Mobile classes teach primary school students to be aware and readies them for change at puberty Holding pom-poms and files stuffed with leaflets, students lined up outside a colourful truck after an hour of interactive learning about puberty and sexual abuse. Education officer Vian Lau Sze-lok was visiting Lok Wah Catholic Primary School with her assistant in the mobile classroom. They have been touring schools to teach sex education - a topic many adults find embarrassing. 'We usually spend one to two days in each school, paying about four visits a week,' said Ms Lau. Founded by actress Josephine Siao Fong-fong in 1998, the End Child Sexual Abuse Foundation aims to protect children from sexual abuse and raise public awareness. In 2001, the foundation set up multimedia sex education programmes and launched its mobile classroom services, targeting local Primary Two and Primary Five students. There is also a 'hugline', for victims and their families to call for information and counselling. Through Operation Santa Claus, co-organised by RTHK and the South China Morning Post, the foundation is seeking funding to cover one year of a sexual-abuse prevention programme for Primary Five and Six students. In the one-hour class on the truck, Lok Wah's Primary Five class learnt about the psychological and physical changes that occur during puberty, good and bad touches, and how to deal with sexual abuse. Students occasionally giggled and talked to one another, but most raised their hands eagerly when Ms Lau asked them questions. Students stood up and waved in a para para dance about anti-sexual abuse. The lesson ended with a video question-and-answer session, in which students answered by raising glowing red and yellow pom-poms covered with disco lights. After the lesson, Ms Lau waved goodbye to the children, and took a short rest before the next class. Two years ago, Ms Lau entered the foundation as an education officer after obtaining a psychology degree in New Zealand. She said she was attracted to the foundation's values and mission. Later she went on a three-month training course. 'During the three months, I read books, watched videos and attended seminars from clinical psychologists about child sexual abuse. We co-operated with different organisations such as the Ming Ri Theatre about puppetry. 'Since this is an education programme, we are also trained in teaching skills like presentation tone, teaching speed and classroom management. You simply can't talk to Primary Five students like kids, but must treat them as little adults,' she said. There were different syllabuses for Primary Two and Five students. 'For Primary Five, as they are learning about puberty in class, it is also our focus. For Primary Two, we talk more about knowing their bodies and how to distinguish good touches from bad touches.' After their lessons, students are given 'reinforcement materials', including worksheets. Hong Kong education has long been criticised for its weakness in sex education, but Ms Lau disagrees. 'Actually in schools, students are well-equipped on the knowledge side, but the traditional classroom limits teachers to dig deeper into the issue,' she said. In an interactive and relaxing environment, like the mobile classroom, students might find it easier to learn, she added. Miss Lau said some students in her classes did admit to being sexually abused. 'I usually encourage them and praise their bravery in speaking out. I let them know it's not their fault. And we will follow their cases,' she said.
