Tornando-se professor de ciências: crenças e conflitos

The present study is a qualitative research of one case study kind that followed the route of one High- School Physics teacher who was starting her teaching career in 1998, but was still finishing her course on initial formation of Physics teachers. We have used the Practice of Physics Teaching I and II disciplines of the initial formation course as a background, so we could approach the educational beliefs of our research subject. To follow this teacher we have utilized the new teachers professional development concept. This concept involves detection, evolution and conflict solving, and professionals concerns inherent to teachers development. The data available to us, which we analyzed in order to understand the developing routes of this teacher was their own written materials, two sets of interviews in different periods, and the recording of images of the school year’s second semester at the University where the formation discipline that we followed took place. Through interpreting the analyses originated from the qualitative method we tried to establish a professional development route for this teacher, trying to contribute for a better understanding of the problems resulting from this transition stage from being a student of the initial formation and at the same time, experiencing already the professional conflicts and concerns. The initial formation program evaluated in this study was the undergraduate course in Physics of the Faculdade de Educação - Universidade de São Paulo. The results showed that the three studied teachers dealt with her conflicts and professional concerns, utilizing particular strategies that derived from the histories of her life, the way she opts for her career, and especially for her pre-existent educational beliefs. O presente estudo é uma pesquisa qualitativa do tipo estudo de caso que acompanhou a trajetória de uma professora de física do Ensino Médio que estava começando a dar aulas no ano de 1998, mas ainda concluindo seu curso de formação inicial de professores de física. Usamos as disciplinas de Prática de Ensino de Física I e II, do curso de formação inicial, como pano de fundo para que pudéssemos nos aproximar das crenças educacionais do nosso sujeito da pesquisa. Ao acompanhar essa professora, tanto na condição de aluna do curso de formação inicial como também na condição de professora novata, utilizamos o conceito de desenvolvimento profissional de professores iniciantes que envolve a detecção, a evolução e formas
