CAI为学生提供一个良好的个人化学习环境,综合应用超文本、多媒体、人工智能以及知识库等计算机技术,具有多样性、个别性、交互性、灵活性等特点。克服了传统教学方式单一、片面的缺点。它的使用能有效地缩短学习时间、提高教学质量和教学效率,实现最优化的教学目标。本文针对目前自带题库的CAI系统占用较大的存储空间,给操作者带来不便的弊病,重点介绍了笔者以设计“计算机基础考试模拟练习系统”为实例,为消除这一弊病而采取的对策:采用顺序文件来存储习题,充分利用了磁盘空间;设置题型编号K,题结构L,题型中的小题数I这三个变量作为题型标志,使程序设计简单明了,从而实现了CAI系统占用较小存储空间的目标。本文还简要介绍了“计算机基础考试模拟练习系统”的设计思路和主要功能。
CAI provides students with a good personal learning environment, comprehensive application of computer technology such as hypertext, multimedia, artificial intelligence and knowledge base, with diversity, individuality, interaction, flexibility and so on. Overcome the traditional teaching methods of single, one-sided shortcomings. Its use can effectively shorten the learning time, improve the quality of teaching and teaching efficiency, to achieve the optimal teaching objectives. This article focuses on the CAI system with its own test bank takes up a lot of storage space, to bring inconvenience to operators ills, focusing on the author to design “Computer Fundamentals Simulation System ” as an example, in order to eliminate this ills Take countermeasures: the use of sequential files to store exercises, take full advantage of the disk space; set the type number K, the title structure L, the type of questions I three variables as a question mark, the program design is simple, Thereby achieving the CAI system takes up less storage space goal. This article also briefly introduces the design ideas and main functions of “Computer Fundamentals Simulation Training System”.
