Performance Indicators in Math: Implications for Brief Experimental Analysis of Academic Performance

Brief experimental analysis (BEA) can be used to specify intervention characteristics that produce positive learning gains for individual students. A key challenge to the use of BEA for intervention planning is the identification of performance indicators (including topography of the skill, measurement characteristics, and decision criteria) that meaningfully relate to longer term success in the learning environment. This study investigates the utility of various curriculum-based assessment and measurement estimates of mathematics performance for predicting functional outcomes (i.e., retention of learned skills over time and faster learning of related content in the future). All children in grades 2–5 at the participating school participated in protocol-based computational fluency-building intervention 4 days per week for an entire school year. Specific criteria were applied each week to systematically increase intervention difficulty classwide according to a pre-established sequence of computational skill objectives. Three measurements were routinely obtained. Each week children completed a timed probe of the skill for which intervention was currently occurring and a timed probe of previously mastered skills from the sequence of computational skill objectives. Each month, all children completed a timed probe of mathematics skills representing computational skills that students were expected to master by year’s end at each grade level. At all grade levels, learning a skill that appeared early in the hierarchy or sequence of skills related positively to learning of future related and more complex computational skills. Fluency criteria were specified that predicted retention of the skill over several months.     

西方心理分离的研究回顾

近几十年来,家庭对儿童青少年心理发展的影响受到众多研究者的关注,国外家庭研究和治疗领域的许多研究者进行了大量有关心理分离的研究。心理分离即个体与家庭在心理上的分离并形成个体化的程度。文章从心理分离的界定、心理分离的理论背景（Mahler发展阶段理论、Bowen家庭系统理论）、心理分离的测量方法、心理分离研究现状这几方面对现有研究进行了综述,并做了简要评述,最后阐述了西方心理分离的研究对我国家庭研究与治疗的启示,并对未来的研究进行了展望     

失败恐惧研究述评

失败恐惧（Fear of Failure,简写为FF）作为一种消极的情绪体验,近年来越来越多地受到研究者的关注。文章主要介绍了失败恐惧概念结构的演变、测量工具由单维到多维的发展过程、失败恐惧特质形成和预防的心理动力学探讨以及多维测量工具在失败恐惧干预方法中的作用。在此基础上,文章对未来研究进行了展望,比如失败恐惧是否存在跨文化、跨领域的差异,我国经济转型时期失败恐惧研究具有怎样的现实意义等     

儿童早期空间非标准测量能力发展研究进展

测量是数学的主题之一。空间非标准测量能力的发展对儿童数学认知能力的发展有重要作用,对儿童思维抽象性、逻辑性、创造性的培养,问题解决能力的提高有重要影响。文章通过对近四十年来儿童空间非标准测量能力发展研究的成果进行概括分析,发现研究者主要对儿童空间非标准测量的认知加工线索,长度测量策略与工具的使用,空间非标准测量知识的获得顺序以及相关的测量教学顺序,空间非标准测量能力与守恒和推理能力的关系等问题进行了研究。并在此基础上提出了儿童空间非标准测量能力发展研究需进一步探讨的问题。     

A Unified Nonparametric IRT Model for <Emphasis Type="Italic">d</Emphasis>-Dimensional Psychological Test Data (<Emphasis Type="Italic">d</Emphasis>-ISOP)

The (univariate) isotonic psychometric (ISOP) model (Scheiblechner, 1995) is a nonparametric IRT model for dichotomous and polytomous (rating scale) psychological test data. A weak subject independence axiom W1 postulates that the subjects are ordered in the same way except for ties (i.e., similarly or isotonically) by all items of a psychological test. A weak item independence axiom W2 postulates that the order of the items is similar for all subjects. Local independence (LI or W3) is assumed in all models. With these axioms, sample-free unidimensional ordinal measurements of items and subjects become feasible. A cancellation axiom (Co) gives, as a result, the additive isotonic psychometric (ADISOP) model and interval scales for subjects and items, and an independence axiom (W4) gives the completely additive isotonic psychometric (CADISOP) model with an interval scale for the response variable (Scheiblechner, 1999). The d-ISOP, d-ADISOP, and d-CADISOP models are generalizations to d-dimensional dependent variables (e.g., speed and accuracy of response).

品牌忠诚：概念、测量和相关因素

早期研究者对品牌忠诚的定义多是操作性的,主要为行为论和态度论观点。将品牌忠诚看作复杂多维度概念,则成为当前研究者广泛接受的观点。品牌忠诚度是对消费者品牌忠诚的测量,依研究目的不同而有多种形式。消费者认知、态度和行为方面的一些变量,和品牌忠诚相互作用。     

网络旗帜广告的记忆效果

由于人们对网络旗帜广告效果的质疑,在网络广告的计费方式上也出现了两种计价模式,分别为按照浏览率和点击率来计量广告效果。其本质问题在于单纯浏览是否能够产生广告效果,以及浏览和点击各自所能带来的广告效果差异有多大。本研究利用模糊测量及相应统计方法,就上网者对网络旗帜广告的记忆效果进行测量。结果显示,在单纯浏览的情况下,上网者对网络旗帜广告已经留有印象,但这种记忆效果并不随着浏览次数的增加而显著改善;点击所能带来的广告记忆效果约为单纯浏览对应效果的1.4~1.5倍     

儿童早期测量能力的发展

测量能力是儿童早期数学认知能力的一个重要方面,其中直接比较和非标准测量能力作为儿童早期测量能力发展的主要形式,在一定程度上代表着儿童早期测量能力的发展。本研究对92名3岁儿童的测量能力进行了为期一年的追踪研究,结果发现:(1)在3~4岁期间,儿童直接比较测量能力和非标准测量能力均得到显著发展,但直接比较测量能力的水平提高得更快;(2)儿童直接比较测量能力的年龄主效应、任务主效应以及年龄和任务的交互效应显著;(3)儿童非标准测量能力的年龄主效应和任务主效应均达到显著水平,非标准测量单位应用能力的水平显著高于非标准测量单位形成能力的水平。     

Assessing the process of desensitization therapy: Five practical measures

Assessment of phobic behavior has included self-report, physiological, and in vivobehavioral measures. While self-report measures are convenient, they suffer from subject bias and a low predictive validity. Physiological and in vivobehavioral measures are often too cumbersome to implement in standard clinical practice. The current study investigated the validity of five convenient measures of phobic behavior during the process of desensitization therapy. Responses of 14 clinically phobic patients were compared on phobic and neutral scenes presented within the context of systematic desensitization therapy. Phobic scenes resulted in less clarity of scene visualization, a longer latency to clear scene visualization, higher subjective units of discomfort (SUDs) at clear visualization, a longer latency to relaxation, and higher SUDs at relaxation. The measures seemed to reflect accurately the process and stages of desensitization therapy and showed low to high intercorrelations. The pragmatic value of these measures is discussed, as well as suggestions for future validational research.     

Measuring grief: A short version of the perinatal grief scale

Despite a considerable number of studies, there are two major drawbacks in the literature on grief and bereavement. One is a lack of adequate and generally agreed upon measures for assessing grief. The second is a lack of ability to predict from existing measures the likelihood of what has been termed chronic or pathological grief reactions. This paper reports the results of the development of a bereavement measure for the study of perinatal loss which attempts to address these gaps. The measure is specific to a pregnancy-related loss, although it has the potential for adaptation to use for other types of loss. Analysis of responses from 138 women has resulted in the reduction of the original measure from 104 to a more manageable and almost equally comprehensive and reliable 33 items. In addition, a factor analysis has produced three factors, two of which indicate the possibility for longer-term and more severe grief reactions. Because of its sound psychometric qualities and interesting factor structure, the measure shows promise of being useful for both research and clinical purposes.This research was funded by National Institute of Child Health and Human Development Grant R01 H18431-04, with additional assistance from the Center for Social Research at Lehigh University.
