Facebook has pledged more than £1 million to help turn British schoolchildren into "digital safety ambassadors." The scheme, created by Childnet International and The Diana Award, will teach students about social media, cyberbullying and the hazards of the wider internet. They will then act as a support group for their friends and fellow pupils, fielding questions and leading online safety initiatives in the classroom. Facebook says its investment will allow every UK secondary school to have its own digital safety ambassador, should they be interested in the project. In total, that could be an extra 4,500 pupils sharing good advice with their peers.
