幼儿对死亡概念认知特点的研究

死亡概念是生命科学领域内一个非常重要的科学概念。本研究选取100名3-6岁的幼儿作为被试,采用个别访谈法对幼儿死亡概念认知的特点进行了考察。结果表明:(1)幼儿对死亡概念认知的年龄主效应显著、性别主效应不显著。(2)幼儿对死亡概念的内涵有一定认知,但是同时这种认知还不太成熟。其中,对死亡的适用性和死亡无功能性认知较高,对死亡的不可逆性认知居中,对死亡的普遍性和死亡原因性认知较低。(3)在三类生命体死亡概念的认知中,对动物死亡和人体死亡概念认知要高于对植物死亡概念的认知。     

幼儿情绪认知能力发展特点的研究

本研究采用面部表情辨别和实际情境下的情绪认知两种实验任务测查了95名3～5岁幼儿的情绪认知能力。结果表明：（1）幼儿的情绪认知能力存在显著的年龄差异，随着年龄的增长而增长，但每种具体情绪的发展模式不同；（2）幼儿的情绪认知能力不存在显著的性别差异。     

大班幼儿对交往相关概念认知的实证研究

采用访谈法对80名5-6岁的大班幼儿进行交往概念认知研究,确定幼儿对10个交往相关概念的理解有4个水平,8种类型。研究结果显示,50%以上的幼儿对“礼貌、耐心、礼貌用语、倾听、友好、尊重、自信、换位思考”8个概念的认知处于水平一(对概念缺乏理解);城市和农村幼儿对“礼貌、耐心、礼貌用语、尊重”4个概念的认知存在极其显著性差异,对“合作”概念的认知存在显著差异;留守幼儿与非留守幼儿对“礼貌、礼貌用语、尊重”3个概念的认知存在极其显著性差异;男女幼儿对交往相关概念的认知不存在显著差异。据此,对幼儿交往能力的培养提出相关建议。     

关于幼儿认知死亡的个案研究

对幼儿来说，理解死亡及濒临死亡的概念是比较困难的，虽然我们可以对幼儿认知死亡的过程划分出一个相对明显的阶段，但由于家庭态度、生活经验等因素的影响，不同幼儿认知死亡体现出远比“阶段”更为复杂的特征。     

阈下积极情绪启动对旁观者效应的影响

通过情境启动和阈下情绪启动,对福建师范大学44名本科生进行实验研究,旨在分析阈下积极情绪对旁观者效应的影响。实验采用两因素完全随机设计,组别为群体组和个人组,情绪变量为阈下积极情绪组和控制组,因变量为被试的捐助水平。结果表明：（1）情绪的主效应不显著;（2）组别的主效应显著,群体组的捐助水平显著低于个人组;（3）情绪和组别的交互效应不显著。     

3～5岁幼儿数概念的发展

从给物说数、比较多少、圆点排序和选序数4个方面探查30名3~5岁的幼儿数概念（包括基数和序数）的发展。研究结果表明：（1）幼儿对数概念的掌握随年龄增长而提高,其中4~5岁是幼儿数概念发展的关键期;（2）幼儿对基数和序数的掌握显示出不同的发展速度,基数发展在先;（3）幼儿数概念的发展不存在性别差异。     

幼儿对“衰老”认知的个案分析

衰老是许多病理、生理和心理过程的综合作用的必然结果。在真人秀节目《爸爸去哪儿》中出现的"父母变老测试"的情节设计提供了幼儿对父母衰老认知的个案,通过对个案的分析发现,幼儿对"衰老"具有恐惧心理、对"衰老"概念无法正确认知、对"衰老"与"死亡"概念容易混淆。面对此问题,幼儿家长和教师应珍视幼儿的生命哲学,遵循幼儿认知发展规律,帮助幼儿正确认知生命概念,正确对待"衰老"现象。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
