This is the default behavior of the Text widget.  You have two options 
(as I see it) one, put the new text at the top of the Text widget 
textwidget.insert(0, "your new text") or two, use the yview_pickplace 
method to move the view down every time you insert text 
textwidget.yview_pickplace('end')

I wrote a sub-class of the ScrolledText widget to do just this
I gave it a write method - so I could re-direct stdout to it - and also 
called yview_pickplace in that method.
