Gardner Howard
Professor of Cognition and Education at Harvard Graduate School of Education at Harvard University He tell about "The Theory of Multiple Intelligences"
He explains through an example this theory that a child who learns to multiply easily is not necessarily generally more intelligent than a child who has more difficulty on this task. The child who takes more time to master simple multiplication
1) May best learn to multiply through a different approach,
2) May excel in a field outside of mathematics, or
3) May even be looking at and understanding the multiplication process at fundamentally
deeper level, or perhaps as an entirely different process.
Such a fundamentally understanding can result in what look like slowness and can hide a mathematical intelligence potentially higher than that of child who quickly memorizes the multiplication table despite a less detailed understanding of the process of multiplication.
