Earlier quoted context omitted.
> There's an endless search for an effortless way to learn math. Nonsense. There is a search for more effective ways to teach math. And there most definitely are differences in effectiveness, so no reason to believe that any given way is optimal. > Just like there is no way to get strong without hard work. There are, however, lots of ways to spend a lot of hard work for little gain.
If we were finding better way to teach then kids scores would improve, but they aren't improving.
- The scores don't effectively measure learning.
- The need to prepare students for tests undermines the ability to try different teaching approaches.
- Scores don't change overall but the distribution of scores change.
- The distribution of scores don't change but the demographics of the students in a given part of the distribution change.
- There are confounding factors such as budget or classroom size.
