I highly recommend school staff take a look at the splcenter report “The Impact of the Presidential Campaign on Our Nation’s Schools.”
But I also want to remind school staff that the effects of this election season is not limited to classrooms where hate is actively promoted. These effects on schools, classrooms, children, teaching can occur even with well intentioned school staff, if they’re not well informed.
For example, when sharing world news videos about ISIS/Daesh, it’s pedagogically essential to properly frame such news for your young viewers. If teachers fail to contextualize, frame, and inform students, the climate of hate will frame world events as further foundation for hate. Teachers may not mean for it to do so, but inaction and lack of pedagogical proactiveness will let the devil in the door, despite your intentions.
