Abstract
The purpose of this study is to examine the perceptions of pre-service teachers, which directly affect the concepts and ways of thinking of students who are studying Earth science. This work further seeks to identify pre-service Earth science teachers' Earth science-centered ways of thinking regarding the components and the process of water cycle. The concept sketch method was used to survey 50 pre-service teachers who majored in Earth science education at a National Teachers' University. The survey analyzed the preservice teachers' perceptions of a subordinate concept of Earth systems from the applied components of water cycle, and to code the applied concepts with the components of the water cycle based on a subordinate concept of Earth systems including Hydrosphere, Atmosphere, Geosphere, and Biosphere. The preservice teachers only perceived the components of the water cycle as ones in Hydrosphere and Atmosphere. In Biosphere, many participants lack the knowledge about how the actions of plants and animals, and human beings impact the water cycle. About the process of water cycle, the majority of the participants only perceived evaporation and precipitation as the process of cycling: their understanding about the underground flow of water was more lacking than the surface flow.
