I don't normally have my students line up outside the door, and in past years I generally allow my students to enter and continue conversations as long as they are getting work done. However this hasn't always worked out. Students frequently don't have their materials out and prepared. This year when they enter I would like to have them enter silently and get straight to work. A problem might occur though simply because they would all be entering at different times. I generally stand in the doorway so I can keep an eye out, but it might just be easier to have them wait outside the doorway and get them all started at the same time. The only thing is that I teach 8th graders and that feels very elementary school to me. Some of our teachers do this, and some do not. What do you think?
