Perceived Parental Influence on Mathematics Learning: A Comparison Among Students in China and Australia     

Zhongjun Cao  Alan Bishop  Helen Forgasz 《Educational Studies in Mathematics》2007,64(1):85-106

This paper explores the perceived parental influence (PPI) on mathematics learning among over 700 students across three year levels (Years 5, 7, 9) in China and Australia. It was found that the PPI of students was less strong as year levels increased in both countries. Students in China had stronger perceived parental encouragement and higher perceived parental educational expectation than students in Australia. The PPI of students from different home language backgrounds was also investigated. Students in China demonstrated stronger perceived parental encouragement and parental expectation than English speaking students and other language speaking students in Australia, and they also demonstrated stronger perceived parental expectation than Chinese speaking students in Australia, and similar perceived parental encouragement. Within the three groups of students in Australia, Chinese speaking students and other language speaking students demonstrated similar levels of perceived parental encouragement and expectation, but they both demonstrated a higher level of perceived parental encouragement and expectation than English speaking students. Possible reasons for the similarities and differences between the different groups of students were discussed.  相似文献

甲午战争时期中国电报局的作用     

冯超 《安徽教育学院学报》2007,25(5):23-28

电报局是洋务运动中的重要企业,它的创办对近代社会的发展有重要作用。甲午战争时期,从朝鲜战场到国内战场,中国电报局承担了大量不可或缺的事务,尤其是电报局通过架设随军电报直接参与战斗,为清军提供了诸多有利条件。当然,电报局的作用发挥也受到当时时代社会条件的限制,如清廷财力的匮乏,使得战时电报局的建设颇受影响。此外,战事的不利也使电报局遭受人、财、物三方面的重大损失。  相似文献

An adaptive strategy for controlling chaotic system     

曹一家  张红先 《浙江大学学报(A卷英文版)》2003,4(3):258-263

This paper presents an adaptive strategy for controlling chaotic systems. By employing the phase space reconstruction technique in nonlinear dynamical systems theory, the proposed strategy transforms the nonlinear system into canonical form, and employs a nonlinear observer to estimate the uncertainties and disturbances of the nonlinear system, and then establishes a state-error-like feedback law. The developed control scheme allows chaos control in spite of modeling errors and parametric variations. The effectiveness of the proposed approach has been demonstrated through its applications to two well-known chaotic systems: Duffing oscillator and Rössler chaos.  相似文献
