Rough Research Proposal

One of the most difficult tasks student experience is trying to find a good research topic. A topic that is interesting, valid, has accessible information on and something that sparks other ideas. I browsed some topics and, while it was difficult for me to just choose one, I came up with this inquiry question:
Should textbooks and other educational materials be censored for children in schools?

Other questions might include:
What is the effect of social networking on children?
Are children learning bad habits more quickly than in previous generations?
How does this [the above question] affect their education?
How have school curriculums changed with the more frequent use of technology?

My stance will be somewhere in the middle. I think that children shouldn't be completely sheltered from the world, but shouldn't be exposed to things like war and politics that may not be understandable to a nine year old for example. Textbooks shouldn't be censored for high school students because they are getting ready to be independent and go to college in the real world. If they are sheltered from the craziness of the world, then they will not adapt to it easily. Younger children should have an idea of what's going on in the world, too.

I have a younger sister who probably knows more about the real world than I did when I was her age because times are changing. News is easily accessed and is basically everywhere! Technology is a much bigger part of society now and school curriculums are moving more quickly to keep up with the fast-paced world. I think of it in this way: if it is vital to learning and education, then it shouldn't be censored, but if it can be harmful to see/read/listen to then it should be censored.
