高中数学新课程中算法教学现状的调查与分析

Survey and Analysis of Algorithm Teaching and Learning in High School in New Mathematic Curriculum

算法是当前高中数学课程改革中引入的新内容.经过对实验区师生的调查访谈发现,课程改革中有关算法的理念得到了广大师生的赞同.但是还存在以下问题:(1)学生对于算法概念的理解不够全面;(2)算法在计算机和相关数学内容中的应用很差;(3)教师在教学中获得的支持不足.这些问题主要是由于课程自身、教师观念,课程资源和教师培训几方面的原因造成的。

Algorithm was a new contents included in present high school mathematic curriculum. The result of the investigation indicated thai it was successful to involve contents of algorithm in high school mathematic curricula on the whole, Most teachers and students welcome the involvement of algorithm and agreed its educating significance, however, there were some problems in practice： firstly, students didn＇t understand the concept of algorithm completely; secondly, the combination of algorithm thinking and correlated contents, and the application of algorithm in the computer, the ancient algorithm content had not obtained deserved emphasis was not good; thirdly, teachers didn＇t gain sufficient support in teaching and train for them doesn＇t make sense. All these problems were caused by the following reasons： the owe of algorithm curriculum, teachers＇ notion, curriculum resources and teachers＇ train.
