I read today that the math teacher, Jaime Escalante, died at 79. He became famous when a 1988 movie, Stand and Deliver, depicted the teacher, a Bolivian immigrant, as he transformed students in an inner-city Los Angeles high school into math aces. At one point, the school had more students studying advanced calculus than all but three other state schools in the US.
Amazingly, this week I'd shared with my students this story told by Zig Ziglar.
