We continue to hear criticism of MOOCs for their low completion rates. I don't believe that is the best measure of a Massive Open Online Course's success. Many learners in a MOOC are only interested in certain portions of the content and enter the course with no intention of completing all the aspects of the course.

screenshot of the hatnote visualization of Wikipedia edits
There is a wonderful STEAMy mashup application online that lets you listen to the edits being made right now on Wikipedia. How? It assigns sounds to the edits being made. If someone makes an addition, it plays a bell. It someone makes a subtraction from an entry, you'll hear a string plucked. The pitch changes according to the size of the edit - the larger the edit, the deeper the note.

It seems that I am most likely to hear the word "transparency" used these days in the context of politics, science, engineering and business. The term implies openness, communication, and accountability. Being transparent means operating in such a way that it is easy for others to see what actions are performed. I don't hear it much in terms of education.

In this information age steeped in computers, the engine humming under the surface of this website and much of the technology we use is full of mathematics and computer science. That means it uses algorithms. I was reading a story about how Facebook again (probably constantly) tweaked its algorithms for what we see in our news feed. What is all this about and where did it come from?
* If you want to know how to compute the RSA algorithm shown partially at the top of this post, including how to select values for d, e, n, p, q, and ? (phi), you can watch this video. It also will help insomniacs.

I saw a tweet from @chronicle for an article titled "Understanding the Origins of Ed-Tech Snake Oil" and that "snake oil" caught my attention. This has to be an opinion piece and someone is not happy.
