Japanese Foundation Row

I'm starting the Certified Instructors Correspondence Program . Lesson 2, sample one calls for a 5" square single crochet with the Japanese foundation row. I can find no reference to a Japanese foundation row. Does anyone know where I can find this information? I have not received nor do I see where I can download othe Crochet Notebook that I am refered to in other lessons. Am I just missing where I find this? Thank you.
