生态学视角下信息技术和语言测试深度融合研究

An Ecological Perspective of Integration between IT and Language Testing

适应性测试是信息技术与教育深度融合在测试领域的体现。基于测试的生态学视角，本文设计实施了适应性语言测试。通过改编现有试题进行题库建设降低了题库建设成本；采用以组为单位的跳转原则减少了对试题的需求数量。实验证明依据上述方法设计的适应性英语阅读测试具有良好效度和信度，为今后适应性语言测试在中小型测试中的推广提供了借鉴。

In-depth integration of IT and language testing is embodied by the application of adaptive test. Based on ecological perspective， this paper designs an adaptive English reading test. Firstly， the method of adapting existing material is proposed in order to cut the cost of item banking. Secondly， the design of jumping on the basis of a unit reduces the number of items needed in item bank. Empirical study shows that the English reading test with the above designing features reveals a sound validity and reliability.
