Educação integral em tempo integral: Do movimento Todos Pela Educação à rede pública de ensino de Nova Iguaçu

A pesquisa buscou apresentar elementos para a compreensão das proximidades entre a política pública de educação em tempo integral do governo federal o Programa Mais Educação (PME) e os sentidos para educação defendidos pela mobilização de um segmento do empresariado brasileiro, o movimento Todos Pela Educação, que assume um determinado projeto de sociedade. Nesta pesquisa, o movimento Todos Pela Educação é configurado como uma rede de políticas (BALL, 2001; 2005; 2010) que, ao promover ações educacionais e se articular a atores governamentais, tem influenciado os rumos do ensino público nacional e inserido valores característicos da lógica de mercado como gerencialismo e performatividade. A teoria do discurso de Ernesto Laclau (2011, 2013) viabilizou a análise da dinâmica das articulações políticas no intuito de estabelecer hegemonias no campo da educação. Experiências de educação no país associaram a ampliação da jornada escolar à promoção de uma educação integral que, no Brasil, teve grande influência do movimento escolanovista. Associando a qualidade da educação aos níveis de Índice de Desenvolvimento da Educação Básica (IDEB) alcançados pelas escolas, o PME anuncia promover uma educação integral que se mostrou preenchida pelos sentidos defendidos pelo TPE como: a defesa por uma Base Curricular Comum, associação entre o setor público e o privado para a promoção de ações educativas e ampliação do tempo escolar como maior exposição à situações de aprendizagem de conteúdos. A partir de uma experiência premiada e reconhecida nacionalmente pela promoção de uma educação integral, investiguei os sentidos de educação integral assumidos pelos Programas Bairro-Escola, Mais Educação e Escola Viva desenvolvidos em Nova Iguaçu. O trabalho conclui que o modelo de educação em tempo integral implementado no município não favorece a democratização do ensino uma vez que não se estende a todos os alunos da rede e oferece condições desiguais para realização entre as escolas. Além disso, priorizando atividades de reforço escolar, o atendimento das atividades de contraturno está voltado às turmas que serão avaliadas na avaliação nacional Prova Brasil, o que configura a valorização da aprendizagem de conteúdo e aumento de IDEB em detrimento de experiências significativas e ampliadas na educação dos alunos. Nos moldes que se implementa, a realização de atividades a partir da ampliação do tempo escolar embaraça a rotina escolar por não contar com as condições adequadas para sua realização.

Near optimal combination of sensory and motor uncertainty in time during a naturalistic perception-action task.

Most behavioral tasks have time constraints for successful completion, such as catching a ball in flight. Many of these tasks require trading off the time allocated to perception and action, especially when only one of the two is possible at any time. In general, the longer we perceive, the smaller the uncertainty in perceptual estimates. However, a longer perception phase leaves less time for action, which results in less precise movements. Here we examine subjects catching a virtual ball. Critically, as soon as subjects began to move, the ball became invisible. We study how subjects trade-off sensory and movement uncertainty by deciding when to initiate their actions. We formulate this task in a probabilistic framework and show that subjects' decisions when to start moving are statistically near optimal given their individual sensory and motor uncertainties. Moreover, we accurately predict individual subject's task performance. Thus we show that subjects in a natural task are quantitatively aware of how sensory and motor variability depend on time and act so as to minimize overall task variability.

Structure learning in action.

'Learning to learn' phenomena have been widely investigated in cognition, perception and more recently also in action. During concept learning tasks, for example, it has been suggested that characteristic features are abstracted from a set of examples with the consequence that learning of similar tasks is facilitated-a process termed 'learning to learn'. From a computational point of view such an extraction of invariants can be regarded as learning of an underlying structure. Here we review the evidence for structure learning as a 'learning to learn' mechanism, especially in sensorimotor control where the motor system has to adapt to variable environments. We review studies demonstrating that common features of variable environments are extracted during sensorimotor learning and exploited for efficient adaptation in novel tasks. We conclude that structure learning plays a fundamental role in skill learning and may underlie the unsurpassed flexibility and adaptability of the motor system.

National Status and Trends Bioeffects Program: field methods

Environmental quality indicators provide resource managers with information useful to assess coastal condition and scientifically defensible decisions. Since 1984, the National Oceanic and Atmospheric Administration (NOAA), through its National Status and Trends (NS&T) Program, has provided environmental monitoring data on chemical, physical, and biological indicators of coastal environments. The program has two major monitoring components to meet its goals. The Bioeffects Assessments Program evaluates the health of bays, estuaries, and the coastal zone around the nation using the Sediment Quality Triad technique that includes measuring sediment contaminant concentrations, sediment toxicity and benthic community structure. The Mussel Watch Program is responsible for temporal coastal monitoring of contaminant concentrations by quantifying chemicals in bivalve mollusks. The NS&T Program is committed to providing the highest quality data to meet its statutory and scientific responsibilities. Data, metadata and information products are managed within the guidance protocols and standards set forth by NOAA’s Integrated Ocean Observing System (IOOS) and the National Monitoring Network, as recommended by the 2004 Ocean Action Plan. Thus, to meet these data requirements, quality assurance protocols have been an integral part of the NS&T Program since its inception. Documentation of sampling and analytical methods is an essential part of quality assurance practices. A step-by–step summary of the Bioeffects Program’s field standard operation procedures (SOP) are presented in this manual.

Coral health and disease in the Pacific: vision for action

Shallow coral reefs in the IndoPacific contain the highest diversity of marine organisms in the world, with approximately 1500 described species of fish, over 500 species of scleractinian corals, and an estimated 1-10 million organisms yet to be characterized (Reaka-Kudla et al. 1994). These centers of marine biodiversity are facing significant, multiple threats to reef community and habitat structure and function, resulting in local to wide-scale regional damage. Wilkinson (2004) characterized the major pressures as including (1) global climate change, (2) diseases, plagues and invasive species, (3) direct human pressures, (4) poor governance and lack of political will, and (5) international action or inaction. Signs that the natural plasticity of reef ecosystems has been exceeded in many areas from the effects of environmental (e.g., global climate change) and anthropogenic (e.g., land use, pollution) stressors is evidenced by the loss of 20% of the world’s coral reefs (Wilkinson 2004). Predictions are that another 24% (Wilkinson 2006) are under imminent risk of collapse and an additional 26% are under a longer term threat from reduced fitness, disease outbreaks, and increased mortality. These predictions indicate that the current list of approximately 30-40 fatal diseases impacting corals will expand as will the frequency and extent of “coral bleaching” (Waddell 2005; Wilkinson 2004). Disease and corallivore outbreaks, in combination with multiple, concomitant human disturbances are compromising corals and coral reef communities to the point where their ability to rebound from natural disturbances is being lost.
