S?o consequ?ncias de uma abordagem educativa de transmiss?o/recep??o, que frequentemente se demonstram insuficientes na realiza??o de uma contextualiza??o. Logo, a utilidade destes saberes se restringe a reprodu??o do que foi dito pelo professor. Isto acaba colocando os educandos como meros espectadores na produ??o do conhecimento. Repensar e propor interven??es no papel que cada indiv?duo envolvido no processo de ensino e aprendizagem apresenta, ? uma constante necessidade, visto as mudan?as recorrentes nos objetivos educacionais. Esse estudo procurou implementar uma proposta de ensino de conte?do de qu?mica, intentando envolver o educando no processo de aprendizagem de modo dial?gico, na busca de torn?-lo mais aut?nomo. Tamb?m tenta auxiliar os educadores em sua atua??o profissional. Para tanto, nos baseamos em aportes te?ricos que sustentam nossa percep??o, como as dificuldades de aprendizagem e alguns pressupostos do educador Paulo Freire que fundamentam a pr?tica educativa problematizadora-dial?gica. A din?mica dos Tr?s Momentos Pedag?gicos de Delizoicov, foi o referencial te?rico-metodol?gico da sequ?ncia de atividades de uma unidade did?tica para o ensino de ?cidos graxos e gorduras. A proposta foi implementada durante o segundo semestre de 2015, no Centro de Educa??o de Jovens e Adultos Professor Felipe Guerra, com uma turma do n?vel de ensino m?dio, na modalidade EJA. Quanto a abordagem do problema de estudo, buscamos seguir alguns dos pressupostos da pesquisa qualitativa, que fez uso dos instrumentos question?rio, observa??o e documentos, que foram as atividades que compunham a proposta de ensino e o projeto pedag?gico da escola. As considera??es que tecemos ante as respostas obtidas, foi a percept?vel mudan?a qualitativa na postura dos educandos, buscando participar das discuss?es, trazendo sua percep??o sobre os conte?dos qu?micos trabalhados, se envolvendo dialogicamente na constru??o de seus conhecimentos. / The systematized knowledge that is given to students at school, usually does not go beyond this space. These are consequences of an educational transmission / reception approach, which is often insufficient for contextualisation. Therefore, the utility of these knowledge is restricted to the reproduction of what has been said by the teacher. This ends up putting the students as mere spectators in the production of knowledge. Rethinking and proposing interventions in the role that each individual involved in the teaching and learning process presents, is a constant need, given the recurring changes in educational goals. This study tried to implement a proposal of teaching of chemical content, trying to involve the learner in the process of learning in a dialogical way, in the quest to make it more autonomous. It also tries to help educators in their professional activities. For that, we base ourselves on theoretical contributions that support our perception, such as the learning difficulties and some assumptions of the educator Paulo Freire that base the educational practice problematizadora-dialogical. The dynamics of Delizoicov's Three Pedagogical Moments was the theoretical-methodological reference of the sequence of activities of a didactic unit for the teaching of fatty acids and fats. The proposal was implemented during the second semester of 2015, in the Youth and Adult Education Center Professor Felipe Guerra, with a high school class, in the EJA modality. Regarding the approach to the study problem, we sought to follow some of the assumptions of the qualitative research, which used the questionnaire, observation and documents instruments, which were the activities that made up the teaching proposal and the pedagogical project of the school. The considerations we made in response to the answers were the perceptible qualitative change in the students' posture, seeking to participate in the discussions, bringing their perception about the chemical contents worked, and becoming involved in the construction of their knowledge.

For this purpose, a proposal was presented to help chemistry teachers to provide students with a better understanding of more meaningful learning. The Teaching of Chemistry in Basic Education presents several challenges regarding the introduction of concepts related to the structure of matter. The approach of this project is centered in the interaction between the Astronomy and the Teaching of Chemistry, in an interdisciplinary perspective with focus in the course of didactic engineering. It is premised that this approach may attract the interest of high school students. The methodology was developed in the classrooms of the Luiz Eduardo Magalh?es College in Feira de Santana-BA. The use of a learning sequence, centered on experimental and observational phenomena where the student's performance is intensified by the possibility of self-regulation and confrontation with the proposed situations, enabled an evolution of strategies, enhancing students' cognition. In an enveloping and structured way in its four phases, the course of didactic engineering contributed to progress in improving teaching and learning, since the agreed proposal was executed and indicates that it is possible to favor the learning of concepts of Teaching Chemistry with emphasis to topics, motivating Students to learn / O principal objetivo deste trabalho foi descrever os conceitos de Modelos At?micos, dentro do cen?rio do ensino de rea??es qu?micas, relacionando-os empiricamente com os processos de luminesc?ncia qu?mica e contextualizados com o fen?meno das Auroras planet?rias. Para o efeito, foi apresentada uma proposta para ajudar os professores de qu?mica a oferecer aos alunos uma melhor compreens?o da aprendizagem mais significativa. O Ensino de Qu?mica na Educa??o B?sica apresenta v?rios desafios em rela??o ? introdu??o de conceitos relacionados ? estrutura da mat?ria. A abordagem deste projeto est? centrada na intera??o entre a Astronomia e o Ensino de Qu?mica, em uma perspectiva interdisciplinar com foco no curso da engenharia did?tica. Pretende-se que esta abordagem possa atrair o interesse dos alunos do ensino m?dio. A metodologia foi desenvolvida nas salas de aula do Col?gio Luiz Eduardo Magalh?es em Feira de Santana-BA. O uso de uma seq??ncia de aprendizagem, centrada em fen?menos experimentais e observacionais, onde o desempenho do aluno ? intensificado pela possibilidade de auto-regula??o e confronto com as situa??es propostas, permitiu uma evolu??o das estrat?gias, aprimorando a cogni??o dos estudantes. De forma envolvente e estruturada em suas quatro fases, o curso de engenharia did?tica contribuiu para o progresso na melhoria do ensino e da aprendizagem, uma vez que a proposta acordada foi executada e indica que ? poss?vel favorecer a aprendizagem de conceitos de Qu?mica de Ensino com ?nfase em t?picos, motivando esudantes para aprender

The area of chemical education has been growing more and more, and an important aspect that has been researching this area is about the learning difficulties of students. The approach of the themes atomic structure and chemical bonds are developed in high school and have many problems that are often brought to higher education becoming an obstacle to the advancement of learning. It is necessary for these initial themes - the atomic structure and chemical bonds - are well understood by the student to the other contents of Chemistry will be understood more easily. This paper aims to describe, analyze errors and difficulties presented in the assessments of the discipline Atomic and Molecular Architecture, the students of the degree course in Chemistry - EAD, with respect to the contents of " Atomic Structure and Chemical Bonding ", by of the assessments made by the students and the Virtual Learning Environment (VLE), taking into account the activities , discussion forum and access to materials . AVA allows obtaining reports which were used to analyze regarding access / participation to assess their contribution to learning and its relation to the final result (pass / fail). It was observed that the most frequent errors in the assessments are related to the early part of the chemistry that is the understanding of atomic structure and evolution models. Students who accessed the extra material and participated in the activities and forums were students who achieved success in the course. Ie, the difficulties were emerging and the use of available teaching strategies, students could minimize such difficulties, making their performance in activities and assessments were better. Was also observed by attending the AVA, the discipline began with a large withdrawal from the page access as well as the frequency of face- evidence from observation in Listing presence of classroom assessments / O campo da educa??o ? muito rico e nos possibilita a investiga??o em v?rios aspectos.

In that context, the investigations concerning teacher s knowledge represent an important contribution, as they aim to identify and to rescue the base of knowledge that sustains the teacher s profession. In particular, the reflections and propositions of Lee Shulman have been constitute a fundamental subsidy to the teacher s professionalization in the sense of harnessing the pedagogic knowledge to the content s knowledge, establishing the pedagogic knowledge of the content that characterizes and differentiates the teacher and the bachelor in a certain field of knowledge. Among the indispensable knowledge for the Chemistry teacher's professional practice, in this research we have pointed out the pertinence of the knowledge on the use of models in Chemistry classes in the middle and high school. Those knowledges regard the comprehension of students concerning the understanding and models elaborated in science and the models implemented in the Chemistry teaching, as well as the abilities to plan didactic situations that use models. In this research, we aimed to identify the contributions and barriers during the Chemistry teacher education, in UFRN, in relation to the construction of knowledge that subsidize training teachers in the elaboration of teaching activities that involve the use of models. The investigation was accomplished in UFRN, in the Course of Degree in Chemistry, along with 13 student teachers that studied the subject Practice of Chemistry Teaching. For this research, the following instruments were used: questionnaires with open and closed questions, elaboration of a plan of activities for the Chemistry teaching and an interview to answer the established study s questions. The data was analyzed in an established criteria, classified and tabled. The results showed that the student teachers representations regarding scientific knowledge contemplated, among other topics, the idea of a method for his/her construction. In some cases, the models role was emphasized in that construction, as well as the social dimension in the validation of that knowledge. The scientific models were highlighted by most of the student teachers, as a representation method to explain, understand and interpret the chemical phenomena. On the other hand, the didactic models stood out, in most of cases, as a method of aiding the Chemistry students of the Basic Education to understand the scientific models. The representations regarding those categories contemplated important aspects, although in a superficial way, reflecting the limitations of reflections during the formative process. In the elaboration of teaching activities that use models, difficulties were evidenced, in the process of plan construction, relative to the didactic structure and to the proposition of activities that contemplated models, although the student teachers have mobilized different elements regarding the pedagogic knowledge of the content. Such verifications evidence the urge for the teacher development programs to promote changes in the teacher education in order to propitiate, during this process, reflections, discussions and propositions of activities regarding categories highlighted in this research, contributing to the construction of initial elements regarding the pedagogic knowledge of the content that will be developed throughout teaching, therefore corroborating to the teacher s professionalization / Nos ?ltimos vinte anos, as pesquisas voltadas profissionaliza??o docente t?m crescido de modo expressivo. Nesse contexto, as investiga??es acerca dos saberes docentes representam uma importante contribui??o, visto que buscam identificar e resgatar a base de conhecimento que sustenta a profiss?o docente. Em particular, as reflex?es e proposi??es de Lee Shulman t?m constitu?do um subs?dio fundamental ? profissionaliza??o dos professores no sentido de atrelar os saberes pedag?gicos aos do conte?do, estabelecendo o conhecimento pedag?gico do conte?do que caracteriza e diferencia o professor e o bacharel em determinada ?rea de conhecimento. Entre os saberes imprescind?veis ao exerc?cio profissional do professor de Qu?mica, salientamos, nesta pesquisa, a pertin?ncia dos relativos ao uso de modelos nas aulas de Qu?mica nos ensinos fundamental e m?dio. Esses saberes s?o referentes ? compreens?o dos licenciandos acerca do conhecimento e modelos elaborados na ci?ncia e dos modelos adotados no ensino de Qu?mica, assim como as habilidades para planejar situa??es did?ticas que utilizem modelos. Nesta pesquisa, buscamos identificar as contribui??es e entraves, durante a forma??o inicial de professores de Qu?mica, na UFRN, em rela??o ? constru??o de saberes que subsidiem os licenciandos na elabora??o de atividades de ensino que envolvam a utiliza??o de modelos. A investiga??o foi realizada na UFRN, no Curso de Licenciatura em Qu?mica, junto a 13 licenciandos que cursavam a disciplina de Pr?tica de Ensino de Qu?mica. Para esta pesquisa, foram utilizados os seguintes instrumentos: question?rios com perguntas abertas e fechadas, elabora??o de um plano de atividades para o ensino de Qu?mica e entrevista de modo a responder as quest?es de estudo estabelecidas. Os dados obtidos foram analisados a partir de crit?rios estabelecidos, categorizados e tabelados. Os resultados sinalizam que as representa??es dos licenciandos referentes ao conhecimento cient?fico contemplavam, entre outras quest?es, a id?ia de um m?todo para a sua constru??o. Em alguns casos, foi ressaltado o papel dos modelos nessa constru??o, bem como a dimens?o social na valida??o desse conhecimento. Os modelos cient?ficos foram destacados, pela maioria dos licenciandos, como uma forma de representa??o com finalidade de explicar, compreender e interpretar os fen?menos qu?micos. J? os modelos did?ticos foram ressaltados, na maioria dos casos, como uma forma de auxiliar os alunos de Qu?mica da Educa??o B?sica a compreender os modelos cient?ficos. As representa??es referentes a essas categorias contemplaram aspectos importantes, embora de modo superficial, refletindo as limita??es de reflex?es nesse sentido durante o processo formativo. Na elabora??o de atividades de ensino que utilizam modelos, foram evidenciadas dificuldades, no processo de constru??o do plano, relativas ? estrutura did?tica e ? proposi??o de atividades que contemplassem modelos, embora os licenciandos tenham mobilizado diferentes elementos referentes ao conhecimento pedag?gico do conte?do. Tais constata??es evidenciam a necessidade de que a ag?ncia formadora possa promover mudan?as na forma??o inicial de modo a propiciar, ao longo desse processo, reflex?es, discuss?es e proposi??es de atividades relativas ?s categorias destacadas nesta pesquisa, contribuindo para a constru??o de elementos iniciais referentes ao conhecimento pedag?gico do conte?do que ser?o desenvolvidos no decorrer da doc?ncia, corroborando, dessa forma, para a profissionaliza??o docente

Therefore, some of the skills for the natural sciences learning must be taught consciously, intentionally and in a planned way, as component of a basic competence. Studies of the last twenty years have shown that students and teachers have plenty of difficulties about skills development and, among several, the skill of interpreting Cartesian graphics, essential for the comprehension of Natural Science. In that sense, the development of that type of professional knowledge during the initial education of future Chemistry teachers has become strategic, not only because they need to know how to use it, but also because they need to know how to teach it. This research has as its general objective the organization, development and study of a process of formation of the skill of interpreting Cartesian graphics as part of the teachers professional knowledge. It has been accomplished through a formative experience with six undergraduate students of the Teaching Degree Course of Chemistry of Universidade Federal do Rio Grande do Norte (UFRN Federal University of Rio Grande do Norte), in Brazil. In order to develop that skill, we have used as reference P. Ya. Galperin s Theory of the Stepwise Formation of Mental Actions and Concepts and its following qualitative indicators: action form, degree of generalization, degree of consciousness, degree of independence and degree of solidness. The research, in a qualitative approach, has prioritized as instruments of data collecting the registering of the activities of the undergraduate students, the observation, the questionnaire and the diagnosis tests. At the first moment, a teaching framework has been planned for the development of the skill of interpreting Cartesian graphics based on the presupposed conceptions and steps of Galperin s Theory. At the second moment, the referred framework has been applied and the process of the skill formation has been studied. The results have shown the possibility of develop the skill conscious about the invariant operation system, with a high degree of generalization and internalized the operational invariant in the mental plane. The students have attested the contributions at that type of formative experience. The research reveals the importance of going deeper about the teaching comprehension of the individualities tied to the process of internalization, according to Galperin s Theory, when the update of abilities as part of the teaching professional knowledge is the issue / ? not?ria nas discuss?es da ?rea de Did?tica das Ci?ncias a necessidade de que os estudantes n?o s? aprendam teorias, leis e conceitos, mas que tamb?m desenvolvam habilidades que lhes permitam o agir competente para a cidadania cr?tica. Nessa perspectiva, algumas das habilidades para a aprendizagem das ci?ncias naturais devem ser ensinadas de modo consciente, intencional e planejadas, como componente dessa compet?ncia b?sica. Estudos nos ?ltimos vinte anos t?m mostrado que estudantes e professores t?m diversas dificuldades no desenvolvimento de habilidades, dentre elas, a de interpretar gr?ficos cartesianos, essencial para a compreens?o das Ci?ncias Naturais. Nesse sentido, o desenvolvimento desse conhecimento profissional na forma??o inicial de futuros professores de Qu?mica passa a ser estrat?gico n?o apenas para saber utiliz?-lo, mas para saber ensin?-lo. Esta pesquisa teve como objetivo geral a organiza??o, o desenvolvimento e o estudo de um processo de forma??o da habilidade de interpretar gr?ficos cartesianos como parte do conhecimento profissional docente, a partir de uma experi?ncia formativa com seis estudantes do curso de Licenciatura em Qu?mica da Universidade Federal do Rio Grande do Norte (UFRN). Para o desenvolvimento dessa habilidade, utilizamos como referencial a Teoria da Forma??o por Etapas das A??es Mentais e dos Conceitos de P. Ya. Galperin e seus seguintes indicadores qualitativos: forma da a??o, grau de generaliza??o, grau de consci?ncia, grau de independ?ncia e grau de solidez. A pesquisa, de natureza qualitativa, privilegiou como instrumentos de coleta de dados o registro de atividades dos licenciandos, a observa??o, o question?rio e testes diagn?sticos. No primeiro momento, foi planejado um Sistema Did?tico para o desenvolvimento da habilidade de interpretar gr?ficos cartesianos, com base nos pressupostos e etapas da Teoria de Galperin. No segundo momento, o referido Sistema foi aplicado junto aos licenciandos e o processo de forma??o da habilidade foi desenvolvido. Os resultados mostraram a possibilidade de formar a habilidade com consci?ncia do sistema de opera??es invariante, com alto grau de generaliza??o e internalizada a invariante operacional no plano mental. Os estudantes manifestaram as contribui??es positivas desse tipo de experi?ncia formativa. A pesquisa, por sua vez, revela a import?ncia de se aprofundar na compreens?o did?tica das individualidades no processo de assimila??o, segundo a Teoria de Galperin, quando se trata da atualiza??o de habilidades como parte do conhecimento profissional docente

Perante um p?blico participante constitu?do por 91 estudantes e 4 professores do ensino m?dio, realizamos uma pesquisa-a??o no intento de explorar como compreendem ci?ncia e g?nero assim como a rela??o desses campos. Por meio de dois instrumentos de pesquisa, um question?rio e um roteiro de entrevista semiestruturado, as concep??es desses indiv?duos foram coletadas, tratadas e discutidas mediante uso da an?lise de conte?do. Os resultados indicam que quase todos os estudantes e alguns professores compreendem a ci?ncia numa perspectiva neutra, salvacionista, positivista, em que a figura masculina de cientista como protagonista ? predominante. Partindo desse diagn?stico foi constru?da uma sequ?ncia did?tica para o conte?do ?Lei de Conserva??o das Massas? em que buscou-se evidenciar o car?ter cooperativo da atividade cient?fica, mediante a exposi??o da colabora??o de outros cientistas para o estabelecimento dessa lei.

Based on references and studies dealing with gender relations in science, questions have been raised, researched and discussed in this work, to promote reflections on the possible consequences of distorted and naive visions can cause in science education. In Brazilian educational documents, there are recommendations for addressing the nature of science in high school, present constructivist character, however, which is widespread, both in the discourse of some teachers and in teaching materials is far from what is proposed. It is necessary to promote increased scientific literacy of students - not only understanding and mastery of codes and concepts of science, but the understanding of aspects related to scientific culture. With 91 students and 3 teachers and a high school teacher, we conducted a survey in an attempt to investigate how they understand science and gender as well as the relationship between these fields. Through two research instruments, a questionnaire and a semistructured interview guide, the views of these individuals were collected, treated and discussed by using content analysis. The results indicate that almost all students and some teachers understand science as neutral, Salvationists, positivistic, in which the male figure scientist protagonist is predominant; the students and the teachers, there is no knowledge of women scientists in the history of science; as the reasons for the small number of women in the sciences courses, the public assigns founded justifications mainly in biological determinism and essentialism. Based on this diagnosis, it was built a didactic sequence consisting of 4 classes which sought to highlight the cooperative nature of scientific activity through collaboration exposure of other scientists, including women. For each class has produced a text support making use of the history of science in chemistry education and other areas of the natural sciences. The use of history of science assumes that it can help students to have a more human understanding of scientific culture, enabling discussions and debates relevant to ethics and social relationship. The application of this teaching sequence allowed a better understanding of issues surrounding the nature of science, deconstructing myths that were diagnosed at baseline, as well as allowed the discussion of relevant chemical concepts in this level of education. It is necessary that the school curriculum, through the approach of its contents, provides the training of students for citizenship critically. We need to discuss various social issues such as gender, race, ethnicity, with a view to exploring the diversity, in an attempt to promote new learning.
