So how do we end it? A presentation of course!
My students were told that they would tell us about the successes and failures of their projects in a dynamic, cloud-based presentation to the class. I teach presentation skills using TED videos and we practice using the same rubric all semester (see the lesson plan here). For their final semester exam, they are graded on presentation skills using that same rubric and they are graded on their digital component of the project. The digital component has to to be cloud-based and incorporate elements of 21st Century literacy they've learned so far in class.
