With kids, the issue is balance. They do need to know technology, because they start young. At my kids' school in kindergarten, kids have computer lab time with learning games. By 2nd grade, they have them doing Power Point presentations. They also have 2 mobile labs with ipad minis the kids do video projects on, too. By fifth grade, the standardized tests involve typing on the computer--with time limits--so they have to be able to type quickly and well to get good scores.So they need exposure outside school to keep up, imo.
But they also need time to be creative with their hands, engaging their brains and eyes in non-electronic screens, and exercise. My kids have time limits for computers after school, and before they can get on the internet on our desktop they have to do a qwerty typing lesson. Before they get on the G pads we got with our phones, they have to do a math lesson. This way they're getting a small dose of learning in as well as having fun (and I don't have to sit there and hold up flash cards, lol).
