Kids need people to teach them, and the tablets and computers
should only be used to reinforce that knowledge and to put that knowledge to use.
Learning a subject is not something that comes naturally, although people learn about things in their environment by accident. But, cumulative knowledge cannot be gained from a simple tablet, no matter how sophisticated the software or device. People learn best by imitating and from first hand instruction and from others' experiences.
The biggest obstacle to learning via tablets or computers, is the discipline which will be lacking with those "students". Once they learn to "play" with them, and perhaps even pick up some real knowledge, they will become bored and tired of them, and they'll be right back at square one, where the need for a "teacher" will be most important. A teacher does not have to be someone with a 4 or 6 year degree from an university, and could be anyone with valuable information that can be shared.
