The Highway Map Social Studies Resource

Teachers today are more aware of differences in the way students learn and that a wide variety of strategies must be employed when teaching. Major musical films, when appropriately excerpted, can provide an entertaining and unique way of addressing valid instruction objectives in both the cognitive and affective domains. In this article, the authors provide applications of specific Broadway musicals and films to everyday instructional practices.

‘Race’ talk! Tensions and contradictions in sport and PE

Background: The universal sport discourses of meritocracy and equality are so engrained that few challenge them. The most cursory interest in sport, Physical Education (PE), and society will reveal that the lived reality is quite different. Racial disparities in the leadership and administration of sport are commonplace worldwide; yet, from research into ‘race’ in sport and PE, awareness of these issues is widespread, where many know that racism takes place it is generally claimed to be somewhere else or someone else. For many, this racism is part of the game and something to manipulate to steal an advantage; for others, it is trivial. This paper explores the contradictions and tensions of the author’s experience of how sport and PE students talk about ‘race’ and racism. ‘Race’ talk is considered here in the context of passive everyday ‘race’ talk, dominant discourses in sporting cultures, and colour blindness.

Theoretical framework: Drawing on Guinier and Torres’ [2003. The Miner's Canary: Enlisting Race, Resisting Power, Transforming Democracy. London: Harvard University Press] ideas of resistance through political race consciousness and Bonilla-Silva’s [2010. Racism Without Racists: Colour-Blind Racism and the Persistence of Racial Inequality in the United States. Plymouth: Rowan and Littlefield] notion of colour blindness, the semantics of ‘race’ and racialisation in sport and PE are interrogated through the prism of critical race theory (CRT). CRT is used here to centre ‘race’ and racialised relations where disciplines have consciously or otherwise excluded them. Importantly, the centring of ‘race’ by critical race scholars has advanced a strategic and pragmatic engagement with this slippery concept that recognises its paradoxical but symbolic location in society.

Discussion: Before exploring ‘race’ talk in the classroom, using images from the sport media as a pedagogical tool, the paper considers how ‘race’ is recreated and renewed. The paper then turns to explore how the effortless turn to everyday ‘race’ talk in the classroom can be viewed as an opportunity to disrupt racialised assumptions with the potential to implicate those that passively do so. Further, the diagnostic, aspirational, and activist goals of political race consciousness are established as vehicles for a positive sociological experience in the classroom.

Conclusion: The work concludes with a consideration of the uses and dangers of passive ‘race’ talk and the value of a political race consciousness in sport and PE. Part of the explanation for the perpetuation of ‘race’ talk and the relative lack of concern with its impact on education and wider society is focused on how the sovereignty of sport and PE trumps wider social concerns of ‘race’ and racism because of at least four factors: (1) the liberal left discourses of sporting utopianism, (2) the ‘race’ logic that pervades sport, based upon the perceived equal access and fairness of sport as it coalesces with the (3) ‘incontrovertible facts’ of black and white superiority (and inferiority) in certain sports, ergo the racial justifications for patterns of activity in sport and PE, and (4) the racist logic of the Right perpetuated through a biological reductionism in sport and PE discourses.     

Rationalizing Sociality: An Unfinished Script for Socialbots

This article takes the concept and some of the existing applications of socialbots—software robots that operate on social networking sites and present themselves as human users—as an occasion to trace the evolution of online sociality. The argument mobilizes theories of social rationalization from Max Weber to contemporary critical theory to demonstrate that the appearance of automated profiles (socialbots) on social networking platforms can be seen as a logical step in the progressive enclosure of online social interaction in standardized, simplified, and trivialized forms, frames, and gestures. Critical questions concerning what the growth of robo-sociality may mean for individual users and the online public sphere are posed with a view to charting the directions for a needed public debate.     

基于变易理论的体育教学内容分析及其设计策略

摘要：教学内容是体育教学过程中最具核心意义的要素之一。为进一步拓展、深化对体育教学内容及其特性的学理认识,科学有效地选择、设计和呈现体育教学内容,促进学生的有效学习,切实提高体育课的教学品质,主要运用文献资料法和逻辑分析法,在概述变易理论的基础上,重点发掘、阐释体育教学内容的变易特性及其主要类型,并提出基于变易特性的若干体育教学内容设计策略。研究结果表明：1）变易理论的深刻洞见之于体育教学内容的学理认知及其教学设计具有十分重要的认识论和方法论意义;2）体育教学内容具有一般和专项二重属性,并在其关键特征上、学生对其理解上、体育教师对其认识处理上呈现出3种重要的变易,具体又表现为预设的、实践的以及体验到的3种类型;3）重建体育教学内容观,重新审视、认识学生及其学习,选择、确定最有价值、最适切的体育教学内容及其关键特征,设计适切的变易图式,科学处理体育教学内容是帮助学生理解、掌握体育教学内容,进而促进学生更有效地学习的关键所在。     

综合英语课程教学的认知转向探索

受认知诗学理论的影响,综合英语课堂教学将更加注重学生的学习心理过程和学习效果。认知诗学语境下的概念型教学法除了关注英汉对比意识在学生思维中的养成,在综合英语教学中将更多地聚焦于以概念为中心的单元主题在学生认知过程中的内化。概念型教学法的五个教学步骤,即解释、物化、交际活动、言语化、内化,可以有效地将教学内容前景化以提高学生学习效果,并有助于培养学生创造性的学习和批判性思维的养成。
