On the other hand, short video clips can be helpful to help teachers illustrate a point or present a point in a different manner. If you're a history teacher, particularly a U.S. Hip Hughes History is a channel that Greg Kulowiec shared on Twitter a couple of weeks ago. Dizzo95 is the first YouTube channel that came to mind when I started to build this list. The U.S. The New York Historical Society has a YouTube channel that at first you might not think has anything of relevance to teachers and students outside of New York, but on further investigation you will find content like this playlist of videos about Frederick Douglass.
