Aprendizagem significativa e supervisão: estudo exploratório de caracterização de um processo de mudança de práticas de um professor

Neste estudo aborda-se, de forma descritiva, o processo de mudança de práticas de um professor do ensino secundário, decorrente de uma relação de supervisão gerida pelo investigador. Essa mudança foi no sentido de um processo de ensino informado pela perspectiva construtivista, mais concretamente pela concepção de aprendizagem significativa tal como perspectivada por Ausubel. A elaboração do estudo envolveu várias fases que incluem a formação, a recolha e a análise de dados, a supervisão. A recolha de dados foi feita, por um lado, através de quatro inquéritos, dois para os alunos e dois para o professor, aplicados em dois momentos distintos: antes da mudança do processo de ensino/aprendizagem e após essa mudança e, por outro lado, através da gravação dos relatos do professor durante o processo de mudança. Antes do bloco de aulas relativo ao processo de mudança, professor e supervisor (investigador) abordaram conjuntamente a perspectiva construtivista e a aprendizagem significativa, e planificaram, também juntos, o bloco de aulas. O processo de supervisão foi enquadrado pelo modelo reflexivo. Os dados (dos inquéritos e das gravações) foram sujeitos a análise de conteúdo, tal como perspectivada por Bardin (1979). Verifica-se a existência de mudanças efectivas relacionadas com a melhoria da preparação das aulas, que tornou o professor mais reflexivo, e com a melhoria da relação pedagógica, que proporcionou aos alunos um papel mais activo no processo de ensino e aprendizagem. Conclui-se sobre a pertinência de repensar a formação contínua dos professores, de forma a incluir supervisores nas escolas que acompanhem os professores no sentido de melhorarem as suas práticas.

Mudança dos processos de negócios e adequação da TI nas empresas em decorrência da implantação do sistema público de escrituração digital SPED: um estudo de casos múltiplos

Companies have always been organized by processes, often imperceptible to its employees. With the advancement of technology, organizational processes currently run an organization through computers, and thus generate immediate information that is available to each sector. With the objective of seeking business information in real time, the government created the SPED - Public System of Digital, which involves three subsystems, which are the Electronic Invoice, Digital Accounting Bookkeeping and Digital Tax Bookkeeping. This system is revolutionizing the business structures when gathering, in an innovative way, all information and interlinked business processes. For the implementation of SPED, a revision in the organizational processes is required, since the information is generated and is sent online to the government, without mistakes. Thus the study aimed to analyze the change brought about by the implementation of the Public System of Digital SPED in the main business processes. In order to do so, we have performed a multiple case study involving three companies in the state of Para, two operate in wholesale and one explores agribusiness. The Data collection was performed by accounting professionals, IT and managers. According to the results obtained, it was found that in two companies, the IT infrastructure was capable of deploying the new system without major problems, while one company had more difficulties to cope with the new system. However, all companies had to examine its processes to make the customizations needed to fit. It was also observed that there is no IT Governance in two companies. Therefore, we recommend the use of an appropriate model, not only for the implementation of SPED, but as a way to manage and extract better results from investment in information technology

Vivendo do mar: tradição, memória e mudança na vida pesqueira de Pitangui-RN

This research focuses on the fishery activity, aligned to knowledge of past generations, and the transformation to those who depend on this activity for their livelihood, at the seashore community of Pitangui in Extremoz municipality, which lies 40 km away from Natal, seat of the state of Rio Grande do Norte. The intense modernization which has taking place during the last few years may be considered the result of a number of economic, social and cultural factors, as the introduction of new fishery technology. On the other hand, the present study seeks to show how this changing process happened, and to what extent those affected understand and evaluate this transformation. The methodology to carry out the ethnographic work was mainly adopted by qualitative methods and techniques - by participant observation, oral history, photography and the audiovisual records besides reference to data extracted under quantitative methods, as an important instrument of analyses. This induces a conclusion that the transformation of the community is a consequence of the globalized market, though still tied up to specific local relations. The emerging results are: the use of new fishery technology, and new ways of orientation and navigation; the opening to new jobs and occupational activity, the re-order of space s appropriation; changing sociability, larger access to consumer goods, besides bringing on some new conflicts land appropriation and the fishery and the protection of the environment. All this comprehended as a result of the movement of the local relations participating in the global spaces

Saúde da família: uma estratégia de mudança no processo de produção dos serviços de saúde

The purpose of this study is to analyze, from the point of view of nurses, changes that took place in the process of providing health services after the introduction of the Family Health Program (FHP). It is na investigation of qualitative nature that uses semi-structured interviews as a main empirical approach tool. Six nurses from the city of Caicó, Rio Grande do Norte, who were working with basic care before the introduction of the FHP, within basic care, were: adscription and ties with the community; hospitality and the humanizacion of care-giving; decrease in cases of inpatient treatment; strengthening of the prevention of injuries and health promotion; improvemente of health indicatiors, finally, actions that point towads meeting the principles of wholeness, equity and universality as a declaration of the Brazilian National Health Care System (SUS). Nevertheless, in spite of all recognizable positive aspects, the FHP has some weaknesses, such as: the difficulty posed by colletive work; the mismatch between professional education and the demands of the current health standard; a poor physical infrastructure of the Basic Health Units; a high heath staff turnover and precarious work conditions. In addition to this, some strategies that can be used to help improve the process of providing health services have been pointed out, such as, coordination between sectors, continuous education, making work conditions less precarious and improving the means whereby heathy service management is conveyed,Tthus, finally, we understand that the FHP does bring forward meaningful changes to the process of provinding health services to strengthen the Brasilian National Health Care System (SUS), in spite of the fact that it lies within a scenario of adversities that can be overcome through the collective endeavor of the several social actors

Ações de profissionais relativas ao banco de leite humano : uma perspectiva de mudança

This is an exploratory and descriptive study that aimed to investigate the actions of professionals in the context of breastfeeding, on the assumption that the actions taken by employees working together to postpartum and newborn are not competing to effect the distribution of pasteurized human milk so that it meets the needs of infants who depend on it. Thus, the study aimed to analyze the actions of medical and nursing staff of the distribution of pasteurized human milk to the newly born. The investigation was developed by action research in a federal hospital, located in the capital the state of Rio Grande do Norte, Brazil, reference assistance to women during pregnancy, childbirth and postpartum high risk in 2010. Study participants were fifty-five professionals chosen from the following inclusion criteria: to act in the NICU or rooming, being a pediatrician and / or neonatologists, nurses and technical nursing. According to the methodology of action research a questionnaire was applied, techniques in focus groups and courses were developed, and, finally, action evaluation. The project was submitted to the Ethics Committee at the Federal University of Rio Grande do Norte and approved with no protocol 448/2009. The problems identified in the responses issued by the social research were grouped into categories according to the similarity between them. The answer to the question of the survey - How is the need for pasteurized human milk for the newborns in neonatal intensive care unit and rooming identified? - Brought subsidies for action planning and implementation of strategies for change in the practice of professionals working in rooming and ICU. Thus, the study has relevance in social care and, when at the local level, will compete for the distribution pasteurized human milk to take effect as best as possible, as recommended by the Ministry of Health. It is also conceived that, in a macro view of society, it could contribute to minimizing the health problem that involves the child population

Trendtv : uma arquitetura para mudança automática de canais de TV baseada em redes sociais virtuais com graus de amizade e suporte a múltiplos dispositivos no cenário da TV digital brasileira

Due to the large amount of television content, which emerged from the Digital TV, viewers are facing a new challenge, how to find interesting content intuitively and efficiently. The Personalized Electronic Programming Guides (pEPG) arise as an answer to this complex challenge. We propose TrendTV a layered architecture that allows the formation of social networks among viewers of Interactive Digital TV based on online microblogging. Associated with a pEPG, this social network allows the viewer to perform content filtering on a particular subject from the indications made by other viewers of his network. Allowing the viewer to create his own indications for a particular content when it is displayed, or to analyze the importance of a particular program online, based on these indications. This allows any user to perform filtering on content and generate or exchange information with other users in a flexible and transparent way, using several different devices (TVs, Smartphones, Tablets or PCs). Moreover, this architecture defines a mechanism to perform the automatic exchange of channels based on the best program that is showing at the moment, suggesting new components to be added to the middleware of the Brazilian Digital TV System (Ginga). The result is a constructed and dynamic database containing the classification of several TV programs as well as an application to automatically switch to the best channel of the moment

Números complexos: uma proposta de mudança metodológica para uma aprendizagem significativa no ensino médio

This work presents a proposal of a methodological change to the teaching and learning of the complex numbers in the Secondary education. It is based on the inquiries and difficulties of students detected in the classrooms about the teaching of complex numbers and a questioning of the context of the mathematics teaching - that is the reason of the inquiry of this dissertation. In the searching for an efficient learning and placing the work as a research, it is presented a historical reflection of the evolution of the concept of complex numbers pointing out their more relevant focuses, such as: symbolic, numeric, geometrical and algebraic ones. Then, it shows the description of the ways of the research based on the methodology of the didactic engineering. This one is developed from the utilization of its four stages, where in the preliminary analysis stage, two data surveys are presented: the first one is concerning with the way of presenting the contents of the complex numbers in math textbooks, and the second one is concerning to the interview carried out with High school teachers who work with complex numbers in the practice of their professions. At first, in the analysis stage, it is presented the prepared and organized material to be used in the following stage. In the experimentation one, it is presented the carrying out process that was made with the second year High school students in the Centro Federal de Educação tecnológica do Rio Grande do Norte CEFET-RN. At the end, it presents, in the subsequent and validation stages, the revelation of the obtained results from the observations made in classrooms in the carrying out of the didactic sequence, the students talking and the data collection

Variação, mudança e ensino: o caso dos pronomes possessivos da gente e nosso(a)(s) em uma abordagem sociofuncionalista

In this work, we analyze the variation and change phenomenon involving the possessive pronouns da gente and nosso(a)(s) in the light of the theoretical referentials of the North-american linguistic functionalism and of the variationist sociolinguistics. At first we present the phenomenon itself, highlighting the fact that few studies have considered it as an object, gap which we will try to fill in with our contribution. In the following chapter, we emphasize concepts and principles of the functionalism and the sociolinguistics that are used as our background for the data analysis. In the third chapter, we present what the normative grammars inform about our object of study, besides synthesizing some works on variation and change involving the personal pronouns nós and a gente. In the following chapter, we analyze the data. We used data from the Discurso & Gramática a língua falada e escrita na cidade do Natal (FURTADO DA CUNHA, 1998) corpus. In this chapter we present the results for the groups of social and linguistic factors which we can control. Grounded on these results, we specify the preferential contexts for employing the pronouns da gente and nosso(a)(s) and we observe that the social motivations, the valorization credited to the forms and the identity marks underly the restrictions exercised in their use by social factor groups, besides obtaining signs of ongoing changes in apparent time (from the age factor groups) and possible use specializations of each form, what helped us verify the course of the grammaticalization process of the referred pronouns in the community of Natal. In the sixth chapter, we make some considerations on the teaching of grammar and propose activities which can be carried on in the classroom involving the possessive pronouns da gente and nosso(a)(s) considering the variation and change issue

Vozes sociais e dimensão ética da lingüística aplicada: a construção discursiva da área nos CBLAs

This research deals with Applied Linguistics and its structure as a scientific field, in compliance with knowledge produced within the range of the Brazilian Congresses of Applied Linguistics (CBLA). The purpose of this research is to understand the meanings disclosed by the voices that make up the scientific discourse on this field, pointing toward its course of development, the ethical position that is peculiar to it and how this position is represented in its scientific practice. The scientific discourse typical of the production of knowledge of Applied Linguistics is now construed as leading to practices that define the production of this field of learning whose object is to study man and man s relationship to language. Theoretical groundwork is anchored on the work the Social Sciences have developed on the paradigmatic crises of science and the social changes resulting from modern and post-modern times, on Applied Linguistics researches on the identity of the field of study, its courses and ethics, and on the bakhtinian theory that supports a view of language as a social practice built under the aegis of the subject s ethics and responsibility. The corpus of this work comprises qualitative and quantitative data made into articles presented at the CBLA. The research methodology conforms to the interpretive paradigm and has the concept of social voices as its category of analysis. Results point towards the progress of Applied Linguistics that, from its role as a mediator discipline between linguistic theory and practical applications, is assuming a position in a field of study of its own, independent, with transdisciplinary characteristics, pursuing through its quests and redefinitions to get closer to the dimension of life and assuming the ethical position of taking on responsibility for its doings and sayings

O latim, uma língua morta?: uma metáfora em análise: o olhar da lingüística aplicada e suas implicações para o ensino

The focus of this research is the teaching of the Latin language. Due to the fact that its teaching has been facing a growing crisis in the last four decades, which currently persists, we ponder about external and internal causes of its decline, aiming at pointing out an alternative that enable us to find a way out of this situation. So, our research questions mainly concern how the teaching of Latin is viewed amongst the academic society, also investigating if it has kept up with the development of the scientific reflection about human language and the new approaches on language teaching. Furthermore, we analyse the contribution that the study of Latin can provide to the academic formation of language teachers and try to identify the areas of knowledge that can contribute to a reshaping of its teaching. Based on these guidelines, we have established as the goals of this research: 1) to reflect about the current situation of the teaching of Latin and the causes of its decline; 2) to determine its social representation among teachers and students of the Language Courses, as a way of defining the role it fulfills in the academic formation of teachers; 3) to accomplish an exploratory study of some handbooks that show alternative proposals on how to teach Latin, in order to detect their adequacy to current times and to the goals of the academic study of languages; 4) to offer an alternative proposal on how to teach Latin that takes into account the principles of Applied Linguistics, considering the socio-historical and cultural aspects of the language, enabling it to meet the requirements set by modern times. This research is divided into two parts. The first part presents the theoretical framework. We map the studies about Latin teaching inside and outside Brazil and argue against the concept of Latin being a dead language, presenting arguments set on changing this view. Then we describe and comment the notions of literacy, genre and culture, which helped us understand the reasons for the decline of the teaching of Latin and to point out suitable ways to overcome the crisis. The second part is dedicated to reflecting on the literacy practices in Latin teaching. We began by examining the answers to the questionnaires given to students and teachers about the view of Latin in the Language Courses; then we reflect on the teaching-learning of Latin as an academic literacy practice followed by an analysis of the didactic material used in teaching Latin. Finally, we suggest an approach of the familiar letter genre in ancient Rome as a means of teaching Latin in a contextualized way

As construções adverbiais em mente: análise funcionalista e implicações para o ensino de língua materna

This research aims at investigating the constructions with adverbials in ly, based on the view of contemporaneous linguistic functionalism, such as proposed by Givón, Hopper, Thompson, Traugott, Furtado da Cunha, as well as the cognitivist notion of language, through construction grammar support upon the patterns of Goldberg and the prototypes theory. The cognitive functional approach adopted here considers the change as a proper and inherent phenomenon of language and understands the linguistic phenomenon as resulting from effective use of language. Another aspect to be considered to the realization of this study is the fact that the formation adjective + ly is a word construction mechanism really productive, which generates interests on linguistic description. In a particular way, our leading objective is to exam the constructions with adverbials in ly in the context of language in use, in its oral and written forms, looking for to apprehend the meaning multiple manifestations forged in the use. Bearing this in mind, we worked with data from the Corpus Discurso & Gramática (Natal). There are, in the data, adverbs ended in ly that take the signification of mode, as foreseen in traditional models, but there are also other significations, for instance, the modalizador in its different manifestations. The results show that this adverb is a linguistic mark that carries in its constitution the multissêmico and multifunctional character, which interferes extremely in the ordination of this category, assuming a position sometimes pre-verbal, sometimes post-verbal. Other aspect observed refers to the relationship between the adverb and the verb, with emphasis on the compatibility or restriction between them, option which is related to the semantic aspect. The data in analysis legitimate the use in different constructions with adverb ended in ly in various genres, as follows: personal experience narrative, retold narrative, local description, proceeding account, opinion account, both in oral as in written language

Vestígios de permanência e mudança dos classificados do Jornal Tribuna do Norte (1951-2010)

The text, to be held in different linguistic spheres, in many aspects absorbs the changing processes through which language passes as a result of socio-historical changes. In this sense, this research proposes a study on gender sorted, motivated by the desire of understanding how the text incorporates traces of change and how to keep its constituents over time, in order to point out what are its characteristic traits. Our analysis is centered on the newspaper s section called classificados of Tribuna do Norte, state of Rio Grande do Norte, between the XX and XXI centuries. From the survey data a descriptive and analytical analysis was performed with a corpus of 250 listings, divided between the years 1951-2010. Based on a diachronic analysis, we also seek to investigate the macro-structural aspects of gender and microstructural compositional elements from the opportunities section that originated the Caderno de Classificados . For this reason, this approach has focused on particular Roman German Philology, especially in the works of Coseriu (1980) and Kabatek (2006). The analysis revealed that since its inception in Brazil, the classificados have fixed constituent elements, such as the use of "sell" and "rent" in the title or introduction, but also shows traces of change in the closure of the text, and especially with regard to the division of classificados by area of interest, that in the newspaper called Tribuna do Norte started in the Opportunities section

Squid impact analyser: uma ferramenta para análise de impacto de mudança em linhas de produto de software

Software Products Lines (SPL) is a software engineering approach to developing software system families that share common features and differ in other features according to the requested software systems. The adoption of the SPL approach can promote several benefits such as cost reduction, product quality, productivity, and time to market. On the other hand, the SPL approach brings new challenges to the software evolution that must be considered. Recent research work has explored and proposed automated approaches based on code analysis and traceability techniques for change impact analysis in the context of SPL development. There are existing limitations concerning these approaches such as the customization of the analysis functionalities to address different strategies for change impact analysis, and the change impact analysis of fine-grained variability. This dissertation proposes a change impact analysis tool for SPL development, called Squid Impact Analyzer. The tool allows the implementation of change impact analysis based on information from variability modeling, mapping of variability to code assets, and existing dependency relationships between code assets. An assessment of the tool is conducted through an experiment that compare the change impact analysis results provided by the tool with real changes applied to several evolution releases from a SPL for media management in mobile devices
