From the resource:
Jeopardy is a popular request from students who want an in-class review activity, but Jeopardy has some critical drawbacks. First and foremost, it asserts that there are right and wrong answers which can be condensed into minimal words. Jeopardy, by its very foundation, discourages nuance and critical thinking. It also prioritizes knowledge which is traditionally pale, male, and stale. Second, from a labour stand point, the game demands a tremendous amount of work from the professor or TA who creates it, while those who answer the questions are not compelled to demonstrate significant knowledge. There must be a better way.
The original Cards Against Humanity game is simple. Each round, one player asks a question from a black card, and everyone else answers with their funniest white card. Cards Against Environmental History (CAEH) follows this same format.
