面向多类终端的计算器自适应测试系统的设计与实现

Design and Implementation of Computerized Adaptive Testing System for Multi-Terminals

近年来由于信息技术的进步，采用计算器自适应测试进行评价得到迅速的发展;此外，移动技术的可用性也为评价提供了新的途径。文章设计并开发了面向多类终端的自适应测试系统，在项目选择过程中充分考虑了已有算法所存在的部分项目曝光率高、题库利用率低、内容平衡等问题，重新设计了项目选择引擎。通过该系统可以为形成性评估、总结性评估和自我评估提供支持。

In recent years due to the advances in information technology， the evaluation of the use of computer adaptive test has been developed rapidly. In addition， the availability of mobile technology provides a new way for the evaluation. This paper designed and developed adaptive testing system for multi-terminals， fully taken into account the problems in the item selection process， such as the high item exposure rate， low item pool utilization rate and content balance， so re-design the item selection engine. The system can support formative assessment， summary assessment and self-assessment.
