Item Análise das interações discursivas em uma oficina didática interdisciplinar sobre modelos atômicos(2019-07-10) Rezende, Luana Russana Ferreira; Silveira, Thiago Araújo da; http://lattes.cnpq.br/5110982163642369; http://lattes.cnpq.br/5110982163642369; http://lattes.cnpq.br/4751253414418946The last years, research in chemistry teaching has search to promote resources to overcome the limitations presented in the traditional teaching model and that take into account the articulation between science, technology and the contextualization with the environment that the students are inserted. Therefore, this study analyzes the discursive interactions through a proposal of an interdisciplinary didactic workshop on atomic models with students of the first (1st) year of high school of a public school of the interior state network of Pernambuco. As a foundation, important references were considered about didactic workshops and theoretical orientations on dialogicity, hermeneutics, dialectics and complexity. The research methodology included the collection of data for videography of the five (5) stages of the workshop and subsequently to the analysis of this corpus to evaluate resources, directions and construction of meanings in the dialogues in the context of the interdisciplinary didactic workshops based on the list of observables proposed by Flores (2010),taking into account the theories presented above. As a result of this research, it was possible to identify that the workshop proposal as an active methodology that contributes to the students' socialization process by stimulating the articulation between doing, feeling and acting in a certain activity in sets and for building knowledge through dialogue. It is possible to conclude that the interdisciplinary didactic workshops allow great moments of interaction between student-student and student-teacher, which it should be well planned by the teacher to work the scientific concepts addressing through themes of the student's daily life and to have the decentralization of the speeches.Item Análise da transposição didática do conteúdo de ligação iônica no contexto do ensino médio do Sertão do Pajeú(2019) Lima, Marcelo Igor dos Santos; Silva, Flávia Cristiane Vieira da; http://lattes.cnpq.br/7354496286889274; http://lattes.cnpq.br/1823615287816932The present research had the objective of analyzing the external and internal didactic transposition of the ionic bond content in the context of High School in the Sertão do Pajeú. The notion of didactic transposition, proposed by Yves Chevallard (1991), consists of a process in which knowledge is submitted to a set of modifications, from the academic sphere (knowing wise) to the school environment, in two stages: external (resulting not knowing to be taught) and internal (resulting in the knowledge taught). The research is haracterized asqualitative and was developed in two high schools in the city of Serra TalhadaPE. In this work, the external phase of the transposition was initially analyzed, observing the modifications that the knowledge is submitted to the classroom for the ionic content, investigating the following elements: dessincretization, repersonalization, recontextualization, programmability and publicity. The technique used for data collection was the Bardin Content Analysis (2010). Next, we try to analyze the internal phase of the transposition, observing how two teachers didaticamente transposes the content inside the inner walls of the classroom, analyzing the elements of didactic transposition mentioned above. For the analysis of the elements of the transposition, we are based on the proposal of Brito Menezes (2006), Neves (2009), Guimarães (2009) and Melzer (2012). From the analysis of the external phase of the transposition, we notice that the noosphere follows a pattern in the presentation of the content, associating the ionic bond stabilization with the octet rule, which is a biologically aged content (LIMA et al., 2018) in the students' learning, as Bodner (1991), Taber (1994) and Toma (1997) affirm. Regarding the analysis of the internal phase of transposition, we noticed that teachers usually follow exactly what is proposed in textbooks, which sometimes present concepts far too far from wise knowledge, and ends up transposing this information to the students in a teaching process and learning. From this, it was possible to identify all the elements in the external and internal phase of the transposition, and we emphasize the importance of the teacher in maintaining an epistemological vigilance, in order to reduce the distance between the three spheres of knowledge, transposing information more coherent with the which is scientifically stated, for students.Item Planejamento de uma sequência didática sobre termoquímica com abordagem sociocientífica baseada no perfil conceitual de energia(2019) Silva, Leiliane Alves da; Silva, Flávia Cristiane Vieira da; http://lattes.cnpq.br/7354496286889274; http://lattes.cnpq.br/7921207915607413This monographic research sought to plan a didactic sequence on the content of thermochemistry with an approach in Socio-Scientific Aspects (ASC) based on the conceptual profile of energy. The concept of Energy was chosen for this work because it is a content that is worked in High School, and for presenting different representations and uses, as by the use of the word energy in scientific, school and common sense contexts. We believe it is necessary to consider, in the teaching and learning of the concept of energy, the plurality of ways of thinking, associated with the ways of speaking, attributed to this concept. In this sense, our methodological path was developed in four distinct stages: trend analysis of the last five editions of ENEQ on the content of thermochemistry; structured and unstructured interview with two primary education teachers from Serra Talhada-PE; methodological reference for the elaboration of a Case Study (CE) and methodological reference for proposing a didactic sequence. Regarding the trend analysis, we observed that research in this area is quite diverse and has contributed much to the teaching of chemistry, even though most present discussions about Science - Technology - Society (CTS). The second stage was carried out in two moments: the first one made it possible to identify in the first question the modes of thinking associated with the interviewees' speeches, showing the zones of the conceptual profile of energy, while the second stage included the other questions in a descriptive way, the different teaching techniques and the difficulties associated with understanding the concept of energy, as well as identifying the different ways of thinking about this concept. In the third step, we seek to structure, in a case study, situations and examples mentioned by one of the teachers interviewed, as well as to relate with the ASC. And, finally, for the proposition of the didactic sequence, we take into account the proposed zones of the conceptual energy profile, which were important during the elaboration of the stages of our sequence. As well as the difficulties encountered in the work related to the execution or preposition of sequences and / or didactic instrument on the concept of energy in the teaching and learning of the thermochemistry content, as well as works focused on the conceptual profile, use of EC in the event investigated and the difficulties mentioned by teachers regarding the teaching and learning process of this concept. Throughout the activities, we seek the use of approaches that we consider important for the teaching and learning process and which go beyond the conceptual approach, which is normally used. The use of ASC, the different ways of thinking about the conceptual profile of energy, the difficulties related to the work that dealt with this type of approach and mainly difficulties encountered by the teachers of basic education made possible the construction of a case study. Based on the great researchers in these approaches and the desire to cover important issues for the development of more critical citizens, such as social, environmental and technological issues, and during the course and development of this work, we made some considerations.Item A compreensão de estudantes do ensino médio sobre a temática alimentação saudável a partir de questões sociocientíficas(2019) Menezes, Julyene da Silva; Bezerra, Bruna Herculano da Silva; Silva, Flávia Cristiane Vieira da; http://lattes.cnpq.br/7354496286889274; http://lattes.cnpq.br/1039531472437739; http://lattes.cnpq.br/7609654829609186In the present work we propose to analyze the meanings and meanings, as well as the main preconceptions of the first year students of High School on the theme of healthy eating, through the development and application of a didactic sequence based on STS relations and the approach to questions socio-scientific. For this, we developed a field research of qualitative nature divided into two phases: delimitation of the context and the subjects of the research and elaboration of the didactic sequence and, finally, application of this one. In the first phase, we defined the subjects of the research and the place of application of the sequence, a regular school of the municipality of Serra Talhada-PE participant in the Pedagogical Residence Program of UFRPE / UAST and then we elaborated the didactic sequence in the 5E model. The second phase consisted of the application of the sequence in 15 50-minute classes, addressing the concepts of chemical elements and periodic table within the theme of healthy eating, the biases of nutrients naturally present in foods, impacts that the lack or excess of these bring to health and contamination of food by heavy metals from fertilizers and the breakdown of ore dams (Mariana and Brumadinho). For this purpose, we use materials selected or elaborated specifically for this purpose, such as questionnaire, news, play, summary and two socio-scientific questions based on cases. The data analyzed were constructed in two phases of the sequence, the phase of engagement, in which we sought to map the main conceptions of the students on the subject, and the evaluation phase, where we delimited two episodes of the resolution of the second SSI and analyzed the semantic relations and STS aspects emerging in each one by virtue of the wide variety of constructed data. In general, the proposed sequence proved to be very efficient in addressing the issue, a very wise socio-scientific question, with which the students felt extremely at ease and interested in discussing and thus bringing about a vast heterogeneity of conceptions, senses and meanings the mobilization of aspects relevant to the STS relationship.Item Uma abordagem da radioatividade no ensino médio a partir de um estudo de caso(2019) Belarmino, José Cleuton da Silva; Silva, Cristiane Martins da; http://lattes.cnpq.br/1000796161353860; http://lattes.cnpq.br/3251847005725278Radioactivity is a process in which a nucleus with a certain amount of protons and neutrons can be transformed into another nucleus with different protons and neutrons. We can find various applications and influences of radioactivity in our everyday lives, such as in medicine, industry, agriculture and livestock, making this subject important to be discussed in the classroom. However, despite the relevance of radioactivity in teaching, the subject is often taught in a superficial way, since it is almost always left to be taught in the last months of the academic semester. Given this, this work aims to address this theme with greater emphasis and analyze the development of high school student learning from the application of a case study on the subject in the classroom. This case study was applied to a group of the 3rd year of high school in the technical course of administration of the state technical school Pedro Leão Leal, in the city of São José do Belmonte, Pernambuco. For data collection, an initial questionnaire, a final questionnaire and the presentations of the case solution were used. Through the results obtained, we believe that the use of a case study approaching social issues contextualized on the thematic radioactivity can be an alternative that can contribute to the learning of high school students.Item A experimentação no ensino de química: reflexões a partir dos artigos publicados na seção “experimentação no ensino de química” da Revista Química Nova na Escola no período de 2014-2018(2019) Santos, Cristiane da Silva; Silva, Cristiane Martins da; Bezerra, Bruna Herculano da Silva; http://lattes.cnpq.br/1039531472437739; http://lattes.cnpq.br/1000796161353860This study aims to analyze the main trends regarding the types of experiments present in the articles of the journal Química Nova in the School between the years 2014 to 2018. For this, a search was made in the section on experimentation in the teaching of chemistry, seeking to classify the type experiment was present in the journal. The types of experiments were classified according to Oliveira (2010), which contributes to identify that most of the articles bring proposals of experiments with materials of low cost, and of easy access that can be used by the teacher in high school.
