Dear Kačka,
thank you for your thought-through comment :) Sure, use whatever from my sheet in yours. I am glad that you found something new and interesting :)
To answer your first question – what I meant was that there is an absence of correction of the T. I just forgot to write it into my observation sheet, sorry. I will correct it. And yes, in my notes there is: " The T can just point at someone and nod to let them know they are right." So the told correction of the T is not there, but the T points at someone and lets them know that they said it right. I hope it makes sense now :)
To answer your second question – I see it as a con for Ss who are not focused all the time. They can get lost in the lesson and do not know what the T is talking about (or doing) and would be really hard for them to get on track again.
