A STIMULATING arts programme for students hangs in the balance, depending on whether the Government agrees to sponsor it. Zuni Icosahedron, an experimental arts group, has drawn up an extensive programme, including performance workshops and arts demonstrations and discussions, for its ''1994 School Programme in Arts Education''. The group has applied to the Council for the Performing Arts for over a million dollars to fund the programme, the first such funding Zuni has asked for. Its representatives will meet the council on Friday to present Zuni's arts education programme proposal. But Zuni is not very hopeful, after its recent disappointment when the Recreation and Culture Branch turned down an application for $2.8 million to fund a performance at the first International Arts Festival in Brussels. ''This time, the funding is extremely important to our school programme,'' said Zuni's producer Mr Mathias Woo Yan-wai. ''If our request is rejected, the future of our arts education programme will be affected. We won't have money to employ full-time staff to work with teachers and students.'' Over the past five years, Zuni has sent artists and educationists to secondary schools and tertiary institutes to hold workshops that introduce performing and visual arts concepts to the younger generation. But the workers are volunteers, since Zuni cannot afford to pay them salaries. For this reason, Zuni finds it difficult to launch a long-term programme with helpers who can have a full-time commitment to it, Mr Woo said. Should Zuni get the financial aid, the group will launch a three-year arts education programme. The first stage would involve planning and co-ordination. School visits and interviews will be arranged to link up schools and strengthen co-operation. During the year, there would by 25 performances, each lasting 90 minutes, for an audience of 150 to 400 students. The performances would include video shows, demonstrations and discussions. There will also be 60 two-hour education workshops catering for 20 persons chosen from the demonstration performances. In its proposal, Zuni said the workshops would begin with the existing school curriculum in performing and visual arts education, if any, and develop to include participatory creative experimentation with the students. Two full-time artists and several local and overseas guest artists would be involved in the workshops. Zuni said students would be exposed to new ways of creative thinking, comprehension, communication and expression, while taking part in hands-on experiences in various creative processes. The group pointed out that ''these creative processes are determinant factors in the healthy and overall maturity and growth of Hong Kong's next generation of citizens''.
