The Sunday Morning Post on October 17 dealt with two issues in secondary school education, in the article on the Native-speaking English Teacher (NET) scheme (Postmagazine) and the very disturbing feature on secondary school discipline in Hong Kong (Agenda).
Even in Australia 20 years ago, secondary school discipline was not as dire as that which you described. This brings me to my point, that popular education in Hong Kong is antiquated and Victorian. It does not reflect the sweeping changes which have moved through the UK, the US, Australia and New Zealand since the Victorian period.
