Students are digitally intruding on classes. Interlopers are accessing the codes to classrooms at schools, accessing those classrooms, and misbehaving. I spoke with a friend who teachers in Arizona earlier this evening, and he explained that digital intrusions are happening there too. To prevent them, teachers need tools. We need to actively, aggressively build connections with students, and engender care for the learning community. Over and above this, teachers need tools that will allow them to close the virtual classroom doors to digital intruders.
