A study of 11 MOOCs offered by MIT in spring 2014 "found that one in four (28.0 percent) respondents [i.e. learners] identified as past or present teachers." "Although they represent only 4.5 percent of the nearly 250,000 enrollees, responding teachers generated 22.4 percent of all discussion forum comments." Over 70% of teachers responding to exit surveys agreed they might use the matyerial in their teaching. The authors identify the value of teachers taking MOOCs (since they appear to be very participative) and see at as a positive thing "We believe teacher participants in MOOCS are a resource to respect and value, with the potential of further enriching the MOOC experience for participants". There are also obvious implications to do with teachers' self development, and their wish to re-use material encountered in the MOOCs.
