【摘要】 二十世纪以来世界科技发展迅速,计算机技术已经广泛深入到社会经济和人们的生活的各个领域中,算法科学随之应运而生。算法作为计算机科学的重要支撑性内容,发挥着越来越重要的作用,算法思想已经成为现代人应具备的一种数学素养。高中数学新课程改革后算法被列为高中数学课程新的双基内容。算法学习的现实意义不容忽视,它不但能够培养学生独立思考的能力,提高学生的逻辑思维能力,还能提高学生解决实际问题的能力,并为今后学习计算机程序设计打下基础。《普通高中数学课程标准(实验稿2003.4)》(以下简称为《数学课程标准》)把“算法初步”列入了必修课程的5个模块中(数学必修3),其引入在中学数学界引起了强烈反响,赞同者与反对派各执一词。的确算法是数学课程中新增加的内容,对教师来说很陌生,在实际的教学中并没有现成的经验可以借鉴,给教学带来一定困难。但高中引入算法的积极作用是不容忽视的,通过学习算法可以提高学生有条理地解决问题的能力,有助于促进思维发展,同时算法也址中国古代数学的主要思想。因此如何在课堂中实施“算法初步”这一新的内容已成为每个高中数学教师关注的焦点。本文立足于算法教学实践,从算法的概念,特征入手,研究新课程改革后普通高中引入算法的目的和意义；再结合算法在新课程标准中的要求和近几年算法在高考中的体现,通过问卷调查、学生测验方式进行调查研究,对学生的学习动机和基础学习情况做了全面的分析,并通过教案设计和课堂教学设计对高中算法教学现状进行深刻、全面、辩证地分析；最后对普通高中算法教学提出了几点建议：在课堂上要激发学生的学习兴趣,使学生主动的去发现问题,经过探索研究解决问题,并对学生完成任务的结果给予及时的反馈,体现出以学生为主体,教师引导参与的素质教育方式。更多还原

【Abstract】 With rapid development of world science and technology in the 20th century, computer technology has been widely applied to the economy and everyday life. algorithm has been appeared. Algorithm is playing a more and more important role, which is the most important and basic part of computer technology. So we must acquire the ability. After the reform of mathematics, Algorithm is considered as the essential part of the subject. We can not ignore the part it plays, because it not only can cultivate the ability of thinking for themselves and improve their logical mind, but also can provide a solid foundation for their studies.In" The Mathematics Curriculum Standard of Ordinary Senior middle School (Experiment,2003.4)" ( "Mathematics Curriculum stand" for short), "Algorithm accidence" is listed in the five modules of compulsory Courses (Compulsory Part 3 of Mathematics). But it has aroused strong reactions, there is many approver and opposition. Of course algorithm is a new content in mathematics course, It is very strange for teachers no existing experience can be used for reference during teaching process, most teachers have great difficulty in teaching and it can also lead to more challenges. However, we can not ignore the positive role of it, algorithm is added to the courses so as to improve the capability of solving the problems logically for students, it is also helpful to the promotion of the thought’s development, at the same time algorithm represents the important thoughts of the Chinese ancient mathematics. Therefore how to put algorithm in to practice has been a focus for every teacher in Senior High SchoolThis algorithm is based on teaching practice from the concept of the algorithm, feature. I introduce a purpose and significance of the new high school curriculum reforms in the algorithm, And combine with the standard algorithm in the new curriculum requirements and the embodiment of algorithm in college entrance examination in recent years, Through questionnaires and the student tests I conduct research on student motivation and do a comprehensive dialectical, and dialectical analysis in the basis of learning and teaching plans and classroom instructional design of the high school method of teaching status. Finally I make some suggestions on the method of teaching high school algorithm. In the classroom I stimulate student interest in learning so that students take the initiative to find problems, and solve problems through exploration and research, and give timely feedback results for students to complete the task so that the quality of teaching education shows that students are demonstrated as the main guide and teachers are participated in the teaching.更多还原
