Technology is a huge part of the new curriculum in schools. Many school are using Smartboards, and computers, and some even have iPads for the students in the classrooms! At first, I am sure there was hesitation about the students using the equipment for the right reasons and the possibility of a student looking up inappropriate material and causing an issue in the classroom. To me, this can be handled by simply knowing your students. You, as their classroom teacher should know them pretty well and know if they are mature enough  to handle certain modes of technology. By directing them and monitoring the activity on the Internet, it can be used in a safe and educational way.
The same idea goes for video games. There are some games that are inappropriate for young students. The instructor has to be an active part in picking the games and websites.
