GenderMag enables your students to identify features in the software they're creating that have unconscious biases tied with gender. (If they can't identify such features, they can't fix them.)
GenderMag gives a concrete way to teach each of these HCI methods.
GenderMag gives a concrete way to evaluate software's user interface, tying well to a class's quality control and/or user-centered design topics.
A GenderMag cognitive walkthrough starts with a scenario/use-case. If you require students to follow the method to structure demo'ing their software, their demo is more likely to tell a reasonable, believable story. Their presentation can start with a GenderMag scenario and a demographically-customized GenderMag persona, and then walk that persona through a sequence of actions the persona is supposed to take in their software demo. (Note: in order for that demo to be believable, it will really help if they first perform a GenderMag evaluation with that persona to see if they can believe that persona would take those actions.)
