Blacktown education student Jo Cameron sketched out this science-fiction scenario to help primary school children understand how Aboriginal people sometimes felt.

Ms Cameron's program deals specifically with the Darug people, traditional landholders of parts of western Sydney and the Blue Mountains.

Her program also recently won Amnesty International's NSW Writing for Rights competition.

``The notion that we can just teach Aboriginal history is not necessarily appropriate,'' she said. ``There are specific local groups and we need to teach about the local culture.

``The Darug have maintained a physical presence in Blacktown throughout so it's appropriate to teach students about them.''

She said one problem with teaching about indigenous society was teachers often lacked the time or resources to do it properly.

She said her proposed unit provided information as well as contacts in the Darug community.

``For example, there's a Darug man who could run tours in the national parks and talk to school children about how his people lived. The more students are educated about other people, the more we can enhance community cohesion.''

She said she felt optimistic about improving community relations and hoped her program would contribute to it.

Returning to the hypothetical alien invasion, Ms Cameron asked pupils to consider how they would feel being told they were primitive and had no rights over their classroom.

``What if, instead of taking over our classroom the aliens knocked on our door...?''
