“鲁迅形象”建构的文化语境、过程与反思

"鲁迅形象"是中国现代文化史上典型的现代知识分子的形象符码,其生成过程与现代中国的动态语境密切相关,深刻地勾联了阐释者的文化心理和思维形态。"鲁迅形象"是由自塑和他塑合力而构成的公共形象,对其进行文化学意义上的考察可为探索现代中国发展的社会史和现代知识分子的心灵史提供理论资源。     

共生理论视域下我国融合教育发展的困境与反思

作为一种全新的教育理念,融合教育自提出以后很快成为国际特殊教育的发展趋势。当前,我国融合教育在取得巨大进步的同时,在融合主体的接纳态度与行动支持、教师专业能力与合作意识、融合课程与教学、融合资源投入与共享等方面仍然面临困境。基于共生理论视角对融合教育困境进行理论反思,提出构建融合共生的社会文化环境、建立教师专业学习社群、调整课程与教学、完善资源配置等建议,以期为推进融合教育、提升融合教育质量提供借鉴。     

正本清源：重审游戏精神

“游戏精神”是游戏的灵魂,然而也是一个歧义诸多、意义模糊的概念。由于对这一概念理解上的不明晰,导致当今关于“如何以游戏精神启发实践”的诸多探讨缺乏共同前提,从而阻碍“游戏精神”在教育实践中建构独立的自我生长空间、焕发其自给自足的生命力。在此意义上,作者从游戏精神与游戏的关系、游戏精神的意蕴重审两方面重新审视游戏精神的应然状态,试图为游戏精神“正本清源”。     

幼儿创意绘画教学的常见问题与实施要领

创意绘画是当前比较新颖和盛行的幼儿绘画形式，主要有手指画、画架画、创意涂鸦、喷墨画、粘贴画、三维立体创作等等。创意绘画在开发幼儿动手动脑能力、审美情趣，提高创造力等方面发挥着重要的作用。当前的幼儿创意绘画教学普遍存在着偏向结果且忽视幼儿主体体验、模式固化、成人介入过多等问题。因而，需要教育工作者以及家长正视幼儿创意绘画教学中存在的上述常见问题，正确认识幼儿创意绘画的价值，正确理解幼儿创意绘画的意义，鼓励幼儿在已有简单生活经验的基础之上大胆创作和表达，减少成人的介入与干扰。

Task-based learning approaches for supporting the development of social science researchers’ critical data skills

Conducting social science research is a complex process, and social science students face a number of learning challenges in order to develop their skills. Moreover, new sources and types of data including so-called big data are providing new opportunities for research, but also pose methodological challenges. In this article, we explore a task-based learning approach for teaching social science research methods. We draw on evidence from two case study learning tasks: (i) the collection and analysis of Twitter data; and (ii) designing and conducting a face-to-face and online survey. The students were guided to co-lead the tasks, apply their knowledge and then to critically reflect. The pedagogical framework of task-based learning provides opportunities to embed learning in new ways by integrating knowledge, practice and critical reflection. Task-based learning can create a dynamic learning environment and can empower students to develop their identities as researchers.     

Completing the Circuit: Routine,Reflection, and Ethical Consumption

Efforts to explain why some people incorporate ethical concerns into everyday shopping for food and household goods, while many do not, have so far left significant variation in “ethical consumption” unexplained. Seeking to move beyond explanations that rely mainly on differences in consumers' social class, gender, and political engagement, I draw on concepts associated with “practice theory” to argue that ethical consumption is closely tied to people's willingness and ability to spend time, while shopping, on distinct activities associated with breaking old routines and establishing new ones. The central insight of practice theory is that most consumption is the product of unconscious routine. And it is precisely because consciously departing from routine is, according to my study, a fundamentally time‐consuming process, that lack of time emerges as a crucial obstacle to translating abstract ethical concerns into concrete action as a consumer.
