Problemática socioambiental sob o olhar da abordagem CTS: uma proposta para o ensino de Ciências na Educação de Jovens e Adultos
(Universidade Federal do Pará, 2016-12-06) SOUSA, Alice dos Santos; CONTENTE, Ariadne da Costa Peres; http://lattes.cnpq.br/5424406285707749
This research came from reflections on the teaching of science developed in the context of the Youth and Adult Education (EJA), and the recognition that the traditional approach of scientific content hinders the construction of knowledge by the students, because it ignores previous knowledge, with disarticulated the social, political, economic and technological. In this sense, we consider important to develop a proposal in which the approach of scientific content in EJA leave a problem situation addressed in CTS perspective, we believe that this can lead young people and adults to appropriate scientific knowledge and to develop the critical capacity for decision-making. From this, we seek answers to the following questions: science classes with CTS approach enables the construction of scientific knowledge by students of EJA? Students of adult education is able to grasp scientific knowledge related to the problems of their daily lives? And the scientific content approach starting from a problem situation allows the development of an active, reflective and critical stance by the student EJA? This study was a qualitative research, with a focus on action research. For analysis, we adopted the discursive textual analysis as a process aimed at producing new insights into phenomena and speeches. The data that constitute the corpus of the research were built in the classroom with the extracts of the most significant speeches of students. The results showed that it is necessary to insist on educational proposals that promote links between school subjects and everyday actions, this being an educational trend that enables the teacher to develop the curricula of interdisciplinary and contextualized way, exploring social, technological and environmental aspects in teaching sciences from a problem situation. Thus, in addition to allowing the exploration of issues that are under discussion in the media, the adoption of the CTS approach enables greater interaction between the triangulation: teacherstudent- knowledge, given that everyone can participate actively in the construction process knowledge through dialogues that develop during the exploration of this theme. Through research it was possible to build a new look in classes focused on science education with students of EJA.

Tecnologia ambiental na gestão de recursos naturais: o “voo” tecnológico da fiscalização mineral do estado do Pará
(Universidade Federal do Pará, 2015-11-18) SAMPAIO FILHO, Inaldo de Sousa; FARIAS, André Luís Assunção de; http://lattes.cnpq.br/5310171409459863
The technology features of unmanned aerial vehicles (UAVs) potentiate its civil use in several areas. Glimpsing the potential use in mineral inspection area of this technology, it was acquired by the federal competence agency in the granting and mineral inspection of Pará State. However, the availability and the fact to acquire such technology are not sufficient for success in their use. The success or failure is directly related to the way that this technology is managed. This research aimed to analyze the process of incorporating this technology as mineral inspection tool by the National Mineral Production Department of Pará State (DNPM-PA). For this purpose, used methodological approach based on technological innovation management processes of Nuchera, COTEC Foundation and Tidd and Bessant. About the research procedures, bibliographical and documentary surveys were conducted, interviews and application of free questionnaires for case study. The research development showed that, despite the potential of UAVs as mineral inspection tool, the technology is not getting incorporated strategically of Pará State. Stands out that the inspection is a fundamental part in the natural resources management, acting on the control and monitoring of environmental impacts from the mining activity, and that the spread of this technology will contribute to the strengthening of inspection activities in the state, since the insertion of UAVs is performed within the technological innovation management concepts.
