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.

普通话水平测试中的说话刍议

在普通话的水平测试和日常应用中，说话都是最主要的部分。许多人在普通话测试中，在说话时存在着过度紧张、无话可说、带“话把”的情况，导致发挥不理想，成绩上不去，而且还会在日常的应用中出现障碍，影响本人各个方面。自我陶冶性格，进行锻炼，合理抑制，互相学习，是解决问题的有效方法。

论不起诉制度下被害人自我救济措施的完善

关于不起诉被害人自我救济制度，各国立法各不相同。从我国立法的规定来看，我国不起诉被害人自我救济制度存在着对申诉机制重视不够、自诉案件范围宽泛、自诉担当制度缺失、证明标准过高等问题，因此，有必要在借鉴其他国家成功经验的基础上对其加以完善。
