This is a bad example of design. This is the door to our classroom. I am very confused by the fact that it does not have a handle. One can leave through the door, but is unable to enter back through it. This means that you must walk some ways back to the original door. I understand that this must have been perhaps created for security reasons, but seeing as the doors can be set to lock automatically, I do not see why this convenient aspect was taken out of design that everyone is so used to.
There were a number of times when I was in this classroom, and had someone ask me to let them back in after they had left through that door. I could see why they asked me to open the door for them when they knocked (a convenience factor) but it was distracting for me and the other class when they knocked.
