It is a real challenge to teach to understand the real difference with internet content property. I would give examples : As a secondary school teacher, I was confronted with students who took all the Internet information as their own creation, without really understanding the role of property or author. How to set up a learning about the rules when the Internet and their authors have trouble finding their own way around these property rules ? Secondly, all universities face to plagiarism. How can the open concept be introduced and face to plagiarism as a restricted key for a university student ?
