Tsueng Kwan O Government Secondary School and a group from Lok Sin Tong Leung Kau Kui Primary School won top honours in the 2nd Inter-School Project-Based Video Competition. The entrants were judged on a number of criteria, including the central topic, method of expression, creativity and production skills. The winning entry in the secondary school category was a video about a young girl who is obsessed with losing weight, while the triumphant primary team focused on eye care. A number of prizes were awarded to winning teams, with the top award being a computer system. The annual competition aims to help students learn more about society through the production of an eight-minute video. 'The purpose is to use digital technology to help students spark their creativity, broaden their views and improve their critical thinking skills,' said Jacqueline Cheng, Hong Kong Education City chief executive. The theme of this year's competition was health. Entrants for the primary school category had to create a video based on the theme 'health is priceless'. The topic for the secondary category was 'weight loss costs'. This year's competition attracted entries from 200 secondary school teams and 250 primary school teams - nearly three times the number of submissions from last year. The tech-savvy students said they gained a lot from the experience. Not only did they realise how much hard work is required to produce a video, they also gained an insight into health issues. 'We decided on the script after doing a lot of research. It was difficult. Every day, I stayed at school until six or seven o'clock to draw up the script and get the angles right,' said Yim Man-sze of Lok Sin Tong Leung Kau Kui Primary School. Teammate Mak Ka-sum said that people should 'pay attention to their eyesight and take care of their eyes; don't stare at [computer] screens too closely or for too long'. Nam Nga-chi, from the winning secondary team, said he was enlightened by the experience. Just because the world thinks that skinny is equivalent to beautiful, it doesn't mean we have to succumb to this kind of thinking,' she said. Additional prizes were given to the best live skit and most Web votes. In the primary category, C&MA Chui Chak Lam Memorial School won the best live skit with their performance of the Health Rangers. A video by a second group from Lok Sin Tong Leung Kau Kui Primary School won the Web vote, which was determined by the public in an online poll. In the secondary category, St Paul's Convent School won both the live skit and Web vote categories.
