摘　　要：互联网及信息技术在教育领域的广泛应用,为建立有效支持在线考试与测验的模式和方法提出了挑战和机遇。文中基于将考试/测验相关信息作为在线学习过程中重要资源的原则,探讨此类资源生命周期中的规划、建设、使用、分析等活动,提出一种支持多种教学和学习模式的在线考试系统模型,并在系统的安全访问控制中,针对传统的RBAC模型所存在的问题,采用改进的混合授权的扩展模型(ERBAC)式实现。通过资源共享课程建设和应用验证了这一模型和系统的有效性。The wide application of Internet and information technology in education field, put forward the challenges and opportunities for establishing the mode and method supporting the online examination and tests. Based on the principle of the examination/test related information as an important resource in the process of online learning, explored the planning, construction, use, analysis and other activities in the life cycle for such resources, and an online examination system model supporting a variety of teaching and learning mode was proposed, and used an improved mix granted extended model in the security access control system in order to solve the problems in traditional RBAC model. Then validated the effectiveness of this model and system by resource sharing learning construction and application.
