Abstract
Statement of Research Problem:
The formal research problem was:
Is the planetarium a more effective teaching device
than a combination of the classroom chalkboard and
celestial globe In the teaching of selected
astronomical concepts in terms of the immediate
attainment and retention of specified cognitive
behavioural objectives and the attainment of specified
affective behavioural objectives?
The planetarium teaching situation was compared to the classroom
chalkboard and celestial globe teaching situation in the teaching of
selected astronomical concepts. The classroom chalkboard and celestial
globe teaching situation was chosen for comparison because it represented
a standard adequately equipped teaching situation for the astronomical
concepts involved.
The astronomical concepts are the diurnal and yearly motions of
stars, the superior planets and the sun, and the celestial sphere and
precession. The behavioural objectives are stated in a discussion of
the evaluation instrument.
