4、sDepartment of. Data structure is not only one of the core courses of Computer Science in UniversitiesIt is also a major choice for non computer majorsOne of the courses required. The course covers a large number of concepts, data structures, and algorithmsThe theory is strong and abstractEspecially
5、The understanding of the execution process of the algorithm description is difficult and important. In class teachingA lot of algorithms are impossible and impossibleDetail one by one. Our data structure teaching assistant systemSet data structure, algorithm demonstration and other lettersinterestOn
6、 a screen (e.g., input, prompt, etc.)Chinese subtitles are usedThe use of visual graphics to dynamically demonstrate the implementation of the algorithmRow processIt is very good for students to understand the content of the teaching materials, master the basic data structure and the implementation
7、of the corresponding algorithmHelping roleAt the same time, the system can be used in different levels of teachingIt is convenient for class teachers to explain and take lessonsReview, self-study.2 design ideasCourseware is an organic combination of two major kinds of information: teaching content a
8、nd teaching processThe purpose is to learn and teach according to certain theoriesLearning strategies will focus on teaching and difficult pointsTeaching is not easy to make clear content, with the help of computer demonstration. So weCompiledThe CAI system emphasizes the practicability while emphas
9、izing the advanced and scientific teaching. The development of this courseware satisfiesFollowing principles:(1) the main contents of this course should cover the wide coverage of the contents of the systemAnd combine the course selection teaching materialUse.CAn algorithm for describing data struct

11、ly play the effect of auxiliary teachingThe system uses a variety of demonstrations, such as the use of singleStep tracking, continuous execution, and spanning functions(or process)Call, and so on to demonstrate the specific implementation process of the algorithmAnd playDisplay mode can be changed
12、at any timeThe speed of the demonstration can be adjusted at any time.(3) man-machine interface, friendliness, system interface design follow the practical and convenient principleVarious operations are concise and clearThe. The courseware also has mouse interface and keyboard interfaceAn input from
