Ensino de ecologia sob a perspectiva CTS e investigativa: um caminho para o letramento científico . 2017. 166f.

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.Acesso AbertoSequência de ensino investigativaEnsino de biologiaEducação científicamasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICA: CIÊNCIAS NATURAIS E MATEMÁTICA
