Lately, I have been more and more exploring Google Drive and its tools. I am especially fond of how easy it is to create forms to assess a student's work. Since the interface is user-friendly and it is easy to share those forms, I had my students create their own forms for collecting data. As I mentioned previously the 'showcasing effect' and the ability for the students to poll their friends is a great enticing technique to have them put effort into creating a great PBL. I have also posted on my blog Babeltek a lesson plan detailing how to conduct such a project in a classroom.
