Lau Sai-chong doesn't just teach his students about technology, he teaches them to share it with the wider community. The winner of a Chief Executive's Award for Teaching Excellence also inspired his charges to organise a mass march of robots to win a place in the Guinness World Records. Mr Lau won the teaching award for what was termed his 'interactive, project-based approach to motivate students and spread technology to the community'. 'I design two to three projects for students in each form to boost their learning interest,' said Mr Lau, who teaches at Lingnan Dr Chung Wing Kwong Memorial Secondary School in Lai King. This year, his Form Three students are learning how to make a USB memory stick that can store data. Outside school, Mr Lau's students are encouraged to become 'technology ambassadors' who organise workshops for the elderly, ethnic minorities and primary school students. Since the scheme began in 2004, more than 2,400 ambassadors have been trained, aiding more than 7,000 people in the community. 'Through teaching the workshop participants to make robots or to use different software, students can cultivate their skills of communication and collaboration, problem-solving skills and patience,' Mr Lau, a teacher for 20 years, said. This year, he is teaching his Form Two students to make gliders and the students will pass on their knowledge to 150 families in the community. In 2006, Mr Lau initiated a 'robots relay marathon' in which parents and students linked 255 self-made robots in a one-minute march that was accepted as an entry into the Guinness World Records. Form Two student Lee Hiu-ching enjoys Mr Lau's lessons as they are not straight from textbooks. 'I like making gliders and practising during lunch time,' she said. Classmate Lau Chung-yin said Mr Lau's interactive approach encouraged him to learn about technology. 'I look forward to making a USB stick.' First launched in 2003-04, the award for teaching excellence is open to technology education and pre-primary education teachers. In all, 25 teachers will receive the award this year, while 16 teachers will receive a certificate of merit. The award presentation ceremony will be held today at the Hong Kong Polytechnic University.
