摘要：随着网络技术的不断发展和现代教育理论的创新，网络环境下的个性化自主学习受到广泛关注。自适应测试作为一种“因人施测”的个性化测试形式也已成为测试研究的热点。
本文运用现代教学与学习理论，通过对自适应测试应用现状的研究，探索网络环境下测试、诊断、反馈及导学的理论和方法，寻求利用智能化的网络资源进行个性化自主学习的途径和方法。首先，提出从认知角度，诊断被试的认知风格，发现其知识结构中的缺陷，协助其完善知识结构的自适应测试。其次，运用数据库技术和网络技术着重进行试题参数分析和算法设计，尝试将这种带有个性化学习诊断和支持功能的在线测试理念应用于高中信息技术课程中。最后，实现了测试、结果反馈、知识讲解及练习等功能模块，实验结果表明本系统能够实现预设计的功能，在一定程度上减轻学生学习负担，提高学习效率。

Abstract：With the continuous development of network technologies and the innovation of modern educational theories, personalized independent learning has attracted extensive attention. Especially, Adaptive test has also become a hot spot in the testing research field, which is conducted with different approches on different testees.
Based on modern teaching and learning theories and researches of adaptive tests, this paper trys to explore theories and methods of test, diagnosis, feedback and guidance in the network environment and find ways to utilize intelligentized network resources for personalized independent learning. First, A kind of adaptive test that can diagnose testees’ cognitive style, find defects of their knowledge structures and assist them in perfecting knowledge structures is proposed on the view of cognition. Next, it attempts to apply the idea of on-line tests which afford personalized learning diagnosis and support into senior Information Technology curriculum by concentrating on using database and network techniques to analyse test parameters and design algorithm Besides, some critical funcional modules such as testing, result feedback, knowledge explainattion and practice modules are completed. Experiment results show that this work may alleviate burdens on students and improve their learning efficiencies to some extent.
Keywords: Adaptive Test; learning diagnosis; cognitive style; knowledge structure; Information technology curriculum
