A abordagem CTS e o ensino investigativo mostram-se essenciais para o desenvolvimento de habilidades e valores necess?rios para o alcance de objetivos t?o nobres e, por isso, se destacam como um caminho para o letramento cient?fico. A partir das hip?teses: (i) Os docentes apresentam dificuldades em elaborar propostas de ensino dentro da abordagem CTS por n?o compreenderem os pressupostos te?ricos, dificultando a incorpora??o dessa abordagem na pr?tica pedag?gica; (ii) O modelo de curso de forma??o oferecido aos professores n?o promove, significativamente, a apropria??o e autonomia necess?ria para incorpora??o da pr?tica da abordagem CTS no planejamento curricular; e (iii) O uso associado de abordagem CTS e investigativa ? eficaz para promover o letramento cient?fico dos alunos. Objetivou-se avaliar como um grupo de professores de Biologia em Natal-RN compreende e aplica a abordagem CTS e investigativa no sentido de favorecer o letramento cient?fico dos estudantes do ensino m?dio. E propor como produto educacional, uma sequ?ncia investigativa com enfoque CTS para o ensino de ecologia com o intuito de averiguar a potencialidade do ensino CTS e investigativo para o letramento cient?fico e contribuir com a forma??o de professores para potencializar essa pr?tica. Os dados foram constru?dos a partir de instrumentos: question?rio explorat?rio e entrevista e sequ?ncia de ensino investigativa na perspectiva CTS sobre conte?dos de ecologia. Este ?ltimo foi elaborado e aplicado para alunos da primeira s?rie de ensino m?dio. Na an?lise dos dados h? ind?cios de que muitos professores apresentam uma vis?o limitada, pra n?o dizer, err?nea acerca do letramento cient?fico. Percebeu-se, que os docentes n?o compreendem, totalmente, o sentido desta terminologia, embora, apontem conhecer elementos intr?nsecos ? mesma. Complementando a resposta, foi evidenciado que o enfoque CTS ? entendido pela maior parte dos docentes, por uma vis?o estreitada na aplicabilidade do conhecimento cient?fico e, na intera??o entre C-T-S. Ademais, evidenciou-se que os cursos de forma??o continuada ofertados pouco t?m contribuindo para supera??o das ideias supracitadas, tornando-as obst?culos que dificultam a efetiva implementa??o da abordagem CTS e o desenvolvimento do letramento cient?fico dos discentes. Os dados obtidos a partir da aplica??o da sequ?ncia de ensino revelaram a importante contribui??o das abordagens CTS e investigativa no desenvolvimento de compet?ncias e habilidades essenciais para o letramento cient?fico. Observou-se nas respostas dos alunos, a aquisi??o de voc?bulos cient?ficos para uso social, atitudes que envolvem a tomada de decis?o respons?vel abrangente ?s problem?ticas ambientais, e desenvolvimento de pensamento cr?tico pelos alunos. === The formation for citizenship and a responsible decision-making in a social environment is not important goals for the educational process. The CTS approach and an investigative teaching are essential for the development of skills and values needed to achieve such noble goals to stand out in a scientific literacy. From the hypotheses: (i) teachers have shown difficulties in elaborating teaching proposals in this CTS approach for not understanding the theoretical assumptions, making difficult to incorporate the approach in pedagogical practice; (ii) The training model course offered to the teachers does not promote the appropriation and autonomy needed for the implementation of the CTS approach in a curricular planning; and (iii) The associated use of the CTS approach is efficient to promote the literacy in scientific text to students. The main goal was to evaluate how a group of Biology teachers in Natal-RN understands and applies the CTS approach in favor of the scientific literacy with high school students. In addition, propose as educational product, an investigative sequence with a CTS approach focused to ecology teaching in order to ascertain the potential of CTS teaching and research for the scientific literacy and to contribute with teachers training to potentialize this practice. The data were created from instruments such as: exploratory questionnaire, interview and sequence of research teaching in the CTS perspective on ecology contents. The last one was developed and applied to students in the first year of high school. There are indications, in the analysis of the data, that many teachers present a limited, if not, misleading, view of scientific literacy. It was noticed, that the teachers do not fully understand the meaning of this terminology, although, they point out to know elements intrinsic to it. Complementing the answer, it was evidenced that the CTS approach is understood by most teachers, in a narrow view of the scientific knowledge applicability and in the interaction between C-T-S. In addition, it was evidenced that the courses of continuous training offered have little to contribute to overcome the ideas listed before, which make them obstacles that difficult the effective implementation of the CTS approach and the development of students' scientific literacy. The data obtained from the application of the teaching sequence revealed an important contribution of the CTS approach in the development of skills and essential abilities for scientific literacy. It was noticed in the students' answers the acquisition of scientific terms for social use, attitudes that involve responsible decision-making related to environmental problems and the development of critical thinking by students.
