relationships and reshape the arts and sciences notwithstanding, digital media are amplifiers of the best and the worst, the sublime and the mundane, the significant and the most trivial elements of human behaviour, knowledge, and interaction. How could it be any other way? It is all here online-statements, images, sounds; acts of hatred and love, war and peace, bullying and courtship, truth and lies, violence and care, and oppression and liberation-and in every possible third or fourth space, in ever proliferating redundancy, cut through with noise and clutter.How we can enlist and harness these media to learn to live together in diversity, mutual respect, and difference-addressing complex social, economic, and environmental problems while building convivial and welcoming, just and life-sustaining communities and societies-is the key educational problem facing this generation of young people and their teachers. This is an ethical vision and an ethical challenge.Many school systems are in shock and denial over this turn of events, especially given the historic use of print textbooks as a practical and effective means for defining and controlling what might count as official knowledge for children and youth. Schools have responded with a patchwork of rules governing what kids can and cannot do in their online exchanges and communications. These emerge in a reactionary and agglomerative way, often in response to incidents of abusive, illegal, or symbolically violent online acts, or to events whose origins are attributed to online actions-from suicides to gun violence to pedophilia. Schools work from a mix of regional and district-level policies that include constraints on hardware access, proprietary lockout and surveillance systems, privacy and intellectual property regulations, and school-level codes and class rules on everything from texting and screen time to plagiarism and copying from internet sources. These sit alongside home-based restrictions (or freedoms) on time, access, and use in those families that can afford mobile and online devices. This is complicated by increasing law enforcement efforts to prevent the online recruitment, exploitation, and indoctrination of youth by terrorist groups, financial scammers, and criminal organisations. In this thicket of overlapping systems of surveillance, unmediated exchange by youth and children would appear to be the exception rather than the rule (Boyd, 2015). Taken together, the digital strategies of large public education systems in North America, the Asia Pacific, and Europe appear to be at best post hoc and piecemeal-motivated by genuine concern and real problems, but typically lacking stated ethical foundations and working within prevailing neoliberal policy frameworks (the latter of which have eschewed engagement with educational philosophy and ethics more generally). This underlines what has become a significant (meta) ethical dilemma in itself-that the policy push for teaching through and about educational technology presents itself as ethically and poli...
