This article is about how technology and pedagogy is co‐produced in correspondence education. Theoretically the article departs from post‐Foucauldian studies of materiality, and uses the concept of dispositif to construct a framework that is inspired by Foucault, Deleuze, and Actor–Network Theory. Empirically, the article treats how the tension between educational thought on progressive individualism, scientific thinking, and automation was co‐produced with technical artifacts in correspondence education during the 1930s, 1940s and 1950s. The author shows how this co‐production led to a specific mode of organizing correspondence education that tried to accomplish individualization on an industrial basis, and that this mass‐individualization built on a pedagogy of testing, recording, classification, and differentiation. In conclusion the article discusses how mass‐individualization can be seen as an epitome of educational modernity’s aspiration for equality of educational opportunity and progressive thoughts on individually tailored education. Furthermore the author shows that the dispositif of mass‐individualization is closely associated to today’s educational technology, and how today’s educational technology embodies the tension in mass‐individualization. 相似文献

In many Western contexts, travel has a long historical association with youth, young adults and coming of age, an association that often connects temporary mobility with the lives of the educated middle classes and elite. Indeed, from the colonial adventure and the ‘grand tour’, to contemporary ideas of the ‘gap year’ or ‘overseas experience’, the mobility of Western youth and young adults is often considered voluntary and based on a desire to explore places and develop positive personal attributes, marking a stark contrast to depictions of migration from the developing world as directly or indirectly forced and driven primarily by economic considerations. This paper questions this depiction of developed world mobility in the context of the changing economic conditions that face young graduates in many Western countries. Drawing on survey and interview data I focus on the profiles and biographies of young adults from English-speaking countries working as foreign language instructors in South Korea. Although the personal narrative of travel and exploration amongst these individuals remains significant, findings from this research also suggest that many of these young graduates are also driven by economic circumstances: unemployment or underemployment and high levels of debt usually associated with tertiary studies. This tension between the opportunities available to young people and the constraints imposed by their own circumstances raises important questions about the multiple layers of social and economic differentiation operating through higher education and international mobility in the lives of young people. 相似文献

Surface deposits and sediment cores were collected from the Upper Bonny Estuary, located in Southwest Nigeria, and analyzed to determine spatio-temporal and vertical distributions of radio-nuclide activities expressed in Bq·kg?1 dry weight. The results of activities of naturally occurring radionuclides of 226Ra (15 ± 2–34 ± 3 Bq·kg?1), 228Ra (32 ± 5–48 ± 6 Bq·kg?1), 40K (264 ± 29–462 ± 36 Bq·kg?1) were found to be all within the range of typical values reported for coastal regions. Ratios of 226Ra to 228Ra suggested accretion for all samples with low sediment accumulation registered during rainy months. In addition, vertical distributions at the three sampling sites were also studied with the initial aim of establishing chronologies from the decay of excess 210Pb. In two cores, excess 210Pb, estimated by subtracting 226Ra from total 210Pb on a layer-by-layer basis, exhibit relatively constant activity with discrete minima and maxima. Therefore, these cores were excluded from radiometric dating. Only the third core could be dated by the constant rate of supply model, and 137Cs was utilized to validate the 210Pb chronology. 相似文献
