He is absolutely right...It would take me a year to reply as in detail as I would like, but won't be pulling out the soapbox...will just say that the system should reward the multitude of different thinkers and ways to problem solve (because really, we won't be able to prepare kids for what to expect when we don't know what's coming in the next 5 years as Ken stated) ..
It's not about having the answer, but knowing how to find a solution.
It takes all kinds- abstract, random, logical and sequential thinkers.

It's time to buck a system that rewards the student with the best memorisation skills.
