There are many types of feedback. After a correct response, affirmative feedback provides the student with praise. After an incorrect response, corrective feedback provides the correct response or how to get to the correct response. Feedback is effective if it is provided consistently after every error, directed at the task (not personal character), is specific, and given in an appropriate tone of voice. Students benefit from attempting the skill directly after the feedback and also later in the lesson (to determine if they still remember).
As a general rule of thumb, if all students give a quick and correct answer, teachers should provide praise (Well done!). If about 2/3 of the class is correct, or if students are hesitant but give a correct answer, teachers should provide praise and the correct response (Great job! That word is fearful). If at least half the students give an incorrect answer, teachers should provide corrective feedback about either the correct response (That word is fearful) or how to get to the correct response (Remember to split the word into syllables and read each part to yourself first. Then say it out loud).
Effective feedback is one of the strongest tools teachers use during instruction (Hattie, 2009). By providing quality feedback, students can identify what they did well, what they should do differently, and/or how to get better.
