The students in Kristen Link’s high school German classes in Illinois learn a lot more than a new language. With the help of Echoes and Reflections, they also learn about one of the darkest chapters in German history. Link has taught the Holocaust as part of her German classes for over 15 years, but said she has felt for a while that something was missing from her teaching. She thought that there had to be a way to make her teaching on the subject more effective.
