Learning about scientific inquiry (SI) is an important aspect of scientific literacy and there is a solid international consensus of what should be learned about it. Learning about SI comprises both the doing of science (process) and knowledge about the nature of scientific inquiry (NOSI). German reform documents promote inquiry generally but do not equally address these two sides of inquiry. This study explores how teachers incorporate learning about SI into laboratory work in the Chemistry classroom. Semi-structured interviews were conducted with 14 secondary school Chemistry teachers (8 of them holding a Ph.D. in Chemistry) from Germany. The results indicate that teaching NOSI is not a primary goal for teachers. Still, some aspects of NOSI seem to be more easily incorporated in the Chemistry classroom, for example, critical testing and hypothesis and prediction. Teachers state 2 main criteria to identify suitable chemical laboratory work for teaching NOSI: adaptable parameters and low level of required content knowledge. Surprisingly, differences can be found between Ph.D. and non-Ph.D. teachers' views on teaching inquiry. The findings of this study can be used to (a) select opportunities for targeted research on teaching NOSI in the Chemistry classroom, (b) inform curriculum material development and (c) give impetus to science teacher education and professional development.
