So...the biggest problem with technology and children

Problems. Hmmmm... This search did not take me to the place I at first expected. As Dr. Cullen announced the assignment fresh on the heels of the Frontline video which documented a young girl's attempt to gain identity through technology, my initial thoughts were of problems with safety. Safety in a physical sense. While I did find evidence of such danger in my search, I also encountered articles on developmental and social problems caused by excessive and sometimes not so excessive techno usage of young children and adolescents. Some of the information seems to lead me to more questions. Questions which I believe will be asked in evolving forms over many years; in my home and across the globe. How much is too much? What is good use versus bad? How do I protect my children from weirdos who could do physical and/or emotional harm? As a digital immigrant, how do I maintain a level of techno competency to even understand what my children, who will no doubt be natives, are doing with technology?
In certain cases the research is suspect. Researchers also seem to be at odds with each other of findings. There seems to be no shortage of opinions on children and how they use and relate to technology. Many of these opinions are posted as if they are research based, when no such basis is present. I did however, find the information on the following three sites interesting and useful.
The microsoft child safety article gave some great, concrete ways to protect children when on line. Step 1. Decide where your child can and can't go on the Internet. Step 2: Increase your security and privacy. Step 3: Monitor where your kids go online. Step 4: Remind kids not to talk to strangers online.
The Tech News World story offers differing opinions on social and developmental issues regarding children and adolescents and their use of technology.
The CUNY (City University of NY) site is a research paper on children's time spent at home on computing and its correlation to cognitive and other measures of well being.
