The younger group use much more technology than the older group of people because it is in some of kids mind they can't live without their phone, tablet, computer, play stations, and etc.
The usage of technology can be one of the effect that children aren't getting better grades. It can be a distraction to them when they are doing homework, or preparing for tests.
Can we teach children proper usage of technology in their life? The internet is all around us in today's society and if you don't have one you might be considered a left out. When kids are younger and they develop a tendency of staying on their technology for as long as they want they can easily become "attached"or addicted. There are no right age to give a children their first technology, no right ways to start out their technology usage (when parents aren't around to monitor).
The ways that can prepare a children to start their contact with technology is by telling them what it does, set time limits (make sure to take away if violate the rules), have open talks with them when need to, don't be the one that set bad example or give to them without thinking.
