Let’s teach (learn) for mastery
Posted October 7, 2016on:
This is one of my favorite TED talk by Sal Khan, the founder of Khan Academy.
What a comprehensive explanation of teach/learn for mastery. As my kids were young and not really understand the jargon ‘pre-algebra’, ‘calculus’, ‘algebra’, I gave another example using maths concept they are familiar with, e.g. if they are still confused and cannot master addition of two-digits numbers, sure they will be stuck when proceed to do addition in thousands.
Also his explanation on what a test-score is supposed to mean – identify the gap, and what is missing in current system – closing the gap, and what happen when we move on with the mixing gap, is the key point of all. This is what I would like my kids to know,
“If you got twenty percent wrong on something, it doesn’t mean you have a “C” branded in your DNA somehow, it means you should just keep working on it.”
“You should have grit, you should have perseverance, you should take agency over your learning.”
