This paper aims to bring to the debate the views and perspectives of Physics undergraduates concerning the introduction of topics and themes of Modern and Contemporary Physics in High School. We pay special attention to the conflict between their initial preparation and the reality of school, either as trainees or teachers. The data was obtained through semi-structured interviews conducted in three public universities, two in Santa Catarina State and one in Minas Gerais State, between the years 2002 and 2007. The conclusions of this work suggest that the debate about the insertion of Modern and Contemporary physics in High School should be expanded mainly into the initial preparation of physics teacher with respect to transfer of content and methodologies from higher education to basic school.
