This case reports on an innovative method for interviewing, which is semi-structured, and involves the construction of a visual or spatial map. This method is termed Concept Structuring Analysis Task, and it helps the interviewer to gather information on interviewees' thoughts, ideas, and beliefs. The method is especially useful when the researcher wants to uncover the underlying reasons for an interviewee's position or actions in certain situations. Our goal in this case is to help readers to learn the steps involved in planning and implementing the Concept Structuring Analysis Task method. Throughout the case, we provide examples that are taken from our experience in using Concept Structuring Analysis Task for interviewing teachers in order to uncover their perceptions about their professional roles in schools.
