摘要:This study examines the understanding that preservice teachers have on astronomy, a very relevant educational objective at primary levels. To that end, a sample of students in their final educational level of the Bachelor of Primary Education has been asked about their knowledge related to some significant concepts on the issue of astronomy. A nine questions questionnaire was developed on the basic of the previous research to identify both participants’ understanding and the alternative conceptions that the respondents display on the topic. The conclusions point out significant information regarding the alternative conceptions that the students of the sample have and enable to raise possible ways to improve the astronomical understanding of teachers-to-be.
