The document discusses effective feedback and its impact on student motivation and achievement. Effective feedback focuses on the learning goals and success criteria, reduces the gap between current and desired performance, and provides direction for next steps. The most effective types of feedback are self-regulatory and process feedback, which support self-assessment and learning strategies. Less effective types include personal praise and right/wrong feedback, which do not relate to the learning goals. Providing clear, focused feedback and giving students time to reflect and improve are important for maximizing its benefits.
