小学生数学学习观:结构与特点的研究

采用问卷法,本研究探讨了小学生数学学习观的结构与表现特点。研究表明:小学生数学学习观的四个因素,即数学学习兴趣、课堂参与性、数学学科观与数学交流的素养,能够较好地解释数学学习观的心理结构;小学生的数学学习兴趣与课堂参与性,随着年级升高显著下降,而在数学学科观与数学交流的素养方面则表现出相反的趋势,即随着年级升高而提升;男生的学习兴趣与课堂参与性明显高于女生,但在数学学科观与数学交流的素养方面,女生则明显好于男生。     

不同问题情景对小学生运用乘法运算策略的影响

通过设置不同问题情景引导被试利用乘法运算定律解决数学问题,探讨不同问题情景对小学四、六年级学生运用乘法运算策略的影响。结果表明:(1)被试掌握交换律的情况均好于分配律;即使没有正式学过交换律,四年级被试使用交换律的成绩与六年级被试没有显著差异。(2)六年级被试在同形问题情景中利用分配律线索的成绩好于其它的问题情景,两个年级后进生同形问题的成绩均好于其它问题情景。总体而言,相对于面积问题情景和笛卡尔积问题情景,同形问题表征方式更有利于小学生利用乘法运算策略。     

小学教师科学素养的调查研究

为了解大连地区小学教师科学素养的现状,采用自编调查问卷对265名大连市城乡小学教师进行了调查研究。结果表明:1)本、专科学历小学教师的科学素养明显高于中专学历的教师;2)小学教师较好地掌握了小学水平的科学知识,但对中学以上水平的科学知识掌握较差;3)教师的科学素养水平没有表现出随教龄的增长而提高。     

小学教师课堂信息加工能力的研究

研究采用小学语文和数学教学录像为实验材料,以98名小学语文数学教师、其他学科教师和非教师为研究对象,运用反应时测量法探讨小学教师加工不同类型课堂信息的速度和辨别能力。结果表明:有学科教学经验的教师(语文和数学教师)在重视学科教学内容的同时,也重视课堂教学活动的组织和课堂气氛的调节;学科知识、学科教学经验和课堂教学经验对教师的课堂信息加工能力和教学专长发展有显著的影响;研究结论对提高教师课堂教学能力、教学专长以及教师培训提供了有力的实验证据。     

获得性阅读障碍的“主要系统”假说

认知神经心理学为阅读机制的探讨提供了大量的证据,认为不同阅读障碍是不同加工通道选择性受损的结果。近年来,基于联结主义的三角模型理论,研究者提出了主要系统假说（primary system hypothesis）,认为阅读障碍是主要的认知系统（如视觉、语义和语音系统）受损导致的：表层障碍是因为语义系统受损导致的阅读困难,语音和深层障碍是语音和语义系统同时受损时综合症状的连续体。该理论认为各主要系统可能同时是多个认知活动的加工成分,一个系统的受损会影响所有与之相关的认知过程,从而把阅读障碍与其它认知功能障碍联系起来。统一的主要系统受损下对各种获得性阅读障碍形成机制在文中得到详细的解释     

Tolerance as a Primary Virtue

The commonly perceived tension between authentic moral and ethical action and action involving tolerance is held to be the illusory product of an unduly individualistic frame of thought. Moral and ethical actions are produced not by independent individuals but by participants in cultural traditions. And even the wholly routine continuation of a single homogeneous tradition must always and invariably involve mutual tolerance: participants must interact not as independent individuals but as tolerant members. Tolerance deserves recognition, accordingly, as a primary virtue, not merely compatible with authentic moral and ethical action, but required by it. An explicit rhetoric enjoining tolerance needs to be understood as performative discourse employed to change, or else to sustain, the systems of tolerances in which all cultures, whether simple or differentiated, homogeneous or diverse, unified or fragmented, invariably consist.

Aggressive content and related defenses in Rorschach responses of children ages 6–14

The aim of this study was to test the psychoanalytic notion that there is a gradual progression with age from primary to secondary process thinking. Three cohorts of children, age 6, 9, and 12, were administered the Rorschach procedure at yearly intervals—twice for the oldest cohort and three times for the two younger ones. No support was found for the developmental hypothesis in terms of aggressive content of the responses and the related defenses. The expectation of more aggressive content at earlier ages, as a reflection of more primitive aggressive drives, was not confirmed.     

Primary care decision making in response to psychological complaints: the influence of patient race

Eighteen general practitioners indicated diagnostic and treatment decisions in response to patient vignettes. Results indicated that White patients were more likely to be correctly diagnosed as having anxiety than any other complaint. Asians were just as likely to receive a physical diagnosis as they were to receive one of anxiety. Copyright © 2000 John Wiley & Sons, Ltd.     

3至6岁幼儿心理压力源与表现

本研究在大量的调查、访谈和问卷分析的基础上,提出了有关幼儿心理压力的问题,并对幼儿心理压力的来源和表现进行了深入细致的调查和分析。结果发现,幼儿身边存在很多压力事件;幼儿的心理压力主要来源于6个方面:父母、老师、环境适应、同伴关系、功课学习和其他;幼儿的心理压力主要表现在四个方面:生理上的反应、行为上的反常、情绪上的变化和个性上的改变。     

The Effect of Racial and Ethnic Diversity on the Delivery of Mental Health Services in Pediatric Primary Care

The effects of racial and ethnic diversity on the detection and management of behavioral and emotional problems in pediatric primary care are addressed. Service access and utilization as a function of race and culture are initially examined. Important barriers within pediatric training including minimal emphases on behavioral training and the limited supply of minority physicians are underscored. The impact of ethnicity on the development and maintenance of the clinical relationship that is critical to accurately and sensitively identifying and managing behavioral and developmental problems is briefly addressed. Recommendations for further integration of racial/ethnic issues into mental health service provision within the pediatric primary care arena are presented.
