A new CAI system for concurrently assisting the programming exercises by many students has been studied, in order to greatly improve the educational quality of the exercises. The study has been focused on to clarify a suitable system architecture and to develop an effective technique for assisting a well structured algorithm description. Main results obtained are as floows :1. It was shown that the total behavior of the programming exercise was interpreted by a blackboard model when a "task", a tuple of student ID and exercise Id, was determined as the assisting and managing unit in the system. Next a new architecture for the assisting system was proposed on the basis of the "heirarchical multiplexed blackboard model", which was derived under the condition of various service programs with different access frequencies.2. A cooperative distributed technique for assisting structured description of algorithms was presented by paying attention to the heirarchical structure of the descriptions by the flowchart language. Next heirarchical diagnosing method, consisting of expression error check, structural error check and logical error check, was developed for detecting various faults existing in the flowcharts.

为了提高程序设计习题的教学质量，研究了一种新的多人同时辅助程序设计习题的计算机辅助教学系统。这项研究的重点是澄清一个合适的系统架构，并开发一个有效的技术，以协助结构良好的算法描述。主要结果如下：1.结果表明，编程练习的总行为解释的黑板模型时，一个“任务”，一个元组的学生ID和练习ID，被确定为系统中的辅助和管理单元。其次，基于“分层多路黑板模型”，提出了一种新的辅助系统的体系结构，该模型是在不同服务程序和不同访问频率的情况下推导出来的.针对算法描述的层次结构，提出了一种协同分布式算法结构化描述技术。其次，提出了由表达式错误检查、结构错误检查和逻辑错误检查组成的层次化诊断方法，用于检测流程图中存在的各种故障。
