How do I teach about inequity in computing resources?
This seems to me to be the sort of topic that is best covered with an assignment such as
Write a paper, citing resources, on the topic of XYZ.
There are a number of other things that can be addressed this way. One advantage of such an assignment is that students have to write using natural language, which often gets too little attention in technical fields.
Another advantage is that you can have the work done in pairs or teams.
Another advantage is that you can follow up with class discussion, seeking consensus on the problem.
You can, of course, provide them with an initial set of resources so that they are forced to look beyond Wikipedia and other easily found resources.
You can also ask for critique of the resources that they find, not just reporting. You can even have a debate. Lots of possibilities since the topic is both serious and open ended.
