Children As Design Visionaries, Learners, And Socio-Political Wayfinders: Mapping The Layers, Hierarchies, And Rhythms Of A School Community, Natalie R. Davis, Roni Barsoum

Occasional Paper Series

Despite the seemingly intractable problems of public schooling, we (as researchers and dreamers) remain encouraged by the persistent efforts to reconfigure and reimagine the sociopolitical landscape of schools. We begin this essay by recognizing the work of individuals bravely and imperfectly expanding notions of what schools could and should be. We stand in solidarity with the innovators sowing, designing, and reaching toward more just social futures, dreaming of schools for children that are not so distant from the paradise Butler (2001) describes (Figure 1). This liberatory dreamwork coincides with long histories of communal ingenuity (Vossoughi et al., 2016), resistance against …

Reviving Knowledges Through Play And Resistance: The Case Of Navajo Conceptions Of Space, Daniel Ness, Richard D. Sawyer

Northwest Journal of Teacher Education

The authors explore a possible cause of epistemicidal predispositions of the dominant Eurocentric curricula. They posit that one way to determine a plausible contributing factor of this increasing devastation is to consider epistemicide through the lens of intellectual development. To do this, the authors examine parallel patterns of behavior in the domains of developmental and cognitive psychology. The authors then discuss an alternative framework to the Western conception of space within formal K-12 education by presenting the Navajo conception of space and play. Throughout the paper, the authors argue that all students—and especially those living in poverty in commercially constructed, …

The Museum As Object Of Display: Experiencing The Ashmolean, Jack Z. Chen

Armstrong Undergraduate Journal of History

Conventionally, museums are most often considered as a series of objects displayed, but I argue that the museum itself should be seen, first and foremost, as the object on display. The Ashmolean Museum in Oxford, built at the high tide of British Imperialism, is a very interesting case study. Interested in its engagement with its own past, I do not seek to investigate the actions it takes as an institution, for instance, as regards to the politics of repatriation. Instead, I want to explore the whole experience it facilitates as an object in its own right.

This experience begins with …
