Explaining is one of the most important everyday practices in science education. In this article, we examine how scientific explanations could serve as cultural tools for members of a group of pre-service physics teachers. Specifically, we aim at their use of explanations about forces of inertia in non-inertial frames of reference. A basic assumption of our study is that explanatory tools shape the ways we think and speak about the world. Drawing on the theory of mediated action, analysis illustrates three major claims on scientific explanations: explaining is an act of actively responding to explanations presented by others ; the actual experience of explaining involves the enactment of power and authority; resistance might be a constitutive part of learning how to explain. These assertions expand the possibilities of dialogue between studies of scientific explanations and the social sciences. Implications for science teaching and research in science education are presented.

This paper provides a systematic literature review, analysis and discussion of methods that are proposed to practise ethics in research and innovation. Ethical considerations concerning the impacts of R&I are increasingly important, due to the quickening pace of technological innovation and the ubiquitous use of the outcomes of R&I processes in society. For this reason, several methods for practising ethics have been developed in different fields of R&I. The paper first of all presents a systematic search of academic sources that present and discuss such methods. Secondly, it provides a categorisation of these methods according to three main kinds: ex ante methods, dealing with emerging technologies, intra methods, dealing with technology design, and ex post methods, dealing with ethical analysis of existing technologies. Thirdly, it discusses the methods by considering problems in the way they deal with the uncertainty of technological change, ethical technology design, the identification, analysis and resolving of ethical impacts of technologies and stakeholder participation. The results and discussion of our literature review are valuable for gaining an overview of the state of the art and serve as an outline of a future research agenda of methods for practising ethics in R&I.

Este ensaio busca analisar a representação conceitual do Exame Nacional do Ensino Médio (ENEM) para além do senso comum. Assim, o nosso objetivo geral é discutir a interface da avaliação educacional e as políticas públicas. _Para tanto, busca se _compreender os determinantes impostos na representação conceitual do Exame Nacional do Ensino Médio (ENEM) como modelo de gestão do espaço escolar. _Isso se apresenta como forma de romper com a hegemonia que se encontra presente no senso comum do ENEM apenas como avaliação de ingresso no ensino superior. _A metodologia utilizada encontra-se no campo da teoria crítica, no sentido de apropriação do conceito de avaliação educacional. O estudo se justifica ao constituir aspectos interpretativos referentes aos sistemas de avaliação educacional que possam, efetivamente, direcionar para proposições de melhoria da qualidade da educação. Concluímos que se torna importante que os educadores, em sua atividade educativa, tenham a compreensão política do papel que desempenham em democratizar o acesso à cultura escolar e rejeitem a compreensão tecnicista de curso preparatório para o vestibular quando o ENEM ficar associado, exclusivamente, a um mecanismo de ingresso ao ensino superior. Isso implica compreender que a educação básica, como um todo, é um lugar de formação e o ingresso no ensino superior é decorrência desse processo formativo. _Nesse contexto, a formação profissional do sujeito, numa sociedade democrática em todas as instâncias, seria a posição do saber fazer como elemento de acesso a todos que participam e usufruem da ciência e tecnologia como instrumento do pensamento crítico e efetiva melhoria da qualidade de vida de toda a população._.

This open access collection of AI ethics case studies is the first book to present real-life case studies combined with commentaries and strategies for overcoming ethical challenges. Case studies are one of the best ways to learn about ethical dilemmas and to achieve insights into various complexities and stakeholder perspectives. Given the omnipresence of AI ethics in academic, policy and media debates, the book will be suitable for a wide range of audiences, from scholars of different disciplines (e.g. AI science, ethics, politics, philosophy, economics) to policy-makers, lobbying NGOs, teachers and the educated public.
