Resumo
Este estudo investigou o uso de atividades práticas investigativas no ensino de Ciências para estudantes da Educação de Jovens e Adultos (EJA) do ensino fundamental. Foram aplicadas duas oficinas em laboratórios escolares: Extração de DNA do morango e a construção de um modelo estrutural de DNA com balinhas de goma, também chamado de DNA comestível. Na metodologia foram organizados planejamentos didáticos de atividades investigativas com abordagens teóricas e práticas experimentais, mobilizando a participação ativa dos estudantes, incluindo, uso de imagens adequadas, vídeos, chuva de ideias e, principalmente, oficinas experimentais e interativas no laboratório de Ciências. Os resultados indicaram que a abordagem investigativa favoreceu o interesse, despertou a curiosidade e proporcionou maior compreensão sobre conceitos complexos como DNA. Os estudantes levantaram curiosidades e questionamentos relevantes sobre genética e hereditariedade. Houve bastante participação dos estudantes e levantamentos apontados acerca do tema DNA. A diversidade de perguntas dos estudantes reforça a importância de atividades investigativas e experimentais para despertar a curiosidade e o interesse no processo de aprendizagem. As atividades investigativas favoreceram a participação ativa e proporcionaram maior compreensão sobre conceitos abstratos como DNA, célula e a síntese de proteínas. Conclui-se que práticas investigativas são eficazes para a EJA, permitindo maior interação e significado na aprendizagem. É importante e necessário que as discussões sobre essas atividades estejam adentrando gradativamente em planejamentos, projetos e práticas pedagógicas de formação básica e superior, capazes de transformar a visão, as ações e produções que envolvem o ensino das Ciências.
This study investigated the use of hands-on investigative activities in teaching Science to students in elementary school in the Youth and Adult Education (EJA) program. Two workshops were held in school laboratories: DNA extraction from strawberries and the construction of a structural model of DNA using gummy bears, also called edible DNA. The methodology included didactic plans for investigative activities with theoretical and practical experimental approaches, encouraging active participation by students, including the use of appropriate images, videos, brainstorming sessions and, mainly, experimental and interactive workshops in the Science laboratory. The results indicated that the investigative approach fostered interest, aroused curiosity and provided greater understanding of complex concepts such as DNA. The students raised curiosities and relevant questions about genetics and heredity. There was considerable student participation and surveys were made about the topic of DNA. The diversity of questions from students reinforces the importance of investigative and experimental activities to arouse curiosity and interest in the learning process. The investigative activities favored active participation and provided greater understanding of abstract concepts such as DNA, cells and protein synthesis. It is concluded that investigative practices are effective for EJA, allowing greater interaction and meaning in learning. It is important and necessary that discussions about these activities gradually enter into planning, projects and pedagogical practices of basic and higher education, capable of transforming the vision, actions and productions that involve the teaching of Sciences.
