Now one of my teaching assistants has discovered why. Given
two numbers, these students are unable to identify which is
smaller. No, I am not kidding. Yes, this involves numbers
between 0 and 1. My TA spend half an hour trying to teach
them how to tell which is the smaller of two numbers, without
great success.

I have seen the same problem in other contexts, specifically
teaching the Rescorla-Wagner model and identifying sensitivity
using Weber's law.
These students can't pick out the smaller fraction if asked to
choose among 0.20, 0.04, and 0.008. The questions are
straight-forward. Which CS will show quicker conditioning?
Which sense is more sensitive to noticing change.
