The teachers chose to focus on improving written feedback to better support student learning in writing. They gathered initial data that showed their feedback was not focused on lesson objectives or criteria. The teachers then worked to define effective teaching and learning, set clear objectives and criteria for lessons, involve students in constructing criteria, and provide more verbal and example-based feedback. This new approach helped students take ownership of their work, self-assess using criteria, and achieve learning goals with less reliance on written comments alone.
