Grammarly is a free website to help teachers to detect any possible plagiarism in students' papers.

Audio Archives:
Audacity is free software that students can use to record interviews

This year, the Ted Talks prize went to Dave Isay of StoryCorps. He used the funds to develop a StoryCorps app. The app helps you pick questions, time your interview (Story Corps is traditionally a forty minute interview, later cut down) and upload it to the Library of Congress

Software students can use to create graphic logs (not sure it would work for this project, as it seems considerably more simple that creating a walking tour!)

And just for fun:
Students can create their own movies using legos to tell a story…

Website samples
The Liberty Square Rising Project which I used as an example of this kind of assignment – this was done by FIU students who worked in groups to develop stories/videos/narratives on the history, current voices, media coverage, housing history, and next steps for Liberty Square. Collectively, they created the website. These students worked in partnership with the Liberty Square Council to meet and gain access to residents and develop trust with locals before filming.
