The emergence of big data and analytics in public education is bringing new urgency to the national debate over digital privacy.
Take AltSchool, an education startup that is adapting some of the passive-observation technologies already in use in such fields as consumer technology, professional sports, and retail sales. Those approaches include constantly running video cameras and audio recorders, and the use of motion-tracking and facial- and speech-recognition software.
The idea is that more and better information on students, collected unobtrusively as they go about regular learning activities in the classroom, might help make education more personalized, powerful, and efficient.
But where proponents see potential for innovation, others see big trouble.
It鈥檚 especially problematic that big-data-based experimentation is almost entirely unregulated, said Joel Reidenberg, a school privacy expert and law professor at Fordham and Princeton universities.
鈥淭he extent to which a total surveillance environment affects a child鈥檚 learning, psyche, and personal growth is uncharted territory,鈥� Reidenberg said. 鈥淲e need development of ethical principles for the use of these data, as well as objective review mechanisms.鈥�
That kind of independent, third-party review of ed-tech companies鈥� plans for experimenting with big data and analytics doesn鈥檛 appear likely anytime soon. The conversation is only just beginning, Reidenberg said, because big advances in data science are so new.
In the meantime, parents and citizens should be aware of possible harms, said Elana J. Zeide, a privacy research fellow at New York University鈥檚 Information Law Institute. 鈥淭here is the potential that ubiquitous surveillance might chill intellectual exploration,鈥� she said.
Other worries involve the creation of profiles that could linger beyond their accuracy or utility; making key educational decisions based on algorithms that are too complex for the typical student, parent, or teacher to understand or challenge; and the possibility that pervasive monitoring in schools might normalize the kind of real-world surveillance that has landed the National Security Agency in hot water.
For their part, AltSchool officials stress that there鈥檚 a big gap between what they鈥檙e doing currently and what they may do in the future. Parents are opting into the AltSchool model, and scrutiny and debate are welcome, CEO Max Ventilla said.
鈥淚 agree that there is a psychic cost to monitoring that is quite high, and that needs to be overcome to justify the monitoring in the first place,鈥� Ventilla said. 鈥淏ut if you don鈥檛 allow yourself to even get started, you preclude a lot of [potentially] good uses of these kinds of technologies.鈥�
So far, though, legislators and policymakers have mostly struggled to keep up with the ambitions of the ed-tech sector.
One major example: the actions of online-services-giant Google, the former employer of both Ventilla and AltSchool co-founder and chief technology officer Bharat Mediratta.
Just last month, for example, the Electronic Frontier Foundation filed a complaint with the Federal Trade Commission. It alleges, among other charges, that Google is violating the voluntary Student Privacy Pledge by tracking the millions of students who use its Apps for 91制片厂视频 tool suite when they venture to other Google applications such as Maps and YouTube, then using the information to create behavioral profiles.
That capability is very connected to what Ventilla worked on when he was the company鈥檚 head of personalization just a few year ago.
But it would be a mistake to assume that AltSchool will push privacy boundaries in the same manner as Google, despite the histories of some key employees, said Mediratta, who was a top engineer in charge of the larger company鈥檚 homepage for more than a decade.
鈥淕oogle [has] business reasons that cause it to cozy up to that line in ways that are going to upset some people,鈥� Mediratta said. 鈥淏ut for us to be successful, we have to make sure that people trust us with the data we gather on their children and help them understand that it will pay off in a much higher-quality education for their child.鈥�
