In this article I discuss how Jacques Rancière’s thought invites us to re-conceptualize the education–emancipation nexus. The primary goal of traditional approaches to emancipatory and anti-oppressive education has been to empower the oppressed so that the latter can (re)gain their voice and transform their situations. Building on Rancière’s ideas, I argue that the processes of empowering the oppressed imply that one has the power to empower the other, and thus start with an assumption of inequality. I conclude the article with a call for a pedagogy of ignorance. Grounded in Rancière’s thought, this pedagogy is ignorant of any division and hierarchy of intelligence.  相似文献

This study examines year-by-year correlations between Freedom House and Reporters Sans Frontières' (RSF) press freedom scores for countries over a 13-year period (2002–2014). The goal of the study is to test the hypothesis that, further into the age of digital disclosure, as press abuses and harassment of journalists are more widely reported, press freedom ranking systems are gradually becoming more precise and, therefore, correlations between the two indices will strengthen over time. To further assess concurrent validity of the indices, correlations between both indices and scores on the United Nations Human Development Index are also provided. The study also examines changes in the indices' rankings of countries over time within six world regions: the Middle East and North Africa, the Americas, Western Europe, Eastern Europe/Central Asia, Sub-Saharan Africa, and Asia. In so doing, this study adds a degree of understanding to the validity of two press freedom indices that are routinely cited in journalistic reportage and trade journals, as well as many scholarly publications. Results suggest that the two organizations' scoring of press freedom has become significantly more correlated in the years 2002–2014, and the primary cause of the increased agreement is that RSF's ratings became substantially more aligned with Freedom House's scores during this period. Both indices' ratings are significantly correlated with countries' United Nations Human Development Index scores.  相似文献

The work of philosopher Jacques Rancière is used conceptually and methodologically to frame an exploration of the driving interests in educational technology policy and the sanctioning of particular discursive constructions of pedagogy that result. In line with Rancière’s thinking, the starting point for this analysis is that of equality – that people are legally, morally, intellectually, and in their everyday practices discursively equal. The use of Rancière’s concepts, demos, police, and politics, to analyse three educational technology policies internationally shows that teachers are positioned within these policies as discursively unequal, and as intellectually inferior, not only in terms of technology expertise, but crucially as pedagogues. This positioning has important implications for teachers and teacher education. Teachers are capable of recognising and critiquing inequality, and this article makes a case for an act of politics that aims to reconfigure allocated identities and power imbalances in the educational technology order.  相似文献

As a first step of a project on learning difficulties in elementary set theory, we carried out a study aimed at identifying some of the difficulties encountered by a group of 21 mathematics majors taking a course on logic and set theory. In this paper, we shall discuss one of the difficulties that we observed, namely a difficulty in conceiving a set as an object distinct from its elements, i.e. failing to fully grant sets the status of objects. This difficulty may be related to the following three types of errors that we observed in the students' first assignment: (1) confusing belonging and inclusion, (2) confusing the union of sets A, B, C, ... with the set whose elements are A, B, C, … and (3) adding or deleting curly brackets. We shall present excerpts from the students' work illustrating these three types of errors and explain how they may be related to a difficulty in conceiving a set as an object distinct from its elements.  相似文献
