Knowing the essential importance of the teacher at the educational process since he/she is the mediator on knowledge gathering by the scholars and continued formation meaning on that process, we hereby propose to investigate and compare what Math teachers think about their professional role, the kind of continued formation they receive and their development on teacher s knowledge and doing; to gather and compare what do Math teachers know about young people at public and private schools and their demands and as which find out if they link with the way as their students are taught. To develop our comparative research, we chose a qualitative focus and an investigation of ethnographic type. We took as the subject four Math teachers that work with high school 1st and 2nd grades in public and private schools, morning and afternoon shifts and license titles. The research results reveal differences in structural matter between the spaces, but the comparisons between teacher doings and knowledge reveal that the differences refer to the sort of formation and how often do the teachers search for it. Nevertheless, the reports pointed to continued lecturing formation offering and consistence problems and these reflect on their work and on its basis. The knowledge about youth and adolescence, such as theoric and methodological knowledge that lead their practices, are revealers of teachers difficulties in developing their activities according to the target public and nowadays educational demands / O presente trabalho delimitou como objeto de estudo as pr?ticas pedag?gicas e forma??o docente continuada de professores de Matem?tica no Ensino M?dio. Entendendo ser o professor de grande relev?ncia no processo educativo por ser o mediador na apreens?o de saberes por parte dos educandos e da import?ncia que tem a forma??o continuada neste processo, procedeu-se ? investiga??o e compara??o sobre o que pensam os professores de sua atua??o profissional, o tipo de forma??o continuada que recebem e seus desdobramentos nos saberes e fazeres docentes. Buscou-se, tamb?m, apreender e comparar o que sabem os professores de Matem?tica das escolas p?blica e privada sobre juventude e suas demandas e como tal saber se relaciona com a forma como ensinam seus alunos. Para o desenvolvimento dessa pesquisa de car?ter comparativo, optou-se pelo enfoque qualitativo e investiga??o do tipo etnogr?fico. Foram tomados como sujeitos 04 professores de Matem?tica que atuam nas 1? e 2? s?ries do Ensino M?dio em escolas p?blicas e privadas, nos turnos matutino e vespertino e com titula??o de licenciados. Os resultados dessa pesquisa revelaram diferen?as de ?mbito estrutural entre os espa?os, mas as compara??es entre os fazeres e saberes docentes revelaram que as diferen?as existentes se referem mais ao tipo de forma??o e freq??ncia com que os professores a buscam. No entanto, todos os relatos apontaram para problemas quanto ao oferecimento e consist?ncia da forma??o docente continuada e isso se reflete em suas pr?ticas e de como as fundamentam. O entendimento sobre juventude e adolesc?ncia, bem como os saberes te?rico-metodol?gicos que norteiam suas pr?ticas s?o reveladores das dificuldades sentidas pelos professores em desenvolver seus fazeres de acordo com o p?blico ao qual se destina e com as demandas educacionais atuais.
