Abstract
The learning of pupils from Years 5 and 6 (9-and 10-year-olds) when taught with the aid of dome and computer planetaria was investigated. The two kinds of planetarium were found to be equally effective, although the learning was confined to female pupils. It is suggested that the use of planetaria might enable females to catch up with males in areas of astronomy which make heavy demands on spatial ability. Substantial learning also took place in the pre-service education students who led the planetaria sessions.
