I've had the opportunity to work with three different classes this year, and two of the three have had a highly disproportionate share of students with major behavioural issues and other challenges for their grade level (only two classes per grade, and the students are distributed alphabetically, so it's pretty random.) I guess this just happens sometimes, and in the Infant cycle, the teacher loops with the group for three years (in this case, that means 3, 4, and 5 years old.) Anyway, being in their classrooms, I see how hard the teachers work, and how absolutely exhausting and draining it is to be dealing with it all day. (The third group is a good one-- normal kids, with normal behaviour issues, but nothing like the multiple problems in the other two.) Well, these two teachers don't complain a lot, but when they do talk about some of the challenges they are facing, they don't get a whole lot of support, and behind the scenes there seems to be an attitude of, "Yes, it's a bad class, but the teacher(s) are at fault, too-- if it were my class, I would handle it much better." While I agree that a teacher can do a lot to set the tone for a group, and that different management styles and techniques can have different effects, from what I've seen, I frankly don't think that any of these other teachers would have gotten drastically different results. So I'm left a bit disconcerted, wondering if this is common-- that not only does it sometimes happen that one teacher ends up with all/most of the "problems", but that if it does happen to you, you can probably expect little in the way of sympathy and a lot in the way of blame. Again, I'm sure that there are cases where a teacher's management style really does have a negative influence, but is this the general assumption?
