钢筋增强超高韧性水泥基复合材料梁的剪切性能试验研究

目的：揭示不同剪跨比和配箍率的钢筋增强超高韧性水泥基复合材料（RUHTCC）梁的抗剪性能,为超高韧性水泥基复合材料（UHTCC）用于结构关键抗剪部位提供参考。方法：基于抗剪试验结果,阐明剪跨比和配箍率对RUHTCC梁抗剪性能的影响,明确UHTCC与箍筋之间的复合抗剪效应,揭示 RUHTCC 梁的抗剪机理。方法：以剪跨比和配箍率为变量参数,通过 RUHTCC梁在跨中集中荷载作用下的弯曲试验,研究RUHTCC 梁的剪切裂缝形态、荷载-挠度行为、破坏模式、开裂剪切强度和极限剪切强度等抗剪性能,并结合试验结果,分析 RUHTCC 梁的剪力传递机理。结论：1. RUHTCC梁呈现出优良的剪切抗力以及稳态的斜裂缝扩展过程和多缝剪切开裂行为。2.配置少量的箍筋可将典型的剪切破坏转变为较为延性的弯剪破坏甚至弯曲破坏。然而,箍筋的配置并未显著提高 RUHTCC 梁的抗剪能力,同时耦合UHTCC与箍筋也没有表现出协同抗剪效应。3.拉杆-拱模型和桁架-拱模型可用以描述RUHTCC短梁和细长梁的抗剪机理。

探索有效终身学习之指标:“学习能量”及其动态测评

“学习能量”有关学习的倾向、态度和价值观,是英国教育界近年来出现的讨论“学会学习”的一种新的话语.它包含了改变与学习、意义建构、探究意识、创造力、学习关系、战略意识和心理弹性七大维度.“有效终身学习指标”作为其动态测评工具,对教学和科研的意义重大.“学习能量”为切实改进教学法、进行课程变革、开展个性化学习以及发展终身学习型社会提供了有力的理论依据和实践框架.它最大的创新之处在于激发并解放了学习者终身学习的能动性,对进一步深化中国的教育改革有着重要的启示.     

学前教育中羌文化传承的“生态语境”与“叙事体验”探究

羌文化是多元文化中的重要一支,却面临着羌语濒危,文化主体、文化传承“生态语境”缺失,文化传承行为严重失衡等现实困境.学前儿童是未来文化主体,教育是人类文化得以传承的主要途径,学前教育是实施民族文化传承教育的关键期和重要期,学前教育中羌文化传承“语境”损毁而导致羌文化传承教育弱化.因此,塑造学前教育羌文化传承的“生态语境”,突围羌文化传承困境,实施学前儿童羌文化传承“叙事体验”教育,是学前教育羌文化传承的有效建设和重要驱动.     

High school boys’ and girls’ writing conceptions and writing self-efficacy beliefs: what is their role in writing performance?

This study investigated the conceptions about writing and writing self-efficacy beliefs held by high school students in relation to the students’ gender as well as their associations with writing achievement. The results show that female students have more sophisticated writing conceptions than their male counterparts but no gender differences were found in writing self-efficacy beliefs. In addition, results reveal that writing self-efficacy beliefs and gender play an important role in predicting writing performance and that writing performance is moderated by students’ writing conceptions. Educational implications and further research are discussed.     

Cross-cultural Perspectives of Successful Aging: Young Turks and Europeans

Successful aging (SA) has been conceptualized in a number of ways. Despite increasing research into how laypersons define SA, few studies capturing lay perspectives of SA in younger cohorts and in non-English speaking countries have been undertaken. The current study examines cross-cultural perspectives of SA in young (aged 18–35), lay adults from a variety of continental European countries and Turkey. Participants were recruited via snowball sampling from social network sites and invited to participate in an online survey. Persons between 18–35 years from Belgium, Estonia, Germany, Netherlands, Romania, Switzerland, or Turkey were included. Respondents (total: 390; Belgian: 32; Estonian: 96; German: 76; Romanian: 47; Swiss: 39; Dutch: 30; Turkish: 70), were primarily women (56.4%) and students (66.2%), with an average age of 24.1 years (SD 3.7). Personal resources, social and active engagement all emerged as dominant themes across countries, but were articulated in subtly different ways in the participant countries. Positive perspectives, desirable attributes and satisfaction themes were intertwined within themes of acceptance and engagement. The current study provides a first step in the inclusion of geographic and cultural diversity into the SA literature. These results suggest that layperson conceptualizations of SA have broad-sweeping similarities, but further research is required to articulate the nuance of cultural influences on SA.     

Embedded creative workers and creative work in education

This article is concerned with the many connections between creative work and workers, and education work and industries. Employment in the education sector has long been recognised as a significant element in creative workers’ portfolio careers. Much has been written, for example, about the positive contribution of ‘artists in schools’ initiatives. Australian census analyses reveal that education is the most common industry sector into which creative workers are ‘embedded’, outside of the core creative industries. However, beyond case studies and some survey research into arts instruction and instructors, we know remarkably little about in which education roles and sectors creative workers are embedded, and the types of value that they add in those roles and sectors. This article reviews the extant literature on creative work and workers in education, and presents the findings of a survey of 916 graduates from creative undergraduate degrees in Australia. The findings suggest that education work is very common among creative graduates indeed, while there are a range of motivating factors for education work among creative graduates, on average they are satisfied with their careers, and that creative graduates add significant creative-cultural and creative-generic value add through their work.     

Use of sexuality-focused entertainment media in sex education

The literature on the impact of entertainment media on sex education is typically pathology-focused, unclear regarding the effects of such usage, and void of dialogue between those who actually work in the areas of sexuality education and entertainment. To address this gap, this paper is the product of joint authorship between media figures from varied sexually-focused programming fields and academics who teach and conduct research in the areas of sexuality and relational health. The authors focus on the role that various forms of entertainment media play in educating members of the public and college classrooms in the areas of sex and sexuality. Additionally, examples of the inclusion of entertainment media in educational contexts are discussed.     

行动学习及其在高中学科教学中的应用

行动学习是一个以完成预定的任务为目的、通过解决实际问题、在同伴支持下持续不断地反思自己的经验、相互学习与提高的过程,它的理论基础是经验学习循环圈理论和建构主义学习理论,实施过程可概括为“四阶六步”.将行动学习应用于当前高中学科教学,使教师成为行动学习顾问,使学生成为解决问题主角,使高中课堂充满生命活力.其实施过程为提出问题、组建团队、制定方案、解决问题、总结评估等五个步骤.行动学习应用于高中学科教学的功效保障在于提高教师专业发展水平、构建和谐的师生关系以及改变专断僵化的学校管理体制.
