With the increased importance given to astronomy education, the number of studies in this field has increased. In Turkey and abroad, a large number of studies have aimed at revealing the astronomy concepts pre-service teachers have. In this study, a literature-aided multiple-choice test of 31 questions has been developed. After the revision of the survey by 3 physics experts, reliability studies have been done with 55 pre-service science teachers, and ¦Á=0.61 has been obtained. This questionnaire was applied to 78 pre-service mathematics teachers before the instruction. After a 10- week instruction, the questionnaire was carried out again with the same subjects. A significant difference has been found between the results of pre and post-tests of four sections and the general questionnaire. It can be said that instruction has lead to a conceptual change. %K Pre-service teachers %K astronomy %K misconception %K conceptual change. %U http://dergi.omu.edu.tr/index.php/EDUCATION/article/viewFile/1311/1208
