He who talks the most learns the most

If you've ever had to teach a lesson, or do a presentation, the person in that room who learned the most was you. In order to talk about the subject, you needed to research it, understand it, make mistakes with it, and learn from those mistakes.

Our goal for our classroom instruction is 50/50. We need teachers to talk only 50% of the time and students to talk the other 50%. When teachers talk the whole time, students don't learn, they are asked to regurgitate teacher knowledge. Often times the difference between an A student and an F student is the F students can only remember things until Thursday, one day shy of the test.

When students do the talking, wondering, and mistakes, they own the learning.
