Writing is already open source. You just have to give attribution. You don't have to rephrase something. That's what quotes are for. The problem with plagiarism isn't really students not citing where a statistic comes from (which is a problem. I always tell students that no one ever got in trouble for citing too much...) but is when they take whole papers or paragraphs from someone else and present it as their own.
