Assessment for learning involves using formative assessment to check student understanding and provide feedback to improve learning. It focuses on giving constructive feedback that informs further learning rather than comparing students or grading. Research shows feedback on errors and getting students to correct mistakes significantly improves performance. Feedback also positively influences motivation and self-esteem. For feedback to be effective, students must use it to further their own learning. The quality of relationships between teachers and students impacts how students engage with feedback.
