Hi everyone, Does anyone have any tips for when students are defiant? In particular, when giving corrections to students while moving around the school who that are not in your class. Instructions regarding safety, such as to climb down from standing on top of the hand railings, are often met with sullen silence or the word 'no'. I have tried instructing, encouraging, explaining the safety risk, a short positive conversation before the correction, alternative choices, distraction attempts... It is too minor to take further, but too much for me to just walk past. Any advice?
