大学教师文化的基本特征及教育学意义     

傅定涛 《当代教育论坛》2006,(21):67-68

一、大学教师文化的基本特征1.专业性。大学教师文化的专业性来源于大学教师所从事的工作内容和教师职业本身的专业性。大学教师总是归属于某一学科专业,一生中大部分时间是在某一学科专业领域里从事研究和教学工作,在工作内容上表现出很强的专业性。这是大学教师文化有别于中小学教师文化的重要方面。教师与学生及其他社会成员之间的文化交流更多地是以自己所从事的学科专业为纽带的,这在一定程度上使得大学教师在文化交流上具有某种局限性和自我封闭性。其中既有客观条件的制约,也有主观上的因素,他们往往不愿意或不屑于和别的学科专业的…  相似文献   

符号流中的模式发现     

李刚  童頫 《上海大学学报(英文版)》2001,4(Z1)

The idea of discovering patterns in data seems to be essential for decision making in our social activities. This paper presents a simple algorithm which can be used to detect such patterns in elementary sequences of symbols. It adopts a data compression algorithm to seek for interesting patterns, which is important in understanding the way that the input symbol stream repeats itself. In this paper, the algorithm and related data structures are described in detail, and an illustrative example is given.  相似文献   

Chinese and Canadian Children's Evaluations of Lying and Truth Telling: Similarities and Dfferences in the Context of pro-and Antisocial Behaviors

The present study compared Chinese and Canadian children's moral evaluations of lie and truth telling in situations involving pro- and antisocial behaviors. Seven-, 9-, and 11-year-old Chinese and canadian children were presented 4 brief stories. Two stories involved a child who intentionally carried out a good deed, and the other2 stories involved a child who intentionally carried out a bad deed. When story characters were questioned by a teacher as to who had committed the deed, they either lied or told the truth. Children were asked to evaluate the story characters' deeds and their verbal statements. Overall, Chinese children rated truth telling less positively and lie telling more positively in prosocial settings than Canadian children, indicating that the emphasis on self-effacement and modesty in Chinese culture overrides Chinese children's evaluations of lying in some situations. Both Chinese and canadian children rated trugh telling positively and lie telling negatively in antisocial situations, reflecting the emphasis in both cultures on the distinction between misdeed and truth/lie telling. The findings of the present study suggest that, in the realm of lying and truth telling, a close relation between sociocultural practices and moral judgment exists. Specific social and cultural norms have an impact on children's developing moral judgments, which in turn, are modified by age and experience in a particular culture.  相似文献   

Numerical investigation of cavitating flow behind the cone of a poppet valve in water hydraulic system   总被引：2，自引：0，他引：2

Computational Fluid Dynamics (CFD) simulations of cavitating flow through water hydraulic poppet valves were performed using advanced RNGk-epsilon turbulence model. The flow was turbulent, incompressible and unsteady, for Reynolds numbers greater than 43000. The working fluid was water, and the structure of the valve was simplified as a two dimensional axisymmetric geometrical model. Flow field visualization was numerically achieved. The effects of inlet velocity, outlet pressure, opening size as well as poppet angle on cavitation intensity in the poppet valve were numerically investigated. Experimental flow visualization was conducted to capture cavitation images near the orifice in the poppet valve with 30° poppet angle using high speed video camera. The binary cavitating flow field distribution obtained from digital processing of the original cavitation image showed a good agreement with the numerical result.
