Project Progress

I almost done with my final project but I am not sure how far I have to do. My project is teaching a new language so it has a lot of contents and take a lot of time to complete everything. So all I do is selling my idea and showing some dummy pages to show screen design, information design and interaction design. Another thing I tried to develop is using screencasting software for my project.Mostly people use screen cast for teaching softwares, how to use the websites.How can I use screen cast for teaching language? I have finished this piece of work and it's ready to show. Although it isn't perfect but at least I found another way to use this program for education.
