Why do YOU think the children have not made the progress expected with you? You have posted what the observers think, but what do you think? A competitive atmosphere doesn't have to be one child against another. I would definitely say my class are competitive. But they compete to be first to move to a new writing target, or to make the most percentage improvement in a test, or compete just among their group as to who will have the highest score. In marking (when I do the full on proper thing) I circle all good punctuation and they compete to see who can have the most circles. Or who has the most pink highlighting (for openers or vocab or connectives, depending on the focus. No-one minds that little Jonny (level 1 writer) had lots of circles all for full stops and capitals, but Sophie (level 5 writer) has fewer circles but for colons and semi-colons.
