Developing algebraic and didactical knowledge in pre-service primary teacher education

This study analyzes the contribution of a teaching experiment for the development of prospective primary teachers regarding knowledge of algebra and of algebra teaching as well as their professional identity. The case study of a prospective teachersuggests that an exploratory approach combining content and pedagogy supports this development, especially in the need to propose challenging tasks, to provide opportunity for students’ autonomous work and collective discussions and to be attentive to children’s representations and strategies in order to promote algebraic thinking

Human Rights as a Tool for Sustainable Development

In poor as much as in rich countries there is a fear that environmentally sustainable development might be contradictory to development in general and equitable development in particular. There could be indeed a contradiction between environmental and social sustainability, too much care for the environment eventually leading to forgetting about the people. The purpose of this paper is to explore institutional principles and tools that allow the conciliation between environmental and social sustainability. In this respect we will present human rights based political economy as an institutional tool of this sort. We will show how a human-rights based political economy could at the same time respect ecological sustainability and social equity. One of the reasons for that consists in the fact that within a human-rights based political economy, welfare is not the result of economic growth, as within traditional political economy, but of justice. The main objectives of development will be attained, therefore, not through growth but through redistribution of resources or of access to resources. In this paper more specific aspects will be presented by examining the human right to work and the human right to water. Regarding the human right to work the main aspect which will be stressed is that within a human rights frame full employment becomes disconnected from both growth and labour market deregulation. It will be shown that traditional policies not only do not solve unemployment but are also not environmentally and socially sustainable. The only policy that is not contradictory with either human rights and de-growth is work sharing by decreasing the length of the work day. When properly enforced this policy has, indeed, historically shown to be the only one that has created jobs. Regarding the right to water, the point is that democratic and human rights oriented exploitation and distribution policies of water are both more sustainable and more equitable than those that intend to transform water into a private good as any other and, thus, promote commodification and privatisation of resources. This way of controlling water exploitation and distribution not only may relieve pressure from the resource but also alleviate deprivation of poorer families, conciliating, therefore, environmental and social sustainability.

The Political Economy Of The Human Right To Water

Water being essential to human survival, a political economy directed to satisfying human basic needs, should be especially concerned with the issue of water availability and distribution. Why is there such inequality in its distribution? This inequality represents a serious violation of a human right, as it will be developed in the paper and therefore should not be tolerated. The issue this paper wishes to address concerns the role played by economics in the unequal assertion of every people?s human right to clean water. First of all, what are we talking about when we talk about economics? A rapid overview can identify at least twenty schools of economic thought, from neoclassic to evolutionary, from Marxist to post-Keynesian. If one had to be accurate, a paper on the impact of economics on the human right to water human rights would then have to be divided in at least twenty chapters. The sort of economics we will be referring to in this paper results from a considerably narrower point of view: economics, here, will be mainstream economics, the school of thought which dominates not only within the academia, but also within the political cabinets and the media. More specifically, this paper will examine how mainstream economics discourse can be conflictive with human rights in general and the right to water in particular. First, within mainstream economic analysis satisfying wants implies the use of concepts like prices, supply and demand, or cost and benefit, and therefore, the issue is ability to pay, in other words purchasing power. With rights, on the other hand, the issue is quite different; the heart of the matter here concerns entitlement, the criteria according to which an individual should qualify to enjoy rights, purchasing power being obviously excluded as well as the consequences of the use of such criteria. Therefore it is perfectly admissible for economics to exclude from access to water those that do not have the capability to pay violating the basic principles of human rights. Second, by putting emphasis on the market as the default regulation institution, mainstream economics also hinders the human right to water because on one hand market is inefficient in reaching universal coverage of water supply and on the other hand it is an unaccountable institution and human rights purveyors need by principle to be submitted to democratic control.Human Rights, Right to Water, Economic Theory, Market.

The role of traditional land use systems in the well-being of rural Timor-Leste

Natural ecosystems and traditional land use systems have an important role in the life and well being of the rural population of Timor-Leste. Our objectives are: 1) to analyse the different functions that natural ecosystems and land use systems supply to the rural populations of Timor-Leste, identifying the goods and services produced and their economic value; 2) to relate the services produced by land use patterns with Timor-Leste rural population well being; and 3) to discuss the impacts of the present situation and to foresee changes on the well being of rural Timor-Leste. This paper is based on a multidisciplinary approach incorporating contributions from several fields of knowledge, and uses documentary sources, field observations and interviews. The land use patterns identified in Timor-Leste are: natural and semi-natural ecosystems, subsistence agriculture, sacred, housing, basic infrastructures and industries and services. These land use patterns produce a set of goods and which are essential for the survival and well-being of Timor-Leste rural communities. Key-words: Timor-Leste, natural ecosystems, land, well being, developmen

NEETin with ICT

Science and Technology Advisory Council (STAC) outlines that 49% of EU citizens identified “job creation” and 33% identified “education and skills” as the top priorities for science and technology innovation over the next fifteen years. Both documents justify the needs in Europe for the ICT field especially for the NEET (not in education, employment or training) citizens. On the other hand, Grand Coalition for Digital Jobs (GC4DJ) in Europe identifies: the training and matching digital jobs; certification; innovative learning and teaching; mobility; awareness raising; increasing effectiveness of education; increasing equity and producing positive impact in the economy, as a priority for European countries. NEETin is a project directed to NEET citizens, to be developed by Higher Education Institutions, VET providers and Enterprises in order to help to overcome a social European dimension through lifelong learning. By creating a Joint Vocational Education Training in Digital Competences in a collaboration between VET providers and the Enterprises, widening the access to higher education, in an innovative student-centred learning model to apply in a European level, we aim to contribute to improve the quality of Education. Through this certified JVET, NEET citizens will develop their digital skills and the success of employability of these learners will be enhanced.info:eu-repo/semantics/publishedVersio

The role of traditional land use systems in the well-being of rural Timor-Leste

Natural ecosystems and traditional land use systems have an important role in the life and well being of the rural population of Timor-Leste. The land itself is the support of natural ecosystems and subsistence agriculture of rural populations of East Timor and is the main focus of this research. This paper is part of work in progress. Our research, located in rural Timor-Leste focuses on land tenure, rural family income and the mechanisms that will induce changes in the rules of traditional society organisation. The main objectives of this paper are: 1) to identify the different land use patterns of Timor-Leste; 2) to identify the goods and services produced by them and 3) to relate the services produced by land use patterns with the well-being of Timor-Leste rural population. This paper is based on a multidisciplinary approach incorporating contributions from several fields of knowledge, and uses documentary sources, direct observations made in various periods in the field and interviews conducted in 2003, 2009 and 2010. We identify as the main land use patterns in Timor-Leste the following ones: natural and semi-natural ecosystems, subsistence agriculture, sacred, housing and basic infrastructures and Industries and services. For Timor-Leste rural communities the above land use patterns produce a set of goods and services, which can be classified as supporting, provisioning, regulating and cultural goods and services, and those are essential for their survival and well-being. The conceptual framework used to examine the above mentioned issues is the human rights approach to development within which human rights are considered as means and objectives of development as much as economic purposes.Timor-Leste, land use patterns, ecosystems goods and services, well-being.

THE POLITICAL ECONOMY OF THE HUMAN RIGHT TO WATER

A água é essencial à sobrevivência humana. Uma economia política humanizada, isto é dirigida para a satisfação das necessidades básicas, deve preocupar-se com a questão da disponibilidade e distribuição de água. No que diz respeito à satisfação das necessidades básicas, podemos afirmar que é relativamente fácil e barato fornecer água para todos. Porque razão, então existe uma desigualdade na distribuição? Esta desigualdade representa uma violação séria de um direito humano, como será desenvolvido à frente, e não deverá ser tolerada. Este artigo trata do papel que a economia desempenha no desigual exercício do direito humano de acesso à água potável. Este artigo examina como o discurso da economia dominante pode entrar em conflito com os direitos humanos em geral, e o direito à água em particular. No âmbito da teoria económica dominante, a satisfação de necessidades implica a utilização de conceitos como preço, oferta, procura, custos e benefícios, e por conseguinte a questão é capacidade de pagar ou poder de compra. Com os direitos, o assunto é diferente, sendo a questão principal, o critério de acordo com o qual um indivíduo está habilitado a usufruir dos direitos, não podendo por isso ser utilizado o critério do poder de compra. Para a economia é perfeitamente admissível excluir do acesso à água aqueles que não têm capacidade de pagar, violando princípios básicos dos direitos humanos. A economia dominante ao pôr toda a ênfase no mercado como a instituição reguladora, torna invisível o direito humano à água. Por um lado o mercado é ineficiente em atingir uma cobertura universal de água potável e por outro lado o mercado é uma instituição que não presta contas e a satisfação dos direitos humanos precisa por princípio de ser submetido ao controlo democrático. ---------------------------------------------Water being essential to human survival, a humane political economy, in other words a political economy directed to satisfying human basic needs, should be especially concerned with the issue of water availability and distribution.

MaLaKuLa: stories inside “magical” seashells

MaLaKuLa is an art installation to be discovered by people walking along the beach. It explores familiar nature elements in their natural context to build a poetical digital experience where the nature elements become interfaces for unexpected narratives. In this installation, curious spectators surprised by the sounds of two “magical” sea shells, explore them to find that they are being taken through a journey of mysterious soundscapes: the sounds of Malakula, telling stories of a lost island in the Pacific Ocean. The narrative takes the listener to an imaginary magical place where one hears the call of the spirits of the land and sea
