大学和社会经济发展的关系

在发言开始前,我想对受邀参加本次校长会议表示感谢,并代表开普敦大学以及南非向清华大学表达诚挚的祝贺和良好的祝愿。如同中国大学一样,我国的大学也正逐步融入世界大学群体。由于数十年的种族隔离制度作祟,来自学术界的杯葛接踵而至,南非的大学与国外同行间的合作或交换关系发展得异常困难与复杂。即使在

最危险的污染：核污梁的世界简史

【编者按】日本3．11大地震引发的福岛核电站核辐射灾难,已成地球人再度反思核“安全”的焦点,但很遗憾如果像往常那样,只局促于技术层面去反思,从长远看,毫无疑问,是无济于事的。让人类身陷囹圄的何啻技术,难道出路仍然是创造更好的技术？人类想改变一切,却往往不肯改变自己,自作孽却不自知。核灾难的历史本身,就用毁灭性的事实反复...     

Team-based learning in anatomy: an efficient, effective, and economical strategy

Team-based learning (TBL) strategy is being adopted in medical education to implement interactive small group learning. We have modified classical TBL to fit our curricular needs and approach. Anatomy lectures were replaced with TBL that required preparation of assigned content specific discussion topics (in the text referred as "discussion topics"), an individual self-assessment quiz (IRAT), analysis of the discussion topics, and then the team retaking the same quiz (GRAT) for discussion and deeper learning. Embryology and clinical correlations were given as lectures. Unit examinations consisted of graded IRAT and GRAT. The National Board of Medical Examiners (NBME) Subject Examination was the comprehensive final examination. To evaluate the effect of TBL on student performance we compared the departmental and NBME subject examination scores between the traditional and TBL curricula. We collected five years of data on student performance in TBL-based anatomy and lecture-based preclinical courses. Our results show that departmental and NBME subject examination scores for TBL-based anatomy were higher than those for lecture-based anatomy. We subsequently compared average NBME scores for anatomy with those in other preclinical courses that were lecture-based. Average NBME anatomy scores were significantly higher than those for all the lecture-based preclinical courses. Since the introduction of TBL in anatomy, student performance has progressively improved in the NBME subject examination. Students perceived TBL as a motivator to be a responsible team member and to contribute to collective learning by the team. Further, it reinforced self-directed learning and fostered an appreciation for peer respect. Interestingly, these perceptions were uniform irrespective of student course performance.     

教育数据挖掘工具综述

数据挖掘拥有悠久的历史,它可以追溯到探索性数据分析(Tukey, 1977),且目前已经形成了有效的、可推广的方法.本文将讨论教育数据挖掘研究与实践中逐渐兴起的一些工具,以及在更广泛的层面上数据挖掘和数据科学研究者所使用的相关工具,近40种教育领域数据挖掘与分析的常用工具,包括数据处理与特征工程工具、算法分析工具、可视化效果工具,以及EDM和LA的特殊应用,如贝叶斯知识跟踪工具、文本挖掘、社会网络分析、过程与序列挖掘、PSLC服务站等.本文将为初次接触这一领域的研究者提供有用的信息,以帮助他们找到有用的工具.
