 One of the things that I really like about hypothesis is we've touched on this a little is the idea that when we're dealing with one of these challenging texts that it gives students a way to participate in a way that feels comfortable. An example in my class is we talk about an article called why the whiteness of archaeology is a problem because my discipline is historically very colonial and very western and its scientific perspectives and way of thinking. And even ideas like aliens built the Egyptian pyramids have an undertone of racism as they imply that indigenous peoples around the world were unable to create these great accomplishments on their own. And that's a kind of a big idea for students to tackle and we are dealing with it throughout the entire semester. But when they read the article on whiteness and its role in archaeology. It gives students a way to have a much better conversation than we could have just by talking in the classroom because they, they want to choose their words very carefully in dealing with the topic is as challenging as discussing race and racism. So I really, really value the way that they prepare for difficult discussions by annotating in advance.
