These are also the same research results in Thailand, for example; students faced difficulty
Factors believed to cause these difficulties include teachers’ low capability in teaching astronomy and instructional models which did not support students’ understanding. Dahsah, Phonphok, Pruekpramool, Sangpradit, and Sukonthachat (2012) also
found that most of Thai secondary school students (grades 7-12) had no idea about sizes and distance of Earth-Moon-Sun (EMS) models. The students both underestimated and overestimated the distances, and overestimated the sizes. Banyong (2013) discussed that the students’ prior mental representation of the celestial sphere and planetary motions could not be related their knowledge to daily phenomena.
