I found that the usage of the presence of a "Discipline Master" to correct and discipline children generally helps. This is especially so for rowdy and noisier children as discipline was much better as compared to previous sessions. Many kids were attentive and focused on their studies during the tutoring session. However, I learnt that the usage of a "Discipline Master" should not be used excessively. This is because it may place too much reliance on that particular mentor to discipline, thus the children may overlook and bully other mentors instead. Hence, other mentors should also learn and know how to discipline the children, if needed.
Moreover, I also learnt that it is important to be firm in principle, yet gentle in our tone. This is to ensure that children will not be disciplined based on shouting and fear, but instead understand why they had to be disciplined. This can be done by speaking slowly and firmly, and ask them questions instead of shouting at them in front of other children. It is also important for mentors to squat down to the children's height level and talk to them, instead of talking down to them. This will create a more personal touch and relationship, thus the mentor will be not be seen as a highly authoritative figure, such as a parent or teacher. However, it is important not to let the kids overwrite the authority of the mentors, but still be firm with them.
In conclusion, I hope that these various ways of disciplining children will be effective for me to use, when facing naughty or noisy kids.
