In this paper we critically review recent developments in policies, practices and philosophies pertaining to the mediation
between science and the public within the EU and the UK, focusing in particular on the current paradigm of Public Understanding
of Science and Technology (PEST) which seeks to depart from the science information-transmission associated with previous
paradigms, and enact a deliberative democracy model. We first outline the features of the current crisis in democracy and
discuss deliberative democracy as a response to this crisis. We then map out and critically review the broad outlines of recent
policy developments in public-science mediation in the EU and UK contexts, focusing on the shift towards the deliberative-democratic
model. We conclude with some critical thoughts on the complex interrelationships between democracy, equality, science and
informal pedagogies in public-science mediations. We argue that science and democracy operate within distinct value-spheres
that are not necessarily consonant with each other. We also problematize the now common dismissal of information-transmission
of science as inimical to democratic engagement, and argue for a reassessment of the role and importance of informal science
learning for the “lay” public, provided within the framework of a deliberative democracy that is not reducible to consensus
building or the mere expression of opinions rooted in social and cultural givens. This, we argue, can be delivered by a model
of PEST that is creative and experimental, with both educational and democratic functions. 相似文献

Student engagement has become problematic following the rise of mass and universal forms of higher education. Significant attention has been devoted to identifying factors that are associated with higher levels of engagement, but it remains the case that the underlying reasons for student engagement and, indeed, the notion itself of ‘student engagement’ remain weakly theorised. In this article, we seek to develop the theoretical basis for student engagement in a way that highlights the student's own contribution. We explore how learning involves students taking responsibility for action in the face of uncertainty, whether in pursuit of personal or communal concerns. Drawing on perspectives primarily from realist social theory, we suggest that student engagement may be shaped by extended, restricted and fractured modes of reflexivity and co‐reflexivity. In this way student engagement in higher education is theorised as a form of distributed agency, with the impact of a learning environment on this agency mediated by reflexivity. Reflexivity itself is further influenced by the tasks and social relations encountered by students in a given learning environment. The role that social relations play in students' responses to learning specifically offers a means to strengthen the moral basis for education. Our account provides an explanation as to why specific educational practices, such as those termed ‘high impact’, might lead to higher levels of student engagement within the wider context of a knowledge society. We thus offer insights towards new forms of educational practice and relations that have the potential to engage students more fully. 相似文献
