1 问题教育部在2003年颁布的《普通高中数学课程标准(实验)》中,将算法列为高中数学内容的一部分.从2004年秋季开始,山东、广东、海南、宁夏四省区进行高中新课程标准试验改革,笔者所在学校使用了人教社 A 版教材,这套教材与以前老教材相比有较大的变化,其中变化之一是增添了“算法初步”一章.由于算法是高中数学中的新增内容,在数学教学中没有可以借鉴的经验,因此,笔者所在学校在2005年的教学
1 Problem The Ministry of Education in the “Ordinary High School Mathematics Curriculum Standard (Experiment)” promulgated in 2003 listed the algorithm as part of the high school mathematics content. From the fall of 2004, Shandong, Guangdong, Hainan, and Ningxia provinces and districts conducted high school education. In the reform of the curriculum standard test, the author’s school used a teaching material for the A version of the People’s Education Society. This set of textbooks has a major change from previous old textbooks. One of the changes is the addition of the “Preliminary Algorithms” chapter. It is a new addition to high school mathematics and there are no lessons to be learned from mathematics teaching. Therefore, the author’s school was teaching in 2005.
