I teach Grade 9 (mostly) and Grade 11 (some). Our school is different in that there are no bells. None. Never. The theory behind it is to force students to manage their time properly and to give them a "window" into the work world. Most professions don't have bells that signify when to start work and when to stop, so the thinking is that we should be teaching our kids to be responsible. For the most part, it works ok with the upper grades. My 11s know to get to class on time and if they can't, how to enter the class respectfully, knowing that I will speak to them after class. My 9s are another story. I, personally, don't think they're mature enough to handle a no-bell system, but there isn't much I can do about that. Last year I stressed the importance of getting to class on time. That when I decided to start class, the door would close and they would have to deal with the consequences. The majority of them got there but, as they have a 10 minute break between periods, they would socialize while waiting for class to start, which is fine. My problem is this: how do I get their attention and let them know that I am starting class if I have 25 students in my room talking, etc., but no bell to get their attention? I suppose that I could tell them to do their socializing in the hall, but that would result in my wrangling them up before class. I find that to be time consuming and it defeats the purpose of no bells. Any ideas?
