I had a great time at NSTA last week. I especially enjoyed meeting Ed Linz (of Team Teaching Science), Mary Bigelow (of Rise and Shine), and Mike Bowen and Tony Bartley (of The Basics of Data Literacy). Thanks, guys!
I also want to point out that Waynesburg University (through the Library of Congress) is running another free online course for working with teachers on using primary sources. I took a fabulous course with them last fall, and definitely recommend it for anyone who works with social studies teachers on using primary sources. Find out more here.
