This twelfth grade annotated inquiry leads students through an investigation of a hotly debated issue in the United States: the gender wage gap. The compelling question “What should we do about the gender wage gap?” asks students to grapple not only with how to quantify and interpret the gap but also to consider ways of addressing the problem. Throughout the inquiry, students consider the degree to which economic inequality reflects social, political, or economic injustices or whether it simply reflects individual choices and the role the government should play in decreasing income inequality.
