Atividades experimentais no ensino de biologia em escolas públicas do estado do Rio Grande do Norte, Brasil: caracterização geral e concepção de professores

Recent research has revealed that the majority of Biology teachers believe the practice of experimental activities as a didactical means would be the solution for the improvement of the Biology teaching-learning process. There are, however, studies which signal the lack of efficiency in such practice lessons as far as building scientific knowledge is concerned. It is also said that despite the enthusiasm on the teachers‟ part, such classes are rarely taught in high school. Several studies point pedagogical difficulties as well as nonexistence of a minimal infrastructure needed in laboratories as cause of low frequency in experimental activities. The poor teacher performance in terms of planning and development of classes; the large number of students per class; lack of financial stimulus for teachers are other reasons to be taken into account among others, in which can also be included difficulties of epistemological nature. That means an unfavorable eye of the teacher towards experimental activities. Our study aimed to clarify if such scenario is generalized in high schools throughout the state of Rio Grande do Norte Brazil. During our investigation a sample of twenty teaching institutions were used. They were divided in two groups: in the first group, five IFRN- Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte schools. Two of those in Natal, and the other three from the country side. The second group is represented by fifteen state schools belonging to the Natal metropolitan area. The objectives of the research were to label schools concerning laboratory facilities; to identify difficulties pointed by teachers when performing experiment classes, and to become familiar with the conceptions of the teachers in regarding biology experiment classes. To perform such task, a questionnaire was used as instrument of data collecting. It contained multiple choice, essay questions and a semi-structured interview with the assistance of a voice recorder. The data analysis and the in loco observation allowed the conclusion that the federal schools do present better facilities for the practice of experimental activities when compared to state schools. Another aspect pointed is the fact that teachers of federal schools have more time available for planning the experiments; they are also better paid and are given access a career development, which leads to better salaries. All those advantages however, do not show a significantly higher frequency regarding the development of experiments when compared to state school teachers. Both teachers of federal and state schools pointed infra-structure problems such as the availability of reactants, equipments and consumption supplies as main obstacle to the practice of experiments in biology classes. Such fact leads us to conclude that maybe there are other problems not covered by the questionnaire such as poor ability to plan and execute experimental activities. As far as conceptions about experimental activities, it was verified in the majority of the interviewees a inductive-empiric point of view of science possibly inherited during their academic formation and such point of view reflected on the way they plan and execute experiments with students

Uma abordagem dialógica para a utilização de atividades experimentais em sala de aula

The belief of using experimental activities in the teaching of Physics as a strategy to produce a more efficient teaching-learning process is great among teachers and the school community. However, there are many difficulties for their implementation and when it happens they do not contribute for an improvement in class efficiency due to the method used. In this work, we developed a proposal for using these activities in Physics classes in high school, from a critical-reflexive approach in which the constant dialogue between the participants in the teaching-learning process is fundamental. The work was developed in two ways. The first, where the author/writer created an educational material and applied it in classroom and a second one, where he presented the idea to other teachers and undergraduate students from the Physics course at UFRN and IFRN (former CEFET-RN) through an extended workshop entitled "The role of experimental activities in the Physics teaching". This workshop had the duration of 60 hours and was implemented in 4 steps: i) sensitization and formation, ii) material development, iii) material implementation and iv) evaluation by teachers and students from the classes where the material was applied. The goal of this workshop was to present the approach, evaluate how the participants received the idea and how they would apply it in real situations. The results of the application in classroom allowed us to reach some conclusions. This approach was well received by the students as well as by the workshop participants. Despite some difficulties in relation to the handling of the implementation results by the workshop participants, they indicated changes in these professionals teaching practice and the introduction of experimental activities has been an important subsidy to assist them in Physics class in high school

As dificuldades de implantação de atividades experimentais investigativas no ensino de Química

Dissatisfaction with certain aspects of the educational processes of the traditional teaching has always existed, and new teaching methods have been routinely studied. The experimental investigative activity is one of those alternative practices. In this type of activity the experimentation is inserted with an investigative approach, in which the student must build the concept, with proposals that represent solutions to the excited problems. In the teaching of chemistry, specifically, the need and importance of experimentation is evident, beyond motivate students, aid in the understanding of chemical concepts relating them to reality. Realizing the contributions of this methodology for teaching and learning, through this research was conducted to understand the difficulties encountered by teachers for planning and implementation of these activities in the teaching of chemistry and therefore the reasons for the dominance of traditional teaching method. The subjects were undergraduate students of chemistry course that developed and implemented differentiated learning activities for teaching and teachers who accompanied the high school students who participated in the university extension project Inclusion Science and University students and teachers from public: Teaching and Learning Chemistry focuses on research and practice”. Through the data it was possible to identify some factors that affect and hinder the implementation of experimental activities in general, not only the investigative. However, despite the difficulties experienced by undergraduates, the majority considered the activity as an alternative teaching method interesting and innovative, able to produce interest, motivation and participation of students with subsequent learning. As well as the teachers, what with all the difficulties that they had declared facing when applying experimental activities, they admitted the pedagogical...

As atividades experimentais no ensino de física

This work was developed from a literature search in order to provide teachers of physics theoretical and methodological requirements for the use of experimentation in physics teaching, with the aim of contributing to the teaching practice of these teachers and, consequently, for improving teaching this discipline. Therefore, to deal in the course of this research, the goals and types of practical activities, new information and communication technologies that fit the experimental approaches and the role of the teacher in this context, specifying the variables that influence and relate with experimental activities. Studies are presented on the methodology and planning of experimental activities to draw attention to the teacher and the important issues relevant to the preparation of these activities as, for example, the proposed objectives and types of discourse and existing approaches for the conduct of practical activities. In this sense, the trend is highlighted for walks where the approach of practical activities, within the context of practices interactionist and are pointed out strengths and weaknesses of different types of activities presented. We also highlight aspects of the learning process associated with some theoretical reference that are on that subject, as Piaget, Vigotski and Ausubel, so that the teacher can apply the concepts in their theories worked in the practical lessons of physics

O uso de atividades experimentais de demonstração para a aprendizagem de eletromagnetismo

This research aimed to verify if the use of experimental demonstration activities through an approach that employed discursive patterns that provided social interaction in the classroom, provided the students motivation to participate in activities and learn the worked contents. The students of this research were twenty four in a Guaratinguetá's school, aged between 19 and 24 years. The instruments of analysis were transcripts of conversations that occurred between student / teacher and student / student and also the studes s answers to a evaluative questionnaire. In order to support this analysis, we used the Vygotsky Social Historical theory . The results showed that the use of demonstration activities, following an approach that used discursive patterns that enabled the social interaction between teacher and students and among students, motivated students to learn the worked contents

O papel da formação continuada de física na relação de professores com as atividades experimentais

Esta pesquisa investiga dois professores de Física do ensino médio com grande experiência em sala de aula e frequentadores dos cursos de formação continuada da USP ministrado pelo Instituto de Física no período das férias. Estes professores participam ativamente das atividades mensais propostas pelo grupo de trabalho desses cursos e são profissionais de certo modo implicados com seu processo de aprendizagem e formação. Eles foram acompanhados em um curso ministrado durante o período de férias e em reuniões mensais no Instituto de Física da USP de São Paulo. Utilizamos a metodologia da pesquisa qualitativa, coletando os dados a partir de observações destes professores em diversos contextos e de entrevistas semiestruturadas baseadas em suas histórias de vida. Um dos objetivos da pesquisa foi, à luz da psicanálise, utilizando o autor Wilfred Ruprecht Bion como referencial teórico, compreender as relações que os professores estabelecem com as atividades experimentais e como lidam com as frustrações que estas atividades evocam. Compreendendo esta relação, investigamos qual seria o papel da formação continuada nesta relação dos professores com as atividades experimentais. Propusemos uma organização em categorias para descrever as trajetórias destes dois professores, mostrando de um modo geral como eles lidam com as frustrações, ora enfrentando-as, ora fugindo delas. A partir da observação e entrevistas em ambiente de formação continuada, nosso segundo objetivo foi fazer uma reflexão de como os cursos de formação continuada estão atuando para dar suporte ao professor que busca os cursos e que na maioria das vezes está em um estado de dependência ao invés de ter a autonomia pressuposta pelos formadores. Percebemos que os formadores de uma maneira geral não estão servindo de continentes para as frustrações e angústias provenientes das experiências emocionais dos professores que surgem do contato com as atividades experimentais. Desta forma concluímos que devemos repensar os cursos de formação continuada para que possam contemplar as subjetividades do professor.

O experimento e o lúdico: reflexões sobre atividades didáticas experimentais para o ensino de Física e a ludicidade

In this work, is discussed the importance of experimental activities in Education of Physics in Basic Education from the experience of Supervised Stage and the work with the Initiation of Teaching in the Program PIBID CAPES, in this case linked to the Department of Education of the Institute of Biosciences, Campus Rio Claro, São Paulo State, in partnership with three schools of basic education in the city. At first, based on the work of Ferreira with Instrumentation for Teaching Physics, consider the electrostatic theme. The focus is the searching for equipments constructed with low cost materials and easy access. Were developed and promoted strategies of the use of such materials in Physics’ Teaching, with a view to reintroducing experimental teaching activities in Public Basic Education, in the form Workshop Learning and Teaching of Physics, as well as lessons of Laboratory with the help of script and also in the form of an Experiments Library. These experimental activities were critically analyzed with a focus on playfulness. The focus of work in experimental activities for the Physics’ Teaching allowed to redeem, critically, didactic materials. From the standpoint of playfulness, playful moments and interaction of individuals with the knowledge that provides the experimental material when used strategically, they seem to be of great relevance to the Physics’ Teaching in Basic Education. It is possible to use experiments in Physics’ Teaching in public schools

Formação de educadores de infância e professores do 1º ciclo para a prática das ciências experimentais

O Ensino Experimental das Ciências é fundamental para que os cidadãos adquiram conhecimentos, competências, capacidades e valores necessários para viver na sociedade atual. As novas Tecnologias da Informação e Comunicação propiciam uma cidadania participativa, crítica, uma nova forma de aprender e ensinar e também novas conceções de saber. Neste projeto de supervisão clínica conciliou-se a dinamização das Ciências Experimentais com as novas Tecnologias de Informação e Comunicação proporcionando-se assim não só a formação contínua de docentes do Pré-Escolar e do 1º Ciclo do Ensino Básico em exercício, mas também o desenvolvimento de competências nestas duas áreas por parte das crianças envolvidas. Este trabalho baseou-se na metodologia de investigação-ação, foi desenvolvido nos laboratórios de Biologia e de Geologia da Escola Secundária Cacilhas-Tejo, e envolveu uma turma de crianças do Pré-Escolar e uma escola com seis turmas de alunos do 1º Ciclo do Ensino Básico, do 1º ao 4º ano de escolaridade. As atividades experimentais/laboratoriais foram planificadas, avaliadas e feita uma reflexão de modo a adequar objetivos e estratégias. Para a concretização desta investigação foram utilizados vários recursos e para a sua avaliação várias fontes de dados, os quais foram recolhidos em diferentes momentos do desenvolvimento do mesmo. Ao longo deste estudo, que se focou no segundo ano do desenvolvimento do projeto “Experimentar a Brincar”, recolheram-se dados pela observação participante e pelo diário do investigador. No final realizaram-se entrevistas, às docentes que participaram no projeto. Outra fonte de dados utilizada consistiu nos relatórios finais do primeiro e do segundo ano de implementação do projeto. Na avaliação final deste trabalho de investigação-ação concluiu-se que tinham sido melhoradas as práticas de ensino dos docentes do Pré-Escolar e do 1º Ciclo no âmbito das Ciências Experimentais, ocorrendo assim formação contínua, levada a cabo através do trabalho colaborativo, patente no desenvolvimento de vários tipos de competências nas crianças envolvidas.
