教育理论思维的公共性诉求

思维方式深层影响着教育理论研究.从方法论的维度看,公共性的极至崇拜和公共性的完全消解的相异思维方式同时影响着教育理论思维.为避免在两极间徘徊,应寻求一个基于实践的公共的教育理论论域,以基于实践的公共性诉求来理解、探求教育理论,并以爱教育的人间关怀使研究充满活泼的生命力.     

一种基于椭圆曲线的部分盲签名方案

椭圆曲线数字签名实际上是基于乘法群的离散对数的数字签名在椭圆曲线上的模拟。本文讨论了部分盲签名的概念,并提出了两个基于椭圆曲线的部分盲签名方案,即单密钥部分盲签名方案和双密钥部分盲签名方案。该方案主要用于提高离线电子系统的效率和需要较短密钥的应用产品。     

A note on the mean residual life of a coherent system with a cold standby component

In this paper, we investigate the effect of a cold standby component on the mean residual life (MRL) of a system. When the system fails, a cold standby component is immediately put in operation. We particularly focus on the coherent systems in which, after putting the standby component into operation, the failure of the system is due to the next component failure. For these systems, we define MRL functions and obtain their explicit expressions. Also some stochastic ordering results are provided. Such systems include k-out-of-n systems. Hence, our results extend some results in literature.     

Managing diversity: academic’s perspective on culture and teaching

As UK Higher Education institutions continue to accept students from ethnically diverse backgrounds, there is now an onus and an expectation for academics to provide learning environments and experiences that are inclusive, validating and affirming. The aim of this paper is to explore, through the lens of the academic tutor, the pedagogical methods employed towards the implementation of ‘cultural branching’, which we define as helping ethnically diverse students to build bridges between their pre-existing knowledge and what they are expected to learn. To investigate this in more detail, the researchers interviewed 22 academic tutors across three UK Higher Education Institutions in the North of England. The findings suggest that current curriculum structures and pedagogical approaches favour the dominant non-ethnically diverse learner. Our research proposes that additional emphasis needs to be placed on developing a practical and functional approach which embeds cultural branching via technological platforms.     

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.     

语境与诠释:论中国教育学的研究范式

范式在中国教育学界的理论旅行,生成了三种不同的语境.本文基于文本阐释学的"过度诠释"概念,指出了解读教育研究范式的合法性理路,分析了库恩意义上的范式和胡森意义上的范式之间的联系与区别,从而揭示出教育研究范式的理论内涵.笔者指出,在我国当前的教育研究语境下,库恩意义上的范式转换是不存在的,而胡森意义上的范式转换则是可能的 ,这有助于"教育研究范式"的意义理解和研究深化.     

Reclaiming ourselves through Testimonio pedagogy: reflections on a curriculum design lab in teacher education

This article details one teacher preparation course centering Latin American Testimonio narratives of struggle/survival amid structural oppression for use in secondary curriculum. As our class of predominantly Latina/o students and two Latina instructors engaged Testimonio pedagogy, we fashioned a hopeful alternative to our own experiences of intergenerational oppression. While research indicates that the experiences and histories of pre-service Teachers of Color lend pedagogical strength and critical consciousness to teacher education, three Latina pre-service students highlight the ways in which Testimonio became more than a pedagogical approach. Testimonio’s collectivity, resistance, hope, and assertions of voice and dignity moved through them not as educators first but as (great-grand)daughters of oppressed though still-resilient People(s). Testimonio emboldened these Latina pre-service educators to recognize and validate their own inherited multiliteracies, (re)claim their connectedness to land, and articulate their visions for more equitable schooling. This work advances research into the essentiality of engaging race and ethnicity in K-12 and teacher education curriculum and pedagogy.     

略论电子签名证据相关问题

随着网络技术的不断发展,计算机犯罪和网络犯罪呈上升趋势,犯罪手段越来越多样化,技术越来越高超。在司法实践中,当网络传输中数据电文作为证据使用时,法院无法准确判断其是否被篡改。而电子签名技术能够保证数据电文在网络传输过程中不被人偷窥、窃取、删改或是假冒。因此,电子签名可以作为数据电文的辅助证据使用。在证据法上,赋予电子签名以证据效力并确保其证据效力的优势有实际意义,使电子商务更具有法律保障的基础。     

教育公平的基本内涵及实现路径

为促进社会流动的公平性,基于经济学和社会学的相关理论分析教育的三个基本属性(准公共产品性、外部性和第三部门属性)及教育公平的基本内涵;进而从义务教育和高等教育两个方面剖析教育的不公平现象及其根源。在此基础上提出教育公平的实现路径:政府应当对教育资源进行合理配置,向义务教育倾斜,向薄弱学校和弱势地区倾斜;可以通过选择教育券制度实现教育公平。     

科研论文买卖现象的透视及破解

根据科学共同体长久以来的惯例和我国著作权法的相关规定,只有进行了实际创作,对作品的完成具有创造性贡献的作者才有署名权。当下我国所出现的科研论文买卖行为已成为一个较普遍的现象,这一行为的性质既属于科研道德问题,也是一个亟待解决的法律问题。论文买卖现象有其出现的特定背景和原因,从产生的原因入手进行治理,可以找到解决问题的根本途径。
