This week, World Vision released a video showing what it might be like to have your classroom torn apart by war. In about two minutes, Life As a Classroom shows the destruction of once-friendly schoolroom over Syria's five-year conflict. As the video opens we see the teacher energetically teaching from the front. The walls are covered with colourful posters and a map of the world. All is peaceful. All is as it should be. Suddenly we hear the chanting of political protests in the street outside. Teacher and students move to the windows to look out. That's when things begin to change.
