A leading authority on school violence has accused the government of doing little to combat bullying in schools, more than half a year after a series of cases came to light. 'I am very disappointed with the Education and Manpower Bureau,' said Dennis Wong Sing-wing, associate professor of social studies at City University of Hong Kong. 'I have held workshops for more than 20 schools in the previous six months, and most of them told me they had not received any support from the bureau.' He said the few large government forums held on school violence were not enough to curb the problem. Professor Wong said the government had paid no heed to his earlier call to provide 'difficult schools' - which adopt an education-for-all mission and have a large number of students with family problems - with more social workers. 'One social worker has to take care of about 1,000 students in each school. It is fine for schools with high-band students, but problematic for those with a large range of problems.' He also criticised the lack of a crisis management team in the bureau to help individual schools tackle bullying. Shum Ka-lai, a teacher at De La Salle Secondary School in Sheung Shui - which saw 11 of its students charged over savage attacks on a classmate last year - said teachers often did not have time to take care of students' emotional growth as they were bogged down by administrative work. He criticised the government for 'punishing' rather than providing additional support to schools with many needy students.
