Characterization of an Ordinary Teaching Practice with the Help of the Theory of Didactic Situations

In this paper, we use the theory of didactic situations to characterize a mathematics teaching practice, currently used in secondary schools in France, which we have called interactive synthesis discussion. We have studied this practice in ordinary classes, i.e. classes where the researcher intervenes neither in the preparation nor in the management of the lessons. We have looked at the didactic situations the teacher chooses, and how he manages his teaching project, the students’ work in the classroom and at home, and classroom interactions. We present two case studies of experienced teachers, one in grade 8, and the other in grade 10.     

论中国古代契约的身份特点

中国古代很早即有契约,但契约主体的自由意志受到扼制以至泯灭。中国古代一直缺乏现代契约精神;古代契约不是自由意志的结果,反而表现出浓厚的身份性。本文通过对古代契约身份特点的分析,希望人们正确认识古代契约制度。在现代市场经济条件下,为弘扬现代契约精神,在中国需要来一次真正的从身份到契约的运动。     

试论高校校长选拔体制的改革

高校校长选拔体制沿用党政干部选拔体制的做法,没有体现出高校作为高级人才培养和知识创造机构的固有特征,难以使高校成为教育家们实现教育理想的舞台。阻碍教育家们进入高校领导领域的主要原因,是人们对于高校性质、宗旨及职责的模糊或浅显认识。以聘任制代替任命制,既不会违背党管干部的原则,又是高校校长成为教育家的理想途径。

市场经济、“法治社会”与中国特色“契约文化”建设

市场经济的发展,内在吁求并必然孕育、催生出一个与之相适应的法治社会--一个以契约、自治等为鲜明特质的高度理性化的"市民社会".市民社会的原生秩序是以契约性关系为网络的.中国社会近几年市场经济发展的现实表明,以自由交换、自由权力与自组织行为为基本标志的中国特色"市民社会"的契约化过程已经实实在在地得以发生和开始."契约文化"是市场经济社会文化精神的血脉,包孕了独立人格、自由个性、权利平等、科学理性、民主法治、社会责任感等丰富的内涵.社会主义市场经济条件下的"契约文化",本质上是实现人的解放和全面发展的文化.市民社会的"契约文化"理念的确立与市民社会成员"公民意识"的培育不可分割,这是现代文化观念所奉行的人性自主、自律的深层要求之所在.     

Can software improve marker accuracy at detecting contract cheating? A pilot study of the Turnitin authorship investigate alpha

Abstract

Contract cheating happens when students outsource their assessed work to a third party. One approach that has been suggested for improving contract cheating detection is comparing students’ assignment submissions with their previous work, the rationale being that changes in style may indicate a piece of work has been written by somebody else. This approach is time consuming, but recent advances in machine learning and natural language processing suggest that it may be well suited to computerization. We trialed an early alpha version of Turnitin’s Authorship Investigate tool, which compares students’ submissions against their previous work. Twenty-four experienced markers from five units of study were asked to make decisions about the presence of contract cheating in bundles of 20 student assignments, which included 14 legitimate assignments and six purchased from contract cheating sites. We asked markers to determine if each assignment was contract cheating, then provided them with an Authorship Investigate report and let them change their decision. Marker accuracy at detecting contract cheating increased significantly, from 48% to 59% after using the report, with no significant difference in false positives. These findings suggest that software may be an effective component of institutional strategies to address contract cheating.
