Assessing Individual‐Level Impact of Interruptions During Online Testing

With an increase in the number of online tests, the number of interruptions during testing due to unexpected technical issues seems to be on the rise. For example, interruptions occurred during several recent state tests. When interruptions occur, it is important to determine the extent of their impact on the examinees' scores. Researchers such as Hill and Sinharay et al. examined the impact of interruptions at an aggregate level. However, there is a lack of research on the assessment of impact of interruptions at an individual level. We attempt to fill that void. We suggest four methodological approaches, primarily based on statistical hypothesis testing, linear regression, and item response theory, which can provide evidence on the individual‐level impact of interruptions. We perform a realistic simulation study to compare the Type I error rate and power of the suggested approaches. We then apply the approaches to data from the 2013 Indiana Statewide Testing for Educational Progress‐Plus (ISTEP+) test that experienced interruptions.

Revising the Online Classroom: Usability Testing for Training Online Technical Communication Instructors

ABSTRACT

This article reports on an effort by the authors to use usability testing as a component of online teacher training for their multimajor technical communication course. The article further explains the ways in which program administrators at other institutions can create their own usability testing protocols for formative online teacher training in course design and in principles of user-centered design.     

ASP在Online Testing System中的应用

随着Internet的日益发展、普及,人们对WEB的要求越来越高,需要灵活的动态网页技术。动态网页技术ASP具有保密性好、与所有脚本语言兼容、易编写、无需编译等特点,且ASP在与数据库的连接上采用ADO(ActiveX Data Objects)技术访问后台数据库,这些深受网页制作者的欢迎。在Online Testing System中动态网页制作中采用ASP,具有一定实用价值。

Discourse Patterns During Children's Collaborative Online Discussions

This article examines the discourse of 10 groups of children during text-based online discussions. Analysis of the discourse in the discussions showed that 8 different rhetorical moves, or argument stratagems, were used by most groups of children, whereas 3 other stratagems were used by 1 group. The use of argument stratagems snowballed; that is, once an argument stratagem emerged in a discussion, it tended to spread to other children in the Web group, and the likelihood that it would occur again remained high over the course of the discussion. Most stratagems began to spread when initiated by other children but not when introduced by the adult moderator. Children were eager to participate and displayed a high rate of participation in discussions with Webmates from distant classrooms. These findings suggest that collaborative online discussions may provide an effective instructional medium for promoting children's learning of reasoning strategies and thinking skills.

Toddlers Use the Number Feature in Determiners During Online Noun Comprehension

Function words support many aspects of language acquisition. This study investigated whether toddlers understand the number feature of determiners and use it for noun comprehension. French offers an ideal “test case” as number is phonetically marked in determiners but not in nouns. Twenty French‐learning 24‐month‐olds completed a split‐screen experiment. Looking times to target pictures were measured under 3 trial types varying in the degree to which the determiner matched the number displayed in the object(s). Children looked longer when the determiner matched the object(s), and were confused in trials of clear mismatch. Importantly, their processing resembled that of French adults ( D. Dahan, D. Swingley, M. K. Tanenhaus, & J. S. Magnuson, 2000 ). Thus, children understand the determiner number feature early in acquisition and use this knowledge to constrain online comprehension.     

论诉讼时效中断事由

诉讼时效中断与诉讼时效中止同为诉讼时效不完成制度，诉讼时效中断事由主要有权利人请求、义务人承认和起诉等几项。我国民法对这些事由的规定过于简单、不具体，而且某些事由的规定还欠科学。针对这些不足，结合外国民法相关规定，对我国诉讼时效中断事由提出了一些改进的设想。
