趣闻与生物学基本概念

生物学中饶有兴趣的琐事非常丰富。诸如长有尾巴的婴儿,贪食河豚鱼中毒等等。然而这些生活中极普通的趣闻,在提高生物学课堂教学质量上也会起着一定的作用。我把弗兰纳里撰写的这篇文章,节录献给读者能够得到有益的启发。     

The complexity of trauma response: a 4-year follow-up of adolescent Cambodian refugees

OBJECTIVE: The objective of this study was to document the psychosocial adjustment of young refugees during their adolescence and its association with the war-related trauma experienced by their family before migration. METHOD: Data were collected on 57 young Khmer resettled in Montreal and followed from early to late adolescence. The associations between premigratory exposure to political violence and postmigratory mental health and social adjustment were estimated for early, mid-, and late adolescence. RESULTS: The associations between premigratory exposure to political violence and postmigratory psychosocial adjustment fluctuated over the adolescence period. Overall, the adolescents whose families were more highly exposed to political violence tended to report a more positive social adjustment and less mental health symptoms than those less exposed. CONCLUSION: The high expectations of Cambodian parents towards their children and the preservation of traditional values despite the Khmer rouge attempts to eradicate them might contribute to explain the paradoxical association between the families' exposure to political violence and the adolescents' psychosocial adjustment in the host country. Although children and adult refugees seen in clinical setting are reminders of the negative effects of adversity, resilience should be more systematically explored in community samples to further our understanding of the long-term effects of trauma.

动态在线讨论：交互式学习环境中的深层学习

本文阐述了在远程教育中进行面向深层学习的动态在线讨论的一个框架。该框架建立在信息、方法和认知等三个普遍性过程的基础上。在本框架中进行动态讨论的结构包括三种在线讨论的类型,即灵活的同伴、结构化的主题和协作性任务讨论。该框架在一门有关教学多媒体设计的在线研究生课程中使用过两个学期。创建动态讨论的策略是为了促进不同学习者之间的在线交互,并有助于设计能实现有效交互的任务。学生通过设计的任务产生了接受性学习,在此基础上促进了适应性学习,并且激发了他们促进深层学习的认知能力。该框架及动态讨论的策略提供了一个在线学习环境,在这样的环境中学生的学习超越了既定的课程目标。     

我们对儿童的需要都了解了吗?(一)

看来,没有一个家长会不希望教会孩子劳动,让孩子体验劳动的乐趣的。但是我们平时所采取的教育方法,对待孩子的习惯性方式,是否都能促进(或者只要不妨碍)孩子们对劳动本身兴趣的巩固呢?
