In addition to her reserch and preparing new math teachers, Jo Boaler runs a Stanford University website called youcubed that has a great deal of information for teachers, parents, and educators. Click Learn More below. I recommend her book too - I loved it and gave it a great rating on Amazon. Her online self-paced class (for parents too!) sounds so interesting.. In Chapter six, she gives some advice on grading where suggests trying a 4 point scale and it will be very easy to implement.
The author is a proud mother and wife, living in Sonoma, Ca. She has 21 years teaching mathematics. She loves technology and how it enhances student learning, engagement, and achievement.
