Item Aproximações da educação química CTS/CTSA e educação ambiental: um estudo sobre os impactos da chuva ácida no ambiente(2022-10-13) Paz, Danielle Santos da; Amaral, Edenia Maria Ribeiro do; http://lattes.cnpq.br/5241130686153506; http://lattes.cnpq.br/6502843465348417The phenomenon of acid rain is considered, among several researchers, as a serious environmental problem that affects many countries of the world bringing consequences for health and public assets and can be considered a reflection of the dynamics of society, so it is necessary to take measures to identify and reduce its causes and consequences through environmental education. The present work seeks to relate the subject of acid rain with the study of chemistry contents such as inorganic functions: Acids and oxides. It is known the difficulties that teachers have in promoting reflection on environmental issues in the classroom, as well as making a relationship between environmental themes and chemistry contents. Thus, we search the contextualization of the contents of chemistry and environment, bringing the rescue of memories, facts, and situations. Therefore, through the STS/STSE approach we invite students to stand themselves as citizens capable of building their own opinion for an understanding of the social dimension of science, technology, and the environment. Thus, the objective of this work is to develop scientific knowledge through a sequence of teaching and learning on the topic acid rain, using the STS/STSE approach that articulates environmental education to chemistry teaching, and to promote students of basic education, environmental and social awareness. Methodologically, we have developed a teaching and learning sequence for Leonard Waks' responsibility cycle-based STS approach, which elects five criteria to teach ethical issues and values that arise in the education that the STS is present. The didactic sequence was developed for application with a class of 13 students aged between 16 and 17, on their last year of high school, consisted of four didactic moments following the criteria of the Waks responsibility cycle, and the time stipulated for each moment is one lecture corresponding to 50 minutes. For analysis data were considered the students' answers through the proposed activities. From the results of the analysis, we can say that, during the moments proposed in the didactic sequence, the students developed a socio-environmental responsibility that was evident when, during the activities, they were able to relate the theme with the chemistry contents. With this, they were capable to denote a greater knowledge of the phenomenon studied that contributed to the understanding of their roles as citizens who recognize their own rights and duties, responsible for their decisions and for their impacts on society.Item Uma análise do tema chuva ácida nos livros didáticos de Química aprovados no PNLD do ano de 2018(2021-12-22) Silva, Marcio Gomes da; Silva, Suely Alves da; http://lattes.cnpq.br/3497194749381919; http://lattes.cnpq.br/3809853408883171The media in general always address scientific novelties and end up creating a de-mand that must be discussed in the school environment, which always imposes a need for updating both on the part of teachers and of the teaching materials used. Among the materials made available in schools is the textbook, mainly from the Na-tional Textbook Program – PNLD, in force since 1996, and the National Book Pro-gram for High Schools – PNLEM, implemented in 2004 It is through these two pro-grams that students from the public education system, whose schools adhere to them, will receive the book free of charge and must return it after the period of use. Such programs are always aimed at improving the quality of teaching and, it is con-sidered necessary to “improve and expand the didactic resources available for the teaching work and for the effective support for the student's intellectual development” (BRASIL, 2005, p. 32). One of the themes that is always explored by the media re-fers to the global warming of the planet, caused by the excess of certain gases in the air, which accentuate the greenhouse effect, acid rain and other environmental prob-lems. Thus, this is a topic that a Chemistry teacher often needs to give special atten-tion to in their classes. In this sense, our objective in this research was to analyze whether the chemistry textbooks approved in the PNLD for the year 2018 bring the theme acid rain and how it is addressed. Qualitative bibliographic research was car-ried out. Therefore, it was possible to consider that the analysis of textbooks allowed us to conclude that the theme of acid rain is approached in a very simplified way, in most of the analyzed books, and in some they are the threads of certain units. It is considered as positive aspects the fact that the theme of acid rain is frequent in the analyzed books. Thus, they point to the real possibilities of a practical approach to this theme, proposed by the textbook.
