Maths and science programs are therefore designed to arouse curiosity, to raise questions, to model enquiry processes, to be fun, rather than to demonstrate answers. Language programs are embedded in their culture using carefully selected graded language patterns, but leaving the basic instruction to the teacher or to other media such as audio-cassettes or work books. The best history programs are those that use authentic documentary footage of the event. English programs dramatise plays and novels, stimulating reluctant readers to turn to the original. Television can ease the difficulties found by teachers of personal development by providing a focus outside the pupils' own experience, allowing them to deal with intrusive subjects such as child abuse, sexuality or anti-social behaviour.
Television reaches many people at the same time.
It can therefore be an effective leader serving curriculum change. When Commonwealth priorities are set, television programs can bring the approach into every school. For example, in response to the Asian studies initiative, the ABC currently has in production a series to introduce Standard Chinese, and a fortnightly magazine program focusing on Asian current affairs and culture. In developing an adult education television policy, the ABC has a useful history on which to draw - the consultation process with schools' authorities, the realisation of the value of a range of production styles, the understanding of television's unique strengths as a motivator and stimulus, and the experience of providing support materials and teacher education. It also has the example of radio.
