"But there is something here that we disagree about.  I believe that it
should be fairly straightforward to perform this experiment"

If you think it is fairly straightforward to perform this kind of experiment,
I can only guess that you have little experience with attempts to evaluate
teaching of this kind. They are *very* difficult to perform for a whole
host of reasons, and there is a large literature that discusses this
difficulty. The fundamental problem is that there are too many variables,
and people are too easily influenced. If you think otherwise, please
cite comparable studies that you think prove your point. Note that the
issues are not statistical here .....
