计算机化多阶段自适应测验研究述评

摘 要 计算机化多阶段自适应测验是基于计算机技术的测验形式,它将题目集合作为测试单元,通过多阶段自适应的形式对被试进行测试和评分。近年来通过研究各种测验形式,发现其比计算机化自适应测验和传统纸笔测验突显出更大优势。与传统纸笔测验相比,其具有参数不变性、能力估计更精确等优势。与计算机化自适应测验相比,其具有可控制题目特性、被试可检查题目等优势。如何减小测量误差,使其应用更加便捷、有效,是未来研究的发展方向。     

不同认知结构被试的测验设计模式

正如不同的病症需要使用不同的医疗技术方法来诊断一样, 不同的认知结构也需要设计对应的测验模式来进行诊断, 从而保证测验具有高质量的诊断评估效果。但传统测验形式未考虑不同认知结构的针对性诊断测验需求, 导致“千人一卷”在测验效率上有所不足; 认知诊断计算机化自适应测验虽可针对不同认知结构的被试施测不同的项目, 然而支持自适应过程的题库却没有针对不同认知结构被试设计对应的项目, 导致题库使用效率较低。要解决上述问题的关键在于, 探索如何针对不同认知结构设计相对应的测验模式。本研究采用Monte Carlo模拟, 对六种属性层级关系下, 不同认知结构的测验设计模式进行探讨。实验结果表明(1)同一属性层级关系下, 不同认知结构的最佳测验设计模式不同; (2)依据不同认知结构的最佳测验设计模式构建的题库具有更高的使用效率。测验编制者可以根据实验结果针对不同认知结构优化对应的测验设计模式, 并用于指导题库建设。     

The Swedish National Adult Reading Test (NART-SWE): a test of premorbid IQ

The purpose of this study was to construct a Swedish version of the National Adult Reading Test (NART-SWE), a test for assessment of premorbid IQ, and to investigate its validity and reliability on healthy controls and patients with mild Alzheimer's disease. As Swedish pronunciation rules are fixed, NART-SWE was constructed using loan words. NART-SWE has satisfactory psychometric properties: Inter-rater and retest reliability as well as internal consistency are very high. The NART-SWE demonstrates face validity. In addition, high correlation with IQ was obtained. A significant model emerged when using NART-SWE to predict IQ. Furthermore, no significant differences were observed when comparing performance for healthy controls' with that of patients with Alzheimer's disease on NART-SWE. It does appear that reading of irregular words is intact in mild Alzheimer's disease.     

Adolescent coping scales: a critical psychometric review

Individual coping is identified as an important factor in relation to health and well-being. Although several coping scales have been developed, key terms of coping such as nature and a number of primary and secondary factors (dimensions) are obscure. Coping scales, such as those that have been developed through exploratory factor analysis (EFA), have been criticized for poor psychometric properties, yet the critique so far does not evaluate development of the scales against best test-theoretical practice. The present study reviews six adolescent coping scales against ten detailed psychometric criteria in relation to statistical choices throughout the process of scale development. All six scales measured poorly on several criteria. Best practice had not been followed throughout their development and they suffered serious psychometric limitations. These findings indicate that there still is empirical research to be pursued in search of latent constructs and possible dimensions of coping through the implementation of EFA.     

书院诚信教育简析

古代书院非常重视生徒的诚信教育.书院教育家认为"诚"既是"天之道",又是"人事之本然",故教育生徒要保持人的"诚"之本质,进而坚守"言行相顾"之"信",担负于他人、社会之责任.     

Neophilia in domestic dogs (Canis familiaris) and its implication for studies of dog cognition

This study examined novel-object preference in dogs. In a free choice test 17 dogs were presented with a novel toy in a line up with two familiar toys. The unfamiliar object was chosen first in 38 out 50 tests suggesting a strong preference for novel over familiar items. Neophilia may be an adaptive trait for domestic dogs that has helped their adaptation towards man.     

Philosophy—what is to be done?

Philosophical thinking, in the historically original sense, is simply the human mind in operation, unaided by anything supernatural and unfettered by any human authority or any procedure for reaching some pre-given end. This means that “philosophy” originally included far more than it does now, including all the natural sciences, as well as rational reflection on society, history, and art. What this means for us now is that philosophy must be an essentially outward-facing discipline, open to others. Most importantly, it needs now to be open to the sciences, to practical social reflection, and to its own history. But what philosophy brings to all its reflections is above all a spirit of critical reflection, respect for evidence and argument, and a ruthless honesty that demands of people that they form their beliefs and views of life according to the best reasons and information they have, rather than forming their views according to their wishes or prejudices, or letting them be dictated by authorities or social traditions. In this sense, we are living in an unphilosophical, or even anti-philosophical, age, but this makes it all the more important for philosophy to continue to do its work.     

医患诚信问题探讨

近些年,诚信缺失现象大量滋生,信用问题日益凸现,医疗行业也深陷其中。医患诚信问题严重地挫伤了医患感情,医患间不信任情绪不断加深。关注和研究我国医患关系中的诚信伦理问题已刻不容缓。     

适应性测验的发展:历史与现状

适应性测验作为一种测验形式,与传统的纸笔测验形式相比,具有省时、高效等很多优越性。测验应该适合于被试的理念最初可见于比内的智力测验。上世纪七十年代以来,适应性测验的研究从经典测量理论阶段发展到项目反应理论阶段,经历了从二阶段、三阶段、多阶段测验、固定分支测验和分层适应性测验的发展,到现在的计算机化适应性测验研究。随着项目反应理论和计算机技术的发展,计算机化适应性测验已经在教育和心理测验领域中得到广泛应用。目前对它的研究日益深入,主要有项目克隆、项目曝光、多维适应性测验、被试诊断、人格适应性测验等问题。
