While we have all seen articles and programs about online
learning, nothing grabbed me until I listened to Diane Rehm
moderating a panel of people talking about how online
courses may fit in higher education’s future.
One of the major take-aways is the concept of MOOCS.
I listened hard and near the end the panelists began describing
this concept of Massive Open Online Courses that is taking
off at universities and some private companies. [See the
Rehm discussion page for some detail and also Coursera which
describes courses being offered this fall.]
Now what kinds of courses are offered this way, in STEM
fields…? This site  lists 500 such offerings that may be
a valid way for mid-career people to refresh or learn new
skills to help manage their careers.
