分布异构环境下重用遗产软件的研究与应用

在深入研究现有遗产软件重用技术和方法的基础上提出了组合Agent-Component（AC）来重用遗产软件的思想,为分布异构环境下遗产软件的重用提供了一个新的思路和途径,最后通过一个高校教务子系统的实例,进一步描述了采取组合AC模型来实现分布异构环境下重用遗产软件的思想。     

从教育目标分类学看语文学科核心素养论

将“语文素养”和“语文学科核心素养”概念及其界说置于2001年《学习、教学和评估的分类学:布卢姆教学目标分类学修订版》的知识与认知过程两维目标分类框架中考察,并将它们与叶圣陶语文教育思想相对照,结果表明,前者的依据是“语感论”,在回答语文课教什么和怎么教方面仍需进一步探讨;后者与当代认知心理学的知识、技能与能力的学习理论大方向一致,但需要与时俱进,并深入研究语文课怎么教的问题。新近小学语文教材编者提出“语文要素”概念,并努力“构建语文能力发展训练体系”。这是小学语文教育指导思想对叶圣陶的“知识—训练—技能”路线的回归;但若向其中注入知识与认知过程两维目标分类思想和现代心理学的学习分类理论,则能更科学、有效地解决语文课教什么和怎么教的问题。     

Loneliness,personal and social well-being: towards a conceptualization of the effects of cyberbullying / Soledad,bienestar social e individual: hacia una conceptualización de los efectos del cyberbullying

This paper examines the effects of cyberbullying using a mixed method approach, by combining interviews, focus groups and a survey of 7,000 students. In the inductive stage, and following an axial coding analysis, we identified 153 concepts related to conflicts, which were divided into three thematic units to explain the greater impact of cyberbullying: (1) social distance; (2) privacy exposure; and (3) range of the material. The survey concluded that: (1) the victims of bullying and cyberbullying present higher levels of loneliness and lower levels of social well-being compared to non-bullied students, and those who were bullied in both channels presented higher levels of loneliness and lower levels of social well-being than those who were bullied in only one of them; (2) the victims of cyberbullying showed lower levels of individual well-being compared with those who had never been bullied, as with those who suffered face-to-face bullying. This difference was explained by testimonies indicating that most of the cyberbullying was related to intimate content, which has a higher impact on image perception.

Improved Genetic Algorithm and its Performance Analysis

Although genetic algorithm has become very famous with its global searching,parallel computing,better robustness,and not needing differential information during evolution.However,it also has some demerits,such as slow convergence speed.In this paper,based on several general theorems,an improved genetic algorithm using variant chromosome length and probability of crossover and mutation is proposed,and its main idea is as follows:at the beginning of evolution,our solution with shorter length chromosome and higher probability of crossover and mutation;and at the vicinity of global optimum,with longer length chromosome and lower probability of crossover and mutation.Finally,testing with some critical functions shows that our solution can improve the convergence speed of genetic algorithm significantly,its comprehensive performance is better than that of the genetic algorithm which only reserves best individual.     

幼儿生活教学的价值取向

从马克思开始的现代哲学吹响了由科学世界观转向生活世界观的号角,哲学视野的这一转向也促使"教育回归生活世界"理念的生成与彰显,植根于幼儿生活世界的"生活教学"成为幼儿教育践行这一理念的根本途径.幼儿生活教学只有取向于幼儿"真实的生活世界""生态的整体生活""多元的个性生活"和"当下的现实生活",才能实现幼儿教学的本体性价值--关注人自身的生存与发展,进而改造与重建幼儿的教学世界和生活世界,赋予教学以生活的本真意蕴.
