Dear Principal
I am a High School student who play a role in a student movement and we are developing some projects for improving school. Nowadays, technology has increased rapidly but the schools hasn't been using technology in its programs. So we want to show several projects to link school with technologies. In this way, programming is a subject we should learn in this school, so we propose you should teach this subject here.
Sincerely,
Michael Wood.
