Love the notion of "Dark Social" as a web traffic driver. So true!

What a fantastic post by +Alexis C. Madrigal about "Dark Social." This certainly matches my experience. And another dimension - even things that may appear as links from Facebook and Twitter may have first emerged from email and other "dark social" networks.  I'm sure I'm not the only one who gets a great link from a friend via email and then shares it out over Twitter, G+, or Facebook.  

And all these things might overlap.  For example, I saw links to this piece go by on twitter, but there was never enough context for me to follow the link. But when someone sent it to me in email, with a bit more context, I followed the link, read the story, and reshared it here (and will do the same on Twitter.)*

Περί εκπαιδευτικού μοντέλου και βαθμολόγησης...
I find myself rather fascinated by this article.

If you really believe that the function of grading is solely to give a score to students, the methods that are proposed here make sense. Whether you have grading done by an algorithm or by an outside service that doesn't know the student, why the heck not outsource it? But if the function of grading is to assist in the teaching process, outsourcing grading misses the point.

One teacher I know, who has been teaching writing at a top prep school for over 40 years, told me recently that he's often up till 1 am grading papers. I sent him this article to get his reaction. He wrote:

"Responding to student papers is a teaching activity, not contest-judge work, and so fairness or unfairness isn't even an issue."

He is up till all hours because marking papers is part of his teaching. He's not scoring a test or an essay for purposes of giving a grade.

It strikes me that the whole idea of computerized or outsourced grading is based on a failure to understand what education is really about.

A better direction might well be the one suggested by teachers who have adopted Khan Academy lectures, effectively outsourcing the lecturing so they can spend more time one-on-one with students.

What has the world come to...

"Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and not clothed. This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children. This is not a way of life at all in any true sense. Under the cloud of threatening war, it is humanity hanging from a cross of iron."

Dwight D. Eisenhower (president,ww2 general)

Can you imagine a president or a general say something like that in this day and age? (thanks to roger waters who reminded us of the quote)
