Educational Leadership:Looking at Student Work:The Secret of Effective Feedback - Dylan William | E-Learning-Inclusivo (Mashup) | Scoop.it
Most of the time, however, the student work we're looking at is not important in and of itself, but rather for what it can tell us about students—what they can do now, what they might be able to do in the future, or what they need to do next. Looking at student work is essentially an assessment process. We give our students tasks, and from their responses we draw conclusions about the students and their learning needs.
When we realize that most of the time the focus of feedback should be on changing the student rather than changing the work, we can give much more purposeful feedback. If our feedback doesn't change the student in some way, it has probably been a waste of time.
