Next year I think that the blog posts and speeches will be a good way to go about the project. On the other hand I also believe that the speech should be in a lower pressure situation so that people will not be so nervous.
I believe that the entire school should have the 20 time project for at least one year or as an option as a separate class. The reason that I say this is because I think that 20 time teaches students that it is not all about being successful and that sometimes failure is just as key in learning. I also think that 20 time developed my public speaking skills and that it would be good for everybody to have their skills upgraded.
My advice to any future kids that try 20 time is this, make sure you like what you are doing before you commit, and collect pictures so you aren't scrambling at the end.
Thank you for keeping up with my 20 time project!
