates. If I plan to go abroad for development and need to work and study, I prefer to choose open education.
However, although the international popularity of online education is not high, its diploma belongs to key universities and has the aura of famous schools. It is enough to try on glasses in China. So the specific quality depends on personal choice.
There are two differences between these two kinds of education:
First, the concept is different: open education advocates the way of mutual recognition of credits between schools.
Second, different forms of education: online education is a form compatible with face-to-face, correspondence and self-examination; Open education is a learning mode which is centered on students and learning, not teachers.
