This paper presents a new astronomy self efficacy instrument, composed of two
factors, one relating to learning astronomy content, which we call astronomy
personal self efficacy, and the other relating to the use of astronomical
instrumentation, specifically the use of remote robotic telescopes for data
collection. The latter is referred to as the astronomy instrumental self
efficacy factor. The instrument has been tested for reliability and construct
validity. Reliability testing showed that factor 1 had a Cronbachs alpha of
0.901 and factor 2 had a Cronbachs alpha of 0.937. Construct validity was
established by computing one way analyses of variances, with the p value
suitably protected, using independent variables peripherally related to the
constructs. These analyses demonstrate that both scales possess high construct
validity. The development of this astronomy specific instrument is an important
step in evaluating self efficacy as a precursor to investigating the construct
of science identity in the field of astronomy.
