Next, based on my point of view regarding the professional development that affected classroom management and discipline, I believe that teachers should be aware with their own responsibilities and continues to find opportunities to develop their skills professionally. The teachers should attend any professional development courses, seminars or events that is provided to ensure that they are updated with the current knowledge of classroom management and discipline. This is because classroom management is a skill that can only be obtained through constant practice and effort to do well in their profession. Lack of knowledge is the reason that the teachers faced failure to control the students’ behaviour and disciplinary issues in classrooms. Moreover, professional development will only have an effect on student learning if it involves the entire school community. Knowledge about teaching and learning only makes sense when considered in the context of a teacher’s own school culture and climate.
