This paper aimed to identify and analyze how much of biology is present in science teaching periodicals, and what the theoretical trends of these researches are. Initially, we selected Science Teaching and Education journals that had the term biology teaching in their scope, resulting in nine journals. From these, articles published in 2018, which deal with the teaching of Biology, were selected. The analysis of the theoretical trends of the articles was characterized by descriptors, supported by the state of the art methodology, including privileged content area, school level, and thematic focus of the research. We found a higher prevalence of General Biology research, followed by Environmental Education and the Environment. We also identified a concentration of research in high school and higher education, and thematic focus on the content-method relationship, followed by teacher education. It is noteworthy that works of this nature are indispensable because they allow an overview of the academic production of research in the teaching of Biology, in order to promote the dissemination of scientific research of thematic focuses, as well as verify gaps and new research demands in specific areas, less explored in its teaching and learning process.
The scientific environment is characterized by demands of productivity, fact that leads to discussions and debates about the quality of the produced works. The ethical conditions for the elaboration of scientific articles, such as that involving the real participation of the authors in the productions, have demanded the establishment of precise and clear criteria. In this sense, this study sought to identify and analyze authorship criteria in Qualis Capes A1, A2, and B1 journals in the area of Education, which have in their scope Science Education or Science Teaching, in order to identify the existence of guidelines to the possible authors. From this study, the objective was to discuss authorship criteria to improve the quality and reliability of scientific productions. For this, 44 journals were selected to analyze information about the authorship criteria. It was observed that the ORCID registration requirement for researchers is present in four journals; whereas guidelines on plagiarism are present in 11 journals; whereas only three journals require specific titling of the authors; and 18 journals refer to the authors' contribution criteria in scientific work. These data indicate that most of the journals evaluated present insufficient information to the authors, showing little concern with this part of the article production process. With the above, it is clear that research with journals should continue to be developed, seeking the criteria established by journals to ensure the fairness of the indication of authorship, as these contribute to the quality, ethics and dissemination of research by journals.
In this research we seek to analyze and understand the construction of knowledge about Down Syndrome, based mainly on the work of John Langdon Down and its repercussions in the 19th and early 20th centuries. This research is configured as being descriptive and fits as a study of the history of science, for that we mainly search primary sources and we also resort to secondary and tertiary sources about Down Syndrome. John Langdon Down occupies a prominent role due to significant changes in the panorama of scientific knowledge of the 19th century about Down Syndrome, as he carried out the systematization and description of the syndrome as a unique and differentiated clinical condition, disseminated ideas of care and treatments to individuals, besides contributing to the differentiation in relation to “cretinism” and other mental deficiencies. When developing his reflections, Down subsidized other works of that time contributing to the construction of scientific knowledge about the syndrome. We realized that his notes were corroborated by some and that other researchers contributed to the initial process of building knowledge about Down Syndrome. This work is part of the doctoral thesis work of the first author and will provide subsidies for an upcoming research on the construction of knowledge from the second half of the 20th century, complementing important data on the history of syndrome.
O presente trabalho teve como objetivo a elaboração de uma proposta de sequência didática envolvendo atividades baseadas na resolução de problemas sobre o tema câncer para utilização no Ensino Fundamental, com caráter interdisciplinar das áreas da física, química e biologia. A sequência didática foi elaborada partindo de quatro temas centrais: DNA, Radiações, Protetor solar e Radioatividade. Acreditamos que esse material possa promover um maior interesse dos alunos fazendo com que deixem de ser espectadores e tornem-se sujeitos atuantes no processo de construção do conhecimento. Pretende-se realizar uma validação da sequência didática e desenvolvê-la em sala de aula para indicar além de suas potencialidades e limitações, as implicações da inserção da temática no ensino de ciências.Palavras Chave: Ensino de Ciências. Sequência didática. Resolução de problemas.
