The Ethics of Big Data in Higher Education
By Stephen Downes - Stephen's Web. The Ethics of Big Data in Higher Education
Jeffrey Alan Johnson, International Review of Information Ethics, Jul 31, 2014

- Data mining eschews the hypothetico-deductive process, relying instead on a strictly inductive process in which the model is developed a posteriori from the data itself. More...
Student Data, Privacy, Ideology, and Context-less-ness
By Audrey Watters. I want to pick back up on some of the ideas I started to flesh out yesterday, based on Tressie McMillan Cottom’s recent talk on ideologies and identities in digital domains. Again, not sure where I’m going with this…
Tressie highlighted the ways in which new educational technologies – MOOCs for example – assume a student free of place, free of context. "Free." That’s a deeply ideological assumption, no doubt, one that erases race, class, and gender for starters. I tried to link her arguments to a tweet by Knewton CEO Jose Ferreira, who defending his company from parent-privacy activists, tweeted that Knewton “can help students understand their learning history without knowing their identity.” There, I argued, we see this nod to “identity-less-ness” – a notion that with the right engineering, the right algorithms ed-tech can be personalized to your academic needs without knowing your person.

Hard Questions About Big Data
By Justin Reich and Mitchell L. Stevens. When the teacher and poet Taylor Mali declares, “I can make a C+ feel like a Congressional Medal of Honor and an A- feel like a slap in the face,” he testifies to the powerful ways teachers can use emotions to help students learn and grow. Students -- and their parents -- put a great deal of trust in college educators to use these powers wisely and cautiously. This is why the unfolding debacle of the Facebook emotional contagion experiment should give educators great pause. Read more...
