Your best mind is the one that keeps asking questions until you get the quality of information you want.
Asking questions and solving problems is like an aerobic workout for the brain.

In the same way that physical activity increases physical ability, increased brain activity increases the brain's ability to learn.
So if you want to help develop a learning brain, it is important that your learning include inquiry.
Most school situations seek to simply fill a student's head with a litany of facts. Their usual tactic to accomplish this is a lecture or reading assignment, followed by some type of assessment in the form of questions on a worksheet or test. Unfortunately, this doesn't allow for much opportunity to question or solve.
A better approach would be to give the students the questions first. Give them the opportunity to seek out the answers on their own. By working to find the answers and to solve problems, the brain is more fully activated. More than just learning the information itself, they also have a better chance to increase their brain power as they do so.
What's great is that kids really like this approach. They like to be in the driver's seat. Most students would prefer to go on an information-seeking adventure than to have the information spoon-fed to them. Why? Dynamic learning feels good. In this way, healthy learning patterns are created and students can be better prepared to be information-finders and problem solvers as adults.
Give the brains a chance to grow!
