<p>I wouldn’t fuss about an otherwise curious and energetic 9 year old. Lots of school “homework” these days is busywork and she may just want to get done and on to more interesting things because she has good judgment. But if this topic interests you look up the social psychologist Carol Dweck’s work (she’s currently at Stanford). There is also material on her on the Cal (Berkeley) site Science for the Common Good She has done a number of studies that show the critical importance of parents praising effort-not outcome (eg: how hard someone worked on a subject/test–not on the A). Parents who focus on the grade undermine long-term success and diminish work ethic/integrity.</p>
