从公平看我国高校收费政策     

高宇 《四川职业技术学院学报》2006,16(1):71-73

80年代末我国高等教育开始实行招生收费制度改革。本文从政策影响、政策事实和政策价值方面对我国高校收费政策进行分析,认为现有收费水平偏高,对教育公平产生了消极影响。教育公平是社会和谐发展重要基石,教育政策的首选价值应是教育公平。  相似文献

纯电动汽车市场化的成本障碍与产业发展对策     

李哲  卢兰光  欧阳明高 《徐州师范大学学报(哲学社会科学版)》2011,37(1):155-158

通过某款2.0L排量燃油汽车纯电动化后所需的成本构成计算,该电动汽车将比原燃油车成本上升10万元左右,而成本过高必将阻碍其大规模市场化。以下三种途径能够削弱高成本带来的发展障碍:通过车辆微型化能够大幅削减电动汽车成本且同时满足城镇日常出行需要;国家对电动汽车进行财政补贴并推广公共领域示范运营,将加快其技术进步与产业发展;电池租赁能够减少消费者的初始购置成本,是一种发展前景较好的新型商业模式。  相似文献

Differential effects of norm-referenced and self-referenced feedback on performance expectancies,attributions, and motivation     

Wendy McColskey  Mark R. Leary 《Contemporary educational psychology》1985,10(3):275-284

When feedback is provided to students in a norm-referenced manner that compares the individual's performance to that of others, people who perform poorly tend to attribute their failures to lack of ability, expect to perform poorly in the future, and demonstrate decreased motivation on subsequent tasks. The present study examined the hypothesis that the deleterious effects of failure might be attenuated when failure is expressed in self-referenced terms—relative to the individual's known level of ability as assessed by other measures. In this study, subjects received feedback indicating that they did well or poorly on an anagram test, and this feedback was described as either norm-referenced (comparing the individual's performance to that of others) or as self-referenced (comparing performance to other measures of the individual's ability). As predicted, compared to norm-referenced failure, self referenced feedback resulted in higher expectancies regarding future performance and increased attributions to effort. Contrary to expectations, attributions to ability were not affected. The implications of the results for the structure of academic feedback are discussed.  相似文献   

Attributions in a mastery instructional system: Is an emphasis on effort harmful?     

Mark Grabe 《Contemporary educational psychology》1985,10(2):113-126

Self-worth theorists have claimed that students of lower ability may reduce effort in likely failure situations to avoid the attribution of poor performance to their own incompetence. The likely success of mastery learning, an instructional technique stressing student persistence, has been questioned because of this phenomenon. Several studies which examined the hypothesized relationship between achievement, effort, and perceived ability within a mastery context were conducted. In none of the studies did it appear that students reduced effort because of the threat of failure or that expending effort led to lower estimates of ability. In fact, students expending effort rated their ability as having a more positive influence on performance than less persistent students. It is argued that mastery learning, like some achievement change programs, encourages students to attribute their performance to their level of effort.  相似文献
