The main goal of this research is to evaluate the proposal to introduce Modern and Contemporary Physics (MCP) in Brazilian secondary and high schools. Our evaluation presupposes that teachers assume sometimes unconsciously, that the MCP basis theory is essentially misunderstood. In 2007, we investigate five in-service Brazilian Northeastern physics teachers discourses, in order to comprehend their perspectives and possibilities to introduce MCP in their classes, as well as, how these possibilities are related to their professional backgrounds. Teachers' discourses were analyzed using as referential the French Discourse Analysis and Critical Educational Theory. We realized that the interviewed teachers, even though attributing relevant role in introducing PMC in that school level, are not facing this challenge.
