This is what happened when the MOE only allow the principal to cane or punish the students. During my schools days, no matter how naughty we were outside school, we still respect our teachers. My teachers used to cane us on the palm of the hands in primary school days with a wooden ruler. In secondary school days either kena pat hard on the back or knock on the head with a book, sometimes even kena pull by the ears. Nevertheless, we all grew up to become responsible & upright person. Ever since LHL got promoted quickly to BG, all young scholar teachers also became principals at a very young age. No experience in managing the school but very good in giving orders to the elderly teachers who put their heart in teaching the students. So sad education system in Singapore now.
