A dengue como ferramenta de interdisciplinaridade e popularização científica entre estudantes de ensino fundamental

The majority of the population knows their role in dengue control, preventing the accumulation of water in containers as potential breeding sites of Aedes aegypti, the main vector of dengue. Also known chemical control, widely used by the institutions responsible for the control of endemic diseases. On the other hand, unaware that an alternative measure such biological control through a microbial biopesticide, safe, harmless to health and the environment, can be adopted. Thus, this work reported for elementary school students, simply and clearly, the biological control of mosquitoes through bacterial biopesticide produced locally. Moreover, promoted the interdisciplinary teaching of science and mathematics through the data tabulation and charting on interviews conducted by students, about the level of knowledge of the population about dengue and other related variables.

A indeterminação da linguagem e o conceito de atividade no ensino de língua materna

La théorie des opérations prédicatives et énonciatives de A. Culioli ne porte pas en elle une conception prête à l’emploi de l’enseignement des langues. Ce texte se propose de faire le pont entre cette théorie et les questions d’enseignement. Il construit surtout une réflexion sur les concepts d’activité ou de pratique au sein de l’enseignement des langues maternelles en se basant sur l’activité épilinguistique. Nous souhaitons, en outre, mettre en débat la division qui existe dans l’enseignement des langues entre activité physique et activité mentale.

A interdependência da prática docente e a construção da héxis corporal de professores de Educação Física e suas consequências na unidade escolar

This article aims to show the interdependence between teaching practice and the construction of body hexis of Physical Education teachers and its consequences at schools. It can be observed by the social workers that teach it in a elementary school in the city of Araraquara- -SP. It was established, as basic assumption of this issue, that the social construction of body hexis of Physical Education teachers is a process in constant evolution, because it is the result of the life story with interventions from the social context in which the learner lives. The hexis is the dimension that allows the internalization of the consequences of social practices, and also its body exteriorization, through the way of speaking, gesturing, looking, walking, head posture, faces, ways of sitting, to handle instruments, more and more associated with the voice sound of social workers. Children are particularly attentive, in all societies, to these gestures and postures in which they express themselves in their eyes, anything that features an adult. Finally, it understands the importance of the body hexis in the learning process specifically in school physical education. This practice will incite important behavioral changes in their residence within the school and possibly in a higher education.

Introdução à pesquisa com sequências didáticas na formação continuada online de professores de ciências

The integration of research in teaching practices assumes increasing importance and complexity in education. One aspect involved in this issue and poorly investigated is the training of teachers for the development of research linked with their practices. In this context, we present a training for research developed on a distance-learning course in the Science Teaching, which involves the design, implementation and analysis of didactic sequences: the Study Guide to the Initiation of the Term Paper (SGITP). Our research goal is to present a training proposal produced from the results collected from a survey of the literature of the area, and to investigate its application and its results in the teachers' continuing education program. Using data extracted from the production of students and tutors, we concluded that SGITP had a good acceptance among them and it was positively evaluated by teachers, in addition to promoting a greater understanding of research.

Medidas de controle da circulação do livro didático para o ensino de leitura e escrita em São Paulo: atuação da commissão revisora de 1918

In order to contribute to the understanding of the history of the teaching of reading and writing and the history of political movement of textbooks in Sao Paulo, Brazil, we present the results of the analysis of the documents produced by the Review Commission Textbook, established in 1918 by the General Board of Education of São Paulo State. This commission aimed to review which books among the already approved by previous committees, should continue as recommended for use in elementary schools in São Paulo. For this, the commission has prepared various reports, which are representative of the actions of the state government to control the circulation and use of textbooks in elementary schools in the early twentieth century.

Simetria no ensino fundamental através da resolução de problemas: possibilidades para um trabalho em sala de aula

This paper presents an alternative way of working with the theme of symmetry in the elementary school classroom. The proposal is based on qualitative research developed in the Professional Masters degree program in Science and Mathematics Teaching. We conducted field-work consisting of applying a sequence of activities for students in the seventh grade. The sequence was developed from the perspective of mathematics teaching using problem solving, taking into consideration aspects relevant to the study of geometry, such as intuition and visualization. In carrying out the activities, the dialogues between students and teacher were recorded and later transcribed. For data analysis we used the procedures of phenomenology. When interpreting the data, we observed that the teaching of symmetry using problem-solving enhances learning. We also found that, in an investigative environment, students are able to identify properties, argue about the geometric characteristics, and justify their opinions.

A percepção dos alunos sobre a avaliação da aprendizagem no Curso de Graduação em Ciências Biológicas

A avaliação educacional pode ser compreendida como um campo da educação e, portanto, marcado por tensões, contradições, interesses, concepções de mundo, de homem, de sociedade e educação. Para alguns estudiosos desta temática, a avaliação transpõe as salas de aulas assumindo também uma posição central na organização e gestão do trabalho pedagógico e de políticas públicas para a educação, além de tornar-se um excelente instrumento de controle dos sujeitos que se encontram na tessitura do processo educativo. Este trabalho intentou traçar algumas percepções sobre a avaliação da aprendizagem no Curso de Graduação em Ciências Biológicas da Universidade Estadual Paulista Júlio de Mesquita Filho (UNESP) - Campus de Rio Claro, através da ótica dos alunos dos anos finais deste Curso. Nesse sentido, buscou-se desenvolver um estudo qualitativo a partir de entrevistas semiestruturada, objetivando identificar as principais concepções e práticas sobre a avaliação da aprendizagem no curso. Os relatos indicam que a prática avaliativa, na maioria dos casos, vem adquirindo fortemente uma função somativa e classificatória, centralizada na memorização e reprodução de informações, ocorrendo quase sempre de maneira externa ao aluno e focada nos resultados da aprendizagem (produto). Pode-se dizer que a nota tem servido ora para ocultar e manter as relações hierárquicas, ora para selecionar aqueles que vão gozar de um incentivo financeiro para o desenvolvimento de outras experiências acadêmicas, resguardando uma lógica meritocrática e seletiva. De modo geral, a prática avaliativa pouco tem contribuído para a (re)organização do trabalho pedagógico pelo professor e para a superação das dificuldades e incompreensões dos alunos. Ainda que, a maioria das vivências tenha adquirido emoções negativas, as experiências mais marcantes se residem naquelas em que o aluno teve maior envolvimento e...

As atividades de demonstração e a teoria de Vigotski: um motor elétrico de fácil construção e de baixo custo

The experimental demonstration is one of the traditional activities used in the ambit of the Science teaching and of the scientific divulgation. However, this activity has not been fully explored yet in the classroom, because teachers have faced considerable difficulties due to the lack of demonstration equipment. In this work we present the explanation of an easy and low-cost assembly of an electric motor, to be used in Physics classes in High School. In addition, we employed Vigotski’s theory to guide this experimental activity in the classroom.

Uma descrição semiótica da metáfora no ensino de biologia: asserções sobre a célula animal

The main objective of this survey is describing signly the metaphor learning resource, with focus on biology education. Our teorical reference is the peircean semiotics, because it means solid heritage to code surveys implicated at science education, it led us to do an explanation about the main lines about that reference, addressed to researchers and lecturers interested in those reasonings. In the description yearned, another objectives appear: demonstrate diferences between metaphor/analogy and pragmatic analogy; to list metaphors, from cell representation analysis, and argue about principals diferences and probable cognitive consequences between the metaphor event in the visual representation and speech sentences. Therefore we analysed the animal cell of a high school first grade studying book – biology – cell biology – used by São Paulo and another state students. The findings demonstrate the undeniable importance of the metaphor as a learning tool in the biology education, and new findings about that, such as its limits in the concept elaboration, gnosiologic consequences for receptioning, the search needs for propositions– pictures between concept relations – in the science speech construction, and other results.

Alfabetização científica em nível médio e a preparação dos cidadãos para o processo de tomada de decisões

The concept of scientific literacy nowadays is permeated by principles eventually inconsistent. Development of cognitive skills, preparation for continuing studies in higher education, preparation for working life and the strengthening of citizenship are some of the competing goals of science education. In respect of Science, Technology, Society and Environment (STSE) Education, the politics of science should be properly taken into account by science education. This paper examines the concept of scientific literacy in the context of STSE Education and points to why and how physics education in high school curriculum should address topics of energy consumption and production in order to provide the background necessary to assess public policies of science, technology and innovation, in particular the Decennial Plan for Expansion of Energy 2020, subjected to public consultation by the Brazilian Ministry of Mines and Energy in 2011.

Investigação sobre a inclusão do episódio histórico da teoria genotípica de Wilhelm Ludwig Johannsen na formação inicial de professores e pesquisadores

This paper is part of a broader investigation on Epistemology of Biology carried out by a group of researchers from Cascavel/PR. It involves studies and research about biological thought on subjects such as the growing of the concepts of gene, genotype and phenotype. The aim of this research was to gather the undergraduate students of Biological Sciences’ views about the role played by the inclusion of a historical episode in the study group as a trigger for epistemological discussions and didactic reflections. Firstly, the students received Johannsen’s article “The genotype conception of heredity”, published in 1911 in the journal The American Naturalist, in which he proposed the concepts of genotype and phenotype, among other ones. After, there was a discussion held by group about the concepts proposed in the article taking into account the epistemological, historical and didactic aspects. Data collection occurred through the recording of the group discussions and individual interviews. The results suggest that the inclusion of this historical episode, enabled the participants to develop critical thinking through collective reflection on the meaning of biological knowledge in different contexts.

El conflictivo nacimiento de la Universid de São Paulo en la década de 1930

The creation of the University of São Paulo in the early 1930’s brought about arguments in the projects about its organization. The idea was to establish the Polytechnic School of São Paulo as the core of the future institution. However, the option adopted in 1934 allocated this position to the newly created Faculty of Philosophy, Science and Letters. This caused a strong reaction by both former professional schools that were incorporated into the university, above all the Polytechnic School. This article sets out to describe the conflicts between the Polytechnic School and the Faculty of Philosophy, Science and Letters during the tumultuous beginnings of the University of São Paulo.

Educação inclusiva: concepções de professores de ciências com relação à inclusão de alunos com deficiência visual em aulas de astronomia

Despite of intense discussion over recent decades about the inclusion of disabled people and the influence of conception of teachers about that inclusion for the effectuation of it, this work sought to identify conceptions of science teachers regarding the inclusion of students with visual impairment in the classes of astronomy providing basis for future studies.
