ROMA, V. N. The Biology textbooks approved by the Brazilian National Program for High School Textbooks (PNLEM 2007/2009): the biological evolution in question. Master of Science Degree Dissertation, Faculdade de Educação, Instituto de Biologia, Instituto de Física, Instituto de Química, Universidade de São Paulo, 2010. During the last 30 years, the research about teaching of biological evolution and evolutionary theories, points out to obstacles in the process of teaching and learning. This can be noted from elementary school level all the way through college level education, and it is present in several countries. Despite others aspects of biological evolution so far investigated, this dissertation is aimed to answer the following question: How are biological evolution and evolutionary theories presented in the organization of the nine Biology textbooks that have been evaluated and recommended by the Brazilian National Program for High School Textbooks (PNLEM 2007/2009)? To answer this question, this study is intended to do the following: (1) Describe the structure and distribution pattern of biological content shared among the nine high school biology textbooks evaluated and recommended by PNLEM (2007/2009), highlighting the biological evolution and evolutionary theory. (2) Describe the sections and/or specific chapters of these textbooks that approach biological evolution and evolutionary theories as objects of study. (3) Localize the evolutionary concepts predetermined over all the textbooks surveyed, to identify the distribution pattern of matters directly involving biological evolution. In order to achieve the goals of the present work, a methodological framework based on a qualitative approach was established by using the following steps: (1) Identification of the name of the sections, chapters, topics and subtopics of the sampled textbooks. (2) Characterization of the specific sections through categories adapted from the literature. (3) Localization of terms (perceptible units) directly related to the concepts evolution, biological evolution, natural selection, biological adaptation, ancestry, genetic variation and phylogeny in the main body of the specific and non-specific sections of the sample textbooks.
