Tech companies have outfitted classrooms across the U.S. with devices and technologies that allow for constant surveillance and data gathering. Firms such as Gaggle, Securly and Bark (to name a few) now collect data from tens of thousands of K-12 students. They are not required to disclose how they use that data, or guarantee its safety from hackers. In their new book, Surveillance Education: Navigating the Conspicuous Absence of Privacy in Schools, Nolan Higdon and Allison Butler show how all-encompassing surveillance is now all too real, and everything from basic privacy rights to educational quality is at stake. The tech industry has done a great job of convincing us that their platforms " like social media and email " are "free." But the truth is, they come at a cost: our privacy. These companies make money from our data, and all the content and information we share online is basically unpaid labor. So, when the COVID-19 lockdowns hit, a lot of people just assumed that using Zoom, Canvas and Moodle for online learning was a "free" alternative to in-person classes. In reality, we were giving up even more of our labor and privacy to an industry that ended up making record profits. Your data can be used against you ... or taken out of context, such as sarcasm being used to deny you a job or admission to a school. Data breaches happen all the time, which could lead to identity theft or other personal information becoming public.
