During the period from 2003 to 2005 I worked as a researcher in an elementary school from the Municipal Education Network of Campinas. This paper is about my contact with a teacher whose classes I attended during the school year of 2004. This choice was motivated by this teacher's invitation to participate in her classes on a weekly basis and by the doubts that arised from our dialogue. The condition of a researcher in a classroom, a teacher's expectations in the presence of a researcher in her classroom and the students' senses in the presence of another teacher are questioned. From a socio-historical research, the alterity and the dialogue issues are discussed to foster a reflection about teachers' and researchers' education.
