This study also illustrates the most frequent negative reinforcement approaches practiced by teachers in dealing with disruptive behaviours in classroom are demonstrating and explaining to the students of the appropriate behaviours to be displayed whenever any of the students misbehaves with a mean score of 4.571 which confirmed the findings of Cameron (1998) and Leung and Lam (2003). This is followed by ordering the students to clean the classroom or asking them to help the teachers (M=3.067) and the approach of looking at the students who display disruptive behaviours with frustration and anger with a mean score of 2.983. These findings demonstrate that the approaches practised by teachers are more likely to be on diplomatic basis (Miller, 2006). Teachers are more tolerant by taking actions which are aligned with human rights and qualities as well as nature of parents (Sheppard, 2009). In addition, this study further renders in which teachers as classroom managers should know when exactly to punish their students to avoid unnecessary or disparaging punishment. Teachers who are good in disciplining their students believe that punishment is suitable for repeated misbehaviour. However, if the students show some improvements in behaviours, the punishment should be discontinued. This finding corresponds with Robertson (1996) and Charles (2005) that posits punishment should be the last option in dealing with students’ disruptive behaviours.
