Maryland does not celebrate Columbus Day, so students are in school. To show the impact of Columbus’s voyage on Indigenous people, this exercise provided an eye-opener for students as well as instructors. It was done with four GED classes that were at various learning levels. Students were randomly selected from each class to participate in the trial and one class served as observers and writers of the exercise. Students were able to show clear critical thinking skills that we rarely use with our other learning materials. The students and instructors truly enjoyed the exercise and it was reported in our newsletter.
