导师制对研究型本科生毕业设计质量的影响

毕业设计是本科教学中最重要的环节之一,是检验大学生所学知识的重要手段,是理论知识结合实际的一种重要方法,也是培养学生实际动手能力和初步科研能力、独立工作能力以及增强创新意识的重要途径。对于有意向继续深造的本科生,采用导师制的方法来提高研究型本科生毕业设计的质量,切实提升学生的个人素质,为继续深造打下坚实的基础。     

经典测量理论与项目反应理论的比较研究

文章通过对经典测量理论和项目反应理论的模型及其假设、主要概念和参数、测量水平等方面进行比较,廓清了两种理论的联系和区别,明确了两种理论的优势和不足,从而为研究者根据测验实践的要求和各个理论的适用条件选择恰当的分析框架提供思路。     

Diversity in the Information Seeking Behaviour of the Virtual Scholar: Institutional Comparisons

The logs of four universities using the OhioLINK journal system were evaluated for a period of fifteen months using deep log analysis methods in order to compare and contrast the information seeking behaviour of their users. Large differences were found, especially between the research and teaching universities. Methodological problems associated with making the comparisons are discussed in some detail especially in terms of defining online sessions.     

Heisenberg and ferromagnetism

Heisenberg’s contributions to the understanding of ferromagnetism are reviewed. The special features of ferromagnetism, vis-a-vis dia and para magnetism, are introduced and the necessity of a Weiss molecular field is explained. It is shown how Heisenberg identified the quantum mechanical exchange interaction, which first appeared in the context of chemical bonding, to be the essential agency, contributing to the co-operative ordering process in ferromagnetism.
