My super cool cousin uses this program in his classroom. Its much more engaging than power point and it is easy to use, you don't need the advanced version so the free version is definitely useful in a classroom setting.
I thought this site was especially fitting for our CI 335 class because it helps teachers incorporate technology into their curriculum and classrooms. It has links to an online textbook, primary source documents, videos, and much more.
The site includes an up-to-date U.S. history textbook; annotated primary sources on United States, Mexican American, and Native American history, and slavery; and succinct essays on the history of ethnicity and immigration, film, private life, and science and technology among many things.
This site is devoted to primary sources and ideas for teachers on how to teach a specific era of history. This site includes links to movies, powerpoint slides, primary source documents, lesson plans, and handouts for teachers.
