Computer technology has become a vital element which takes part in almost every aspect of our lives. In visual art, it acts as media for studio art production, tools for learning instruction, and tools for classroom management. However, the development of computer assisted learning in Hong Kong is still in an initial stage. As an educator of art, it is part of my responsibilities to study on the potential and effectiveness of computer application in the learning and teaching of art. This case study research of a programme of teacher education aims to find out the competency and attitude of prospective art teachers towards computer assisted learning and teaching. Result can pave way for future development of computer application for art teaching and learning in teacher education and in primary schools in Hong Kong. New Technology and Art Education: Computer technologies have enormous potential and advantages in enhancing and expanding the way of teaching and learning art in schools. Pupils can experiment their ideas on the screen without fearing of making mistakes and can easily try out their ideas and visualize their images in mind (Mathieson, 1993). These playful and relaxed working processes are a vital avenue leading to creativity (Greh, 1990). In teaching, on-line computer images provide enormous images through the net with a relatively lower cost (Heise,1996). Manipulating images on the screen allows more flexibility in teaching art appreciation and criticism than using slides for presentation (Greh, 1990). With the use of computer, pupils can 'save' part of the process and teachers are free to involve in the interim of their work (Greh, 1990). Computer application provides alternative ways for learning. For example the extensive use of World Wide Web makes thousands of works from major museums uploaded to the Net and on CD ROM which provides means to ponder, confer, and analyze everything from the most obscure artists; and allows life-long art-based learning (
