摘要
近年来由于信息技术的进步,采用计算机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.
