A Framework for Policies and Practices to Improve Test Security Programs: Prevention,Detection, Investigation,and Resolution (PDIR)

Test security is not an end in itself; it is important because we want to be able to make valid interpretations from test scores. In this article, I propose a framework for comprehensive test security systems: prevention, detection, investigation, and resolution. The article discusses threats to test security, roles and responsibilities, rigorous training for everyone involved in testing, and an evaluation of current practices in test security. I call on everyone responsible for testing programs—the Association of Test Publishers, Council of Chief State School Officers, National Council on Measurement in Education, U.S. Department of Education, and state assessment program managers, their vendors, and the research community—to collaborate on guidelines and practices for security violation prevention, detection, investigation, and resolution.

The impact of immediate test score reporting on university students' achievement emotions in the context of computer-based multiple-choice exams

Test-taking is an emotion-laden event for many students. Typically, negative emotions are highest at the start of an examination and are replaced by positive emotions as the exam progresses. The impact of computer-based testing and immediate score reporting on students' emotions has not been examined. In Study 1, we evaluated university students’ emotions at the end of a computer-based exam and found positive emotions more strongly endorsed than negative. In Study 2, we replicated this finding and used a quasi-experimental pre-post design to examine how emotions changed in response to real examination scores. Exam scores presented immediately had significant positive effects on relief, pride, and hope and negative effects on anxiety and shame even after controlling for the corresponding emotion at the end of the exam. The one exception was anger, which was not impacted by examination score. No interaction effects were found.

《反对本本主义》:毛泽东思想形成的主要标志

所谓毛泽东思想的形成是指毛泽东思想的基本形态，也就是其主体部分和“活的灵魂”已经形成。从这一判断标准出发，在详细考察以毛泽东为代表中国共产党人的革命活动和理论贡献的基础上，可以看出《反对本本主义》的发表标志着毛泽东思想已基本形成。     

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。
