This research presents a study concerning the (re) construction of the knowledge of organic chemistry by students in the 3rd stage of Education for Young and Adults (EJA) from a public school. In the search for a meaningful learning it was used the theme The chemistry of teas associated to the teaching methodology Learning Unit (UA), for having structural basis in the previous knowledge and the daily life of the students. In the development of the activities, it was offered to the students an environment favorable for the interaction and socialization of their knowledge through different activities. The data were collected through a questionnaire which aimed to know their previous conceptions; the diagnostic questionnaires which allowed to evaluate the apprenticeship of the concepts of Organic Chemistry seen in theoretical and practical forms by the theme proposed; the class casebook which allowed to testify the process of evolution of the knowledge in the different activities proposed and the final questionnaire which allowed to evaluate the proposal developed. The data were analyzed in an interpretative manner, in a predominantly qualitative approach. Based on these data, it was possible to identify the development and maturation of the knowledge of the students about organic chemistry and especially about these concepts with everyday life. / Este trabalho de pesquisa apresenta um estudo a respeito da (re) construção do conhecimento de química orgânica por estudantes da 3ª etapa da Educação de Jovens e Adultos (EJA) de uma Escola da Rede Pública de ensino. Na busca por uma aprendizagem significativa, utilizou-se a temática A química dos Chás associada a metodologia de ensino Unidade de Aprendizagem(UA), por ter base estrutural no conhecimento prévio e no cotidiano dos estudantes. No desenvolvimento das atividades foi oportunizado aos estudantes um ambiente propicio para a interação e socialização de seus conhecimentos, através de diferentes atividades. Os dados foram coletados através de um questionário inicial, que objetivava conhecer as concepções prévias; os questionários diagnósticos, que permitiram avaliar a aprendizagem dos conceitos de Química Orgânica trabalhados de forma teórica e prática através da temática proposta; o diário de aula, que permitiu constatar os processos de evolução do conhecimento nas diferentes atividades propostas e o questionário final, o qual permitiu avaliar a proposta desenvolvida. Os dados foram analisados de maneira interpretativa, em uma abordagem predominantemente qualitativa. Com base nestes dados, foi possível identificar a evolução e amadurecimento dos conhecimentos dos estudantes com relação a química orgânica e principalmente a relação destes conceitos com cotidiano.

For that, teaching-learning process related to basic chemical subjects which support the understanding of organic chemistry concepts was evaluated in a research period of two years. The education proposal linked to the theoretical content of the cited classes, pointed out the process of knowledge construction, in which educational commitment as well as dedication in the teaching-learning process was also valued. In that approach several didactic tools were applied, among them scientific articles were used as supplementary studies of the basic organic chemistry concepts and related. The acceptability of students, as well as their motivation, performance and learning process was justified by the data collection of the applied teaching methodology. The acceptability and commitment of the students facing this teaching interactive approach, which transversely contributed to the intellectual maturity growth of the students, as well their professional development, were evidenced by satisfactory obtained results that will be herein discussed / O enfoque deste trabalho est? vinculado ao ensino de qu?mica, com abordagem espec?fica para disciplinas de Qu?mica Org?nica ministradas nos cursos presenciais de gradua??o em Engenharia Qu?mica, Farm?cia e Zootecnia da Universidade Federal do Rio Grande do Norte. Para tanto, realizou-se uma pesquisa com dura??o de dois anos consecutivos, objetivando-se a avalia??o do processo ensino e aprendizado referente aos conceitos qu?micos b?sicos que d?o suporte ao entendimento da qu?mica org?nica. A proposta de ensino vinculada aos conte?dos te?ricos dessas disciplinas valorizou o processo de constru??o do conhecimento, que sinaliza para a necessidade de comprometimento educacional no processo ensino e aprendizado. Neste estudo, diversas ferramentas did?ticas foram aplicadas, dentre elas, destaca-se leituras complementares de artigos cient?ficos que abordam assuntos pontuais ou correlatos aos conhecimentos b?sicas de qu?mica org?nica. A proposta para o instrumento de coleta de dados consistiu em avaliar o desempenho e aprendizado dos alunos. De acordo com os resultados obtidos foi poss?vel comprovar que os ?ndices satisfat?rios de aprova??o nas turmas avaliadas, demonstram o comprometimento do aluno diante da metodologia aplicada, que de forma transversal contribui para a forma??o profissional e o amadurecimento intelectual do estudante

Teachers, while teaching, are facing to some sections of schoolwork which make serious problems to understand. The main task of this diploma thesis is solving the issue of organic chemistry on the field of Gymnasium. The pedagogical attitude was chosen for the selection of problem parts. New educational materials were purposed on the basis of gathered information and thanks to the research the efficiency of teaching the organic chemistry and its problematic parts should augment the undestanding of the problematic parts as well as the bettering of education. Theoretical part of the diploma thesis looks into the methodology of pedagogical research, curriculum documents, didactic methods and forms and literature exploration of defined problem parts of textbooks of organic chemisty for the high schools. Consequently, the practical part exposes results of the performed pedagogical research and the analyse of schoolbooks. Including noticed facts, the main output of the dissertation is the package of the new educational materials and various methods of education focused on the specific parts of the curriculum of organic chemistry, specificaly the set of the new instructional backgrounds solving the circumstances of organical chemistry. These educational materials and the proposed methods of education were also...
