绩效考评与平衡计分卡

平衡计分卡作为战略绩效管理及评价工具,强调从财务、客户、内部流程以及学习与成长四个不同视角来衡量一个企业,四项指标的驱动关系有效地保证了组织战略的实现。平衡积分卡产生于西方完全市场化经济环境下,在中国的实施中受到了一定的限制。分步走,即先在组织或战略层面,然后在员工层面实施,是BSC的应用思路。作者的建议是将边际思想与平衡计分卡相结合,即边际平衡计分卡。BSC的发展趋势是个性化、个体化与复合型。它的有效实施还赖于充分的沟通。

History as performance: pupil perspectives on history in the age of ‘pressure to perform’

The development a standard-based curriculum in History can be related to the school reforms where ‘performance’ are crucial principles. The aim is to analyse pupils’ perspectives on the relation between their views on historical knowledge and the national test in History and grading. When the pupils in this study – directly after taking a national test in History – were asked to reason about what historical knowledge is, another subject emerged: a collective memory subject. History as ‘performance’ emerges clearly in connection with the pupils’ discourse on grades and History, which has an emphasis on ‘working’, ‘writing’, and ‘doing homework’ to get a better grade in History. The disciplinary knowledge content specified in the curricula does not correspond to pupils’ experiences of what the central historical knowledge is in national tests and grading. It is apparent that disciplinary knowledge content is ‘under pressure’ in the age of performance.     

Effects of curricular emphasis in college on the GRE and its impact on the gender gap in performance

Previous research has indicated positive relations between a curricular emphasis during college and improvements in GRE performance for content that matches that emphasis. However, measurement issues and a lack of a theoretical approach have contributed to a lack of precision and detail in the estimates of the relation between college experiences and performance for relevant content. In the current study, we hypothesized that differences in training between students majoring in math related majors and students majoring in reading and writing related majors would be differentially related to the size of the changes on GRE performance. Further, we hypothesized the gender gap in GRE-Quant performance would be reduced when the higher likelihood of males majoring in math related majors was modelled. The expert performance approach was used to develop three path models (including curricular emphasis, college grade performance, previous performance on the SAT, and gender) to compare the effects of the relation of a curricular emphasis in math on GRE-Quant performance to the effects of the relation of an emphasis in reading and writing on GRE-Verbal performance. The results indicated support for our predictions that a math course emphasis was related to larger GRE performance gains and that gender differences in curricular emphasis during college partially mediated the large gender gap in GRE-Quant performance. Additionally, higher grade performance average was found to positively predict GRE performance with college experiences and previous performance statistically controlled. Implications for the relation between training accrued during college courses and changes in GRE performance are discussed.
