【摘要】 为了满足国内软件学院的需求,特别是面向软件工程系列课程案例教学的需求,提出并设计、开发了模拟现实项目开展过程的仿真教学系统基于项目的案例学习系统(PBCLS)。项目化案例对象(PBCO)为PBCLS的核心数据结构,承载着描述、定义、传播项目化案例知识的功能,同时也是PBCLS系统实现的重要保证。通过对项目组织结构的分析与提炼,对软件工程领域各种项目案例共性特点的提取,采用XML知识表示能力,描述和定义了PBCO的结构,并据此提供了一套实际的教学案例。研究结果表明,该方式具备描述普通项目案例的功能,保证了PBCLS原型的实现。更多还原

【Abstract】 Aiming at meeting the demand for domestic software college,especially meeting the needs of case teaching in software engineering courses,project-based case learning system(PBCLS) had been proposed,designed,developed,which would be able to simulate the process of real project.As the core data structure,project-based case object(PBCO) is carrying the function of describing,defining,disseminating project-based case knowledge,and it is also an important guarantee of the implementation of PBCLS.Furthermore,to define the structure of PBCO,organization and structure of project had been analyzed and refined,and common attributes and features had been extracted.Based on powerful knowledge representation capability of XML,PBCO has been described and defined by using XML,then a practical teaching case has been provided.The test results indicate that this method is capable of defining and describing some ordinary projects,at the meanwhile,it ensures the realization of PBCLS.更多还原
