Relatório de Estágio

O percurso de formação para a docência que teve início com a Licenciatura em Educação Básica e termina agora com a conclusão do Mestrado em Ensino do 1º e 2º ciclos do Ensino Básico culmina com a realização e defesa do presente relatório cujo objetivo é demonstrar, por meio da análise e reflexão, o trabalho realizado pela mestranda no âmbito da sua intervenção educativa em contexto de Prática Educativa Supervisionada (PES). A intervenção educativa foi um percurso onde foram tomadas opções sustentadas e com intenção pedagógica, numa articulação entre a teoria e a prática, com uma postura permanentemente crítica e reflexiva das práticas com o intuito de as melhorar. O percurso desenvolveu-se numa perspetiva investigativa com características de investigação-ação que culminou na realização de um projeto investigativo implementado nos contextos, percecionando-se, deste modo, a importância da necessidade permanente do professor-investigador para que possa investigar as suas práticas educativas, de forma a melhorá-las e transformá-las. A supervisão teve um papel fundamental no decorrer de todo o processo através do acompanhamento por parte dos supervisores institucionais, contanto com o apoio e colaboração dos professores cooperantes e o trabalho colaborativo com o par pedagógico, permitindo melhorar práticas e contribuir para o crescimento pessoal e profissional da mestranda. O relatório de estágio surge, desta forma, como retrato do percurso desenvolvido, que ilustra o início da construção do que é ser professor e espelha um crescimento pessoal e profissional que se vai desenvolver futuramente

Relatório de Estágio

A Prática Educativa Supervisionada representa, sem dúvida, a etapa mais aguardada pelos estudantes que se formam para serem professores, pois este é um momento recheado de expectativas e descobertas da profissionalidade docente. Por conseguinte, o presente relatório de estágio pretende espelhar o percurso evolutivo da mestranda ao longo dessa prática pedagógica. A passagem pelas escolas ficou marcada por uma postura crítica e reflexiva perante as opções pedagógicas tomadas, sendo que estas resultaram sempre de uma articulação entre os quadros teóricos e práticos de cada área disciplinar. A supervisão, processo crucial durante o estágio, é considerada pela professora estagiária como um momento de acompanhamento e orientação da ação educativa por parte dos supervisores institucionais. A par deste processo foi sempre visível um trabalho colaborativo com o par pedagógico e com os professores cooperantes, com o principal objetivo de atingir novos e melhores modos de agir, ancorando-se, assim, nos pilares da metodologia de investigação-ação. O trajeto construído pela formanda é o retrato de uma experiência de desenvolvimento pessoal e profissional, tendo, porém, a convicção de que, apesar de este relatório marcar o término de um ciclo de estudos inicial, há muito mais para aprender e construir.

Um retrato da área de Neurociência e comportamento no Brasil

A neurociência compreende o estudo do controle neural das funções vegetativas, sensoriais e motoras; dos comportamentos de locomoção, reprodução e alimentação; e dos mecanismos da atenção, memória, aprendizagem, emoção, linguagem e comunicação. Tem, portanto, uma importante área de interface com a Psicologia. Dentre seus objetivos, a neurociência busca esclarecer os mecanismos das doenças neurológicas e mentais por meio do estudo do sistema nervoso normal e patológico. Sua evolução no Brasil tem ocorrido desde meados do século passado, e seu desenvolvimento foi incentivado pela criação de sociedades científicas específicas. O presente artigo relata esse desenvolvimento e descreve os principais grupos atuantes na neurociência brasileira.

Neuropsychological Outcome of Ventral Capsular/Ventral Striatal Gamma Capsulotomy for Refractory Obsessive-Compulsive Disorder: A Pilot Study

Five refractory obsessive-compulsive patients were assessed using a neuropsychological battery after a modified gamma knife capsulotomy. The surgical technique was not associated with profound cognitive deficits. The authors found improvements in attention, vocabulary, learning, abstract reasoning, and memory.

Cognition and brain function in schizotypy : a selective review

Schizotypy refers to a set of personality traits thought to reflect the subclinical expression of the signs and symptoms of schizophrenia. Here, we review the cognitive and brain functional profile associated with high questionnaire scores in schizotypy. We discuss empirical evidence from the domains of perception, attention, memory, imagery and representation, language, and motor control. Perceptual deficits occur early and across various modalities. Whilst the neural mechanisms underlying visual impairments may be linked to magnocellular dysfunction, further effects may be seen downstream in higher cognitive functions. Cognitive deficits are observed in inhibitory control, selective and sustained attention, incidental learning and memory. In concordance with the cognitive nature of many of the aberrations of schizotypy, higher levels of schizotypy are associated with enhanced vividness and better performance on tasks of mental rotation. Language deficits seem most pronounced in higher-level processes. Finally, higher levels of schizotypy are associated with reduced performance on oculomotor tasks, resembling the impairments seen in schizophrenia. Some of these deficits are accompanied by reduced brain activation, akin to the pattern of hypoactivations in schizophrenia spectrum individuals. We conclude that schizotypy is a construct with apparent phenomenological overlap with schizophrenia and stable inter-individual differences that covary with performance on a wide range of perceptual, cognitive and motor tasks known to be impaired in schizophrenia. The importance of these findings lies not only in providing a fine-grained neurocognitive characterisation of a personality constellation known to be associated with real-life impairments, but also in generating hypotheses concerning the aetiology of schizophrenia.

Effectiveness of computer training on attentional skills

This paper presents two studies, both examining the efficacy of a computer programme (Captain's Log) in training attentional skills. The population of interest is the traumatically brain injured. Study #1 is a single-case design that offers recommendations for the second, .larger (N=5) inquiry. Study #2 is an eight-week hierarchical treatment programme with a multi-based testing component. Attention, memory, listening comprehension, locus-of-control, self-esteem, visuo-spatial, and general outcome measures are employed within the testing schedule. Results suggest that any improvement was a result of practice effects. With a few single-case exceptions, the participants showed little improvement in the dependent measures.

The status and barriers to the implementation and continuation of the school gardening projects in Germany, Nigeria and the United States of America

In drawing a conclusion for this study, care must be taken in generalizing findings since the population of students and teachers investigated were limited to certain levels in the different schools and countries. This study recognized some complexity of the factors underlying the status of school gardening instruction and activities in Germany, Nigeria and the U.S. as inadequate time for decision-making in the process of gardening, motivation of teachers and students. This was seen as the major impediments that influenced the status of gardening in the three countries. However, these factors were considered to have affected students’ mode of participation in the school gardening projects. This research finding suggests that the promotion and encouragement of students in gardening activities will promote vegetable production and increasing the numbers of practical farmers. Gardening has the potential to create opportunities for learning in an environment where children are able to experience nature first hand and to use the shared experience for communication (Bowker & Tearle, 2007). Therefore, the need for students to be encouraged to participate in gardening programs as the benefit will not only reduce the rate of obesity currently spreading among youths, but will contribute to the improve knowledge on science subjects. To build a network between community, parents and schools, a parent’s community approach should be used as the curriculum. The community approach will tighten the link between schools; community members, parents, teachers and students. This will help facilitate a better gardening projects implementation. Through a close collaboration, teachers and students will be able to identify issues affecting communities and undertake action learning in collaboration with community organizations to assess community needs and plan the implementation strategies as parents are part of the community. The sense of efficacy is a central factor in motivational and learning processes that govern educational improvement, standard and performance on complex tasks of both teachers and students. Dedication and willingness are the major stimulator and achievement of a project. Through a stimulator and provision of incentives and facilities, schools can achieve the best in project development. Teachers and principals should be aware that students are the lever for achieving the set goals in schools. Failure to understand what students need will result in achieving zero result. Therefore, it is advised that schools focus more on how to lure students to work through proper collaboration with the parents and community members. Principals and teachers should identify areas where students need to be corrected, helping them to correct the problem will enable them be committed in the schools’ programs.

Example General Feedback on Routes to Success Portfolios

This document provides example feedback which has been generated following the marking of a class set of portfolios. It is used as a part of the Routes to Success Module, specifically on the section titled Sustaining Success. Students can read the feedback prior to completing the portfolio to alert them to the possible shortfalls which may occur when they undertake this type of task. The feedback is introduced in the context that the task of completing the portfolio is a developmental one, and that students can expect to learn and improve their performance for this type of task as they develop and refine their skills.

Constitutional judges (guarantee of the Constitution and responsibility)

My aim in this paper is to propose a reflection on the position and the importance that the constitutional judge has in the legal systems of contemporary constitutionalism. The figure of the judge responsible of protecting the Constitution is a key institution, without which we cannot understand the laws of constitutional democracies, their current lines of development, and the guarantee of rights and freedoms that constitute the normative core of these systems. Moreover, the reflection on the exercise of the powers of the judge, its scope and its justification is an important part of contemporary legal discussion, still relevant, albeit not exclusively - in the field of legal philosophy. The object of attention of my reflection is the judge who has the power of judicial review, in a scheme of defense of the Constitution, regardless the specific ways of this defense.

A cost-effective methodology applied to videoconference services over hybrid clouds

This paper tackles the optimization of applications in multi-provider hybrid cloud scenarios from an economic point of view. In these scenarios the great majority of solutions offer the automatic allocation of resources on different cloud providers based on their current prices. However our approach is intended to introduce a novel solution by making maximum use of divide and rule. This paper describes a methodology to create cost aware cloud applications that can be broken down into the three most important components in cloud infrastructures: computation, network and storage. A real videoconference system has been modified in order to evaluate this idea with both theoretical and empirical experiments. This system has become a widely used tool in several national and European projects for e-learning and collaboration purposes.

Cognitive Surveillance Architecture for Scenario Understanding

Uno de los mayores retos para la comunidad científica es conseguir que las máquinas posean en un futuro la capacidad del sistema visual y cognitivo humanos, de forma que, por ejemplo, en entornos de video vigilancia, puedan llegar a proporcionar de manera automática una descripción fiable de lo que está ocurriendo en la escena. En la presente tesis, mediante la propuesta de un marco de trabajo de referencia, se discuten y plantean los pasos necesarios para el desarrollo de sistemas más inteligentes capaces de extraer y analizar, a diferentes niveles de abstracción y mediante distintos módulos de procesamiento independientes, la información necesaria para comprender qué está sucediendo en un conjunto amplio de escenarios de distinta naturaleza. Se parte de un análisis de requisitos y se identifican los retos para este tipo de sistemas en la actualidad, lo que constituye en sí mismo los objetivos de esta tesis, contribuyendo así a un modelo de datos basado en el conocimiento que permitirá analizar distintas situaciones en las que personas y vehículos son los actores principales, dejando no obstante la puerta abierta a la adaptación a otros dominios. Así mismo, se estudian los distintos procesos que se pueden lanzar a nivel interno así como la necesidad de integrar mecanismos de realimentación a distintos niveles que permitan al sistema adaptarse mejor a cambios en el entorno. Como resultado, se propone un marco de referencia jerárquico que integra las capacidades de percepción, interpretación y aprendizaje para superar los retos identificados en este ámbito; y así poder desarrollar sistemas de vigilancia más robustos, flexibles e inteligentes, capaces de operar en una variedad de entornos. Resultados experimentales ejecutados sobre distintas muestras de datos (secuencias de vídeo principalmente) demuestran la efectividad del marco de trabajo propuesto respecto a otros propuestos en el pasado. Un primer caso de estudio, permite demostrar la creación de un sistema de monitorización de entornos de parking en exteriores para la detección de vehículos y el análisis de plazas libres de aparcamiento. Un segundo caso de estudio, permite demostrar la flexibilidad del marco de referencia propuesto para adaptarse a los requisitos de un entorno de vigilancia completamente distinto, como es un hogar inteligente donde el análisis automático de actividades de la vida cotidiana centra la atención del estudio. ABSTRACT One of the most ambitious objectives for the Computer Vision and Pattern Recognition research community is that machines can achieve similar capacities to the human's visual and cognitive system, and thus provide a trustworthy description of what is happening in the scene under surveillance. Thus, a number of well-established scenario understanding architectural frameworks to develop applications working on a variety of environments can be found in the literature. In this Thesis, a highly descriptive methodology for the development of scene understanding applications is presented. It consists of a set of formal guidelines to let machines extract and analyse, at different levels of abstraction and by means of independent processing modules that interact with each other, the necessary information to understand a broad set of different real World surveillance scenarios. Taking into account the challenges that working at both low and high levels offer, we contribute with a highly descriptive knowledge-based data model for the analysis of different situations in which people and vehicles are the main actors, leaving the door open for the development of interesting applications in diverse smart domains. Recommendations to let systems achieve high-level behaviour understanding will be also provided. Furthermore, feedback mechanisms are proposed to be integrated in order to let any system to understand better the environment and the logical context around, reducing thus the uncertainty and noise, and increasing its robustness and precision in front of low-level or high-level errors. As a result, a hierarchical cognitive architecture of reference which integrates the necessary perception, interpretation, attention and learning capabilities to overcome main challenges identified in this area of research is proposed; thus allowing to develop more robust, flexible and smart surveillance systems to cope with the different requirements of a variety of environments. Once crucial issues that should be treated explicitly in the design of this kind of systems have been formulated and discussed, experimental results shows the effectiveness of the proposed framework compared with other proposed in the past. Two case studies were implemented to test the capabilities of the framework. The first case study presents how the proposed framework can be used to create intelligent parking monitoring systems. The second case study demonstrates the flexibility of the system to cope with the requirements of a completely different environment, a smart home where activities of daily living are performed. Finally, general conclusions and future work lines to further enhancing the capabilities of the proposed framework are presented.

Managing boundary spanning elements:an introduction

The primary purpose of boundary spanning has been the information exchange between the organization and its task-environment. With complex, global organizational structures and increased emphasis on outsourcing, organizations today are susceptible to degenerate into ‘silos’ and in turn hampering the synergy and efficiency. Boundary spanning research becomes critical to answer some emerging questions in this area. Organization theorists have considered the boundary spanning construct an important one that explains the boundaries of an organization, inter organizational exchanges, dependence and in general, the concept of an organization. The research in this area seems to fall in two broad streams viz., Organization focused, dealing with issues pertaining to organization system, network, learning and collaboration and Individual focused, exploring issues of actors—and their attitudes, behavior—that traverse the boundaries of organization such as sales person, service workers and public servants. This chapter introduces nine interesting research studies presented in the following chapters of the book and attempt to put them in perspective in light of extant literature in the area of boundary spanning theory.
