The political dimension in ESE: the construction of a political moment model for analyzing bodily anchored political emotions in teaching and learning of the political dimension

This article departures from the understanding of environmental sustainable education (ESE) as a political project that consists of dissonant and conflicting voices. The aim of the article is to understand how affection, i.e. bodily sensations, transform into political emotions in teaching and learning settings. The article offers a philosophical and empirically based model called the ‘political moment model’ for analyzing bodily anchored political emotions in teaching and learning of the political dimension. The model was developed in response to an empirical case study where the data were somewhat confusing. In order understand the empirical data, we used parts of Mouffe’s theory of the political and various scholars’ work on political emotions and placed these aspects in a pragmatist standpoint of experience, emotions and meaning making. The model helped to investigate students’ experiences of the political dimension in situations where they experienced affection, i.e. bodily sensation, and emotions in connection with reflections and discussions about how to handle public issues of sustainable development. The article ends with a theoretical discussion of the findings in order to understand the political dimension in teaching and learning activities and to discern possible directions for future research on political moments in ESE.

乒乓球与球拍之间的摩擦

现代乒乓球运动中几乎所有技术都要借助于摩擦。制造旋转时，球拍与球之间的摩擦主要是静摩擦和滚动摩擦，它们的作用效果互不相同。静摩擦不但使乒乓球产生旋转，也使乒乓球产生平动；滚动摩擦则不利于乒乓球运动中制造旋转。静摩擦与滚动摩擦都是随时间变化的量，且两者的大小与多种因素有关。
