The best way to make anything become more valued in a society is to instill this idea in children at a young age. Of course there is a catch-22 since those who weren't taught to value it are the ones that are supposed to teach the children to do so. Probably the best way to do this is to put more value in education in general. Personally, I loved going to school and learning, but I'm pretty sure that there are more K-12 students that dislike going to school and don't have a passion for learning, which is sad. Perhaps it is lack of funding, or the parents aren't active enough, or the teachers don't express the importance of learning and how interesting, fun and exciting it can be... or maybe it is how much we let religion affect things here in the U.S. It's hard to say what the cause is, but if that could be altered then perhaps the education system will change, thus bringing about a society that values science more than we do now.
