The classroom is a space for human formation, consisting of diversity and heterogeneity. The pedagogic relations that happen inside are full of subjectivity. With the goal to understand, through empirical data, which are the students and teachers' perceptions about the relationships that unfold in the classroom, we apply a data collection instrument to teachers and students of college classes of Chemistry undergraduate majors in UFMG. Our data analysis shows that the teachers and students' expectations diverge in some ways and, probably that is no pre-established ''contract'' of each one's role. The affectivity in every human relationship and including that which surrounds the teacher/ students' relationship is not well understood. We noted that there is, also, certain ''apprehension'' about involvement when the affective relationship is understood as a relationship of friendship or empathy.
