One excellent example is immersing students in a foreign culture to teach them a second language. Educators must take advantage of the brain's ability to parallel process. Students must have a personally meaningful challenge. Such challenges stimulate a student's mind to the desired state of alertness. In order for a student to gain insight about a problem, there must be intensive analysis of the different ways to approach it, and about learning in general.
Feedback is best when it comes from reality, rather than from an authority figure.
People learn best when solving realistic problems. The big picture can't be separated from the details. Because every brain is different, educators should allow learners to customize their own environments. Designers of educational tools must be artistic in their creation of brain-friendly environments. Instructors need to realize that the best way to learn is not through lecture, but by participation in realistic environments that let learners try new things safely.
