Currently it is expected that science education will enable a more comprehensive conception of the world and of the relationship between scientific knowledge, technology and society. Thus, we seek the science teaching attend around contexts related to science, technology and society (STS). According CTS approaches, the science education should promote learning in the scientific, technological and social fields, from experienced real contexts, generating motivation to students, offering them tools to work as scientifically literate citizens. For this, it becomes crucial to resort to innovative activities and the various methodologies and appropriate teaching materials, and there is a lack of this perspective in general basic education, which drives the practice of an STS approach. Therefore, the aim of this research is the production of an instructional sequence for the exploration of the theme: "The quality of the water in the municipality of Cuité-PB," according to focus CTS in the 2nd year of high school. The choice of this topic is due to the problem caused by the quality of water in this municipality, with the concern to address an issue that came to work the critical / reflective understanding of a real context, in order to sensitize students to the importance of scientific / technological knowledge. The selection criteria of STS subjects were also observed. In this research the materials were produced and applied by the teacher / researcher. For data collection we used the observation and analysis of student records. The results were encouraging in the sense of participation, motivation and skill acquisition. This research contributes to the teaching of science with a focus STS, as well as encourage the use of perspective in new contexts with real questioning

During the last decades the area of science education has discussed issues related to the inclusion of the History and Philosophy of Science (HFS) in the practice of science teaching. Among the arguments put forward in favour of this approach, it is pointed out the possible enhancement of scientific content learning and the understanding of the nature of Science (NoS). In spite of such considerations, we still have a very small number of research papers reporting results of practical interventions that utilize the historical approach, moreover, there is a lack of teaching materials in this perspective. Our work has sought to contribute to this area with regard to two aspects: on the one hand, with the production of didactic material, by drawing up texts on the history of inertia for graduate students. On the other hand, we investigate whether the arguments mentioned above in relation to the didactic use of HFS sustain themselves, in a particular context. We developed and applied a didactic sequence, using the texts that we built, to teach the concept of inertia and discuss selected contents of NoS. The didactic sequence was applied in two graduate classes, one from a course of Geophysics (BSc.) and another from the Physics (teaching formation), both from the Federal University of Rio Grande do Norte (UFRN). An initial survey exposed that students, even having approached the concept of inertia in basic education, presented conceptions of common sense regarding the relationship between force and motion. The questionnaire also allowed us to identify the existence of elements of concepts considered inadequate as regards to NoS. At the end of our research, our data indicated a greater number of positive hits on the issues concerning the concept of inertia. Regarding the aspects of NoS, we were able to identify, in a few cases, a move towards a more appropriate understanding, however, certain distortions persisted, highlighting the limitations of the approach used

Scientific education has been passing by redefinitions, contestations and new contributions from the research on science teaching. One contribution is the idea of science and technology literacy, allowing the citizens not only knowing science but also understand aspects on the construction and motivation of scientific and technological research. In accordance with this idea, there is the Science-Technology-Society (STS) studies which, since the 1970s, has been contributing for science teaching and learning according to the comprehension of the relationships with society in the Western countries of the North. In Brazil, this approach began to gain projection from the 1990s when the first essays on the theme were published. Currently, there is a clear influence of this approach on the national curriculum guidelines, especially for the area of Natural Sciences, and also on the textbooks chosen by the High School National Program (Programa Nacional do Ensino Médio). However, there seems to be a gap in relation to the discussion on the specific curricular component seen in college on this approach. Thus, this study aims at adopting the approach STS, face to the preparation of complimentary educational material on acid and bases concepts studied in the course of General Chemistry of the Natural Sciences graduation program. To this end, it was performed a bibliographical research aiming at making the state-of-the-art in in these concepts in specific literature to science teaching. It is divided in two stages: systematic study (with sixteen journals chosen according to Qualis-Capes and an unsystematic study with direct search in databases and references in the papers of the systematic study. The studies had their content analyzed and the categories chosen a priori were the level of education, the acid-base theory adopted, and the strategy/theoretical frame of reference adopted. A second stage aimed at identifying attitudes and beliefs on STS (Science-Technology-Society) and CSE (Chemistry-Society-Environment) of students in the teacher and technologist training course in three diferent institutions: UTFPR, UFRN and IFRN. In this study, it was used two questionnaires, composed of a Likert scale, semantic differential scale and open questions. The quantitative data reliability was estimated through Cronbach’s alpha method, and tha data were treated according to classic statistics, using the mean as the centrality measures, and the mean deviation as dispersion. The qualitative data were treated according to the content analysis with categories taken from the reading of answers. In the third stage, it was analyzed the presence of STS and CSE content in chapters on acid and bases concepts of nine General Chemistry textbooks, frequently used in graduation programs in public institutions of the state of Rio Grande do Norte. The results showed that there are few proposals of acid and bases teaching, and they are generally aimed at High School or at instrumentation for teaching courses, and no course for General Chemistry. The student’s attitudes and beliefs show the presence of a positivist point of view based on the concept of Science and Technology neutrality and the salvation of its mediation. The books analysis showed just a few content on STS and CSE are found in the studied chapters, and they are generally presented disjointedly in relation to the rest of the main text. In the end, as suggestion to solve the absence of proposals STS in General Chemistry books, as well as the student’s positivist attitudes, it was developed some educational material to be used in the course of General Chemistry at College. The material is structured to introduce a historical view of the concepts preparation, present the use of materials, the industrial and technological processes, and social and environmental consequences of this activities

Nowadays the Distance Learning (DL) is in its fifth generation and New Information and Communication Technologies (NICT) mediate it. In this technological context it is then called Distance e-Learning (DeL). DeL has also in the e-books a potential interactive tool to the collaborative learning. So, this study was accomplished with the purpose of analyzing the e-books developed by SEDIS – Secretaria de Educação a Distância (Department of Distance Learning). This study was performed in two phases: Firstly it was done an exploratory study to check out the reading and the handling of digital e-learning material available to the student-users. These e-books are obtainable on SEDIS Moodle platform. Secondly, it was performed some analysis of an e-book sample by means of the heuristic evaluation. This research aims both to identify potential problems and give some suggestions to solve them. At last it is presented a final report with diagnosis and suggestions for a more applicable design in order to optimize the e-book by means of the distance e-learning usability guidelines

This study arises in the context of physics teacher training and aims, from the speech of the teacher trainer, identify possible pedagogical models and characterize thinking styles present in the course of licentiate in physics of IFRN using the epistemology of Ludwik Fleck. We classify our research as qualitative with an empirical nature, and for the analysis we chose the discursive textual analysis - DTA (MORAES, 2003). The locus of our research will be the licentiate in physics at the Federal Institute of Education, Science and Technology of Rio Grande do Norte - IFRN, Natal-Central Campus and the research subjects, a group of teacher trainers of this course. We interviewed ten teachers, being six from the group dedicated to physics and four from the group dedicated to didactics and pedagogy. From this design, we performed data acquisition consisted of: 1) semi-structured interview, 2) document analysis. On the data analysis, with the support of pedagogical trends that were observed in our study based on the perception of the similarities and differences between the ideas presented by teachers about: education and teaching; ideal teaching practice, teacher's role, learning conceptions, and according to the student and on the ideological thinking of these former teachers on the professional profile of graduates, we noted subsidies to identify evidences of the presence of three distinct thinking styles that interrelate with each other in a considerably intense way. The relevance of the study is presented in the understanding of thinking styles that participate in the dynamics of the course of teacher training in physics, and by consequence, elucidation of a problem pointed out a priori as motivating the research: the difficulty of communicative interaction on educational practices among teacher trainers. We bring Fleck's epistemology as a motivating possibility of dialogue and negotiation, setting thus an instrument of real change, towards the significance of teacher training in physics.

In whole world, including in Brazil, there is an absence of professionals who are able to be present at the moment of birth and give to the newborn the cares that they need to because either an absence of opportunity or inappropriate training to those professionals. This master´s thesis describes a construction and application of a neonatal resuscitation course that uses the problem based learning (PBL) methodology. The course has done in two meetings, one for the tutorial session, and another for practice session. The students were divided in groups of eight students each, under supervision of two teachers with experience in PBL methodology. The experience was considered successfully because there were students involvement and motivation. Some course aspects were rebuilt for its upgrading, like the correct use of methodology and building of custom educational material for students learning necessity. It suggests that the course can be used by the medical and nursing schools and perhaps other kind of health courses.

The present dissertation focuses on specific problems in the educational context: challenges in the construction of historical narratives for pedagogical use as well as the difficult task of using them in the classroom. In this context, we seek to work in teacher training for insertion of History and Philosophy of Science (HPS) in classroom, and historical narratives become mediation elements to advance the dialogue with this specific audience. This initiative is in line with a recurring concern: one of the main challenges related to the didactic transposition of HFC would be the lack of teacher preparation. Historical contents and Nature of Science are still absent in classrooms. Insecurity and lack of knowledge by teachers are often mentioned as factors that contribute to this situation. It is important, therefore, that teachers (active and in training) take part in discussions concerning the inclusion of HPS in classroom. It is relevant that they know examples of historic-philosophical didactic proposals to address science and contents on science, develop skills to adapt them to their specific contexts and to develop their own proposals. It is believed that these issues are significant to undertake conscious initiatives to insert HPS in classrooms. It is considered that adapting educational proposals to particular educational contexts depends on understanding what these proposals indeed mean and how flexible they can be. In order to address these objectives, we elaborated an educational product, a didactic material focused on teacher training, which was used in an extension course at UFRN. The didactic material discusses the role of HPS in Education, Nature of Science and historiographical issues. It presents a series of dialogical activities on aspects of didactic transposition of HPS, especially those regarding historical narratives. A set of historicpedagogical texts on the History of Vacuum and Atmospheric Pressure is used as a mediation element in discussions. We address potential, possibilities and limitations historical narratives. To carry out the course, it was taken into account methodological concerns of so-called action research. There have been expected changes, modifications and effective actions in the own teacher training material in face of the experience of the researcher-lecturer in interactions with the participants of the course as well as in face of impressions reported by the participants. Developments in this direction have been incorporated into the teacher training material.

In educational observed difficulty in train teachers to meet the medium and higher education needs, and one reason for this is the different experiences in the training of educators in relation to those found in the classroom. So often arise criticisms related to relevance and efficiency of degree courses, as regards the performance of its natural mission, which weakens the teacher training. Thus, improving the quality of education is very dependent on the initiatives of teachers, creating teaching alternatives to strengthen their performance in school. From this reflection, it is concluded that teacher training needs new educational proposals that qualify, and so can promote the formation of his students more adequately. Among the educational proposals as alternatives to initial teacher training may use the scientific theater (TC). Considering this possibility, this work has been proposed as investigate and discuss the influence of TC combined with experimentation in the initial training of future teachers in Chemistry who participate in the Groups Fanatics chemistry Theatre (UERN) and Chemistry on Stage (UFRN). Therefore, there was, in a first stage, theatrical essays based on the theater of the oppressed, and written dramaturgical scripts, a collaborative proposal. To incorporate experimentation in chemistry to theater rehearsals, there was a systematic literature search and after content analysis, were selected categories, materials and reagents easily accessible, easy procedures and implementation with low risk of accidents and easy care chemical waste. In the second part we identified: a) the beliefs of student teachers in the use of TC ally trial for initial training of chemistry teachers; b) the influence of TC ally to trial on learning of chemical concepts of high school students who attended the shows; c) the reasons for using or not TC ally to trial by chemistry teachers who participated in the TC group and currently work in the classroom. In this study, questionnaires and interviews were used, compounds, respectively, by a Likert scale and open questions. Quantitative data were analyzed by classical statistics the media, using as centrality measures the average, the concordance argument and the average deviation. Qualitative data were discussed according to content analysis, with categories that emerged from reading the answers. These analyzes concluded that the licensees have a positive view on the use of scientific theater for disclosure of the chemical for use in the learning of chemical concepts, pedagogical and disciplinary knowledge, and to form promotion strategy for research and extension at the University. They credit improvements in their initial training on the use of scientific theater combined with experimentation. The TC provides motivation for the construction of conceptual thinking in an informal way of chemical communication, allowing the student to expand their knowledge, not only favoring the phenomenological approach, but also the construction of chemical knowledge and the internalization of scientific concepts.

The study of solutions is considered very important to chemist’s education because most of the chemical reactions occur in aqueous medium, being also required to understand other subject such as chemical changes, electrochemical and chemical balance. Nevertheless, it is noticed that many students indicate learning difficulties related to the content of solutions, how to pass among the macro-submicroscopic knowledge levels, and how to solve quantitative problems that demanding the establishment of a stoichiometric ratios. This thesis defended considers the use of contextualized teaching strategies about some subject associated to the study of solution, can foster student learning through reflection and understanding of their own difficulties, besides to provide motivation and active participation. The target group is formed by students of the undergraduate distance education with major in chemistry education of the Universidade Federal do Rio Grande do Norte (UFRN), and they were chosen because this education system is expanding and its learning difficulties publications number is reduced as well. Thus, the first methodological stage was to identify the student’s main learning difficulties associated to the study of solutions through literature sources. Next, using an adapted script of the Plano Nacional do Livro Didático para o Ensino Médio (PNLEM, Textbook National Plan for High School), the approach of the content of solutions printed in educational materials used by the target group was analyzed. Afterward, a teaching unit was planned in the last methodological stage and, finally, a new teaching unite was given with a sequence of contextualized activities such as video presentation, dialogued lecture, questionnaires application, exercises, and an experiment, where the target group’s main difficulties related to learning of solution were identified. The participants of the teaching unit activities had some learning difficulties in understand concepts of compound, ion, charge, entropy and solubility, as well as to identify the ion charge, interpret statements, decode tables, use the chemical language, perform mathematical calculations and use concentration units, similar results raised in the literature sources. In order to work on these difficulties, these students were encouraged to expose, question and test their ideas about the phenomenon under study, allowing learn from their mistakes and reflect on the organization strategy of scientific explanatory models they use. Therefore, activities and information about learning difficulties presented in this thesis need to be critical reflection object, because it can help both students in the process of acquiring knowledge about the content of solutions and professors in the planning of their lessons.

The educational games can act as a complementary tool in the teaching and learning as play an important role in the interaction of the student with knowledge, and encourage interrelationship between students and motivate them by the pursuit of knowledge. This research is intended to analyze the evidence of the students of distance education applied to semesters 2011.2 and 2012.2 for the purpose of to catalog the mistakes presented by the students, the contents of stereochemistry that attended the Chemistry of Life discipline. From the presented mistekes, develop an educational game, "walking the stereochemistry", addressing that content. The choice of stereochemistry content was due to the low number of found work in the literature, and for being one of organic chemistry content that generates learning difficulties, as it requires a mental visualization and manipulation of molecular structures, besides require observation and comparison ability by the students. The game was applied of Life Chemistry discipline of Nova Cruz Polo in semester 2013.2, with intention to verify the viability and applicability this tool for the development of motivation ability by the pursuit of knowledge by the students, as well as complement the didactical materials of the DE. Then, It was made available on the course page an opinion questionnaire to the participants of the game, as a way of to investigate the opinion their about the proposed strategy. To diagnose the contributions of the game on student learning, it was taken a comparative analysis of stereochemistry issues contained in didactic tests applied in 2013.2 semester students participating and not participating of the polo of Nova Cruz and was also compared with the tests applied at the poles of Extremoz, Currais Novos, Lajes and Caico. So the game can be considered an important resource to complement the teaching materials of distance education, because awoke the motivation for the search of knowledge and contributes to the learning of stereochemistry content.

Specific educational material production for a group of level IV – 8th and 9th years of Youth and Adults Education, having as starting point the reading of a series of letter of correspondence between Câmara Cascudo and Mário de Andrade in the 1920s, and the verification of the way the dialog between the two authors reveals elements that transpire themselves in the tale entitled “Piá não sofre? Sofre”, from the book Os contos de Belazarte, de Mário de Andrade. The educational material production was preceded by the analysis of the selected tale, which will be studied along with some of the letters, in an analysis of the textual, discursive and semantic features of the text in representation of these both genres: letter and tale. The selected tale was written between 1923 and 1926, dates close to the years when the author came by Rio Grande do Norte state, in the years from 1927 to 1929, accompanied by Câmara Cascudo, being also this period that there are records of letters in the set of correspondence between them. To the reading of the selected material, it was used theoretical references from literature and literary historiography, especially the history of Brazilian modernist movement. To the production of the educational material, it was chosen as theoretical reference the accumulated knowledge in the area of literature teaching, literacy and the recommendations of the Brazilian National Curriculum Parameters. The methodology in this study was constructed from the theoretical references and had as basic support the study of didactic sequences from which a specific thematic unit got its shape from, required by the analyzed material and tested in a classroom.

This thesis is a writing of (d)enunciation because it reveals the language experiencies of those individuals who take, in social school space, the social role of the teacher and of the student, for some reason, they feel restrained by a demand which prevents them of teaching and learning how to write – and, even, their own writing. On this basis, we consider some questions concerning Benveniste‘s theory of enunciation and the teaching and learning process in Portuguese from the triad among teacher – teaching of writing/ knowledge – student, making this theoretical area closer to the pedagogical one. We support in the working hypothesis that is based on the position of the loosening of this triad has its effects in the process of intervention-interference to the point where it does not leave a scar which can remain working on productive effects on the student‘s writing. As a consequence, we show two findings which allow us to think the teaching of writing in Portuguese is a space for writing creativity in such a way it reveals itself as a sine qua non condition for the institutionalized and subjective writing. The first finding is that taking genre as a model has some implications in the teaching and learning process of writing according to the instructions of the official documents. The second finding, as a result of the first one, is the assumption that genre is at the same time a model and a transgression and taking it as a (ex)sample opens space for writing creativity which ―is a transposition of the interior language‖ (BENVENISTE, 2014 [1968-1969], p. 132) in a way this creativity makes it intelligible and highlights what is a model (interactiveness) and a transgression (inventiveness). From such findings, we organize our heterogeneous corpus according to these procedures: recording the classes in audio; recording the interviews we made with teachers and students in audio; and constituting an archive with the students‘ writing production. From this corpus, we analyzed the (d)enunciative mo(ve)ments in the teacher – teaching of writing/ knowledge – student triad and the history of (d)enunciations, of language experiences. Besides, we analyzed the teacher‘s discourse in relation to the way he plans his classes based on the knowledge that must be taught and his own way of managing this knowledge in order to understand his interference in his students‘ writings. Our analyses (re)affirm that when the loosening of the triad happens, the students become lost, what makes them unable of working upon their own writing epilinguisticaly. Because of it, schools have lost their specificity as a place for teaching students how to read and write as they open space for training, only. On this basis, we consider that the effect of such a loosening generates complaints and denunciations. Therefore, based on such (d)enunciations, we present the Primary sketches of a proposition for intervention-interference in teaching how to write and we aim at introducing much knowledge to teachers and students in order to allow them to think about possible ways out.

This work aimed at analyzing the speeches constructed about motivation by English teachers who teach at public state schools in the interior of Minas Gerais. We aimed at delineating the concept of subject underlying the subjects’ notion of motivation and identifying the role that the English teacher attributes to himself and to the student when he/she enunciates on motivational issues, problematizing the possible consequences of these issues for some English teachers while working in public schools. In order to do so, our investigation made use of theoretical assumptions from Applied Linguistics and Discourse Analysis. The theoretical fundamentation deriving from Bakhtin Circle as well as from Michel Pecheux’s theoretical basis were also very relevant for this research. The intersection of these studying fields entails a theoretical construction that considers the voices of those who live the social practice (MOITA LOPES, 2006), which allows one to see the subjects through their heterogeneity, fluidity and fragmentation. Moreover, it generates knowledge about language in its political, ideological, social and historical aspects. AREDA (SERRANI, 1998) was used as a theoretical and methodological framework for data collection. In our analysis, we considered the voices and the conditions of production that constitute 5 English teachers and, from some selected speeches extracted from their discursive production, some notions as intra and interdiscourse, discursive resonance, discursive memory, among others, can be seen interwoven. We hypothesize that the production of meaning deriving from these English teachers comes from a cleavage between the interdiscursivity about motivation and their position in relation to the English language. Some of these teachers’ discursive inscriptions were delineated as they follow: i) the silenced motivation, in which the teachers come up with several voices, repeating what that has already been said about motivation through silence by excess; also, through an inscription in a process of anomy, the English teachers silence motivation, as they come up with other sayings, in an anomic order, denying their identification with their mother tongue and culture because of a desire to learn the foreign language and culture; ii) the motivation in/from/ by others that resounds, in the way the teachers speak, a relation of alterity on what, in/from desire of other relations (colleagues, students, teaching materials, media, etc.), other forms and alternatives are established as a guarantee of students’ motivation; the teachers are also inscripted in in-service practice training as a space of educational development, because they imagine that the experience of the in-service practice alone, which excludes the educational instruction from the Languages course in which they graduated/were graduating at, taught them how to motivate the students; iii) the motivation as a will of power/knowledge, which means there seems to be teachers’ inscription in the relationship between power and knowledge (Foucault, 1996), disconsidering the conflicts that constitute the English classroom to say that there is a control of the English teaching and learning process and, as a result, they also sustain that they hold control over how to motivate; furthermore, the presence of a resonant voice, whose effect is given by an inscription on the (illusion of) completeness can be seen, because the English teachers believe that while motivating their students, this motivation will provide them with all the missing elements, which would mean that when they motivate students, they would be able to fulfill all the gaps in their learning process.
