An investigation of the psychometric evidence of CBM-R passage equivalence: Utility of readability statistics and equating for alternate forms

Claims have been made that grade appropriate curriculum-based measurement of reading (CBM-R) passages are of comparable difficulty and can be used interchangeably to monitor student progress. Empirical evidence to support claims of equivalence has been lacking. This research investigated the basis for making claims of equivalence. The use of readability statistics to justify passage equivalence was found to be lacking. Using a general measurement model for congeneric tests, CBM-R passages were found to measure a single latent factor with a high degree of reliability. However, evidence indicated that the raw scores, words read correctly per minute, across passages did not provide equivalent measurements. Statistical equating was investigated as an approach to overcome the lack of equivalence with promising results.     

A preliminary investigation of within-year growth patterns in reading and mathematics curriculum-based measures

This study examined patterns of growth across benchmark assessments for curriculum-based measures (CBM) over 2 academic years, with the twofold purpose of replicating earlier findings of growth patterns on R-CBM and conducting a preliminary investigation of growth patterns on M-CBM and CBM-Maze. The sample included 898 cases from 3rd through 5th grade over 2 academic years from one elementary school in the rural Midwest. All students participated in tri-annual benchmark assessments in which they were administered R-CBM, CBM-Maze, and M-CBM. Repeated measures analysis of variance was used to examine patterns of growth for all three measures. Students demonstrated greater R-CBM weekly growth during winter-to-spring than fall-to-winter across grade levels. Patterns for CBM-Maze and M-CBM were somewhat inconsistent across school years and grade levels. Results are discussed in terms of contextual variables that may impact within-year growth patterns and technical characteristics of CBM slopes.     

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

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). The author would like to thank an Associate Editor and two anonymous referees and also Professor H.H. Schulze for their very valuable suggestions and corrections.     

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。
