"السلام عليكم"

First of All, I would like to welcome all the students in the new group of course 452. It is a pleasure having you all and I would say that my two lectures I gave yesterday were great. I enjoyed my time with you. I hope you all the luck in this course. 

For my part of the course, I already gave my two lectures, the bone and joint infections and the interpretation of bone and joint radiograhy. In order to assess the benefit from the lecture, I'm going to email you a few MCQs about the infection part. I believe that this interactive exercise is critical for students engagement and learning. Research shows that even simple retrieval questions have significant pedagogical value. 

Good luck!
