化学新课程改革与微型化学实验

新一轮基础教育改革中，化学新课程改革在理念和内容上都强调学习方式的转变，即倡导探究性学习．探究性学习的实质，是学生主动参与教学过程，积极从事各种探究活动，亲自发现科学概念和原理，掌握探究技能．事实表明微型化学实验是实现探究性学习的有效手段．

In the flesh: a poetic inquiry into how fat female employees manage weight-related stigma

ABSTRACT

This paper engages with the question of how fat female employees manage weight-related stigma at work. We use poetic inquiry to show the reader how it feels for our participants to be stigmatized based on their size. We interviewed 22 women who self-identify as full-figured, fat, overweight, or obese. The results consist of six poems, five of which were written by us, the researchers. These ‘tri-voiced poems’ (Leavy 2010b) illustrate the spectrum of affective responses and stigma management strategies that our participants talked about, ranging from feeling anxious, super-smart, impeccable, and funny to rebellious and confident. The sixth poem was written by one of our participants and voices her first-person experiences and perspective. Our aim is to do justice in our writing to the emotions that circulated in the interviews and to make a political statement with regards to the stigmatizing practices in organizations related to size and health.     

‘Miss mum’: mind and affective experience of Korean learners identified with autism spectrum and cognitive difficulties

Responding to the call for culturally informed research on autism spectrum (AS) to allow for the provision of appropriate services, this paper qualitatively explores the affective experience of five Korean learners identified with AS and cognitive difficulties by listening to their voices. The learners, supported by the use of visual aids and a choice of their preferred mode of communication, expressed the complexity of their inner experience that encompassed abilities as well as difficulties. The findings highlight the commonalities of experience between Korean and non-Korean individuals with AS, along with some aspects specific to the Korean cultural context.     

Undercover policing and the spectre of ‘domestic extremism’: the covert surveillance of environmental activism in Britain

The spectre of environmental ‘domestic extremism’ has long been postulated by police leaders and security analysts in Britain. It is a narrative that has justified the commitment of enormous amounts of government resources towards police intelligence work directed at non-violent direct action campaigns. Most controversially, this has included the long-term infiltration of environmental (and other) activist groups by undercover police. This article provides a critical analysis of the justifications put forward in support of the covert surveillance of environmental activists in Britain. The paper proceeds by way of a single case study – a high profile, environmental direct action protest in the north of England – in order to reveal the levels of abuse, manipulation and deception at the basis of undercover protest policing. Through their court case, the activists involved with this action were able to obtain rare insights into the police authorisation documents for the undercover operation that had led to their arrests. An analysis of these documents provides us with a glimpse of the contradictory justifications given by senior police officers for infiltration – now under scrutiny by a public inquiry.     

Developing a multi-level organization-public dialogic communication framework to assess social media-mediated disaster communication and engagement outcomes

Dialogic communication has long been viewed as vital for effective organization-public relations. Yet, it is under-theorized whether and how organizations’ disaster communication messages may embody dialogic communication principles, and how various dialogic features are associated with different public engagement outcomes on social media. Extending the Organization-Public Dialogic Communication (OPDC) framework to the context of social media-mediated disaster communication, we propose a multi-level framework to assess the dialogic capacity of Facebook messages sent by disaster management organizations during a natural disaster. Three levels of dialogic communication characteristics (i.e., message structure-level, topic-level, and linguistic level) are examined using content analysis and Linguistic Inquiry and Word Count (LIWC). Results identified media richness, correcting, and confirming topics as three consistent predictors of public engagement of all types. Meanwhile, there exhibit greater variations regarding how other topical features and linguistic characteristics are related to public’s cognitive, emotional, and behavioral engagement during a disaster.     

论探究概念在杜威哲学中的重要地位

“探究”是杜威思想中的一个核心概念,可以看作是杜威思想的核心方法论,用探究概念来建构杜威的思想体系,可以把杜威在形而上学、语言哲学、知识论、逻辑思想等相邻领域的理论整合起来,这样能够比较全面地展现杜威在这方面的思想全貌。杜威的“真理观”、“发生学方法”、“经验自然主义”、“工具主义”、“操作主义”等也可以纳入到这体系之中来进行探讨。     

基于实证调查的街旁绿地价值研究——以舟山浦西公园为例

街旁绿地是城镇空间中可供民众游憩、观赏、健身、幽会的边角小空地,由于其微小且零散依附于主要建筑环境与交通流线之间,极易被忽略、侵蚀或转换成其他商用价值较大的功能空间。通过实地踏勘、观察体验、问卷调查及专题访谈等综合实证调查,分析总结民众对舟山浦西街边绿地公园的使用现状及期望,提出街旁绿地景观环境的优化策略,以期创造一个民众喜爱的城镇景观生态不可或缺的人性化场所,为城镇设计提供借鉴。     

Using the community of inquiry for interviewing children: theory and practice

Involvement of children in research processes requires various ethical considerations. In particular, while interviewing children, a researcher needs to take into consideration the power imbalance between a researcher and children as well as among children. This article suggests a possible way of mitigating potential risks, drawing on the idea and practice of the Community of Inquiry (CoI) as an interview method. CoI is the practice of group dialog for knowledge-making, where participants talk about a common topic by sharing their lived experiences in a cooperative manner. This article shows that CoI allows children to act as both interviewers and interviewees, which helps children in reflective knowledge-making while at the same time mitigating the ethical concerns of interviewing. To illustrate how CoI can help achieve these goals, this article draws on the empirical research conducted with a group of junior high school students in Japan.     

Theoretical Factors Influencing Adolescent Sexual Behavior: Evidence from a Rural Sample Living in Poverty

ABSTRACT

This study of 414 adolescents who resided in rural Arkansas families receiving AFDC was designed to investigate what theoretical factors predicted frequency of sexual intercourse in the past year prior to the study and number of lifetime sexual partners among males and females. Multivariate analyses indicated that elements of bonding were important to the sexual behavior of females, but not males. On the other hand, feelings of frustration influenced male sexual behavior only. The number of sex partners was increased by associations with sexually active peers for both genders while only females made excuses. The only factor which was associated with both sexual behaviors among both genders was having sex to have a baby to love or to draw a partner closer. The family social work implications of these findings were discussed.
