中小学生认知能力发展水平测验的研究

以皮亚杰的认知发展理论为基础,采用皮亚杰及其学生研究认知发展时的任务为测验题目,编制成测量中小学生认知能力发展水平的测验.通过对2240名中小学生施测,结果表明本测验不仅具有很好的信度和效度,而且也具有适中的难度.然后以一所中学特长班学生为被试,通过对他们进行测量,并将测验结果与同年级普通班学生的认知成绩进行比较,结果存在很明显的差异.最后对中小学生认知能力发展水平测量问题进行了探讨.     

Toward a Comprehensive Strategy for Effective Practitioner–Scientist Partnerships and Larger-Scale Community Health and Well-Being

This article articulates joint priorities for the fields of prevention science and community psychology. These priorities are intended to address issues raised by the frequent observation of natural tensions between community practitioners and scientists. The first priority is to expand the knowledge base on practitioner–scientist partnerships, particularly on factors associated with positive outcomes within communities. To further articulate this priority, the paper first discusses the rapid growth in community-based partnerships and the emergent research on them. Next described is an illustrative research project on a partnership model that links state university extension and public school delivery systems. The article then turns to the second, related priority of future capacity-building for diffusion of effective partnership-based interventions to achieve larger-scale health and well-being across communities. It outlines two salient tasks: clarification of a conceptual framework and the formulation of a comprehensive capacity-building strategy for diffusion. The comprehensive strategy would require careful attention to the expansion of networks of effective partnerships, partnership-based research agendas, and requisite policy-making.     

师生关系与中小学生学校适应性的关系

师生关系作为儿童人际关系的一部分,是儿童社会化的重要内容,对儿童的学校适应产生重要影响。本研究运用问卷法、访谈法等对6个年级867名中小学生进行测查,以了解中小学生师生关系对学生学校适应性的影响。结果表明:(1)中小学生学校适应性与师生关系之间存在显著正相关;(2)师生关系是影响学生学校适应性的重要因素。其影响程度从大到小依次为:亲密性、主动性、合作性;年龄也影响学生的学校适应性,但程度较小。     

Individual Accountability in Cooperative Learning Groups at the College Level: Differential Effects on High,Average, and Low Exam Performers

Over a three-semester period in a large undergraduate human development course, students were assigned to 5–7 member groups to work together in preparing for an exam in one of the five content units in the course. Their exam performance was tracked over three units: a baseline unit in which students worked only individually, a unit in which they worked in cooperative teams, and a follow-up unit in which the formal cooperative team structure was removed. Three different bonus-credit contingencies were used in the cooperative learning unit across the three semesters: (a) awarding full bonus credit to each individual in the group if the group as a whole improved its exam performance by the specified amount, (b) awarding partial bonus credit to each individual in the group if the group as a whole improved it exam performance by the specified amount and full bonus credit to each individual who also improved by the specified amount, and (c) awarding full bonus credit to an individual in the group if both the group and the individual improved exam performance by the specified amount. The three contingencies produced somewhat similar patterns of change for low and average performers, but the high performers fared better under the last two contingencies than under the group-only contingency.     

The relationship of body image dissatisfaction to cigarette smoking in college students

This study examined the association of cigarette smoking status and body image dissatisfaction as measured by the Multidimensional Body-Self Relations Questionnaire (MBSRQ), in 1575 young adult college students, 18–24 years of age. Respondents were current cigarette smokers (N = 482) or never tobacco users (N = 1093). Smoking status was found to be significantly associated with 5 of the 10 MBSRQ subscales, with current smokers having lower scores on Fitness Orientation, Health Evaluation and Health Orientation (all p < 0.001) and higher scores on Appearance Orientation (p = 0.01) and Overweight Preoccupation (p = 0.03) compared with never tobacco users. Furthermore, among current smokers, a higher number of days smoked in the last 30 days were associated with lower scores on all MBSRQ subscales, except Self-Classified Weight. In terms of clinical implications, interventions for smoking cessation among college students might benefit from inclusion of components for addressing body image dissatisfaction and improving health beliefs.     

小学生心理素质与学业成绩的关系

运用《瑞文标准推理测验》和自编的《小学生心理素质问卷》对1247名小学生作心理素质团体测试。利用方差分析和聚类分析,探讨小学生心理素质与学业成绩的关系。结果表明:(1)总体上,学业成绩高分组心理素质优于学业成绩中等组和低分组,学业成绩中等组优于学业成绩低分组。(2)分年级看,不同年级不同学业成绩组的小学生在心理素质因素上的差异有不同。(3)学业成绩高分组学生主要分布在心理素质较好的水平层次,学业成绩中等组主要分布在心理素质中等水平层次上,而学业成绩低分组主要分布在心理素质不好的水平层次。     

初中生认同的亲社会行为的初步研究

通过对8名11～14岁初中生的深入访谈,初步探讨了处于初中阶段的青少年认同的亲社会行为。发现:(1)初中生最认同的亲社会行为是帮助行为,其次是交往行为。此外,安慰行为、公益行为、礼貌行为和遵规行为也被他们认同;(2)初中生对不同行为主体间发生的亲社会行为的认同有明显差异,他们更关心发生在他们之间的亲社会行为;(3)普通学校、打工子弟学校的初中生对帮助行为和交往行为认同的比率差异明显;(4)初中生认同的亲社会行为的种类不存在明显的性别差异。     

Noncontingent reinforcement, alternative reinforcement, and the matching law: a laboratory demonstration

Basic researchers, but not most applied researchers, have assumed that the behavior-decelerating effects of noncontingent reinforcement result at least partly from adventitious reinforcement of competing behaviors. The literature contains only sketchy evidence of these effects because few noncontingent reinforcement studies measure alternative behaviors. A laboratory model is presented in which concurrent schedules of contingent reinforcement were used to establish a "target" and an "alternative" behavior. Imposing noncontingent reinforcement decreased target behavior rates and increased alternative behavior rates, outcomes that were well described by the standard quantitative account of alternative reinforcement, the generalized matching law. These results suggest that adventitious reinforcement of alternative behaviors can occur during noncontingent reinforcement interventions, although the range of conditions under which this occurs remains to be determined in future studies. As an adjunct to applied studies, laboratory models permit easy measurement of alternative behaviors and parametric manipulations needed to answer many research questions.     

Government Subsidized Academic Research: Economic and Ethical Conflicts

Justification for public funding of academic research is based on the linear model of technological advance first proposed by Francis Bacon. The model hypothesizes that government subsidized science generates new technology which creates new wealth. Mainstream economics supports Bacons model by arguing that academic research is a public good. The Bayh–Dole Act allows universities to privatize federally funded research and development (R&D) which is in direct conflict with the public good argument. Diminishing returns to university R&D, challenges to Bacons linear model and the labor exploitation of young scientists by research universities suggest that policy makers may want to reconsider the system for allocating federal R&D to universities and colleges.     

Perceptions of Ethical Behaviour among Business Faculty in Canada

Faculty members at Canadian business schools were surveyed regarding their ethical perceptions of behaviours related to undergraduate instruction. Fifty-five behavioural statements were listed and respondents were asked to rate the extent to which they felt each behaviour was ethical or unethical. The only item that respondents endorsed as unequivocally unethical (90% indicated it was definitely unethical) was Becoming sexually involved with an undergraduate in one of your classes. We also compared the results of our sample to those of an American sample. Overall, an interesting pattern of differences emerged between the responses obtained in Canada and the U.S. In general, the direction of the significant differences was such that Canadian professors viewed the behaviours in question as less ethical than did their American counterparts.
