基于学生理解情况研究的浮力教学设计

以问卷调查的形式对当前中学生课前对“浮力”理解情况进行调查。通过调查和研究得到以下结论：初中生认为影响浮力大小的因素中,体积、重量、深度、受力面积、质量、摆放方式所占的比例比较大。据此对“浮力”这一章节的教学设计提出建议。

The role that schools hold in supporting young people with selective mutism: a systematic literature review

Schools are expected to hold an increasingly central role in co-ordinating support for children with mental health needs. However, the role that schools hold in supporting pupils with selective mutism (SM) is complex. Through a Critical Interpretive Synthesis (CIS), this review explores the multidimensional role which educational settings hold in supporting children with SM. Key databases were searched (PsycInfo, British Education Index, Education Resources Information Center, British Library EThOS and Google Scholar) and a conceptual map, informed by experienced practitioners, guided additional purposive searching with a focus on conceptual saturation. A total of twenty-four papers were identified following a further process of appraisal. Reciprocal Translational Analysis (RTA) found that schools hold a tripartite role in supporting children with SM: this incorporated developing a shared understanding of the disorder, engaging in effective (and often multi-professional) planning, and offering direct support through adapting provision and facilitating individual intervention. Through realising this role, schools and educational settings might transform the support currently available for children and young people with SM. Implications for practice, policy and future research also emerged. This included a clear need for enhanced teacher understanding of SM, arguably at the level of initial teacher training (ITT).     

数学理解的三种基本形态及教学启示

数学理解包括三种基本形态,即:记忆性理解、解释性理解和探究性理解,这三种数学理解分别对应着“记得、晓得和明得”三种不同的状态。三种数学理解对数学学习都是有价值的,但仅有记忆性和解释性理解是不够的,探究性理解才是数学教学的最终目标。实践中,不少水平不高的教师常常只能让学生达到记忆性理解,有一定水平的教师能让学生达到解释性理解,真正让学生达到探究性理解的教师并不是很多。教师要不失时机地促进学生数学理解层级的迭代升级,促使学生最终达到探究性理解,吴文俊院士数学学习的经验对把握数学理解的三种基本形态有借鉴和启迪意义。在课堂教学中引导学生从事生动活泼的数学探索性活动常常是一个相当艰难的过程,对教师的数学探究素质提出了较高的要求,教师应努力引导学生去探求数学知识的意义和发现的过程,促使学生数学探究性理解方式的养成。     

Enhancing learning,communication and public engagement about climate change – some lessons from recent literature

This paper sets out to develop key messages for the theory and practice of environmental education from a review of recent research literature on climate change communication (CCC) and education. It focuses on how learners of climate science understand messages on climate change, the communicative contexts for education on climate change, the barriers that can be found to public engagement with climate change issues, and how these barriers can be addressed. 92 peer-reviewed studies were examined. The analysis focuses on the goals and strategies of CCC, and how barriers can be addressed given the research findings on: (a) the content of CCC, (b) visualizations, (c) framing, (d) audience segmentation. The paper concludes that CCC and education need to address barriers to public engagement on several levels simultaneously. It recommends that scholars of environmental education focus critical attention on how practice addresses senses and spheres of agency; sociocultural factors; and the complexities of developing scientific literacy given the interpretative frames and prior understandings that are brought to bear by the public in non-formal education settings.     

反讽理解实验研究综观

为了验证反讽交际认知与理解理论假设的心理现实性,人们做了大量的实验研究,试图寻找实验数据佐证其语用认知心理过程,揭示其语用认知规律和语用认知特征,实验检测的内容包括反讽理解的能力、反讽理解的心理过程以及哪些因素影响反讽理解。结果显示,具备辨别非字面话语的一般认知能力是对反讽做出正确理解的必要基础,至于影响反讽理解的因素以及反讽理解的心理过程,目前没有一致结论。     

关于篮球运动认识过程的分析探讨

采用文献资料等方法。主要结论:理念、意识的提高依赖于人们对事物的深入了解。人们对篮球运动认识上的不同,决定了不同的篮球管理体制、训练体系及竞技风格。实践是"前提",思维是"基础",理念是"保证",意识是"精髓"。它们是认知篮球运动必不可少的。人们是通过它们来理解篮球运动、提高篮球教学训练水平的,并决定在竞赛中采用哪一种技战术的。
