Processo de reflexão orientada na formação de professores dos anos iniciais: concepções e práticas sobre o ensino de ciências

Esta investigação, de natureza qualitativa, visou conhecer as concepções e práticas de professores dos anos iniciais sobre o ensino de ciências e promover reflexões sobre tal ensino. O trabalho teve como base o Processo de Reflexão Orientada (PRO), uma estratégia para o desenvolvimento profissional a partir do enfoque de questões da prática docente. As questões de investigação foram: Como professores dos anos iniciais concebem, refletem, planejam e realizam o ensino de Ciências? E como refletem e realizam o ensino de Ciências a partir de um Processo de Reflexão Orientado (PRO)? E, ainda, como, a partir de um Processo de Reflexão Orientado (PRO) para professores dos anos iniciais do Ensino Fundamental avaliam o seu próprio desenvolvimento profissional? Os dados foram obtidos a partir de questionários, entrevistas, planejamentos escritos e de vídeogravações dos encontros e de aulas ministradas. A análise dos dados foi feita a partir da análise de conteúdo. As ideias manifestadas pelas professoras sobre ensino de ciências foram classificadas dentro de uma abordagem oscilando entre cognitivista e sócio-cultural. Seus modelos didáticos revelaram ideias pouco consistentes sobre o processo de ensino e aprendizagem, com pouca coerência em relação a modelos de orientação construtivista. Cada professora propôs uma sequência de ensino visando alcançar graus mais complexos. As sequências foram discutidas, novas reflexões foram realizadas e reelaborações foram propostas. As aulas desenvolvidas evidenciaram um progresso de Lívia com relação à participação dos alunos, com a proposição de uma situação-problema, da consideração das ideias prévias dos alunos, embora apresentasse ainda dificuldade de promover uma discussão orientada, que pudesse favorecer a argumentação dos alunos e a compreensão do fenômeno. Já, nas aulas de Roberta observaram-se atividades que privilegiaram a participação dos alunos. Nas aulas das duas professoras ficaram evidentes a proposição de um problema e a sistematização do conhecimento, a partir da elaboração de sínteses orais e escritas e da apresentação para outras classes. Embora as professoras valorizassem o ensino de ciências e a participação ativa das crianças, havia dificuldades para a realização de aulas de ciências por investigação, pois não consideravam a problematização, a exploração das ideias dos alunos, a sistematização do conhecimento e as explicações científicas. O processo de reflexão orientada (PRO) mostrou ser uma estratégia importante para o desenvolvimento profissional dessas professoras, possibilitando reflexões significativas sobre a própria prática, bem como a tomada de consciência de uma nova sistematização das ações docentes, com vistas a uma atuação mais eficaz para promover o ensino de Ciências por investigação.

Formação inicial de professores de química: o processo de reflexão orientada visando o desenvolvimento de práticas educativas no ensino médio

O Processo de Reflexão Orientada apresenta-se como uma nova proposta formativa, a qual pode contribuir para a formação inicial professores. Nesse processo, o futuro professor, mediado por um professor mais experiente, tem a oportunidade de elaborar e avaliar suas ideias sobre o ensino e a aprendizagem, suas metodologias e suas práticas de ensino, podendo clarificar e confrontar suas teorias pessoais. Neste sentido, este trabalho investigou as contribuições do PRO na atuação pedagógica de licenciandos em Química, visando um ensino por investigação e para a promoção da alfabetização científica no Ensino Médio. Para isso, mediados pela pesquisadora, os três licenciandos participantes da pesquisa elaboraram uma sequência de aulas e a desenvolveram em sala de aula, refletindo sobre suas concepções e práticas durante todo o processo envolvido. Diversas propostas de uma mesma sequência de aulas, sobre um mesmo conteúdo químico, foram elaborados pelos licenciandos, de forma a contemplar uma sequência investigativa e para promoção da AC. A última proposta foi aplicada em sala de aula. Os licenciandos avaliaram e refletiram sobre a sua prática em sala de aula e sobre os planos desenvolvidos, utilizando referenciais teóricos sobre ensino por investigação, AC e exigência cognitiva das questões. Para compreender a evolução dos licenciandos durante o PRO, a pesquisadora analisou os níveis investigativos dos elementos pedagógicos presentes nos planos elaborados e nas aulas ministradas por eles; o nível de AC dos planos e das aulas ministradas, bem como, o nível cognitivo das questões propostas nos planos e nas aulas. O processo reflexivo sobre a prática dos licenciandos é evidenciado por meio de categorias de análise e exemplificadas por trechos das transcrições dos encontros reflexivos realizados entre eles e a pesquisadora. As contribuições do grupo durante o processo também foram avaliadas. Os resultados mostram que os planos desenvolvidos pelos três licenciandos apresentaram evoluções na maioria dos tópicos avaliados, o que pode ser justificado pelas reflexões proporcionadas pelos encontros individuais e em grupo. No entanto, algumas dificuldades foram evidenciadas quanto a proposição da questão problema e de materiais para o levantamento das ideias prévias dos estudantes. A análise das aulas evidencia algumas dificuldades vivenciadas pelos licenciandos durante suas regências, como a sustentação da questão problema, bem como, das interações dialógicas. As reflexões realizadas entre a pesquisadora e os licenciandos, durante os encontros individuais, evidenciam momentos relevantes para a formação inicial, visto que os futuros professores expunham suas concepções, anseios e dilemas. Os encontros reflexivos em grupo também evidenciam contribuições, o que possibilitou ao grupo socializar, confrontar e compartilhar suas ideias e experiências. Esta pesquisa também mostra a importância do papel do mediador, já que a confiança dos licenciandos pela pesquisadora parece ter contribuído para o comprometimento deles durante o processo. Assim, o PRO vivenciado pelos licenciandos parece ter contribuído para eles desenvolverem uma postura crítica com relação à prática docente. Ao elaborar os planejamentos e avaliar suas ações, baseados em referenciais teóricos, puderam construir novas ideias sobre o processo de ensino e de aprendizagem em Química.

Project Success through Effective Decisions: Case Studies on Project Goal Setting, Success Evaluation and Managerial Decision Making

The objective of the thesis is to structure and model the factors that contribute to and can be used in evaluating project success. The purpose of this thesis is to enhance the understanding of three research topics. The goal setting process, success evaluation and decision-making process are studied in the context of a project, business unitand its business environment. To achieve the objective three research questionsare posed. These are 1) how to set measurable project goals, 2) how to evaluateproject success and 3) how to affect project success with managerial decisions.The main theoretical contribution comes from deriving a synthesis of these research topics which have mostly been discussed apart from each other in prior research. The research strategy of the study has features from at least the constructive, nomothetical, and decision-oriented research approaches. This strategy guides the theoretical and empirical part of the study. Relevant concepts and a framework are composed on the basis of the prior research contributions within the problem area. A literature review is used to derive constructs of factors withinthe framework. They are related to project goal setting, success evaluation, and decision making. On the basis of this, the case study method is applied to complement the framework. The empirical data includes one product development program, three construction projects, as well as one organization development, hardware/software, and marketing project in their contexts. In two of the case studiesthe analytic hierarchy process is used to formulate a hierarchical model that returns a numerical evaluation of the degree of project success. It has its origin in the solution idea which in turn has its foundation in the notion of projectsuccess. The achieved results are condensed in the form of a process model thatintegrates project goal setting, success evaluation and decision making. The process of project goal setting is analysed as a part of an open system that includes a project, the business unit and its competitive environment. Four main constructs of factors are suggested. First, the project characteristics and requirements are clarified. The second and the third construct comprise the components of client/market segment attractiveness and sources of competitive advantage. Together they determine the competitive position of a business unit. Fourth, the relevant goals and the situation of a business unit are clarified to stress their contribution to the project goals. Empirical evidence is gained on the exploitation of increased knowledge and on the reaction to changes in the business environment during a project to ensure project success. The relevance of a successful project to a company or a business unit tends to increase the higher the reference level of project goals is set. However, normal performance or sometimes performance below this normal level is intentionally accepted. Success measures make project success quantifiable. There are result-oriented, process-oriented and resource-oriented success measures. The study also links result measurements to enablers that portray the key processes. The success measures can be classified into success domains determining the areas on which success is assessed. Empiricalevidence is gained on six success domains: strategy, project implementation, product, stakeholder relationships, learning situation and company functions. However, some project goals, like safety, can be assessed using success measures that belong to two success domains. For example a safety index is used for assessing occupational safety during a project, which is related to project implementation. Product safety requirements, in turn, are connected to the product characteristics and thus to the product-related success domain. Strategic success measures can be used to weave the project phases together. Empirical evidence on their static nature is gained. In order-oriented projects the project phases are oftencontractually divided into different suppliers or contractors. A project from the supplier's perspective can represent only a part of the ¿whole project¿ viewed from the client's perspective. Therefore static success measures are mostly used within the contractually agreed project scope and duration. Proof is also acquired on the dynamic use of operational success measures. They help to focus on the key issues during each project phase. Furthermore, it is shown that the original success domains and success measures, their weights and target values can change dynamically. New success measures can replace the old ones to correspond better with the emphasis of the particular project phase. This adjustment concentrates on the key decision milestones. As a conclusion, the study suggests a combination of static and dynamic success measures. Their linkage to an incentive system can make the project management proactive, enable fast feedback and enhancethe motivation of the personnel. It is argued that the sequence of effective decisions is closely linked to the dynamic control of project success. According to the used definition, effective decisions aim at adequate decision quality and decision implementation. The findings support that project managers construct and use a chain of key decision milestones to evaluate and affect success during aproject. These milestones can be seen as a part of the business processes. Different managers prioritise the key decision milestones to a varying degree. Divergent managerial perspectives, power, responsibilities and involvement during a project offer some explanation for this. Finally, the study introduces the use ofHard Gate and Soft Gate decision milestones. The managers may use the former milestones to provide decision support on result measurements and ad hoc critical conditions. In the latter milestones they may make intermediate success evaluation also on the basis of other types of success measures, like process and resource measures.

Metabolic disorders in the transition period indicate that the dairy cows' ability to adapt is overstressed

Metabolic disorders are a key problem in the transition period of dairy cows and often appear before the onset of further health problems. They mainly derive from difficulties the animals have in adapting to changes and disturbances occurring both outside and inside the organisms and due to varying gaps between nutrient supply and demand. Adaptation is a functional and target-oriented process involving the whole organism and thus cannot be narrowed down to single factors. Most problems which challenge the organisms can be solved in a number of different ways. To understand the mechanisms of adaptation, the interconnectedness of variables and the nutrient flow within a metabolic network need to be considered. Metabolic disorders indicate an overstressed ability to balance input, partitioning and output variables. Dairy cows will more easily succeed in adapting and in avoiding dysfunctional processes in the transition period when the gap between nutrient and energy demands and their supply is restricted. Dairy farms vary widely in relation to the living conditions of the animals. The complexity of nutritional and metabolic processes Animals 2015, 5 979 and their large variations on various scales contradict any attempts to predict the outcome of animals’ adaptation in a farm specific situation. Any attempts to reduce the prevalence of metabolic disorders and associated production diseases should rely on continuous and comprehensive monitoring with appropriate indicators on the farm level. Furthermore, low levels of disorders and diseases should be seen as a further significant goal which carries weight in addition to productivity goals. In the long run, low disease levels can only be expected when farmers realize that they can gain a competitive advantage over competitors with higher levels of disease.

Influencia de la exploración y el almacenamiento de petróleo y gas natural en la relación de las organizaciones con las comunidades

El presente trabajo pretendía investigar y analizar el funcionamiento del mercado de hidrocarburos y gas natural, en busca de determinar la Influencia de la exploración y el almacenamiento de petróleo y gas natural en la relación de las organizaciones con las comunidades. Teniendo en cuenta el concepto de comunidad a partir del marketing relacional donde la comunidad se refiere a los consumidores y el entorno en el cual están inmersos. En este contexto se definieron los principales actores que participan en la relación comercial, el tipo de relación presente entre ellos y todos los factores que intervienen en desarrollo de esta relación que cada vez es más inestable y de corto plazo. Al finalizar esta investigación se reunió información acerca de las relaciones comerciales en el mercado de hidrocarburos, que servirán de fundamento para investigaciones futuras que permitirán plantear alternativas para sobrellevar la incertidumbre de este mercado y de esa manera lograr desarrollar una relación más confiable y duradera entre las organizaciones y las comunidades que intervienen en el proceso comercial. Debido a que aunque existe gran diversidad estrategias que pueden ser implementadas para mantener una relación estable, estas en la mayor parte de los casos no son utilizadas.

Collabowrighting the hyper(play)text: a postdramatic digital poetics

The aim of this research is to exhibit how literary playtexts can evoke multisensory trends prevalent in 21st century theatre. In order to do so, it explores a range of practical forms and theoretical contexts for creating participatory, site-specific and immersive theatre. With reference to literary theory, specifically to semiotics, reader-response theory, postmodernism and deconstruction, it attempts to revise dramatic theory established by Aristotle’s Poetics. Considering Gertrude Stein’s essay, Plays (1935), and relevant trends in theatre and performance, shaped by space, technology and the everchanging role of the audience member, a postdramatic poetics emerges from which to analyze the plays of Mac Wellman and Suzan-Lori Parks. Distinguishing the two textual lives of a play as the performance playtext and the literary playtext, it examines the conventions of the printed literary playtext, with reference to models of practice that radicalize the play form, including works by Mabou Mines, The Living Theatre and Fiona Templeton. The arguments of this practice-led Ph.D. developed out of direct engagement with the practice project, which explores the multisensory potential of written language when combined with hypermedia. The written thesis traces the development process of a new play, Rumi High, which is presented digitally as a ‘hyper(play)text,’ accessible through the Internet at www.RumiHigh.org. Here, ‘playwrighting’ practice is expanded spatially, collaboratively and textually. Plays are built, designed and crafted with many layers of meaning that explore both linguistic and graphic modes of poetic expression. The hyper(play)text of Rumi High establishes playwrighting practice as curatorial, where performance and literary playtexts are in a reciprocal relationship. This thesis argues that digital writing and reading spaces enable new approaches to expressing the many languages of performance, while expanding the collaborative network that produces the work. It questions how participatory forms of immersive and site-specific theatre can be presented as interactive literary playtexts, which enable the reader to have a multisensory experience. Through a reflection on process and an evaluation of the practice project, this thesis problematizes notions of authorship and text.

A formação do pesquisador na pós-graduação em educação na universidade moderna: valores epistemológicos e ético-políticos

Objetivou-se compreender o horizonte axiológico da Universidade Moderna nas suas repercussões na formação do pesquisador em educação no Programa de Pós-Graduação em Educação (PPGED) da Universidade Federal do Pará (UFPA). O Problema de pesquisa expressa-se em duas interrogações: 1) Quais valores epistemológicos e ético-políticos da Universidade Moderna a UFPA incorpora ao seu ideal formativo? 2) Que valores apresentam se na formação do pesquisador no PPGED? Partiu-se de uma abordagem epistemológica, fundamentada na fenomenologia hermenêutica-existencial, que tomou os dados bibliográficos, as transcrições de entrevistas semi-estruturadas e as notas de campo como textos, em cuja organização lançou-se mão de técnicas de análise de conteúdo. Constatou-se que a ideia de universidade moderna, teve a sua origem na filosofia iluminista, que apesar de consagrar a noção de pesquisa como o seu centro, assentava-se, na verdade, no conceito de formação (Bildung), com inspiração no neo-humanismo. Mais do que o pesquisador stricto sensu, a universidade deve formar o homem que pensa por conta própria, autônomo, crítico e racional e é nisso que se encontra a essência do pesquisar. Pôde-se confirmar a tese proposta de acordo com a qual “O referencial ético-político e epistemológico da universidade moderna, baseado na noção de subjetividade autônoma, livre, consciente e crítica, mantém o seu vigor institucional na constituição do horizonte axiológico da formação na UFPA e no PPGED, em particular, embora esses valores venham sendo modalizados e criticados, em um movimento de autocrítica que é parte constitutiva do sujeito moderno.

STATE-AND-TRANSITION MODELING AND ADAPTIVE MANAGEMENT: TOOLS FOR FUTURE CO-DEVELOPMENT OF MADAGASCAR’S NATURAL RESOURCES AND PEOPLE

Madagascar’s terrestrial and aquatic ecosystems have long supported a unique set of ecological communities, many of whom are endemic to the tropical island. Those same ecosystems have been a source of valuable natural resources to some of the poorest people in the world. Nevertheless, with pride, ingenuity and resourcefulness, the Malagasy people of the southwest coast, being of Vezo identity, subsist with low development fishing techniques aimed at an increasingly threatened host of aquatic seascapes. Mangroves, sea grass bed, and coral reefs of the region are under increased pressure from the general populace for both food provisions and support of economic opportunity. Besides purveyors and extractors, the coastal waters are also subject to a number of natural stressors, including cyclones and invasive, predator species of both flora and fauna. In addition, the aquatic ecosystems of the region are undergoing increased nutrient and sediment runoff due, in part, to Madagascar’s heavy reliance on land for agricultural purposes (Scales, 2011). Moreover, its coastal waters, like so many throughout the world, have been proven to be warming at an alarming rate over the past few decades. In recognizing the intimate interconnectedness of the both the social and ecological systems, conservation organizations have invoked a host of complimentary conservation and social development efforts with the dual aim of preserving or restoring the health of both the coastal ecosystems and the people of the region. This paper provides a way of thinking more holistically about the social-ecological system within a resiliency frame of understanding. Secondly, it applies a platform known as state-and-transition modeling to give form to the process. State-and-transition modeling is an iterative investigation into the physical makeup of a system of study as well as the boundaries and influences on that state, and has been used in restorative ecology for more than a decade. Lastly, that model is sited within an adaptive management scheme that provides a structured, cyclical, objective-oriented process for testing stakeholders cognitive understanding of the ecosystem through a pragmatic implementation and monitoring a host of small-scale interventions developed as part of the adaptive management process. Throughout, evidence of the application of the theories and frameworks are offered, with every effort made to retool conservation-minded development practitioners with a comprehensive strategy for addressing the increasingly fragile social-ecological systems of southwest Madagascar. It is offered, in conclusion, that the seascapes of the region would be an excellent case study worthy of future application of state-and-transition modeling and adaptive management as frameworks for conservation-minded development practitioners whose multiple projects, each with its own objective, have been implemented with a single goal in mind: preserve and protect the state of the supporting environment while providing for the basic needs of the local Malagasy people.

Process oriented framework to support PLM implementation

Product lifecycle management (PLM) innovates as it defines both the product as a central element to aggregate enterprise information and the lifecycle as a new time dimension for information integration and analysis. Because of its potential benefits to shorten innovation lead-times and to reduce costs, PLM has attracted a lot of attention at industry and at research. However, the current PLM implementation stage at most organisations still does not apply the lifecycle management concepts thoroughly. In order to close the existing realisation gap, this article presents a process oriented framework to support effective PLM implementation. The framework central point consists of a set of lifecycle oriented business process reference models which links the necessary fundamental concepts, enterprise knowledge and software solutions to effectively deploy PLM.

CVD of CrO(2): Towards a lower temperature deposition process

The deposition of highly oriented a-axis CrO(2) films onto Al(2)O(3)(0001) by atmospheric pressure (AP)CVD at temperatures as low as 330 C is reported. Deposition rates strongly depend on the substrate temperature, whereas for film surface microstructures the dependence is mainly on film thickness. For the experimental conditions used in this work, CrO(2) growth kinetics are dominated by a surface reaction mechanism with an apparent activation energy of (121.0 +/- 4.3) kJ mol(-1). The magnitude and temperature dependence of the saturation magnetization, up to room temperature, is consistent with bulk measurements.
