Does this strike anyone else as internally inconsistent?
Hmmm.... I see a certain resistance to a scientific, experiment based
approach to physics education testing.
That's not what I saw.
... one can always attack
the validity of the objective test instruments advocated.
But you have to at least challenge the test instruments used.
For example.
How do you validate auto mechanic training/education?
By having a subject fix or replace an auto transmission,
an engine, or a a wish bone suspension, and having the
vehicle perform satisfactorily, thereafter.
But perhaps that mechanic was trained on one brand of car,
and subsequently tested on the same brand of car. You can't
spend three weeks testing him/her on multiple brands with multiple problems.
It this case, I would be happy to use a verbal test as a supplement
to discover if the mechanic _understood_ the concepts involved in
changing a transmission and the differences between brands.
