I recently jumped into a couple free couple classes thru Coursera.
I don't know much about the organization, but the interface is really easy to use. Registration took about 1.5 secs. The course materials have been readily available. Each class has it's own forum that is easy to use and interact with as well as a platform for meeting holding voice/video chats and organizing 'meet-up's.
I'm taking Energy 101 - it's super easy so far, but interesting and relevant for me. It's through Georgia Tech. The prof is a bit old school but knowledgeable. There are maybe 3-5 video lectures to watch each week. Each only being 10-20mins long. Each lecture has a little pop quiz to take. I'm not sure if there term papers or finals or what-not as the syllabus and course schedule are updated week by week.
That class was easy enough I decided to try another, so two nights ago I viewed the first lecture in Fundamentals of Electrical Engineering being offered through Rice University. This one is much more advanced - the prof is actually teaching to college level intelligence. I've completed one of the problem sets. It's nice as you get immediate feedback.
I have no real reason for taking these classes. Energy policy is tangentially relevant to my work, but more it's just to have a better understanding of our energy needs and options as a voting citizen of this fine country. I'm just a dummy when it comes to EE so am trying to right that wrong.
Anyone else taken any 'free' college level courses?
I'll leave you with this quote from the EE class...Information does not exist without a signal representing it.
You're all signals. I'll sink you all.
