【摘要】：随着基础教育课程改革的不断深化,教育信息化的进程加快,信息技术以势不可挡的步伐影响着数学教学.充分发挥信息技术在提升学生数学素养方面的作用,探索信息技术融入课程教学的途径成为重要的研究问题.函数概念是高中数学的核心概念,函数思想是高中数学的重要思想方法,掌握函数思想对于学生解决问题具有重要的意义.本课题分析了信息技术对函数概念教学的研究和对运用函数思想解决问题教学研究,希望在促进学生的数学素养方面做出探索.通过查找文献,采用调查法和案例分析法,得出本课题的主要结论有以下几点:(1)学生对函数重要性的认识不充分,对函数的发展历史了解不够,对函数的研究对象的特点以及与运动变化的关系认识不清晰.(2)教师对信息技术在表现函数基本特点,培养学生抽象概括能力以及运用函数解决问题能力等方面的作用的理解不够,信息技术的运用基本停留在演示和展示等方面.(3)先进的信息技术未必有先进的教学理念,教师的教学观念应与时俱进.依据现代教学理论,善于发挥信息技术的优势,在关注学生学习成绩的同时,应注重提高学生的综合素质.(4)函数是高中学生感到最难学的内容,信息技术融入函数概念的教学直观地展示变量之间的关系,化抽象为直观,化静态为动态,在运动变化过程中把握函数本质,发现变中不变的规律,深化对函数思想的理解.知识的理解是为了促进能力的提升,信息技术辅助函数思想解决问题,在问题解决过程中巩固函数概念,强化对函数思想的理解,作为日后解决问题的储备能力.
[Abstract]:With the deepening of the curriculum reform of basic education and the acceleration of the process of educational informatization, information technology affects mathematics teaching at an irresistible pace. It is an important research problem to give full play to the role of information technology in improving students' mathematical literacy and to explore the way of integrating information technology into curriculum teaching. The concept of function is the core concept of high school mathematics, and the thought of function is an important thought and method of high school mathematics. It is of great significance for students to master the thought of function for students to solve problems. This paper analyzes the research of information technology on the teaching of function concept and the teaching of using function thought to solve problems, hoping to explore how to promote students' mathematical literacy. By looking up the literature, using the investigation method and the case analysis method, the main conclusions of this subject are as follows: (1) the students' understanding of the importance of the function is not sufficient, and the development history of the function is not enough. The understanding of the characteristics of the research object of the function and the relationship between the research object and the motion change is not clear. (2) the basic characteristics of the information technology in the representation of the function are not clear. The function of cultivating students' abstract generalization ability and using function to solve problems is not enough, and the application of information technology basically stays in the aspects of demonstration and display. (3) Advanced information technology may not have advanced teaching ideas. Teachers' teaching ideas should keep pace with the times. According to modern teaching theory, we are good at giving full play to the advantages of information technology. While paying attention to students' academic performance, we should pay attention to improving students' comprehensive quality. (4) function is the most difficult content for senior high school students to learn. The teaching of information technology integrates the concept of function to show the relationship between variables intuitively, abstracts into intuitionistic, changes static to dynamic, grasps the essence of function in the process of motion change, finds the constant law in change, and deepens the understanding of function thought. The understanding of knowledge is to promote the improvement of ability, information technology auxiliary function thought to solve problems, consolidate the concept of function in the process of problem solving, strengthen the understanding of function thought, as the reserve ability to solve problems in the future.
