Where's the research?

Throughout reading this chapter, I noticed that it mentioned that there was little to no research available for writing this essay. After almost everything they mentioned, there would be a caption, like "...has not been studied," or "...is not known." I think there is an underlying message within this discussion. Too many people in our society are too embarressed to discussed the first time they masturbated or noticed pubic hair growing. Adolescents is a very difficult time for both boys and girls and the fact that there is not that much studies on it is pathetic. Society has delivered these "norms" and "perfections" that we all need to live up to and the stress and pressures are almost too heavy to bear sometimes. schools are a perfect place to introduce the changes and urges that accompany puberty.  But should parents just assume that all their children need is what they hear at school? Talks at home or anywhere are also needed. I remeber my parents talking to me about sex and sexual relationships but i recall learning the jists of it all at school.  Maybe psychologist or behaviorist could conduct research at schools to conjure up more information on this topic.  

But maybe there is too little information on adolescents because when does adolenscents begin and end? Everyone will have a different story on where and when they first discovered that they were in puberty.  But within the past decade or so, children are experiencing sex earlier and earlier. Sex in on tv and in the music. Are we supposed to introduce sex to an 8 year old just incase they hear wrong information? Or how about the older kids, when does adolescents end? Right after high school? college? marriage? People are graduating college and getting married than they used to. Too many changes in our culture prevent research and evidence to stay truthful for a long period time. A question I had was how can we as soon to be teachers can sympathetic to changing students or how can we help those changes evolve more smoothly with such little advice?
