What Darren saw happen between a blog comment conversation between his Pre-Calculus student and someone from Australia was amazing, even more so considering the timing of this conversation.
I looked it up, the commenter was from Australia not Hong Kong.
The “research” wasn’t deep, but it was after the course had finished. The last class was Jan 20, 2006 and the comments back and forth happened over the following three weeks when the student was no longer taking any classes with me.
