摘　　要：循环结构是高级计算机语言中的重要结构,由于语句跳转和变量频繁变化使得循环结构成为程序设计语言教学的难点,学生难于从循环结构中分析出正确的结果。针对该问题,提出一种循环结构的跟踪分析方法,以图表的方式跟踪循环结构和变量,顺序的方式描述变量变化规律,掌握变量变化之间的关系,使得教师教学和学生学习同步,提高学生分析程序的正确率和效率。通过教学和实验分析证明了该方法的有效性,取得了良好的教学效果,能够培养学生独立分析程序的能力。Cycle structure is important in advanced programming language. However,it is difficult to teach and comprehend for students and teachers due to jump construct and variable. So cycle structure becomes a teaching difficulty, most of students difficultly consult the right result of cycle structure. In order to deal with the question,put forward a kind of circular structure tracking analysis method, which u ses chart to track loop structure and variable, sequence to describe the change rule of variable, grasping the relationship between the varia bles, and makes the teachers teaching and students learning synchronization. The teaching method enhances the process accuracy and effi ciency for students. Through the teaching application and experimental analysis shows that this method is effective, and has achieved good teaching effect.
