"Do not train a child to learn by force or harshness; but direct them to it by what amuses their minds, so that you may be better able to discover with accuracy the peculiar bent of the genius." - Plato


I feel that this means that if you want a child to learn you cannot force knowledge upon them in a harsh way. If you want them to learn you need to find fun and creative ways to teach them and help them retain the knowledge you give them. Through helping them learn in fun ways will help you to discover new things about your students.
