Inquiry-based science education (IBSE) is a complex instructional approach, which requires a great deal of specific knowledge and skill on the part of the teacher. In order to prepare pre-service teachers to deal with this complexity, it is recommendable to gradually introduce individual aspects of IBSE, such as goals for IBSE, the Levels of IBSE and measures for structuring and guiding IBSE one after another. In this talk, I will present how individual aspects of IBSE are included within the curriculum for pre-service teacher education in chemistry at the University of Vienna (Austria). For this purpose, I will refer to the development of three specific learning environments: units following the 5E instructional model, tasks including scaffolding measures for independent work and interaction boxes including tasks and materials for individual learning. Referring to these three examples, I will discuss both the goals we strive to achieve and the challenges we as well as the pre-service teachers are confronted with when introducing these types of teaching methods.
