Translate the following paragraph into Chinese.MOOCs are classes that are taught online to large numbers of students, with minimal involvement of professors. Typically, students watch short video lectures and complete assignments that are graded either by machines or by other students. That way a single professor can support a class with thousands of participants. Today the number of high-profile research institutions that present these courses has steadily risen. As college students continue to opt for more modern and flexible means of education, there is room for MOOCs to make major waves in the world of higher education. However, MOOCs aren’t a substitute for undergraduate education. The issue is that not many employers view the online courses as having the same amount of applicable information as an in-person class. In short, MOOCs are still viewed as courses for fun instead of real applicable learning.
