It was the last phase of the project in which just some students remained while many others left.

Students evaluation was the hardest part. In iranian system of education the teacher has only 25 percent to put his own assessment for the students mark and most of the time that is often carefully examined by the supervisors. Now I faced the problem, what should I have done with the perfect job that my students have done. They should have recieved the full score in their couse but I was not freely allowed to do that. Hopefully most of the students were intrinsicallly motivated and did not expect such marks. Most of them liked the idea of open house and enjoying the present

ation of their project to so many others.
