中学数学中算法思想探讨

Exploring the Thought of Algorithms in Secondary School Mathematics

摘要: 在最新一部的课程标准中，算法思想成为义务教育阶段必要的教学内容。从目前中学的实际水平而言，教师对与算法部分内容讲解粗略，学生处于应试标准来学习该部分，也不足够详细，不能深刻理解最基本的算法步骤程序和思想方法。针对这一问题，笔者通过调查走访和座谈交流等一系列方式进行研究，总结当前教学现状和问题，并尝试对不同学段的学生和教师提供一些参考，为对应阶段教师的教学提供一些行之有效的思想。本文的基本思路为首先综述目前算法教学的现状和背景以及该课题的研究意义。再根据笔者在调查分析和走访座谈中发现的一系列问题进行分析和综合探讨。之后在根据现阶段的基本情况和突出问题结合自身经验，提出针对不同年龄段的教学建议或者相应的教学设计。

Abstract: In the latest curriculum standard, algorithmic thinking has become a necessary teaching content in compulsory education. In terms of the actual level of secondary schools, teachers’ explanation of the algorithm part of the content is sketchy, and students are in the examination standard to learn the part, and not detailed enough to understand the most basic algorithmic steps and procedures and methods of thought. To address this problem, the author through a series of survey visits and talks and other ways to study, summarise the current teaching status and problems, and try to provide some reference for students and teachers of different school years, to provide some effective ideas for the corresponding stage of the teacher’s teaching. The basic idea of this paper is to firstly review the current status and background of algorithm teaching and the research significance of the topic. Then according to the author in the investigation and analysis and visit to do talk found in a series of problems for analysis and comprehensive discussion. Afterwards, according to the current basic situation and outstanding problems combined with their own experience, we put forward different age groups of teaching suggestions or corresponding teaching design.
