Homework campaign logo help?

A logo is used to remind people of a place or event, so it has to have some sort of meaning dealing with the message. my advice for you is first create some sort of creative "punchy" message, try and relate to it, another thing is what is the campaign dealing with "teachers" and or "education" so thing of some images that would remind you of teachers, some common images are apples, schools, blackboards, while i was typing an idea came to me you might use or maybe gather your own idea you can combine the image of an apple and the earth and make the earth in the shape of an apple, and a punchy slogan could be something like "teachers make a world of difference"
