The authors examine several issues in teaching phenomenology (1) to advanced researchers who are doing qualitative research using phenomenological interview methods in disciplines such as psychology, nursing, or education, and (2) to advanced researchers in the cognitive neurosciences. In these contexts, the term "teaching" needs to be taken in a general and non-didactic way. In the case of the first group, it involves guiding doctoral students in their conception and design of a qualitative methodology that is properly phenomenological. In the case of the second, it is more concerned with explaining the relevance of phenomenology to an audience of experimental scientists via conference presentations or published papers. In both cases, however, the challenge is to make clear to the relevant audience what phenomenology is and how it can relate to what they are doing.
