Linda - when you have run some experiments on this amazing victims (oops
kids) could you please share what you learn? I have some small small
influence at my daughter's middle/high school. They're interested, eager
and unschooled. I'm eager, overskilled and suffer the curse of knowledge.
30 yrs of professional coding experience makes me useless in helping them
help kids learn. Please share what you learn.
