Estudo psicossocial das perdas dentárias na terceira idade

The present study seeks to understand tooth loss by investigating the social representations in the daily life of elderly individuals, thus characterizing itself as a comparative and analytic research. It is known that tooth loss is a common occurrence in elderly individuals, interfering at the psychosocial and biological levels, through its functional, esthetical and social implications. The area of oral health in Brazil is lacking studies on this topic, especially with respect to the psychosocial aspects of the elderly. The Theory of Social Representations and the Central Nucleus Theory were selected for theoretical-methodological support. The Free Association of Words Test was used, whose inducing stimulus were the words tooth loss , in which each subject was asked to associate 3 words, to respond to a questionnaire related to socio-economic conditions and containing an investigation of tooth loss, access to odontological services and the need for dental treatment, and to undergo a focus group interview. The study sample consisted of 120 individuals 60 years of age or over, resident in Natal, RN, Brazil and participants of the Live Together to Live Better group of the Basic Health Unit of Felipe Camarão Residential District and Unati (Open University of the Elderly); an interview was performed with 36 subjects. Data analysis was performed by Evoc 2000, SPSS/99, Graph Pad and Alceste softwares. The results demonstrate that the central nucleus of the social representations of tooth loss for the Live Together group emerged from the difficulty in eating categories, showing a relation between physiologic necessity, desire and pleasure from eating, not to mention the pain that resulted from justifying the tooth loss. Besides the central discourses, the following peripheral elements were gathered: difficulty in adapting to the prosthesis, treatment and difficulty in speaking. All of these categories, except the last, also comprised the class themes of the group interview. For the Unati group the central nucleus emerged from the socio-economic difficulties categories, demonstrating a narrow relation between poverty, access to health and education and esthetics, confirming in the discourse of common sense, the association between tooth loss and aging. At the margin of the central discourses was collected the peripheral element difficulty in adapting to the prosthesis, found both in the Live Together and Unati groups, which expresses the resistance of the subject to this new situation and the failure of the rehabilitation treatment in the sense of reviving the memory of their natural teeth. All of these categories also constitute the class themes of the of the group interview. Thus, through the study of the social representations, we can reveal a reality in the perspective of the social subjects, contemplating the multiple facets of the social-cultural reality experienced by these individuals

Representação social do ensinar: a dimensão pedagógica do habitus professoral

Teaching is an activity inherent to the human condition. Historically, from the institutionalization of education, the key role to pursue that activity has been attributed to the teacher, who is required to adapt to the demands of each historical conjuncture. Currently, according to the new paradigmatic requirements, the teacher must possess various skills in order to handle the complex and challenging act of teaching. Assuming the existence of a gap between what the State and the scientific discourse recommend the teacher act upon in the classroom, a decision was made to identify the configuration and structure of social representation in the act of teaching, put forth by elementary school teachers in the public schools of Natal, RN, Brazil. Therefore, the research relied on the theoretical model developed by Domingos Sobrinho (1998, 2000, 2003), which articulates the praxeology of Pierre Bourdieu with the theory of social representations of Serge Moscovici (1978). It was intended to demonstrate how teachers habitus, in its due historical context, directs the construction of social representations in the act of teaching which guides the actions of the teacher, particularly in the classroom context. At the methodological level, the following methods and techniques were used: bibliographic and documentary review in order to identify the scientific discourse on the subject matter and the official parameters of educational regulation and the act of teaching; the Procedure of Multiple Classifications PMC in order to capture the configuration and structure of the representational content in focus, the direct observation of the classroom to identify in actual terms the social representation as "guide to action" as the theory preaches. From the standpoint of the analysis, quantitative data were analysed through Multidimensional Scaling MDS, covering in this study the Multidimensional Scale Analysis MSA and Smallest Space Analysis SSA; and non-parametric statiscal techniques. Additional data of qualitative value had to undergo categorical content analysis. It was then concluded that the teachers investigated guided themselves by social representation, the product of collectively constructed and shared assumptions about the act of teaching, forming a synthesis of different sources of information and knowledge acquirement, involving elements of common sense, religious habitus, pedagogic models considered outdated, the agencies responsible for teacher training and the hegemonic discourse about education today

A docência na educação infantil: representações sociais dos professores cursistas do proinfantil do Estado do Rio Grande do Norte sobre o trabalho docente

The overall objective of this research is to identify and analyze social representations of (the) teachers(the) Ranciere the Initial Training Program for Teachers in Office in Early Childhood Education - PROINFANTIL - UFRN/MEC on the teaching work, seeking to identify their constituent elements and understand the dynamics of your organization. We assume that these teachers work fundamentally, in the institutions of Early Childhood Education, with knowledge of common sense and related cultural inherent to be/do professor in the design of education guardian/giving handouts to ensure the physical integrity of children, causing a rift between the caring and educating. From this general objective, we elected as specific objectives: identify the social, economic and cultural backgrounds of these (the) teachers (sa); identify what is teaching work for them (the) as well as identify which the psychosocial implications driven by RS on teaching work that point to tensions between the training and the exercise teacher as activity profissional.Como theoretical foundation we opted for Social Representations Theory of Moscovici (2003), Jodelet (2001); Specificities of the teaching Work in Early Childhood Education: Kramer (2002; 2006); OliveiraFormosinho (2007); Zilma de Oliveira (2007), Teacher Training: Ramalho, Nunez and Galthier (2003) and Tardif and Lessard (2008), content Analysis: Bardin (2004). As methodological procedure, we chose the Central Nucleus theory, developed by Jean Claude Abric (2000). Contributed to the scope of this objective the 171 teachers (the) that concluded the Proinfantil NBs to participate of TALP with justifications. The corpus arising from evocations around the words suggested by Carlos Chagas Foundation: give classrooms, teacher, pupil and added the word Child Education, were subjected to a treatment with the aid of the EVOC software (2000), identifying the central nucleus. The results indicate the words more evoked and significant: Planning, child care, educating, and play. Indicating that for these (the) teachers (the) the teaching work in Early Childhood Education must have a systematic pedagogical to educate children. These words correspond to the specificity of being/doing teaching in Early Childhood Education. However, the data shows that it is a job with different characteristics of the teaching work in other stages of education

Inércia e Natureza da Ciência no Ensino de Física: uma sequência didática centrada no desenvolvimento histórico do conceito de inércia

During the last decades the area of science education has discussed issues related to the inclusion of the History and Philosophy of Science (HFS) in the practice of science teaching. Among the arguments put forward in favour of this approach, it is pointed out the possible enhancement of scientific content learning and the understanding of the nature of Science (NoS). In spite of such considerations, we still have a very small number of research papers reporting results of practical interventions that utilize the historical approach, moreover, there is a lack of teaching materials in this perspective. Our work has sought to contribute to this area with regard to two aspects: on the one hand, with the production of didactic material, by drawing up texts on the history of inertia for graduate students. On the other hand, we investigate whether the arguments mentioned above in relation to the didactic use of HFS sustain themselves, in a particular context. We developed and applied a didactic sequence, using the texts that we built, to teach the concept of inertia and discuss selected contents of NoS. The didactic sequence was applied in two graduate classes, one from a course of Geophysics (BSc.) and another from the Physics (teaching formation), both from the Federal University of Rio Grande do Norte (UFRN). An initial survey exposed that students, even having approached the concept of inertia in basic education, presented conceptions of common sense regarding the relationship between force and motion. The questionnaire also allowed us to identify the existence of elements of concepts considered inadequate as regards to NoS. At the end of our research, our data indicated a greater number of positive hits on the issues concerning the concept of inertia. Regarding the aspects of NoS, we were able to identify, in a few cases, a move towards a more appropriate understanding, however, certain distortions persisted, highlighting the limitations of the approach used
