I have attended (in-person precovid) a couple of educator professional dev. workshops at Georgetown U. in Washington, DC for educators. I'm not sure it they have or will continue to provide virtual workshops/seminars. However, if you sign up they always send info about their program and various events. They are the only academic center tin the US that focuses on Arab studies esp. contemporary Arab studies. Go to the section on their webpage and click on resources> K-14 education outreach. I also know the director, Dr. Susan Douglass, who was my elementary history teacher many years ago :) Check them out!
