查询词典 hypothesis test

The aptitude and career interest were considered as the two dimension of the entrance guide system, and was proof-tested by the structural equation model, which results supported this two-dimension hypothesis. Accordingly, there were two parts in the guide system. One part was about the aptitude test, consisted of seven subtests: verbal reasoning, spatial imagining, mathematic reasoning, computer capacity, abstract reasoning, physical knowledge, and sentence recomposing. The other part was about the career interest test, including eight aspects: career longing, curriculum desire, entertainment after school, activity preference, job preference, work environment preference, self-estimate of one\'s abilities, and discuss future with someone else. After three times modification and testing, the psychometric indices of the guide system were become well and stable. Furthermore, the guide system was primarily launched into applying, with four typical case studies, the practicability and serviceability of the guide system was showed swiftly.The entrance guide system for junior high school students that was developed in this research was one-upping in the entrance guide field in China.

The core of test theory for a new generation of test is the combination of psychometrics and cognitive psychology, which is the key idea of the article .The article supposes there are four factors underlying response difficulty of Raven's Standard Progressive Matrices: figure complexity, figure format, transformation dimension, location factor. The hypothesis is tested by linear logistic latent trait model and proved to be valid.

本文在以认知和测量相结合为核心的新一代测验理论的指导下，从瑞文标准推理测验项目刺激特征的角度，对项目认知难度的影响因素进行了认知分析，提取出四个因素：图块繁简度、图块布局、变化维度、题序因子，结合线性逻辑斯谛克潜在特质模型对这四个因素进行了检验，证明提取出的四个因素是有效的。

Research also shows that in different test condition, sensitivity, accuracy, and stability of bending creep test at 0 C are better than that of bending test at -10C. Thus, bending creep test at 0C can preferably evaluate the crack resistance of asphalt mixture at low temperature.

结果表明，老化过程大大降低了沥青混合料的低温抗裂性能，0℃弯曲蠕变试验比-10℃弯曲试验对不同的试验条件的区分度更大，试验误差更小，稳定性更好，可较好地评价沥青混合料的低温抗裂性能。

Online learning must be the main stream and online test will substitute the traditional paper-and-pencil test in the future. In order to respond to the coming of online learning era, how to make good use of the Internet is an important issue. Teachers can design online test questions to effectively understand students' learning performance and control their learning condition. Then teachers can provide remedial programs. Therefore, developing a flawless online test system to satisfy users' request is a critical issue both in practical and academicals.

网路学习必然是未来发展趋势，线上测验也逐渐取代传统考卷测验方式成为主流，为因应网路教学时代来临，如何善用网际网路让教师得以藉由线上测验之试题设计，而能更有效进行测验与验收学生之学习成效，且充份掌握学生之学习情况，后续即能针对能力较弱之处进行补救教学，因此，建构完善的线上测验系统以符合使用者需求，对实务界及学术界来说，都是一项很值得进行研究之议题。

Another work of this paper is to study the continuous design of Test Automation. Common aspects of continuous design include the performance and maintainability of test automation system itself, the independence of test execution, and the analyzability of test result. This paper gives the concrete resolution of above four aspects, and also proposes other aspects need to be considered in continuous design, such as extendibility in future and capability to multi-product and multi-edition.
