The Center for Online Judaic Studies, which is being run out of NYU, has posted its first educational resource guides (on Jewish-American history, prepared my good friend David Koffman, and women in Jewish History, prepared by Shira Kohn).
The guides include some great images, as well as an outlines with info and classroom activities for teachers to use. The cultural history items look particularly interesting and may be the most intriguing as far as teaching high school kids. See for example Shira’s module on Betty Boop and David’s on American Matzos.
