Absolutely. Typical expectations at this grade level should include managing their own study habits.
But it doesn't strike me as something worth going to the wall over, nor do I think it can definitively be interpreted as insulting. Most teachers have good intentions, and this teacher likely had no way of knowing what her students' study habits were entering the class. She may very well have estimated them based on last year's class (perhaps they needed constant close monitoring).
My point was more that one expends emotional energy to little productive effect on objecting to being told to do something that one is already doing. Sometimes it's most conducive to achieving one's long-term objectives to simply say, "okay," and carry on.
And I doubt that it will last, as, unless she's not planning to monitor the signature (in which case there are no consequences to you and your DD ignoring the homework log), she's just created a boatload of paperwork for herself.
