I've been invited to give feedback to all Parsons students, regarding your thesis projects.
This is a very interesting design challenge that, in our ever-increasing multicultural communities, I'm sure many people can relate to! You've articulated a pretty clear problem statement and your proposed solution offers a package of tools for people to use at their leisure. I'd like a little more detail about the CONTENT of the language-learning guide(s), however:
Are you partnering with an existing language methodology (like Rosetta Stone)? Are you finding a way to enhance language-instruction schools around the world that might benefit by partnering with this project and sharing (Open Source style) their teaching methodologies? Perhaps there could be a companion website that members could access and download these tools and, even better, share stories of the struggles and triumphs of intercultural marriage...how their learning evolves (or not)...and how their culture can sustain (or not)?
There's lots of room for here for rich storytelling! Great idea. Best of luck, J.
