Creativity plays a very important role in education. Most of educational systems support creativity as relevant competence for the 21st century. According to the findings of experts, teachers' creativity is important for the development of students' creativity. We introduce a theoretical base of creativity and styles of creativity. Based on our research, inquiry-based science education (IBSE) seems to be the appropriate way for creativity development of teachers as well as students. Every teacher and student is more or less creative and IBSE enables individual attitudes in the development of creativity. The core principles of IBSE such as student activities, linking information into a meaningful context, developing critical thinking, promoting positive attitudes towards science and motivation correspond to basic components of creativity. Similarly, IBSE involves basic processes that give rise to creativity, which is delineated by R. Sternberg. We present reasons why IBSE is suitable for development of teachers' creativity.
