    Despite substantial national effort to integrate technology in education, it seems that practitioners in the education system are not working in line with the given policy. Evidence from large-scale studies of students’ technology practices at school over the last decade show disparities in student practices. The observed gap between the micro and the macro level call for a closer exploration. Research that explores the influence of social and organizational factors may be useful for understanding the processes behind such gaps. Argyris and Schön’s ‘Theory of Action’ (1978) is proposed as an example of an organizational theory that can be adopted in educational technology research to move towards understanding the complexities of technology practice. To encourage discourse and application of Argyris and Schön’s theory in the field of educational technology research, this paper introduces the theory, a review of its empirical application in research of teacher educations’ technology practice and relevant conceptual work. The paper presents a conceptual framework based on Argyris and Schön’s theory that has been developed through two recent studies, and invites its application in future research and development

    SĂŁo raros os estudos envolvendo o uso mĂșltiplo de recursos naturais por populaçÔes amazĂŽnicas. Este trabalho apresenta um panorama de como os Ă­ndios Deni, habitantes da regiĂŁo de interflĂșvio entre dois dos maiores afluentes de ĂĄgua branca da bacia amazĂŽnica, os rios JuruĂĄ e Purus, utilizam dos recursos disponĂ­veis em seu territĂłrio. Os Deni sĂŁo, atualmente, Ă­ndios que vivem da exploração de recursos da terra firme e de regiĂ”es alagadas. SĂŁo um misto de horticultores e caçadores/coletores, que utilizam toda a sua ĂĄrea para a obtenção de recursos para subsistĂȘncia. Como regra, deslocam periodicamente seus assentamentos, evitando o esgotamento local de recursos, e provocando a modificação local do ambiente. Esta alteração aumenta temporariamente a disponibilidade de alimento. Áreas com aldeias, pomares e roçados abandonados, por sua vez, tornam-se locais onde se concentram inĂșmeros recursos da flora e da fauna, posteriormente explorados. O impacto provocado por este sistema Ă© aparentemente mĂ­nimo. Os Deni estĂŁo contextualizados na periferia de um sistema capitalista, onde a Ășnica fonte de renda para adquirir bens que sĂŁo hoje considerados pelos Ă­ndios como indispensĂĄveis para sua sobrevivĂȘncia sĂŁo os recursos naturais. Estes sĂŁo e continuarĂŁo sendo explorados de maneira a produzir um excedente a ser comercializado para a obtenção de uma sĂ©rie de produtos industrializados, independentemente das opiniĂ”es externas. É sobre este patamar que devemos avaliar a sustentabilidade do atual manejo da ĂĄrea.<br>Studies concerning the use of multiple natural resources by Amazonian indians are scarce. This work presents a portrait of how the Deni Indians, inhabitants of an area between two of the most important white-water rivers of the Amazon basin (JuruĂĄ and Purus Rivers), exploit natural resources in their territory. The Deni exploit both the upland and floodplain forests. They are a mix of horticulturalists and hunter-gatherers, using their whole territory to obtain what they need to live. As a rule, they move their settlements periodically, avoiding local resource depletion. The Deni modify the landscape at a local level, causing an increase in resource availability. Abandoned villages, fruit orchards and crops are places where floristic and faunistic resources concentrate and are systematically exploited. The impacts of such management are apparently minimal. For the Deni society natural resources are the only way to get goods for survival, but it is inserted in the periphery of a capitalist system which exploits and will continue to exploit natural resources in order to produce a surplus for the acquisition of industrialized products, independently of external judgements. This should be the starting point to evaluate sustainability in this local management system
