I think it is fairly obvious at this stage in high school what is allowed and what is not. If you are doing something on a computer you would not do if there were a teacher standing behind you, it is probably punishable. However, kids are old enough to make their own decisions and some will knowingly break the rules. Suspension seems like a harsh punishment for technology abuse unless the abuse endangers other students or involves drug content. It is going to be a learning process how to discipline students effectively, but I'm sure it will all work out.
