The fact that for 18 years we have dreaded our kids so much with examination centered learning. I see that as the singular big problem for education. Exams, marks, as you were pointing out in the last session that we immediately start asking your kids, how much did you get in XYZ paper? That to my mind prevents learning, real learning. Real learning happens as Kalwaman says that it happens when you make mistakes. And you figure out why did you make that mistake? If you figure out why did you make that mistake that plugs a hole in your understanding.
