Hi, I'm Paul-Olivier Dehaye, professor of mathematics at the University of Zürich. This course is called Massive Teaching. It's a course about MOOCs. MOOCs in themselves are quite controversial, especially as far as pedagogy is concerned. In this course in the next three weeks, I want to give you some background about MOOCs but also widen this debate to include technology and business aspects of MOOCs. Like many other MOOCs, this MOOCs [sic] will be based around videos and some text surrounding those videos, including links to other references. Unlike other MOOCs, this MOOCs [sic] will try to be really interactive, and include a component coming from the students themselves. For these reasons I'll hold regular office hours almost everyday and the MOOC will also include an experimental section. This experimental section is meant to question the role of the teacher, as compared to the students, and try to put as much power into your hands rather than mine. For instance, the grading of this course will be mostly determined by you, actually, as part of one of those experiments. So, if you would like to join me, please go on and watch the other videos. I hope you'll learn a lot. I'm sure I will.
