Feedback is how teachers enable students to ‘close the gap’ in order to grow learning and improve their performance. For feedback to be effective, students need to know how to take action . All teachers provide feedback to students, which can either be oral, written, or through demonstration. Feedback can include teacher to student, student to student, or student to teacher.
Feedback is most effective when it focuses on the learning target and task and is given while the task is still relevant. It should be specific as to what the learner has done well and what they need to work on. It allows for mistakes to be viewed as learning opportunities. Limiting feedback does not allow students to grow.
It is the nature, rather than the amount, that is critical when giving students feedback.
