Why is it important for instructors to ask learners to orally defend why they answered a question or solved a problem as they did?
In the Nuclear Navy, assurity would be tested by asking the student if they would "Bet a coke/soda on it". Sometimes the student was "sure enough in his answer" to say yes... and the student or instructor would buy a soda and provided it to the winning party. More often than not, the student was wrong... but not always, and at time the instructor would pay out just to test the student.
Sometimes the student wasn't sure enough in his answer, and would go "look it up" either confirming his knowledge, or correcting it.
OF course, the military does lead to "life or death" situations, whereas the civilian world doesn't have such stringent reliance on individual knowlege, and such "betting on a knowledge fact, with payouts" is probably frowned upon by academia".
