This document discusses the importance of maintaining a positive ratio of interactions with students, where teachers provide 4 positive interactions for every 1 corrective interaction. It notes research finding this 4:1 ratio to be most effective for improving classroom culture. It explains that any interaction, even a seemingly positive one, counts as corrective if the student is misbehaving. The key is attending more to positive behaviors. Left unchecked, typical classrooms have observed ratios of 5-15 negative interactions for every positive one, highlighting the need for teachers to actively work on providing more positive feedback and interactions.
