15. Perpetuating Student Inequality? The Discrepancy and Disparity of Global Citizenship Education in Chinese Rural & Urban Schools

Author

LI, Cuicui

Abstract

Global citizenship education (GCE) has been implemented in schools as an approach to address growing global issues and increase the internationalization of education. From critical discourse, however, the implementation of GCE seems to be thwarted by neoliberal practices that deepen societal inequality and gaps, and only benefit members of elite groups. This study aims to analyze teachers' perceptions and the school-based concrete implementation of context-specific GCE in China, unveiling not only the co-existence of neoliberal and moral perspective in teachers' conceptual framework, but the key role that teachers and schools play in the implementation. It argues that sampled teachers follow inclusive understandings of global citizenship, their definitional frameworks were profoundly shaped by the multiple interplays between global forces, official discourses, and moral tradition. Given that a central characteristic of GCE is working as an "axis" to group the cross-cutting themes or initiatives of global dimensions within a range of courses and across school ethos, extra-curricular activity and international program in particular. The discrepancies and disparities in GCE development seen between rural and urban schools extend education inequality from local to the global sphere, in which underprivileged students have heightened risks of being marginalized in the global world.

Abstract

In this article, we investigate the boundary blow-up problem Δ∞hu=f(x,u),inΩ,u=∞,on∂Ω,\left\{\begin{array}{ll}{\Delta }_{\infty }^{h}u=f\left(x,u),& {\rm{in}}\hspace{0.33em}\Omega ,\\ u=\infty ,& {\rm{on}}\hspace{0.33em}\partial \Omega ,\end{array}\right. where Δ∞hu=∣Du∣h−3⟨D2uDu,Du⟩{\Delta }_{\infty }^{h}u=| Du\hspace{-0.25em}{| }^{h-3}\langle {D}^{2}uDu,Du\rangle is the highly degenerate operator related to infinity Laplacian which comes from the absolutely minimizing Lipschitz extension and has a close relationship with the random game named tug-of-war. When the function ff satisfies the Keller-Osserman-type condition, we establish the existence of the boundary blow-up viscosity solution. Moreover, for the separable case f(x,u)=b(x)g(u)f\left(x,u)=b\left(x)g\left(u), we establish the asymptotic estimate of the blow-up solution near the boundary under some regular conditions of the domain. Based on the asymptotic estimate and comparison principle, we obtain the uniqueness of the large viscosity solution. During this procedure, we also study the non-existence of the large solution. For the separable case, we show that the Keller-Osserman-type condition is sufficient and necessary for the existence of the boundary blow-up viscosity solution.
