一、高中算法教学存在的主要问题笔者通过调查发现,由于诸方面的原因,算法思想的渗透尚不尽如人意,主要表现在:1.教师的算法素养.绝大部分数学教师,特别是中老年教师对程序设计缺乏了解,基本是靠边学边教、自我领悟,他们仅能处理简单的算法结构,而面对难度大、综合性强的算法题时则常常出错,甚至出现死循环.2.教师的思想定位.虽然算法思想与数形结合、分类讨论、 First, the main problem of teaching high school algorithm The author found through surveys, due to various reasons, the impermeability of algorithm ideas are not satisfactory, mainly in: 1. Teachers’ literacy. Most math teachers, especially in the Older teachers lack of understanding of programming, the basic is learning by the side, self-understanding, they can only deal with a simple algorithm structure, and in the face of difficult, comprehensive algorithm problems are often mistakes, or even death cycle.2. Teachers’ ideological position.Although the algorithm idea and the number of forms, classification, discussion,
