Física dos anos iniciais: estudo sobre a queda livre dos corpos através da metodologia da mediação dialética

The model used in Brazilian schools, based on both traditional and progressive education, transmits information without worrying to show the real meaning of things, and without taking into consideration the previous knowledge of the pupil. How to work with the contents of human knowledge in a meaningful way? One alternative way is the Methodology of Dialectical Mediation (MDM), which consists in four steps or pedagogical moments, rescuing, problem posing, systematizing and producing. This theoretical option considers the educational work as a relationship involving teaching, learning and contents, which are taken as independent moments tightly connected to the ongoing work, instead of isolated elements or static terms. The aim of the present work is to clarify the Methodology of Dialectical Mediation and develop a class proposal according to the MDM approach to the problem of the free falling bodies (gravity, material means and shape). To evaluate the methodology, questionnaires were applied after experiments, with the involvement of students at each predominant moment. The results suggested that the MMD, combined with experimental activity, is a tool that enhances the overcoming of immediate knowledge, allowing students to reach a better understanding of the scientific knowledge.

Entre o cinema e a poesia, a memória e a imagem

The aim of this essay is to analyze common aspects between cinema and poetry such as image and memory. Images represent the subject’s perception, whose memory of things and feelings are built artistically (fragmentary sequences, a new idea of time and space, no-narrative style) into the language of cinema and poetry. Homological relations between both languages are put in evidence in this essay in order to bring to discussion those aspects that show the tinny frontiers that separate artistic systems.

Obtenção e caracterização óptica e elétrica de 'La''Ta'O IND.4' e LiTaO Ind.3 puros e dopados com Eu POT.3+

Eletronicalceramics are used in many applications such as: multilayer capacitor, transducer, pyroelectric sensors and electrooptic devices. In recent years there has been a growing demand for eletronicalceramics with better performance and functionality. This demand has accelerated the development of synthesis techniques to produce powders with well-defined particle size, shape and crystallinity. The eletronicalceramics in the form of bulk are determined by their performance characteristics of the powders used and the preparation process. So, physical and chemical properties of powders, such as chemical control of stoichiometry, purity, homogeneity, particle size and shape should be observed when choosing the methods of synthesis. Among the techniques used so far, the polymeric precursor method, also known as Pechini, has been considered ideal for the preparation of nanosized powders. Thus, this research project aims to use the polymeric precursor method to prepare powders of lithium tantalate and lanthanum tantalate, with good chemical stability. In this aspect is proposed to investigate the effects of variation of the concentration of europium about the properties of tantalate because doping with Eu3 + indicates that they may occupy different sites in the crystal structure, as in the case of LiTaO3. Effects of things like occupation sites, stability of phases and formation temperature have been previously investigated by the group, which motivated the formulation of this project. Our proposal aims to introduce the Eu3 + LaTaO4 and LiTaO3 and study the structural and optical properties of the powders obtained by Pechini method, as well as correlate these studies with the electrical properties of the material, mainly the Ironelectricty Hysteresis.

Percepción de estudiantes de odontología sobre educación a distancia

Introduction: distance education is defined as a learning mode in which pedagogical and didactic mediation in teaching and learning processes is characterized by the use of information and communication means and technology by both teachers and students, and the development of educational activities at different settings and technologyand. Objective: evaluate the knowledge obtained by students from the last year of Odontology about distance education and their opinions about the subject. Methods: across-sectional descriptive exploratory study was conducted. Of the total 140 university students, 120 participated in the study. A self-applied questionnaire was developed with questions related to the student, the use of the Internet and distance education. The professional updating alternatives included were graduate courses and subscription to newspapers. Results: 29.2 % of the students use the Internet on a daily basis; only one student stated that he did not use the Internet. Of the students interviewed, 63.34 % did not know any form of distance education. As a consequence, 97.5 % had never taken part in a distance education course and 62.5 % stated that they did not know whether they would. Conclusions: results show that odontology students are prejudiced against nontraditional learning modes, though they use the Internet on a regular basis. Despite the existence of legislation regulating distance education, students are still concerned about its quality and legality.

Necessidades atuais para a educação ambiental: serão possibilidades?

This study had two objectives: to build theoretically the hypothetical landmarks of the environmental crisis and to conjecture new horizons or utopias which can fulfill themselves in the future in search of another being of the man in the world. Therefore, a bibliographic research has been done and, as methodology of analysis, a dialectic critical method has been used to understand the reality in its contradictions and in the totality of the history, through some suggestions, going toward the domain of the state of things which we can verify in the world nowadays. It has been observed that the hypothetical landmarks of the environmental crisis had and have its origins in the Jewish-Christian monotheism, in the exacerbation of the reason as the only way of knowledge and in the process of capitalist accumulation. Therefore, these landmarks, in almost their totality, have historically been built even before the advent of the capitalism. From this point, three suggestions were launched as questions, or so, possibilities, to open a discussion about the construction of another paradigm: Is it necessary another sense of religion? Is it necessary another sense of reason? Is it necessary another sense of sustainable development? Thus, these questions which have been launched, were thought as the current necessities for the environmental education and they implicate in another historical condition to the mankind.

América latina: as coisas para além delas mesmas

If Plato compared the artist's work a reflection of the things, the contemporary art transcends the projection of things beyond themselves by creating unusual pictures, requiring the reader a posture of meanings' digger to establish the signification. Our object is the mestizo, hybrid and heterogeneous Latin America presented by sensitive eyes of art. We chose the route of ambiguous and poetic language of art, selected three works of Brazilian artist Regina Silveira since the last two decades has sought to un/construction of the image from the shadow, reflection, anamorphic projections, which offers unusual images, poetic visual paradoxes. Art as a mirror labyrinth where the reader/viewer as a wanderer without contemporary "gps" to select territories where will step from a map that he will have to build.
