Students examine Ellis Lewin’s testimony in the Information Quest about his life before, during and after the Holocaust.

Tenth grade world history teacher Joseph Christensen, from Northwest Career and Technical Academy in Las Vegas, is an avid user of IWitness after discovering it a year ago.Last year he attended a professional development program about teaching Holocaust in the classroom. One of the presenters showed the IWitness website and database and explained how he used it in his classroom. After searching through the website, Christensen decided to also give it a try.
