The document discusses the importance of providing effective feedback to students and some of the challenges teachers face. It notes that while feedback can significantly impact learning, too much or ineffective feedback may have unintended negative consequences. The author argues that teachers should be clear on the specific reasons or purposes for giving feedback, such as providing clarity, motivating increased effort, or raising student aspirations. With a clear understanding of the purpose, teachers can give feedback in a way that is more likely to produce the desired results in students' learning and achievement.
