Introduction to Cognitive Ethnography and Systematic Field Work by G. Mark Schoepfle provides a guide to the fundamentals of cognitive ethnography for qualitative research. A focus of this technique is collecting data from flexible but rigorous interviews. These interviews are flexible because they are designed to be structured around the semantic knowledge being elicited from the speaker, not around some pre-conceived design that is based on the researcher’s background, and they are rigorous because the basic linguistic and semantic structures are shared among all cultures. Written by one of the founders of this technique, this text provides a wealth of concentrated knowledge developed over years to best suit this collaborative and participant-centric research process.
