新世纪第一个10年中国教育技术学科的国际交往研究

我国教育技术起步较晚,大部分理念和技术都是从国外引入并逐步加以本土化的。国际交往对于我国教育技术的发展具有很大的作用,作为我国首次全方位关注教育技术国际交往的研究,其意义就更为重要。21世纪以来,我国教育技术领域的国际交往越来越频繁,当前的主要途径有国内师生出访交流,国外学者来华作报告、进行合作交流,对国外学者进行专访对话,学者赴外参加国际会议或国内举办国际会议,以及翻译国外著作等。10年来,随着国际合作内容不断丰富,其研究越来越广泛并走向深入,主要集中在学科发展、远程教育和学习模式等10个领域。这些国际交往使我国教育技术学科地位得到巩固和发展,研究领域得到拓展,研究方法更加科学和规范。评估10年的国际交往,今后更应加强实质性合作研究,提高交流实效,重视国际项目合作,避免停留在表面或流于形式,要以一种平等合作、批判性、包容性的态度进行国际交流和对话。

构建新型中等职业教育理念的思考

各国教育理念反映了该国对教育价值的基本取向,对教育理论与实践的发展起着明显的指导作用,为跟上知识经济、城镇化,工业化等发展的步伐,推动社会经济与人的可持续发展,我国必须构建适应时代需求的中职教育理念,以科学指导中职教育的办学定位及其实践.     

OSI参考模型的教学方法

《计算机网络基础》课程是一门发展着的前沿学科,是我院本、专科各专业必修的一门专业基础课程,是通信技术与计算机技术相结合的产物,内容广泛,学习难度较大,尤其在学习计算机网络体系结构这部分知识时,学生的学和教师的教都认为是一重点,也是一难点。所以,本文将从一实例出发逐渐推导出计算机网络体系结构模型OSI/RM的教学内容,从而使学生进一步了解什么是计算机网络体系结构。     

Curriculum stasis: the disconnect between music and technology in the Australian curriculum

Technology is a dominant mediating factor impacting on current human behaviour and social change, which both acts on and is acted upon by other phenomena. This changing social landscape, along with new expectations and requirements, drives our educational priorities and curriculum agenda. There is no denying the prevalence of technology found in the statements and guidelines of the national Australian Curriculum. Further, the National Review of School Music Education identified the importance of technology in school music education in 2005. The curriculum guidelines illustrate an understanding of technology in Music and the Arts that is both vague and limiting. In 2015 we are at a point of curriculum stasis, an equilibrium that highlights a disconnect between music, technology and Australian music education. This article investigates current secondary school Years 7–10 (ages 11–15 years) Music and Arts curriculum statements concerning the use of technology and compares this to the general capability information and computer technology (ICT) curricula. There is wide recognition that digital technology is essential in teaching and learning, but this is not reflected in contemporary Australian Arts and Music curricula.

Interactive Effects Between Maternal Parenting and Negative Emotionality on Social Functioning Among Very Young Chinese Children

Research Findings: This study examined how child negative emotionality interacted with mothers’ self-reported parenting in predicting different aspects of social functioning among very young Chinese children. A total of 109 Chinese nursery children in Hong Kong participated with their parents. Maternal supportive and aversive parenting practices were reported by mothers, and child negative emotionality and social functioning were reported by both mothers and fathers. The results revealed interaction effects between child negative emotionality and mothers’ self-reported parenting on children’s internalizing problems, externalizing problems, and social-emotional skill deficiency. Specifically, children with high negative emotionality were more susceptible to the negative effects of aversive parenting (i.e., showing more internalizing and externalizing problems when exposed to aversive parenting) than their peers with low negative emotionality. Negative emotionality also placed young children at risk for social-emotional skill deficiency, especially when they received less support from their mothers compared to their peers. Practice or Policy: Special attention should be paid to the social functioning of Chinese children with higher levels of negative emotionality, because these children are more vulnerable to poor-quality parenting at a very young age.

结构性失业与高教政策调整

目前“知识失业”作为一共同难题正严重困绕着世界上几乎每一个国家。自1999年来，我国大学生就业率持续四年走低，引起社会各界的广泛关注，有人用“过度教育”理论来解释这一现象，然而，教育过度只是一种表象，实质是由于教育结构与经济结构之间的矛盾引起的结构性失业，调整高教政策以适应经济的发展在很大程度上能解决大学生就业问题。
