Forty students at Hodgson Senior Public School on Davisville Ave have staged a demonstration against the refusal of teachers to provide report cards as part of their work-to-rule. It was a lively affair as reported by veteran education reporter Louise Brown of the Toronto Star. And there was an element of intrigue. The surprise walk out by the Grade 7 and 8 students was signaled by a phone ringtone simulating a xylophone. As Brown puts it: “Like members of the French resistance, these politically charged young teens had arranged a code that would signal that it was time to get up and walk out of the north Toronto school to protest teachers’ refusal to type in marks on their final report cards. The student reading Tuesday’s announcements was in on the protest plot, said Grade 7 student Alexis Cole — and suddenly, the announcements ended and there it was…“The iPhone ‘xylophone ringtone!’ ” she said.
