Professional Development Readings

Just got off the phone with David Jahner, NADSFL President, and he was musing about this question.

What sort of language supervisory materials do you often use with teachers? Por moi, I use the following: "ACTFL Performance Guidelines," "NADSFL Characteristics of Effective Foreign Language Teaching," "Standards for Foreign Language Learning in the 21st Century," "IN-VISION materials, "Languages and Children: Making the Match," "Teacher's Handbook: Contextualized Language Instruction," "Nebraska Framework for FL Learning," "FL Articulation," and "Understanding by Design."

I'd be interested in learning what others are using....
