The Issue of Range Restriction in Bookmark Standard Setting

This article uses data from a large‐scale assessment program to illustrate the potential issue of range restriction with the Bookmark method in the context of trying to set cut scores to closely align with a set of college and career readiness benchmarks. Analyses indicated that range restriction issues existed across different response probability (RP) values and item response theory (IRT) models if one were to apply the Bookmark procedure using intact test forms. Results also suggested that range restriction may still be present if one had access to additional data from an item bank. This demonstration critically highlights challenges that may exist in some practical applications of the Bookmark method due items not being designed to cover the full range of examinee abilities.     

A Critical Look into the Beuk Standard-Setting Method

One commonly used compromise standard-setting method is the Beuk (1984) method. A key assumption of the Beuk method is that the emphasis given to the pass rate and the percent correct ratings should be proportional to the extent that the panelists agree on their ratings. However, whether the slope of Beuk line reflects the emphasis that panelists believe should be assigned to the pass rate and the percentage correct ratings has not be fully tested. In this article, I evaluate this critical assumption of the Beuk method by asking panelists to assign importance weights to their percentage correct and pass rate judgments. I show that in several cases that the emphasis suggested by the Beuk slope is noticeably different from what one would expect and is inconsistent with importance weight ratings. I also suggest two ways that the importance weights can be used to calculate alternate cut scores, and I show that one of the ways of calculating cut scores using the importance weights leads to larger potential differences in cut score estimates. I suggest that practitioners should consider collecting importance weights when the Beuk method is used for determining cut scores.     

档案记录方式和载体形式对档案管理工作的影响——实体档案与电子档案管理刍议

当今,现代信息技术对传统实体档案管理产生了深远影响,如何做好实体档案与电子档案管理,笔者认为:首先要厘清实体档案管理的历史发展及其特征;其次要弄清档案馆(室)在实体档案保护与信息化管理中的角色定位;三是档案馆(室)应在实体档案管理与信息化管理交互并存中赢得主动。任何一个时期的档案记录与管理方式,都与人类文明和技术进步相适应,电子档案同样是档案存在的一种形态,同实体档案还有一个长期并存的过程。因此,我们对实体档案不能轻易言弃,而要注重把信息技术运用到不同形态的档案管理中,确保实体档案安全和信息化条件下档案事业发展。     

“我心目中的好课堂”——来自孩子心灵的呼声

对于什么样的＂课＂是＂好课＂,历来有多种说法,可谓仁者见仁,智者见智。然而,这些所谓＂好课标准＂都是成人所构建的。课堂生活是孩子们经历最多、体验最深的一种生活方式。教育现象学研究要求关注教育情境中师生的＂生活体验（世界）＂,关注教育的实际发生领域,关注生活的意义。由此,本研究旨在用教育现象学的方式倾听孩子们内心的声音,用描述性的语言勾勒出孩子们心目中的＂好课堂＂。     

Components of Variance of Scales With a Bifactor Subscale Structure From Two Calculations of α

Since Cronbach's (1951) elaboration of α from its introduction by Guttman (1945), this coefficient has become ubiquitous in characterizing assessment instruments in education, psychology, and other social sciences. Also ubiquitous are caveats on the calculation and interpretation of this coefficient. This article summarizes a recent contribution (Andrich, 2015) on the use of coefficient α which complements these many caveats. It shows that in the presence of a simple bifactor structure of a scale where unique components of variance are homogeneous in magnitude, three components of variance and the common latent common correlation among the subscales can be calculated from the ratio of two calculations of α, one at the level of the items, the other at the level of the subscales. It was suggested that these two ready calculations and their interpretation, and the reporting of all four indices in the analysis of scales with a subscale structure, would reduce the misinterpretation of this coefficient. An illustrative example of the application of the calculations is also shown.
