Zusammenfassung

The present study examines students’ conceptions of comets and meteors using qualitative research methods. A total of 35 semi-structured interviews were conducted with students in grades 7 and 9 in Germany, aiming to gain a richer understanding of how learners conceptualize these phenomena. We identified and categorized distinct mental models related to both the appearance (gestalt) and function of comets and meteors, which are reported in detail in this article. Ideas about meteors tend to align with scientific explanations, whereas answers about comets vary widely and often lack a basic understanding. Based on our data, we recommend that educational approaches begin with a clear introduction to physical properties to establish a solid foundation of knowledge. Both aspects of the gestalt and functionality of comets and meteors should be considered and emphasized in the teaching and learning process.
